[0026] The driving assembly 7 includes a bidirectional threaded rod 701, both ends of which are rotatably mounted on the side walls of the two groups of mounting plates 6, one end of the bidirectional threaded rod 701 passes through one of the groups of mounting plates 6 and is connected to a driving motor 702, and two groups of moving blocks 703 are symmetrically threadedly connected on the outer wall of the bidirectional threaded rod 701, and the upper surfaces of the two groups of moving blocks 703 are respectively fixedly connected to the lower surfaces of the two groups of positioning seats 501.
