[0005] A first limiting recess is arranged on the left side of the first fixing groove, a second limiting recess is arranged on the left side of the first limiting recess, a stop platform is arranged on the right side of the second limiting recess, an anti-slip pad is arranged on the front surface of the stop platform, and a support platform is tilted downward at the rear side of the stop platform.
[0006] According to an embodiment of the utility model, the workbench, the fixing plate, the second limiting recessed platform, and the stop platform are integrally formed.
[0007] According to an embodiment of the utility model, the second limiting recessed platform is higher than the first limiting recessed platform, and the first limiting recessed platform is threadedly connected to the workbench.
[0008] According to an embodiment of the utility model, the second limiting recessed platform and the stop platform are tightly connected.
[0009] Compared with the prior art, the present application can obtain the following technical effects:
[0010] 1) By placing the limit rod in the front side of the camshaft, the limit rod and the stop platform play a stop role on the camshaft, making it difficult to shake, and further fixing the camshaft by setting the first fixing groove and the second fixing groove. Finally, the first limit boss and the second limit boss are used to make the clamp better fit the shape of the camshaft so that there is no gap between the two, thereby better fixing the camshaft.
[0011] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above technical effects at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
