The lifting box 1 continues to be lifted downward so that the pipe is located between the arc-shaped clamping plates 8. At this time, the movable plate 7 is pushed so that the arc-shaped clamping plates 8 clamp the pipe, and the screw rod 25 is rotated. The screw rod 25 moves downward along the path of the threaded hole, and then the screw rod 25 pushes the second connecting plate 23, so that the second connecting plate 23 pushes the limit tooth 24, so that the limit tooth 24 engages with the rack 19 to prevent the movable plate 7 from moving.
