[0023] Refer to Figure 1 - Figure 4An electric telescopic rod 11 is installed at one top end of the fixed plate 2. A horizontal plate 12 is installed on the movable end of the electric telescopic rod 11. The horizontal plate 12 moves by the extension and retraction of the electric telescopic rod 11. A fixed block 13 is installed at the top of the fixed plate 2 and close to the electric telescopic rod 11. A rack 14 is installed on the top of the fixed block 13. The outer end of the horizontal plate 12 away from the electric telescopic rod 11 is connected to the outer end of the rack 14. When the electric telescopic rod 11 extends and retracts, the rack 14 moves synchronously on the top of the fixed block 13 through the horizontal plate 12. A limiting groove 1301 is opened on the top of the fixed block 13. A slider 15 is installed inside the limiting groove 1301. The top of the slider 15 is connected to the rack 14.
