This design improves the application range of the device and can meet the processing needs of automobile parts of various shapes and welding requirements.

[0033] 5. When the limiting pressing plate is lowered to the lowest point, the triangular block is inserted into the No. 2 vertical groove to push the sliding vertical plate to move transversely, so that the braking state of the side edge rectangular plate is released. At this time, the elastic force of the No. 2 spring will lift the support block and the formed box body upwards, cooperate with the upward movement of the limiting pressing plate, so that the formed box body moves above the base plane, facilitating subsequent welding operation.
