[0013] Preferably, a plurality of threaded holes are formed on the side wall of the extension plate, wherein a screw is movably sleeved on the side wall of one of the bottom plates, and the other end of the screw is threadably sleeved on the inside of the corresponding threaded hole.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model, by setting up multiple driving wheels, multiple driven wheels and double-axis motors, can drive the corresponding two rotating rods to rotate synchronously by starting the double-axis motors. The rotation of the two rotating rods can drive the adjacent rotating rods and the driving wheels to rotate. The two steel pipes are placed between the multiple driving wheels and the multiple driven wheels, so that the synchronous rotation of the two steel pipes can be smoothly realized, the welding speed is accelerated, and the work efficiency is improved.
