[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric screwdriver, and more particularly to a grip device for an electric screwdriver which can easily change a vertically used electric screwdriver to a horizontally used electric screwdriver.

[0002]

2. Description of the Related Art There is known an electric screwdriver having a substantially cylindrical main body, which is used by vertically arranging the main body (hereinafter referred to as vertical use). In addition, depending on the place where the electric screwdriver is used in the portrait orientation, it may be more convenient to use the main body in the landscape orientation (hereinafter referred to as “horizontal orientation”). Therefore, a device has been developed in which a grip is attached to the main body to change the usability for use in a horizontal direction.

[0003]

There are two types of vertical electric drivers: a trigger type for starting by turning on a trigger switch and a push type for starting by pushing a bit at the tip of the main body. For example, in the trigger type, the trigger switch is attached to the side of the main body, and the shape is different from that of the push type. Therefore, the grip for changing the use to the sideways type is also different between the trigger type and the push type. Moreover, in the trigger type, a switch (auxiliary switch) interlocked with the trigger switch must be separately provided at an appropriate position in accordance with the lateral use in order to turn on the trigger switch when the lateral use is performed. Under such circumstances, dedicated grips are separately prepared for the trigger type and the push type, and the cost is accordingly higher, which is a problem. So, this idea is
It is an object of the present invention to provide a grip device for an electric screwdriver that can be used sideways for both a trigger type and a push type.

[0004]

That is, the present invention relates to either a vertical type trigger type main body which is started by a trigger switch or a vertical type push type main body which is started by pressing a bit at a tip. A grip device for an electric screwdriver that uses an electric screwdriver sideways by attaching a gripping body for gripping, wherein the gripping body includes a detachable auxiliary switch interlocked with a trigger switch, and the push-type main body includes a grip. When the body is mounted, the auxiliary switch is removed, and a cover is attached to the removed portion, so that the switch is used also as a trigger type.

[0005]

The grip device of the electric driver according to the present invention can be used sideways simply by attaching the grip body provided with the auxiliary switch to the trigger type body. In the push type main body, the auxiliary switch may be detached from the grip main body, and a cover may be attached to the detached portion, so that the grip body may be attached to the main body.

[0006]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a grip device for an electric screwdriver according to a first embodiment of the present invention, in which a pair of grip bodies 2 are sandwiched from both sides by a substantially cylindrical trigger type main body 1. . Note that reference numeral 3 in the drawing denotes a trigger switch. The grip body 2 is attached by screws 2a to 2d with the trigger switch 3 sandwiched in the middle as shown in FIG. 2 in order to prevent the main body 1 from rotating. An auxiliary switch 4 and a compression spring 5 are attached to the grip body 2. The auxiliary switch 4 is rotatably mounted with the pivot 4a as a rotation fulcrum. When the auxiliary switch 4 is pushed clockwise with a finger against the elastic force of the compression spring 5 in FIG. It is supposed to.

Next, a second embodiment of the present invention will be described. FIG. 3 shows a grip device for an electric screwdriver according to a second embodiment of the present invention. The grip device has a configuration in which a pair of grip bodies 2 are sandwiched between push-type bodies 6 from both sides. As the grip body 2,
The auxiliary switch (see FIG. 2) 4 is removed, and a trigger cover 8 is attached to a portion that has been the rotation fulcrum 4a with a screw 7 or the like. This grip body 2 is shown in FIG.
As shown in FIG. 3, the notch 2e having an arc shape is engaged with the projection 6a projecting from the main body 6 due to the structure of the motor.
It is prevented from turning around.

[0008]

As described above, according to the grip device of the electric driver according to the present invention, when the grip body is mounted on the trigger type main body, the auxiliary switch is kept mounted, and the grip body is mounted on the push type main body. When mounting, simply remove the auxiliary switch and replace the cover, and the grip body can be used for both sides, so that the cost is reduced and the need to prepare two types of dedicated grips is eliminated.
