Two T-shaped blocks 25 are slidably connected inside the two T-shaped grooves 20. One side of the surfaces of the two T-shaped blocks 25 is fixedly connected with one side of the surface of the cross plate 17. By using the T-shaped blocks 25 to slide inside the T-shaped grooves 20, the stability of the lifting of the cross plate 17 can be improved. Two diagonal braces 24 are symmetrically and fixedly connected between the vertical plate 14 and the bottom plate 1. By arranging the diagonal braces 24, the firmness of the connection between the bottom plate 1 and the vertical plate 14 can be improved.
