The connecting rod 18 is symmetrically installed on the outer side of the front end of the connecting ring 1 with the center of the limiting block 19 as the reference, and a rotational connection is formed between the connecting rod 18 and the limiting block 19. A rotational connection is formed between the transmission block 111 and the limiting plate 112, and a rotational connection is formed between the limiting plate 112 and the connecting plate 113. The rear end of the connecting plate 113 is fixedly connected to the front end of the clamping plate 15. The limiting plate 112 has an arc-shaped structure, and an active connection is formed between the limiting plate 112 and the clamping plate 15 through the connecting plate 113. The limiting plates 112 are symmetrically installed on the left and right sides of the front ends of the left and right clamping plates 15 through the connecting plate 113 in a left-right mirror symmetry manner.
