Abstract

(57) [Summary] [Purpose] By providing a guide pipe, it is possible to work safely and efficiently in screwing wood screws and the like. [Structure] A guide pipe that freely moves in and out is provided at a tip portion of a driver bit shaft, and a coil spring is mounted between the guide pipe and a spring receiver.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool in which a guide pipe (3) is provided at a tip portion (2) of a driver bit shaft (1) in order to easily and safely screw a wood screw, a tapping screw or the like.

[0002]

[Prior Art]

 Since the conventional driver bit did not have a guide pipe (3) at the tip (2), the tip (2) of the bit often came off.

[0003]

[Problems to be solved by the device]

 This had the following drawbacks. When using a conventional driver bit with a battery driver, etc., there is a case where the wood screw, etc. may come off from the bit tip (2) because there is no guide part. As a result, the product may be damaged or an accident may occur, especially in high-altitude work, which may cause a serious accident such as a fall. The present invention has been made to eliminate these drawbacks.

[0004]

[Means for Solving the Problems]

 A guide pipe (3) freely moving in and out is provided at the tip (2) of the driver bit shaft (1), and a coil spring (5) is mounted between the guide pipe (3) and the spring receiver (4). The present invention is a driver bit with a guide having the above configuration.

[0005]

[Action]

 The driver bit with a guide is attached to a battery driver, etc., and the longitudinal portion (9) of FIG. 2 is used for screwing in the screw, and the lateral portion (10) releases the guide pipe, so that a normal screwdriver can be used. Used as a bit.

[0006]

【Example】

 Hereinafter, examples of the present invention will be described. A metallic guide pipe (3) that can freely move in and out is provided at the tip (2) of the driver bit shaft (1), and a coil spring (5) is attached between the guide pipe (3) and the spring receiver (4). A guide groove (8) having a U-shape is provided at an arbitrary position on the side of the guide groove, and a stopper (7) adapted to the guide groove (8) is fixed via a stopper hole (6). This proposal has the above-mentioned structure. When using this, the driver bit with a guide is attached to the battery driver etc., and when the screw is screwed in, the stopper (7) of the guide groove (8) is guided. Set it in the longitudinal part (9) of the groove (8) and screw it into the tip (2) to screw it in, or if you want to replace the screw or use a screw with a large head, use the guide groove (8). ) Set the stopper in the short side portion (10), release the guide pipe (3) and use it as a normal driver bit. However, the guide pipe may be non-metallic.

[0007]

[Effect of the device]

 Since wood screws, tapping screws, etc. do not come off from the tip (2), work can be performed very safely and efficiently.
