[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The second electric push rod drives the U-shaped plate and the driving roller to move until the three driving rollers are against the steel pipe, thereby clamping the steel pipe. At the same time, the steel pipe and the hexagonal cylinder can be coaxially arranged, so that the two steel pipes are coaxial, which can ensure the quality of welding.

[0016] 2. The first electric push rod drives the movable plate to move downward, and the movement of the movable plate drives the baffle plate to move downward. At this time, the baffle plate no longer blocks the steel pipe. At this time, the through slot is opposite to the steel pipe. The first motor is started, and the first motor drives the first screw and the second screw to rotate. Since the thread directions of the first screw and the second screw are opposite, the two sliders can move relative to each other. Finally, the two steel pipes are against each other, and the position of the against is opposite to the welding head, without the need for multiple adjustments.

[0017] 3. The output end of the first electric push rod drives the moving plate to continue to move downward until the welding head contacts the steel pipe, and the welding head welds the steel pipe. The second motor drives the driving rod and the driving roller to rotate, and the driving roller drives the steel pipe to rotate. The welding head can weld the steel pipe around, thus completing the welding work of the steel pipe.

[0018] 4. The moving plate moves downward, driving the elastic rope and the connecting plate downward. At this time, the elastic rope and the airbag are stretched, and air slowly enters the airbag through the intake pipe. In this way, the harmful smoke generated during welding can be sucked into the airbag through the intake pipe. As the elastic rope is stretched, the airbag will be slowly pulled under the resetting effect of the elastic rope, so that the intake pipe can continuously intake air, thereby removing the smoke generated by welding.

[0019] In summary, the three driving rollers of the present invention abut against the steel pipe to clamp the steel pipe. At the same time, the steel pipe and the hexagonal cylinder can be coaxially arranged so that the two steel pipes are coaxial, which can ensure the quality of welding and enable the two sliders to move relative to each other. Finally, the two steel pipes abut against each other, and the abutting position is opposite to the welding head. There is no need for multiple adjustments, which reduces the workload of the staff and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
