[0028] A movable screw 20 is rotatably arranged between the left connecting plate 18 and the right connecting plate 19. The thread of the movable screw 20 passes through the middle of the fixed connecting plate 17. The end of the movable screw 20 rotates and passes through the left connecting plate 18. A second servo motor 21 is installed on the left connecting plate 18. The driving shaft of the second servo motor 21 is connected to the end of the movable screw 20 through a wound second transmission belt 22.
