Abstract

(57) [Summary] [Object] The present invention provides two or more holding units provided inside the outer frame component of an electric power tool for holding the outer frame component and the components arranged therein. The purpose is to make the main body small by holding the parts or having a function other than the holding and effectively utilizing the internal space. According to the present invention, a holding part for holding two parts of a controller box 3 and an outer frame part in a housing 1 and a holding part for holding an outer frame part also functioning as a fulcrum 5a of a paddle lever in a controller box 3, A holding portion provided at one place has a structure having two or more functions such as holding two or more parts or holding parts and supporting point 5a of the paddle lever.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dual-purpose and multi-functional structure of a component holding portion of an electric power tool.

[0002]

[Prior art]

 As shown in FIG. 5, a conventional power tool includes a holding portion 10c for holding the controller box 3a in the housing 1a, a holding portion 10d for fastening the outer frame parts 11 to hold the outer frame part 11 in the housing 1a, and a paddle. Since the ribs 5f, which serve as the fulcrum of the lever 5e, are provided separately, it is necessary to provide a space for each of the ribs 5f. It had the drawback of burdening it.

[0003]

[Problems to be solved by the device]

 In the conventional technology, it is necessary to independently provide a holding part for each part in order to hold the inner parts of the outer frame with screws between the outer frame parts and to hold them in the main body with screws unique to the inner part. There was a problem that the space could not be used effectively and the main body became large.

An object of the present invention is to eliminate the above-mentioned problems of the conventional technology and effectively use the internal space to reduce the size of the main body.

[0005]

[Means for Solving the Problems]

 The above object is achieved by holding two or more parts by one holding part, and by using the holding part not only for holding the parts but also as a fulcrum of the paddle lever, so as to have two or more functions. It

[0006]

[Advantages] The housing configured as described above holds the controller box and the outer frame part, which holds two parts, and the holding part which holds the outer frame part, which also functions as a fulcrum of the paddle lever, in the controller box. Effectively uses the space inside the outer frame because the holding part provided in one place has two or more functions such as holding two or more parts or holding parts and the fulcrum of the paddle lever. To achieve downsizing of the main body.

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

FIG. 4 is a partial cross-sectional side view of the power tool according to the present invention. In the figure, a drive motor 2 axially supported in a housing 1, a controller box 3 to which a control circuit for controlling the drive motor 2 is fixed, a switch 4 mounted on the controller box 3, and a switch 4 interlocked with the switch 4. The paddle lever 5, the controller box 3, the switch 4, the outer frame component 6a that covers the paddle lever 5, and the rotation of the drive motor 2 are fixed to the spindle 8 via a speed reducer in the gear box 7. It is transmitted to the tip tool 9. FIG. 1 is a block diagram of the components within an outer frame component 6a showing an embodiment of the present invention. The holding portion 10a holds the controller box 3 and the outer frame component 6a in the housing 1. The holding portion 10b functions as a fulcrum 5a of the battle lever 5 and holds the outer frame component in the controller box 3. FIG. 2 is a sectional view of the holding portion 10a. The controller box 3 is sandwiched between the outer frame component 6a and the housing 1, and the outer frame component 6a and the outer frame component 6b are fastened with a screw 11a so that the controller box 3 can be connected to the controller box 3 at one holding portion. The outer frame part 6 a and the outer frame part 6 b are held in the housing 1. FIG. 3 is a sectional view of the holding portion 10b. The outer frame part 6a and the outer frame part 6b are held by the controller box 3 by fastening them with screws 11b so as to hold the controller box 3. At this time, the cylindrical holding portion 10b of the outer frame component is inserted into the sleeve 5b of the fulcrum 5a of the paddle lever 5, and the holding portion 10b also has the function of the fulcrum of the paddle lever 5.

[0009]

[Effect of device]

 According to the present invention, the holding of the controller box to the housing and the holding of the outer frame part to the housing can be performed by one holding portion. Further, since the holding part for holding the outer frame part on the controller box is also used as the fulcrum of the paddle lever, the space in the inner part can be effectively used and the main body can be downsized.
