Further perfecting, the side end of the square hollow frame is fixed with a guide sleeve with a conical outer diameter and a conical inner diameter. The guide sleeve has the function of conveniently installing the steel pipe at the position between the pinch rollers.

The beneficial effects of the utility model are as follows:

1) The steel pipe can be automatically clamped and sent in a reciprocating manner;

2) The problem that the steel pipe is conveyed while rotating can be solved;

3) When the pipe is conveyed, the resistance is small, the energy consumption is small, and the conveying efficiency is high.
