[0023] The side frames 8 are arranged on the left and right sides of the rotating motor 7, and a slide groove 9 is opened inside the side frames 8, a screw rod 10 is installed inside the slide groove 9, and the lower end of the screw rod 10 is connected to the servo motor 11, the top of the screw rod 10 is rotatably connected to the inner wall of the slide groove 9, and the lower end of the screw rod 10 passes through the lower surface of the side frame 8 through a bearing and is connected to the output end of the servo motor 11. The servo motor 11 is started to rotate the screw rod 10, so as to control the lifting movement of the slider 14. A pulley 12 is fixed to the outer side of the lower end of the screw rod 10, and a transmission belt 13 is connected to the outer side of the pulley 12. The screw rod 10 is provided with two parallel to each other, and the two screw rods 10 are connected by the pulley 12 and the transmission belt 13. Through the coordinated use of the pulley 12 and the transmission belt 13, the two screw rods 10 maintain the same movement frequency, so that the two sliders 14 drive the cross plate 15 to lift smoothly, and the outer side of the screw rod 10 is threadedly connected to the slider 14, and the slider 14 is away from A cross plate 15 is welded to one end of the screw rod 10, and the cross plate 15 forms a sliding structure with the side frame 8 through the slider 14 and the slide groove 9, and the lower end of the vertical rod 4 passes through the middle of the cross plate 15 through a bearing and is connected to the output end of the rotating motor 7, and the vertical rod 4 is perpendicular to the cross plate 15, and the cross plate 15 is rotatably connected to the vertical rod 4.
