[0018] The present invention has the following beneficial effects:

[0019] 1. The present invention cooperates with each other among the components of the moving mechanism, such as the bidirectional motor, the threaded rod and the annular support frame. When it is necessary to weld the pipe, the operator places the required pipe inside the annular support frame, and then starts the bidirectional motor to move the threaded sleeve through the connecting rod to drive the moving plate to slide toward the center of the workbench inside the moving groove, and at the same time drives the annular support frame to drive the pipe to move, so that the two ends of the two pipes are connected. Then the operator turns the adjustment handle to adjust the angle of the welding head of the welder according to the situation of the pipe to ensure that the welding head of the welder can weld the connection of the pipe.

[0020] 2. The present invention uses the mutual cooperation between the components of the rotating mechanism, such as the turntable, the embedding rod and the adjustment plate. During the welding process, the pipe is fixed by the extrusion spring and the adjustment plate. Then, the first motor is started to rotate the turntable counterclockwise. The embedding rod is engaged with the slot and the embedding rod, and the counterclockwise rotation of the embedding rod drives the fixing frame to rotate counterclockwise inside the annular support frame. The pipe is indirectly rotated through multiple slots and embedding rods, thereby making the pipe joints evenly welded. This design achieves the effect of rotating the pipe during the welding process and prevents uneven welding at the pipe joints.

[0021] 3. The present invention cooperates with each other among the second motor, driving gear, brush and other components of the cleaning mechanism. Before welding, the operator can start the second motor to mesh the driving gear with the driven gear so that the driven gear rotates clockwise, driving the brush to rotate clockwise. During the clockwise rotation of the brush, the surface of the pipe is cleaned, and the rust after cleaning falls into the inside of the collection box through the cleaning port. This design achieves the effect of cleaning the pipe, preventing oil and rust from being present on the welded pipe port, thereby affecting the pipe welding effect.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
