Description

[Detailed Description of the Invention] Purpose of the Invention (1) Industrial Application Field The present invention is a power tool that is used in combination with a power tool that is generally used alone such as a plane, a drill, or a circular saw to fix these tools. This invention relates to a power tool that constitutes a stand that can be used.

(2) Conventional technology Power tools, such as planes, are not only used for cutting flat surfaces of plates; they can be applied in a variety of ways. Another common method is to move the plate and cut it.

This is not limited to planes, but stands are often provided for fixing various types of standalone power tools such as drills and circular saws.

However, conventional stand combinations do not function in any way other than simply as a means for fixing a power tool used alone, and the design goal has been to make them inexpensive, compact, and lightweight.

For this reason, the switch on the main unit can be used as is, and the switch on the main unit has
An ON lock was necessary.

However, the switch on the main body is configured to be turned on and off in a fixed working posture, and operation is not necessarily easy when the main body is fixed to a stand.

In particular, planes and circular saws have a switch inside the handle, and if the worker's position, posture, or direction changes when fixed to a stand, the switch cannot be easily operated. In this case, the plate was on top, that is, on the worker's side, and the switch was on the bottom, which was dangerous because the blade was on the worker's side.

The same is true for circular saws, as the switch is located under the table or base, and the blade faces the operator, making it dangerous to use. Ta.

(3) Problems to be Solved by the Invention The present invention relates to the configuration of a power tool that is used in combination with a stand and a main body, and provides a structure that is safe and easy to operate, and that allows a conventional main body to be used as is. The aim is to provide a power tool that can

Structure of the Invention (1) Means for Solving Problems The present invention attempts to improve safety and functionality by using the main body in its conventional state and configuring the stand so that it can be operated by a switch on the main body. There is.

The stand is provided with an operation section for operating the switch of the main body, and has a click configured to prevent the operation section from returning, so that a unique operation can be performed in opposition to the return elasticity of the switch. It is something.

(2) Embodiment The present invention will be explained based on an embodiment shown in the drawings. Fig. 1 is a side view of a power tool showing an embodiment of the invention, and Fig. 2 is a side view of the power tool. FIG. 3 is a perspective view of main parts.

In FIG. 1, an example of the power tool using a planer is shown, in which a planer body 1 has a plate 2,
3 faces upward, and the rotary blade 4 faces upward and is fixed.

The rotary blade 4 is provided with a cover 5 for safety, and the cover 5 is configured to cover the rotary blade 4 with the bias of a spring, and slides the workpiece onto the plates 2 and 3. When performing a cutting operation, the rotary blade 4 is pushed by the workpiece and is configured to come into contact with the workpiece.

Furthermore, the plane main body 1 is provided with a handle 6, and a switch 7 is provided inside the handle 6.
is provided.

The main body 1 is fixed to a stand 9 provided with a support column 8, and the stand 9 is provided with an operating section 10 so that a switch 7 provided inside a handle 6 can be operated.

Such a stand 9 is configured so that the plane main body 1 can be easily attached and detached, and is configured so that when the plane main body 1 is removed from the stand 9, the plane can be used alone.

In FIG. 2, the configuration of the operating unit 10 is such that a stand 9 is provided with two supports 11, and a cam 13 is mounted on a shaft 12 that is rotatably supported at both ends by the supports 11. The cam 12 is configured to push the switch 7 of the main body 1 in the direction of fixing the main body to the stand 9.

The operating portion 10 is provided with a lever 14 and a wide groove 15 of the support body 11 into which the lever 14 is fitted. By being formed of the material, the lever 14 is configured so that once it is fitted into the groove 15, it will not come off unless the lever 14 is forcibly pushed out of the groove 15.

That is, the lever 14 is inserted into the groove 15 of the support 11.
This constitutes a click, which has the effect of preventing the switch 7 from returning against pressure.

In addition, the lever 14 has holes 16 and 17 formed in the support body 11 that pass through the shaft 12 and the cam 13, respectively. then cam 13
acts on switch 7. When it moves to -, support 1
It is configured so that it does not deviate from 1.

(3) Effect In this configuration, when the power tool is used with the plane main body 1 alone, it can be used independently of the stand 9, and when it is desired to use the plane main body 1 fixedly, the power tool can be used with the stand 9. It can be used fixed to.

Then, the switch 7 is connected to the lever 14 of the operating section 10.
Since the switch 7 can be operated easily and safely, there is no need to directly operate the switch 7 on the back side of the plates 2 and 3 of the planer body 1.

Furthermore, when the switch 7 is pressed by the cam 13, the handle 6 of the plane main body 1 is pushed in the pressing direction, so it tries to escape from the cam 13, but this pressing direction and the plane main body 1 are fixed. Since they are in the same direction, they have the effect of not escaping easily.

Therefore, reliable operation can be expected, and problems such as malfunction of the switch 7 due to vibration or rocking by the workpiece can be avoided.

Moreover, by providing the lever 14 at an arbitrary position on the stand 9, operability can be improved.

Effects of the Invention According to the present invention, the operability of the power tool used in combination with a stand is improved, and safety is also improved, resulting in a power tool that is extremely easy to use for workers.
