Welding fixture based on hardware thin piece

The utility model provides a welding fixture based on a hardware thin part, and belongs to the technical field of hardware welding. The welding clamp based on the hardware thin part comprises a supporting assembly and a clamping assembly, the supporting assembly comprises a supporting base, a first supporting rod and a connecting piece, during use, when the hardware thin part needs to be rotated to weld other attaching seams, two first limiting plates are driven to be away from the clamp through two electric push rods, and the clamping assembly is driven to clamp the other attaching seams; then the two clamps can be rotated, then the hardware thin part is rotated, then a fitting seam needing to be welded faces a welding worker, then two first limiting plates are driven by two electric push rods to move towards the clamps, the first limiting plates are made to limit the clamps again, and then the fitting seam needing to be welded is welded. And then the welding worker can continue to conduct welding, the hardw
