Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a hook mounting structure for an electric power tool.

[Conventional technology]

For example, a conventional technique is disclosed in Japanese Utility Model Publication No. 48-83481. FIG. 3 is a partial side view of the disclosed structure, where 1 is a housing, 2 is a handle cover, and 3 is a hook. As shown in FIG. 3, in this structure, a plate-shaped hook is sandwiched between the housing 1 and the upper portion of the handle cover 2 and fixed.

[Problems to be solved by the device]

In the above structure, since the hook is arranged on the upper part, it has the advantage that it can be used by workers with either the left or right hand, but when the tool is temporarily stopped and the hook is hung on the waist belt. Each time, the tool has to be shifted by 90 °, and when using the tool again, the same 90
° My operability was poor because I had to move my hands to the shifted position. Further, since the hook is fixed only by sandwiching it, the larger the dimension indicated by A in Fig. 3, the larger the moment applied to the hook and the more unstable the fixing becomes. I have no choice but to make it smaller
As a result, it has a drawback that it cannot be hung on pipes used for scaffolding at construction sites.

An object of the present invention is to provide a hook mounting structure for an electric tool which is easy to use and can be securely fixed.

[Means for solving the problem]

To achieve the above object, the hook of the power tool of the present invention is a power tool including a handle portion, a housing, and a handle cover, wherein each of the flange portions is formed inside the housing and the handle cover. Each of the parts is provided with a through hole to the outside, a screw means is provided on the inner peripheral part of the flange part of either the handle cover or the housing, and a hook bent from approximately the center part is inserted from the through hole. It is characterized in that the hook is fixed to the screw means so as to be able to move back and forth, and the hook is fixed to the housing and the handle cover by a fixing means provided on one surface of the handle cover or the housing.

[Action]

According to the present invention, since the hook is arranged on the side portion of the tool and is fixed by the screw means, it is easy to use and can be securely fixed.

〔Example〕

An embodiment according to the present invention will be described below. FIG. 1 is a partial sectional view of an embodiment of a hook mounting structure of the present invention, FIG.
The figure is a cross-sectional view of the main part of FIG. In the figure, 1A, 1B
Is a flange portion, 2B is a through hole, 2C is a nut chamber, 3A is a screw portion, 4 and 5 are nuts.

As shown in FIGS. 1 and 2, the hook mounting structure of the present invention includes a housing 1, a handle cover 2, and a hook 3.
It consists of. The housing 1 has a flange portion 1A formed therein, and a through hole 1B with the outside is formed in the inner diameter portion of the flange portion 1A. The inner diameter of the through hole 1B is the hook 3
The size is determined so that the can be attached and removed freely and the rattling is as small as possible.

Similar to the housing 1, the handle cover 2 has a flange portion 2A and a through hole 1B formed therein. The inner diameters of the through hole 1B and the through hole 2B are the same. A nut chamber 2C for arranging the nut 4 is formed on the end surface of the flange portion 2A. The nut chamber 2C is formed at a substantially central position between the housing 1 and the handle cover 2. Handle cover 2
When assembled in the housing 1, the nut 4 is fixed to the nut chamber 2C by press fitting or the like so that the nut 4 does not easily come off. The same effect can be obtained by insert molding.

The hook 3 is bent at about 100 ° from the center, and a threaded portion 3A is formed at the tip. Place another nut 5 on the surface of the handle cover 2 and hook 3
Is fixed with a double nut.

In this embodiment, the double nut system can be used to more securely attach the hook 3, and the hook 3 can be fixed without using a tool such as a spanner. Since the hook is attached to the handle cover 2 side, it is a diagram for a right-handed person, but in the case of a left-handed person, it is necessary to reverse the hook attached location. In this case, loosen the nut 5, remove the hook 3 from the nut 4, and remove the handle cover 2
From the through hole 2B of the housing, insert the hook from the through hole 1B of the housing 1 on the opposite side, and screw it into the nut 4 again.
Finally, the position of the hook can be easily changed by tightening the nut 5. Since the distance between the tool and the hook 3 can be easily changed by changing the relative positions of the hook 3 and the nut 5, the hook can be an optimum one depending on the place where the tool is hung.

[Effect of device]

According to the present invention, since the hook is detachably arranged on the lateral portion of the tool and is fixed by the screw means and the fixing means, it is possible to provide a device which is easy to use and reliable.

[Brief description of drawings]

FIG. 1 is a partial sectional view showing an embodiment of a hook mounting structure for an electric power tool according to the present invention. FIG. 2 is an enlarged view of the handle portion of FIG. FIG. 3 is a side view showing a hook of a conventional electric power tool. In the figure, 1 is a housing, 2 is a handle cover, 3 is a hook, and 4 and 5 are nuts.
