[0032] The driving component 6 drives the two sets of bidirectional screws 4 in the chamber to rotate synchronously, and then drives the two sets of connecting blocks 5 to move toward each other to clamp the materials in the fixed frame 1 and the movable frame 2. Then, the position adjustment component 7 can drive the movable frame 2 to move back and forth on the fixed frame 1, so that the movable frame 2 and the fixed frame 1 can switch between alignment and misalignment, thereby improving the flexibility of welding materials.

[0033] The driving assembly 6 includes a rotating shaft 61 installed in the inner cavity of the chamber through a mounting seat, and driving bevel gears 62 are fixed at both ends of the rotating shaft 61.
