Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tool holder for carrying a portable electric tool such as an impact driver.

[0002]

2. Description of the Related Art Conventionally, a portable electric tool such as an impact driver having a high work efficiency has been widely used for tightening screws, drilling holes, etc. at a construction site or various construction sites. In order to carry such an electric tool, for example, a tool holder 50 as shown in FIG. 7 is known. The tool holder 50 is attachable to a belt 51 wound around the waist of an operator and has a bag portion having openings formed at the top and bottom, and the opening of the bag portion is wide at the upper side. The shape is such that the lower part is narrowed. Then, insert the tool shaft of the electric tool 52 from the upper opening,
By exposing the grip portion 53 to the outside of the bag portion of the tool holder 50 and holding it, the grip portion 53 can be easily taken out and stored.

[0003]

By the way, a rechargeable battery 54 is often attached to the extended end of the handle portion 53 of the portable power tool 52, and the battery 54 has a heavy weight. When the operator releases the power tool 52 and performs various operations, the power tool 52 easily falls in the direction of the arrow in FIG. 7 due to the weight of the battery 54.
There is a problem in that it easily comes off from the tool holder 50 and falls. Further, in order to prevent this drop, when the electric tool 52 is pushed deep into the tool holder 50, in some cases, the operation switch on the upper part of the handle may cause the tool holder 50 to move.
There is also a problem in that the tool axis may be pressed by the tool to run unintentionally and the tool shaft may idle.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to eliminate the problem that a portable power tool falls off a tool holder of an operator and falls, and prevents the problem that an operating switch operates unintentionally.

[0005]

In order to achieve the above object, according to the present invention, a motor portion and a tool shaft portion are arranged in a straight line, and a handle portion extends in an intersecting direction from an intermediate portion thereof to extend the handle portion. In a tool holder for a worker to carry a portable power tool with a battery attached to the outgoing end, a base plate is provided on which a belt passing portion through which the worker's belt can be passed is provided, and on this base plate, A first receiving portion capable of supporting a large-diameter portion of the tool shaft portion from below in a state where a part of the tool shaft portion is inserted, and a portion of the handle portion near the battery side from a lower side surface portion. A second receiving portion that can be held over the entire length is provided.

Then, the tool holder is set at the waist position of the operator by passing the belt through the belt passing portion of the base plate,
The tip of the tool shaft portion is inserted into the first receiving portion to support the large diameter portion of the tool shaft portion with the first receiving portion, and at the same time, the portion of the handle portion close to the battery side with the second receiving portion. If it is supported, the vicinity of the heavy battery is supported, so that it is possible to prevent a problem that the electric tool tilts due to the weight of the battery and falls from the tool holder. Further, since the power tool is held in close contact with the worker's body, the worker does not hang up or become unstable when performing various operations, and does not disturb the work.

Here, the first receiving portion has a circular ring shape or a shape close to this so that the large diameter portion can be locally supported from below by inserting the small diameter portion at the tip of the tool shaft portion. It is preferable that the second receiving portion is formed with a substantially U-shaped portion that matches the outer shape of the approximate handle portion so that the side surface portion can be locally retained from the lower side of the handle portion. . In addition, by locally holding the operation switch in this manner, it is possible to suppress a problem in which the periphery of the operation switch is opened and unintentional operation is performed.

Further, in the present invention, the base plate is provided with a third receiving portion capable of holding the side surface portion of the motor portion. As described above, by providing the third receiving portion that receives the side surface portion of the motor portion, it is possible to prevent a problem in which the electric tool falls sideways and falls from the tool holder, so that the fall can be prevented more reliably.
