Description

TECHNICAL FIELD OF THE INVENTION
[0001]
The present invention relates to a means for easily controlling the cutting depth when cutting a tree or the like using a hand-held saw.
[Prior art]
[0002]
Conventionally, when cutting a tenon with a hand-held saw, it is necessary to cut it halfway precisely, so that if you want to make a so-called stop cut, you must carefully look ahead and alternately look at the snap line drawn in front of you, but As shown in FIG. 1, there were many cases where the data was cut too much and failed. In the case of factory processing, dedicated electric machine tools were used. There are some prior arts that exist as saws for cutting off. For example, as in Japanese Utility Model Application No. 54-97724 (Japanese Utility Model Application Publication No. Sho 56-14001), the saw body and the handle are all fixed integrally. On the other hand, the body (stopper) moves in the lateral direction.
[Problems to be solved by the invention]
[0003]
It is an object of the present invention to provide a means that can be cut with a hand-held saw easily, accurately and without failure to a predetermined position, that is, a position parallel to a surface of a tree or the like at a predetermined depth.
[0004]
Another object of the present invention is to provide a hand-held saw that can be fitted to a right-angled, vertical cutting jig.
[Means for Solving the Problems]
[0005]
In order to achieve the above object, in the hand-held torso saw of the present invention, one or two saw plate holding members and stoppers are fixed to a handle, and a single-tooth or both-tooth saw separated from the handle is provided. The plate is loosely fixed to the saw plate holding member / stopper in the vicinity of both ends by a fixing member, and when the fixing member is loosened, the saw plate holds the saw plate on both sides of the saw plate holding member / stopper. It is movable across the entire width in a direction perpendicular to the member / stopper, and at least one tooth of the saw plate can be set to an arbitrary position while maintaining parallel to the saw plate / stopper. It is.
Also, in order to be able to be fitted with a known right angle cutting jig, the saw plate holding member / stopper has a gap between the saw plate and the saw plate except at both ends.
[0006]
Since the stopper can be set at an arbitrary position as described above, when the tree is cut forward and cut to a desired position, the stopper hits the tree and cannot be further cut.
[0007]
【Example】
FIG. 2 is an overall image of cutting a tree by the saw of the present invention. Some embodiments will be described below with reference to the drawings. In the first embodiment shown in FIGS. 3 and 4, the saw board 1 is fixed to the stopper 2 made of two long iron plates embedded in the handle 8. As shown, the saw plate 1 and the stopper 2 are fixed by the wing bolt 4 and the nut 5 as shown. At this time, the distance between the contact surface 6 of the stopper and the tooth tip 7 is adjusted and fixed so as to be equal to and parallel to the cutting depth when cutting the tree. The stopper made of two long iron plates serves two functions, that is, the holding of the saw plate 1 and the stopper for adjusting and fixing the cutting depth. It can also be applied to a kind of saw with a body made of thin saw boards.
[0008]
The perpendicular, vertical cutting jig 9 shown in FIG. 5 is known. When the saw 10 is put on the end face of the tree 10, a saw board is inserted into the gap 11, and the tree 10 is cut, it can be easily cut at right angles and vertically. At this time, in order to utilize the present invention as the second embodiment, the stopper 2A embedded in the handle 8A is one sheet as shown in FIGS. It is bent. The one-tooth saw plate 1A has two long holes near both ends thereof, and is fixed at an arbitrary position from the tooth tip 7A with a wing bolt 4 and a nut 5 as shown in FIG. A known right-angled, vertical cutting jig 9 can be used in this embodiment.
【The invention's effect】
[0009]
The present invention is configured as described above, and has the following effects.
[0010]
In order to make a cut to a predetermined depth, cutting with great care in the past, but still could not be corrected if it failed, the present invention makes it easy, accurate and without failure to cut Can be.
[0011]
Conventionally, a saw with a body uses a thin saw board, so it is easy to bend, and a back metal has to be attached to prevent this. In the present invention, the long iron plate has two functions, that is, the function of the back metal and the function of the stopper.
[0012]
Sawtooth includes a vertically-toothed tooth and a double-toothed sawtooth with laterally-toothed teeth attached to both sides of a sawtooth plate, but the present invention can also be applied to a saw with both teeth. In particular, a sawtooth with a torso cannot be used to make a two-toothed saw because a back metal is necessary, but the present invention makes it possible to manufacture a toothed sawtooth with two teeth.
[0013]
Recently, most saws are of the replaceable blade type, but the present invention can be implemented as a replaceable blade type saw, and a double-toothed replaceable blade saw can also be manufactured.
[0014]
When used in combination with a known right angle and vertical cutting jig, right angle and vertical cutting at a desired depth can be easily performed, which is extremely convenient for mortise processing and the like.
[0015]
Attaching a stopper to the saw board increases the bending strength of the saw, making it possible to make a saw made of a thin material.
