The connecting columns 212 are arranged on the side wall of the mounting plate 1 far away from the actuating cylinder 31, the connecting columns 212 are circumferentially and uniformly distributed by taking the piston rod of the actuating cylinder 31 as a center, and each connecting column 212 is parallel to the piston rod of the actuating cylinder 31. The fixing plate 211 is located on one side of the mounting plate 1 away from the actuating cylinder 31, and the fixing plate 211 is in screw connection with the connecting posts 212 through screws. A through hole 4 is penetratingly formed at the center of the fixing plate 211, and the through hole 4 is horizontally formed to be opposite to the piston rod of the actuating cylinder 31. Two groups of guide pieces are arranged on the inner hole wall of the through hole 4 and are distributed in an up-and-down symmetrical mode. Each group of guide pieces comprises two guide strips 7, and the two guide strips 7 are distributed in bilateral symmetry. The guide strips 7 are obliquely arranged, and the distance between the guide strips 7 in the upper and lower groups of guide parts is gradually reduced towards one side far away from the mounting plate 1.

In the present embodiment, the two clamping jaws 22 are symmetrically distributed up and down with the through hole 4 as the center. One end of the clamping jaw 22 is connected in the through hole 4 in a sliding manner, and the other end of the clamping jaw 22 is provided with a stop block 8, wherein the stop block 8 is used for abutting against the mounting plate 1 and limiting the clamping jaw 22 to continuously penetrate into the through hole 4 in the process that the clamping jaw 22 penetrates into the through hole 4.
