The base clamp platform 101 and the backrest clamp platform 201 are arranged in an "L" shape. When the two are arranged in an "L" shape, not only the fit between the two and the automobile seat frame assembly is reflected, but also the relative sliding adjustability between the two is reflected. When the two are arranged in an "L" shape, the practicality of the two and the adjustable clamping ability for different automobile seat frame assemblies are reflected at the same time. The side of the base clamp platform 101 is engraved with a scale line 104, and an iron rod 105 passing through a magnet ring 106 is fixed inside the mounting groove 103.
[0028] The above scheme further has a through hole guide block 107 sliding inside the guide groove 102, and a ball nut 108 is fixed inside the through hole guide block 107, and the ball nut 108 passes through a two-way handwheel ball screw 109 for relative drive adjustment, and the two-way handwheel ball screw 109 extends to one side of the base clamp table 101 for easy rotation adjustment, wherein the above components constitute a rotational relative adjustment structure, and the rotational relative adjustment structure constituted by the above components can effectively change the relative interval distance between the clamp plates 1010 to clamp and fix different models of automobile seat frame assemblies.
[0029] The above scheme further has a clamp plate 1010 fixed on the through hole guide block 107, and a mounting spring 1011 is fixed on one side of the clamp plate 1010, and a contact plate 1012 is fixed on one end of the mounting spring 1011, wherein the above components constitute an elastic adjustment structure, and the elastic adjustment structure constituted by the above components can effectively make the contact plate 1012 and both sides of the automobile seat frame assembly play a fitting contact clamping and prevent the surface of the automobile seat frame assembly from being scratched.

[0032] In the above scheme, when different automobile seat frame assemblies need to be clamped and welded, the operator holds the two-way handwheel ball screw 109 to drive the through-hole guide block 107 to slide relatively and adjust. When the through-hole guide block 107 is subjected to force and slides relatively and adjusts, the clamp plate 1010 is driven to move relatively under force. When the automobile seat frame assembly is placed on the base clamp table 101, the two-way handwheel ball screw 109 is rotated in the opposite direction to make the contact plate 1012 and the two sides of the automobile seat frame assembly close to contact and clamp. The operator uses the grip 202 to push the backrest clamp table 201 to move under force so that the backrest clamp table 201 contacts the backrest of the automobile seat frame assembly. Then, the operator rotates the two-way handwheel ball screw 109 on the backrest clamp table 201 again so that the other contact plate 1012 contacts the two sides of the backrest of the automobile seat frame assembly to contact and clamp the two sides of the backrest of the automobile seat frame assembly.
