In this embodiment, the first half gear 62 and the second half gear 63 have the same size and specifications and are symmetrically arranged. The synchronous belt 64 is wound around the first rotating shaft 621 and the second rotating shaft 631 to drive the first half gear 62 and the second half gear 63 to rotate synchronously. The rack 65 is slidably connected to the carrier plate 61 and is located between the first half gear 62 and the second half gear 63. The upper end of the rack 65 is connected to the upper movable plate 53. The side walls of the rack 65 facing the first half gear 62 and the second half gear 63 are provided with connecting teeth for meshing with the first half gear 62 and the second half gear 63.
