The annular rubber sheet 6 can be replaced according to the diameter of the pipe body 17. The annular rubber sheet 6 contacts the inner wall of the pipe body 17 to discharge the debris in the pipe body 17 to the outside, so as to avoid increasing the friction of subsequent traction.

[0025] Four sliding sleeves 7 are fixedly connected to the outer wall of the arc-shaped supporting frame 1, and the inner walls of the two sliding sleeves 7 are slidably connected to the same U-shaped clamp 8.
