The joint bearing can rotate relative to the connecting shaft, so that during the telescopic rod extension and retraction process of the third telescopic cylinder 62, the pressing plate 33 is driven to rotate upward to open or rotate downward to press down.

[0026] As a preferred solution, two third telescopic cylinders 62 are provided on the mounting plate 32. When in use, the two third telescopic cylinders 62 are controlled to work synchronously at the same time, so that the rotation structure of the pressure plate 33 can be more stable, and the force of opening and pressing down can be greater. A rotating mounting seat 7 is provided on the mounting plate 32, and the third telescopic cylinder 62 is rotatably connected to the rotating mounting seat 7, and the rotatable direction of the third telescopic cylinder 62 is the same as the rotatable direction of the pressure plate 33.
