DETAILED DESCRIPTION OF THE INVENTION [0001] The present invention relates to fields, parks, flower beds, gardens,
Or to remove weeds that have grown unnecessarily in golf courses, etc.
Related to weeding tools. [0002] 2. Description of the Related Art FIG.
It is typical one shown in As shown in FIG.
As shown in (b), a pair of holding pieces 1 for holding weeds.
a, 1b, arms 2a, 2b are integrated from the rear end respectively
And the holding piece 1a and the arm 2a are integrated with the holding piece 1a.
The holding piece 1b and the arm 2b are connected to the front ends of the arms 2a and 2b.
Cross near each other, and pivotally attach to each other at the intersection
It was done. Pressure between the arms 2a and 2b near the intersection
A compression coil spring 3 is provided, whereby the holding piece 1
a, 1b are biased in the opening direction, and more than a certain limit
A stopper 4 protrudes from the side of the arm 2a to prevent it from opening
Then, a restriction piece 5 is formed on a part of the other arm 2b,
At a certain opening, the regulating piece 5 comes into contact with the stopper 4 and
It is being restricted. The holding pieces 1a, 1
b is a plate having a thickness of about 1.0 to 1.2 mm,
At their inner ends so that they can abut each other.
You. [0003] However, a conventional disinfecting device is a pliers.
And the arm 2a, 2b
By gripping and narrowing the gap therebetween, the holding pieces 1a, 1a
b. Opening movement of the holding pieces 1a and 1b
The operation is performed by the action of the compression coil spring 3.
It has become. [0004] Therefore, in this weeding tool, weeding is performed as follows.
Work is performed. That is, first, the arc of this weeding tool
And the holding pieces 1a and 1b are connected to the compression cores 2a and 2b.
Keep it open by the action of Ilspring 3 with your fingers.
If you find a weed to hold and remove,
1a, 1b are advanced in the direction of the stem, and enter between them
By the way, if the arms 2a and 2b are gripped and closed,
The holding pieces 1a and 1b are also closed to sandwich the stem of the weed.
You. Next, the holding pieces 1a and 1b are pulled up as they are.
Thus, the weeds should be able to be pulled out. [0005] This type of conventional weeding tool is constructed as described above.
And used as described above,
Thus, there are various problems. First, the type and size of weeds
Despite the differences, etc., the stems and leaves are sandwiched
Weeding because it is configured to be pulled out by holding it between the holding pieces 1a and 1b
The efficiency is extremely bad. Therefore, in a pot with a small number of weeds
Weeding can still remove weeds in large areas such as fields and gardens.
It is completely unsuitable as a herbicide. In addition, the holding pieces 1a, 1
b has a thickness of about 1.0 to 1.5 mm as described above.
And weeds are sandwiched by lines rather than planes.
Therefore, thin stems are easily cut off.
As a result, it may not be possible to achieve the purpose of pulling out the whole root
You. Conversely, for fear of cutting the stem and the like, the arms 2a,
If the force applied to 2b is reduced, the holding pieces 1a, 1b
As a result, the pinching force on the stem is weakened, and
At times, slippage may occur between the holding pieces 1a, 1b and the stems.
And That is, at this time, the weeds
To easily achieve the purpose of pulling out weeds.
You will not get it. Thus, avoid cutting weeds, and
Pull out these little weeds to avoid slipping off
In order to put the stem etc. between the holding pieces 1a and 1b
It is very difficult to control the force of the fingers applied to the arms 2a and 2b.
It will be new. [0007] Further, the conventional herbicidal device is used for removing weeds in a lawn.
Removal cannot be performed properly. In the lawn fabric,
The roots cover the surface, while the miscellaneous
Since the grass is also deeply rooted, the holding pieces 1a and 1b
It is necessary to pierce the soil deeply, pinch the root, and pull it out
is there. However, with the conventional weeding tools as described above,
In rough soil, the holding pieces 1a and 1b are
It can hardly be closed and eventually functions as a weeding tool
Can not. Further, the conventional weeding tool has a holding piece.
Since the clamping direction by 1a and 1b is only one direction,
It is not possible to change the weed holding direction as necessary.
Therefore, between stone and stone, between stone and tree root, or tree root
In narrow spaces such as between spaces,
If the holding pieces 1a and 1b are difficult to open and close, and cannot be used
Often. Furthermore, since the holding pieces 1a and 1b are elongated,
It must be precisely aimed at the stems and roots of the grass
Is difficult for children and the elderly to handle
Also [0009] SUMMARY OF THE INVENTION The present invention
To solve various problems with weeding tools,And its components
Weeds and soil clogged during use in the slit of the holding piece
Or, a filter provided with foreign matter removing means capable of easily removing pebbles and the like.
Providing weeds is an issue to be solved. [0010] The gist of the present invention is as follows.
Is a pair of holding pieces that grab weeds and support them
An arm member that grips the pair of holding members.
The arm is used to open and close the piece.,The pair
Are formed of plate-like members capable of abutting against each other.
One of the holding pieces is extended in the tip direction and opened
One or more slits are formed, and the other
At the time of facing contact with the one holding piece,
Construct a ridge that fits into the lit, and at the tip,
At the time of face-to-face contact with the one holding piece, the one holding piece is
Weeding tool with a bent part that can be placed on the tipIn
To remove foreign matter adhering to the slit of the one holding piece.
To remove foreign matter,The foreign matter removing means,
Part is inserted into the slit of the holding piece, and the rest is the holding piece.
Foreign matter removal tip that is exposed to the outside of the
Therefore, the tip may be inserted inside the slit while the part is in the inserted state.
Foreign matter removal tip movably arranged from
A biasing means attached to the foreign matter removal tip,
A bias to move in the direction of the tip of one holding piece
Weeding device composed of force meansAnd the above-mentioned problem
Can be solved. The pair of holding pieces extend the arm member.
It may be constructed integrally with this, but weeds to be removed
Type, size, whether the weeding area is turf
To be able to select and set an appropriate holding piece according to the difference
In addition, it is more appropriate to adopt a detachable structure. [0012] The slit formed in the one holding piece,
The width may be the same from the inner end to the outer end opening,
The shape can be gradually widened in the direction
You. Or parallel from the inner end to the middle near the outer end,
It is good also as composition which spreads gradually from here. That is, toward the tip
Once the width of the slit is wide, the slit and the slit
And the rest between the slit and the outside
It becomes a pointed comb-like tooth, and this can be
This is convenient for piercing. Further, the pair of holding pieces and the other holding piece are
, When they come into contact with each other, their tips match
Length, and when they are so abutted, the other
The bent part of the holding piece almost abuts the tip of the one holding piece
It is best to be in a state. Then the above
The bend is on the inside, that is, on one side
It is appropriate to bend. [0014] [0015]AlsoThe foreign matter removing chip is a plate-like member.
Remove protrusions on one side with the same number of slits and corresponding intervals
Protrude and move the removal projection to the slit
Insert freely. At this time, the foreign matter removal tip
Arranged so that the surface is perpendicular to the outer surface of the holding piece, for example,
The tip of the slide bar is fixed on the back surface. This slide

Similarly, advance to the guide cylinder arranged in parallel with the outer surface of the
Retractably penetrate and slide with the rear end of the guide cylinder
A pulling body connected to the collar body at the rear end of the rod
A configuration in which an il spring is inserted can be employed. like this
Then, the foreign matter removing chip attempts to retreat the chip.
As long as no external force is applied, move to the front side,
Hold the moving state. Note that the above slide bar and guide
The cylinder, the collar body and the tension coil spring are provided with the urging means.
It constitutes. In addition, the foreign matter removing chip
And a spring between the front end of the guide cylinder and
In this case, a compression coil is used instead of the tension coil spring.
It goes without saying that a spring will be adopted. As the arm member, for example, a pair of
The arm pieces cross each other on the way and rotate at the intersection
Scissor-shaped members or side surfaces that are freely pivoted
A member having a U-shape as viewed from above can be employed.
In the former case, between the two arm pieces near immediately after the intersection
For example, insert a compression coil spring or
Arm members, such as by disposing a torsion coil spring at the attachment
The ends of both arm pieces that make up the
Should be energized as follows. In the latter case,
By configuring the U-shaped arm member with a spring material,
So that it stays U-shaped unless force is applied.
Is appropriate. [0017] The present invention is constructed as described above.
As such, weeds of various sizes can be easily distributed in areas of various aspects.
Can be removed. For example, when removing large-sized weeds
First, with both holding pieces open, slit
With the holding piece on the lower side, look at the root of the weed.
And insert it into the soil. The insertion depth of the holding piece is
It is to be inserted deeper and distant as it is larger. Next
Squeeze the arm member firmly to narrow the gap, and

It is an extension. The two holding pieces 11a, 1
1b, when the arm member 12 is gripped and strongly pressed,
In this example, so that the entire inner surface is in contact with each other,
One holding piece 11b is
It is extended in a state of being bent outward by the angle θ. In addition,
The other holding piece 11a of the pair of holding pieces 11a, 11b
Are two slits 13, 1 extending parallel to the tip
3 and the other holding piece 11b facing this is formed.
Protrusions 14, 14 are formed at corresponding positions on the inner surface. Up
The slits 13, 13 are open at the tip of the holding piece 11a.
It is a configuration that is open. Further, the one holding piece 11b is
Is placed on the tip of the other holding piece 11a.
The bent short plate 15 is formed. [0027]referenceIn the example,
Can be used for grass removal. For example, large size
When removing weeds, first, the two holding pieces 11a, 1
With slits 1 and 13 open, slits 13 and 13 are formed.
With the holding piece 11a down, look at the root of the weed.
Into the ground. The insertion depth of the holding piece 11a
The bigger the grass, the deeper it shall be inserted from a distance.
Next, squeeze the arm member 12 tightly to narrow the gap therebetween,
The stems and leaves of the weed are sandwiched between the holding pieces 11a and 11b from above and below.
When it is pulled or inserted in this state
The weeds of interest by raising
Can be removed. Before removing small-sized weeds,
In order to open and close the holding pieces 11a and 11b in the horizontal direction,
Use this weeding tool to remove large-sized weeds.
Use it after rotating 90 degrees. And both holding pieces 11
a, 11b are moved closer to the ground surface,
Weeds that are close to the root of the rising weed and are the target weeds
On the stalk between the two holding pieces 11a, 11b,
The arm member 12 is squeezed firmly, and both holding pieces 11a, 11
In b, the stem and leaves near the root of the weed are sandwiched from both sides. So
After that, pull the weeding tool in the appropriate direction as it is,
Elephant weeds can be pulled out reliably and easily with their roots
You. When removing small-sized weeds,
Operation in the same way as when removing large weeds
It goes without saying that they can be pulled out without any further action. As described above, one of the holding pieces 11a is placed underground.
When weeds are to be pulled out after insertion,
Slits 13 and 13 are provided on the holding piece 11a so that
Since it is shaped like a loop, it can be easily inserted.
Also, the roots or stems can be held by the slits 13, 13.
Is possible with the other holding piece 11b.
Is designed so that both abut each other on all inner surfaces
In addition to increasing weed retention,
So that weeds to be extracted
Does not easily occur. The slit 13 of one holding piece 11a,
13, the other holding piece 11b has ridges 14, 14
Are formed, and these are mutually held by the holding pieces 11a and 11b.
When you make contact with each other,
The weeds that have become inserted during
And both holding pieces 11a and 11b. Again before
A bent short plate 15 is formed at the tip of the holding piece 11b.
When the two holding pieces 11a and 11b are brought into face-to-face contact
Since it is shaped to cover the tip of the other holding piece 11a,
When the weeding tool is pulled toward the user,
Weeds pinched by a and 11b easily come off from the tip side
There is no such thing as. Next, based on FIG. 2 to FIG.reference
An example will be described. This is because the holding pieces 21a and 21b are
