The bottom end of the threaded rod 9 extends to the bottom of the horizontal plate 8 and is rotatably connected to the mounting plate 6. The top of the threaded rod 9 is fixedly connected to a turning handle 10.

[0020] By adopting the above technical solution, by rotating the handle 10, the threaded rod 9 is driven to rotate at the same time, thereby driving the mounting plate 6 to move vertically, adjusting the distance between the traction wheel 1 2 and the traction wheel 2 7, and limiting the metal pipes of different diameters.
