[0020] A positioning assembly is provided on each of the two lifting plates 3. The positioning assembly includes two fixed blocks 8 fixedly mounted on a side wall of the lifting plate 3 close to the upper clamp 7. A bidirectional threaded rod 20 is rotatably connected between the two fixed blocks 8. Two symmetrically arranged positioning blocks 9 are threadedly sleeved on the outer wall of the bidirectional threaded rod 20. A positioning plate 19 located between the two positioning blocks 9 is fixedly mounted on the outer wall of the rotating tube 18.
