Description

Technical Field

[0001] The utility model relates to the technical field of brake assembly assembly, in particular to a clamp used for assembling special-shaped handles. Background Art

[0002] The brake handle is a braking device for electric vehicles, motorcycles and bicycles. It is used to control the brakes of bicycles, motorcycles and other means of transportation and is an indispensable component in the vehicle structure.

[0003] Traditional brake handles usually consist of a brake handle and a mounting seat, which are hingedly connected by a pin or the like. When assembling, it is only necessary to clamp the brake handle and the mounting seat, and then insert the pin into the connection between the brake handle and the mounting seat. However, with the development of brake handles, there are now special-shaped handles that can adjust the moving distance of the brake handle, such as Figure 2 As shown, a toothed adjustment wheel is provided at the connection between the brake handle and the mounting seat. By turning the adjustment wheel, the relative angle between the brake handle and the mounting seat can be adjusted, so that the moving distance of the brake handle during operation can be adjusted. When assembling such a special-shaped handle with an adjustment wheel, it is difficult to assemble the adjustment wheel and the mounting hole that matches the adjustment wheel, and the adjustment wheel is affected by the mounting seat during assembly. Therefore, we propose a clamp for assembling special-shaped handles to solve the above problems. Utility Model Content
