Therefore, when welding is completed, the arc plate two drives the connecting block to move in the opposite direction, and then drives the bevel bar to move through the connecting block, thereby releasing the limit on the knocking rod. After the limit is released, the knocking rod can rotate through the torsion spring to knock off the welding slag generated by the explosion-proof valve stem during the welding process. At the same time, after the welding is completed, the fixed column moves upward to drive the processing plate to move, thereby lifting the explosion-proof valve stem after the welding is completed, thereby facilitating the staff to take the explosion-proof valve stem, thereby improving the portability of the staff in taking the explosion-proof valve stem and the welding efficiency of the explosion-proof valve stem.

[0010] 3. The explosion-proof valve stem welding device operates through the cooperation among the collection box, the straight plate 1, the rotating rod, the rotating plate, the knocking block, the protrusion, the straight plate 2 and the push plate.
