[0028] A bottom hinge seat 2.2 is fixedly installed at the upper end of the bottom support plate near the four corners, and a top hinge seat 2.1 is fixedly installed at the lower end of the top lifting plate near the four corners. The lifting drive mechanism includes two lower first support rods 2.3, two lower second support rods 2.4, two upper first support rods 2.5, two upper second support rods 2.6, two first reinforcement rods 2.10, two second reinforcement rods 2.8, a first reinforcement connecting rod 2.7, a second reinforcement connecting rod 2.16, and a driving mechanism, and the driving mechanism preferably adopts a combined driving mechanism.
