Due to the sliding connection between the lifting plate 9 and the lifting seat 4, the lifting screw 8 drives the lifting plate 9 to move up or down.

[0035] Reference Figure 1-3 The fixing mechanism includes two fixing screws 16 symmetrically connected to the base 1 for rotation, one of the fixing screws 16 is fixedly connected to the output shaft of the fixed motor 3, one end of the two fixing screws 16 is fixedly connected to a synchronous wheel 17, and a synchronous belt 18 is connected between the two synchronous wheels 17. Both ends of the two fixing screws 16 are threadedly connected to the limit plates 19, and the four limit plates 19 are threadedly connected to the two fixing screws 16, so that the two fixing screws 16 drive the four limit plates 19 to approach or move away from each other, and the thread directions at both ends of the two fixing screws 16 are opposite to the thread directions of the four limit plates 19. Two connecting plates 20 are fixedly connected between the four limit plates 19, and a clamping ring 21 is fixed on the opposite side of the four limit plates 19, and the four clamping rings 21 are all arc-shaped.
