Problems solved by technology

[0005] The purpose of the present invention is to provide an elongated wrench combination structure. The technical problem to be solved is that, in the existing wrench structure with a long handle, the material consumption causes the problem of high raw material cost, and the forged The degree of difficulty is relatively high, which creates a burden on production costs, and the use of tight fitting methods is prone to loosening or shrinking into the handle, which is difficult for industrial use, so it needs to be improved urgently

Embodiment Construction

[0017] Refer to image 3 , The present invention includes a first pulling member 10, a second pulling member 20 and an extension member 30; among them:

[0018] Please refer to Figure 4 versus Figure 5 The first pulling member 10 has a first end and a second end. The first end is provided with a pulling portion 11, and the pulling portion 11 is used to turn a screw or a nut. The second end of the first puller 10 forms a connecting portion 12, and the first puller 10 defines a consolidation groove 13 penetrating the upper and lower sides of the connecting portion 12.

[0019] The second flipping member 20 has a first end and a second end. The first end is provided with a flipping portion 21, and the flipping portion 21 is used to turn a screw or a nut. The second end of the second puller 20 forms a connecting portion 22, and the second puller 20 defines a fixing groove 23 penetrating the upper and lower sides of the connecting portion 22.

[0020] The extension member 30 has a fir...

Abstract

The elongated wrench combination structure of the present invention includes a first wrench, a second wrench and an extension piece; one end of the first wrench is provided with a wrench for turning screws or nuts One end of the first wrenching part is different from the wrenching part to form a connecting part, and the connecting part is provided with a consolidation groove; one end of the second wrenching part is provided with a wrenching part, and the other end forms a There is a connecting part with a consolidation groove; both ends of the extension piece are provided with a connecting groove, and the two connecting grooves are used for inserting the connecting parts of the two pulling parts. The position of the fixing groove of the first triggering member is punched with a fixing part for combining in the fixing groove of the second triggering member; thereby obtaining a stable bonding structure and a smooth and beautiful appearance extension wrench.

Description

Technical field [0001] The invention relates to an elongated wrench, in particular to an elongated wrench coupling structure with a stable coupling structure. Background technique [0002] Wrenches are a necessity for the people’s livelihood in the field of hand tools, and Taiwan’s hand tool industry has become the world’s leader in the production of wrenches. There are many types of wrenches, and there are hundreds of related patent cases. It is a narrow field in the industry, so innovation and reform are more driven by small changes. It is a route that is not easy to expand. However, small improvements still contribute to users, which is a commendable thing. [0003] Please refer to figure 1 Shown is a wrench 1 with a long handle. The wrench 1 has a longer handle than a conventional wrench for use in special occasions. Although this kind of long-handle wrench 1 is suitable for special occasions, the biggest problem encountered in the production process is the increase in mater...
