[0022] The transverse driving mechanism comprises a sleeve 7 fixedly arranged on the outer side of the left end of the lower cross beam 1, both ends of the sleeve 7 are open, a slider 8 is slidably arranged in the sleeve 7 and rotates with the sleeve 7 at the same time, a handle 9 extending upward from the sleeve 7 is connected to the slider 8, and a slide groove 10 is provided on the sleeve 9 to facilitate the sliding of the handle 9, the inner end of the slide groove 10 is open, and the outer end is a closed structure;
[0023] The inner end of the slider 8 is connected to a sliding rod 11, which slides along the middle in sequence through the bottom ends of the hook heads 19 on both sides and the top plate 4 in the middle. The sliding rod 11 rotates and cooperates with the hook heads 19 and the top plate 4 at the same time. The sliding rods 11 on both sides are provided with first limiting flanges 12 that are attached to the side walls of the corresponding hook heads 19. The first limiting flanges 12 are used to push the hook heads 19 to move synchronously when the sliding rods 11 slide.
