The surface of the rotating rod 7 is evenly fixedly connected with two driving gears 8. When the driven wheel 9 rotates, the rotating rod 7 drives the two driving gears 8 to rotate at a uniform speed on the inner side of the two fixed plates 6. The side of the driving gear 8 is meshed and connected to the linkage gear 5. Under the meshing action of the linkage gear 5 and the driving gear 8, the fixed pipe 4 fixing the welding pipe fitting is synchronously rotated at a uniform speed inside the bearing seat 3, thereby realizing automatic rotation of the welding pipe fitting without manual rotation, greatly improving the welding efficiency, reducing the labor intensity of manual work, and avoiding the phenomenon that the staff's arms are close to the welding point and the sparks generated may cause harm to the staff.

The bearing seats 3 can provide reliable support for the fixed tubes 4 to ensure that they remain stable during rotation without shaking or deflection. A welding head 16 is fixedly installed on the upper end of the main body 1. The output end of the welding head 16 corresponds to the upper end of the processing table 2.
