The end is engraved with threads in the opposite direction. Specifically, the top end of the threaded rod 4 extends to the outside of the bending column 2. Due to the setting of the reverse thread of the threaded rod 4 and the limit of the clamping plate 5 and the rotation groove 3, the threaded rod is rotated. 4. The two clamping plates 5 can be moved closer to or away from the center of the bending column 2 to clamp and position steel pipes of different diameters, which are suitable for bending steel pipes of different diameters; One side is fixedly connected with two fixed rods 6 distributed in parallel, the opposite sides of the two fixed rods 6 are slidably connected with a rotating seat 7, and a first connecting rod 8 is hinged between the clamping plate 5 and the rotating seat 7, A mounting plate 9 is arranged between the two clamping plates 5.
