Description

Open end wrench structure

The invention relates to an open-end wrench structure, in particular to an open-end wrench structure, the first rotating part is provided with a first layer and a second layer and a groove, and the first layer has a first layer The first bevel and the groove have reduced material and weight.

As previously known, the conventional open-end wrench structure, such as U.S. Patent No. 463,137, is based on the structure shown in Figure 1. The wrench is an open-end wrench and the wrench is provided with a handle of appropriate length a. The two ends of the shank a are provided with the rotating portions b and c, and the rotating portions b and c are slightly open-shaped, and the thickness of the rotating portions b and c is shown by the side view of Fig. 2 The thickness of the shank portion is greater than the thickness of the shank portion a, and the thicknesses of the slewing portions b and c are the same, that is, the upper and lower sides of the rotating portion b and the c are parallel, and as shown in the third figure, the rotating portions b and c are A recessed recess is provided.

However, the structure of the patent is missing in that the rotating portions b and c are provided with recessed grooves, the grooves make the wrench tough and can reduce the amount of material and the overall weight, but the groove is limited by the rotation It is impossible to have a large volume in the range of b and c, and the effect of reducing the material is still quite limited.

Another Taiwan bulletin number I312716, patent name: open-end wrench, please refer to the second figure, the plane 32 of the open end 24 is provided with two recesses 40, which are basically the same as the above-mentioned US patent 463137 The disclosed grooves are of the same structure and thus have the same defects.

In view of the structure of the above-mentioned conventional open-end wrench tool, the inventors have years of experience in related industries, and finally have an open-end wrench structure product.
