Abstract

(57) [Abstract] [Purpose] The purpose of the present invention is to provide a polishing and cutting tool,
To improve the operability by rotating the handle for holding and operating the main body according to the work. [Structure] The rotary handle of the present invention comprises a housing 1, a convex portion 1c, a handle 2, a concave groove portion 2c, a lock pin 7, an elastic body 8, a hole c, and a release pin 10.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of switch operability of tools for polishing and cutting work.

[0002]

[Prior Art]

 Conventionally, the position of the handle is fixed in this type of tool, and if the handle is fixed at a position that is easy to use for polishing work, the tool body is rotated and used during cutting work, It had the disadvantage that it was difficult to operate the retained switch.

[0003]

[Problems to be solved by the device]

 In a conventional tool for performing polishing work and cutting work, a handle for holding a switch is fixed to a housing with a screw, and there is a problem that the operability of the switch is poor depending on a tip tool attached to the tool.

An object of the present invention is to rotate a handle and improve operability of a switch according to work.

[0005]

[Means for Solving the Problems]

 The above object is achieved by disposing a handle rotatably in a housing constituting a tool, and disposing a position fixing lock pin in the housing and a device for pushing and releasing the position fixing lock pin in the handle.

[0006]

[Action]

 The main body holding and operating handle configured as described above is guided by the convex and concave grooves formed on the housing and the handle to rotate about the main body axis, and the rotation of the handle is fixed to the housing end face. This is achieved by providing a lock pin that

【Example】

 One embodiment of the present invention is shown in FIGS.

FIG. 1 is a structural model diagram of the present invention, the details of which will be described below.

2 and 3 show a state in which the handle position is rotated according to the present invention.

The central axis 1a indicates the central axis of the rotary drive shaft of the tool body, and the handle 2 rotates around the central axis 1a.

4 to 5 show a locking structure of the housing 1 and the handle 2 according to the present invention.

A circular convex portion 1c is provided on the end surface of the housing 1, and a concave groove portion is provided inside the halved handle 2 so that the housing circular convex portion 1c can be engaged and rotated. The movement in the direction of the central axis 1a is controlled by sandwiching the circular housing convex portion 1b.

6 to 7 show a structure for preventing the handle 2 from rotating with respect to the housing 1.

The lock pin 7 is projected from the housing end face 16 by utilizing the elastic force of the elastic body 8 at the end of the housing 1 to fix the position of the handle 2. When changing the position of the handle 2, the handle 2 is pushed by pushing the release pin 10 slidably disposed on the handle 2 by using the elastic force of the elastic body 8 and pushing the lock pin 7 into the housing end face 1b. It can be rotated.

[0015]

[Effect of the device]

 According to the present invention, by disposing the handle rotatably on the center line of the rotary drive shaft and by positioning the handle, the handle position can be changed even if the working direction is different depending on the tip tool. It is possible to improve the sex.
