The fixing mechanism is used for fixing the framework of the automobile seat, therefore, the fixing mechanism comprises a fixing seat 2 and a clamping jaw 3 arranged in the fixing seat 2, and the clamping jaw 3 is matched with the framework of the automobile seat and used for positioning the framework of the automobile seat in the fixing seat 2. The claw 3 can adopt a claw structure in the prior art, when the framework of the automobile seat is positioned, the bottom surface of the claw 3 is clamped with the framework of the automobile seat, and then the claw 3 is fixed in the fixed seat 2 through a bolt, so that the automobile seat is fixed.

In the present invention, as shown in fig. 3, the welding mechanism includes a welding torch 4 and a holder unit for connecting the welding torch 4, the welding torch 4 is connected to the holder unit by an elevating mechanism, and the welding torch 4 is moved up and down on the holder unit by the elevating mechanism. In addition, a stopper 6 adapted to the trigger 5 of the welding gun 4 is fixedly attached to the elevating mechanism, and the stopper 6 is provided below the trigger 5 of the welding gun 4. During welding, the welding torch 4 first descends along with the elevating mechanism until the welding torch 4 descends to the braking position, and at this time, the trigger 5 of the welding torch 4 is compressed by the stopper 6 and is started, so that the welding torch 4 is in the operating state. After welding, the lifting mechanism drives the welding gun 4 to ascend, so that the trigger 5 is released from being matched with the stop block 6, and the welding gun 5 can be in a non-working state. Since the welding gun 4 of the present invention is in a working state after being lowered, that is, the welding gun 4 is started after approaching the frame of the seat of the automobile, the welding gun 4 of the present invention should be disposed above the fixing base 2 so that the position of the seat frame matches the position of the welding gun 4.
