[0024] First, the specific structure of the stretching component 3 and the clamping member 2 is disclosed. The stretching component 3 includes a moving seat 301, and a mounting frame 302 is fixedly installed on the top of the moving seat 301. The outer surface of the mounting frame 302 is provided with a placement opening 303 for installing the clamping member 2.
