At the same time, in the process of screwing in the fixing bolt 5, a rotatable driven rotating plate 601 is arranged on the side of the fixed push block 6, so that the friction between the fixed push block 6 and the fixing bolt 5 can be reduced, so that the wear between the fixing bolt 5 and the fixed push block 6 can be reduced.

[0026] like Figures 3 to 5As shown, a sliding guide rod 8 is fixedly connected to the inside of the second connecting block 3; the sliding guide rod 8 is arranged in parallel with the fixing bolt 5; the fixed push block 6 is slidably connected to the sliding guide rod 8; during operation, when the fixed push block 6 is pushed by the fixing bolt 5, the sliding of the fixed push block 6 is restricted by arranging the sliding guide rod 8 inside the second connecting block 3, so that the sliding guide rod 8 is less likely to tilt during the sliding process, and the fixed push block 6 is more stable when sliding.
