[0024] Specifically, there are two mounting frames 51, which are symmetrically arranged with respect to the base 1. A rotating hole is opened on the surface of the support plate 52, and the driving screw 53 is rotatably connected to the inner wall of the rotating hole. The driving screw 53 passes through the side surface of the support plate 52. Through the cooperation between the mounting frame 51 and the support plate 52, the position of the driving screw 53 can be supported and restricted, thereby ensuring the stability of the supporting screw when in use.
[0025] Specifically, the cross 54 is located on the inner wall of the mounting frame 51 , and there are four push rods 55 . The four push rods 55 are diagonally arranged with respect to the cross 54 , and the push rods 55 are slidably connected to the inner wall of the mounting frame 51 .
[0026] In this embodiment, the cross 54 can be used to drive the four push rods 55 to move synchronously under the action of the driving screw 53, so as to achieve the effect of pushing the connecting plate 56.
[0027] Specifically, the connecting plate 56 abuts against the side surface of the mounting frame 51, and the clamping plate 57 abuts against the upper surface of the base 1.
