The limiting assembly 3 consists of two fixed blocks 31 and a limiting rod 32. The two fixed blocks 31 are respectively fixedly connected to two corners of the bottom of the support plate 13, and the two ends of the limiting rod 32 are respectively fixedly connected to one side of the two fixed blocks 31. One end of the movable plate 25 is movably sleeved on the outer surface of the limiting rod 32, so that the movable plate 25 can be moved. The movable plate 25 is supported so that the movable plate 25 can only slide in a horizontal state at the bottom of the support plate 13. One side of the four movable blocks 22 is respectively fitted with two sides of the two movable plates 25. One side of the two fixed plates 12 is provided with a driving component 4 for driving the two movable plates 25 to slide. The driving component 4 is composed of a forward and reverse motor 41 and a threaded rod 42. The forward and reverse motor 41 is fixedly installed on one side of the fixed plate 12. The forward and reverse motor 41 is electrically connected to an external power supply through an external switch.
