[0024] In a specific embodiment, Figures 1 to 4 As shown, the moving assembly 3 includes a motor 301, a roller 302, a rack 303 and a gear 304. The rack 303 is mounted on the bottom surface of the top wing plate of the cross beam 1. The rack 303 meshes with the gear 304. The gear 304 is mounted on one side of the T-slot of the support arm 2.
