The guide rod 40 is transversely arranged in the guide hole and is connected with the inner wall of the guide hole in a sliding manner.

The pressing plate 50 is disposed between the first fixing plate 20 and the second fixing plate 30 in the longitudinal direction. The pressing plate 50 is fixedly connected with the guide rod 40, a limiting space 51 is formed between the pressing plate 50 and the second fixing plate 30, and the limiting space 51 is adapted to a workpiece to be processed. A slot 52 is formed between the pressing plate 50 and the first fixing plate 20.

The spring 60 is sleeved on the guide rod 40, a first end of the spring 60 is fixedly connected with the first fixing plate 20, and a second end of the spring 60 is fixedly connected with the pressing plate 50.
