[0015] Furthermore, a mounting hole is provided at the bottom of the vertical plate, and the mounting hole is used for connecting to an external device.

[0016] The utility model has the following beneficial effects: the utility model has a simple structure and is easy to operate. The clamping part on the transmission gear is driven by the driving cylinder to clamp and fix. It has the characteristic of a large opening degree. The driving cylinder drives the transmission gear to rotate, so that the opening angle of the two clamping claws can be maximized. Moreover, because gear transmission is the most stable transmission mode, it is not easy to be damaged when encountering external force impact, and the gear transmission itself has a certain self-locking ability. After clamping, the teeth bite each other and are not easy to loosen, which greatly improves the stability of the clamping mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
