[0027] Working principle: the fixed column 2 is fixed on the loading base 1, and the screw rod 3 is threadedly connected with the clamping block 5 sliding on the fixed column 2 while rotating on the fixed column 2. The output shaft of the drive motor 4 is fixedly connected with the screw rod 3. Therefore, starting the drive motor 4 can cause the clamping block 5 to slide, and cooperate with the loading base 1 to clamp the reducer housing to be welded. The support seat 83 for placing the welding gun is set on the support rod 82, and the support rod 82 is set on the slide seat 81 that can slide on the loading base 1.

At this time, the position of the support rod 82 can be adjusted, so that the support seat 83 can reach a suitable supporting height for the welding gun. After loosening the rotating rod 84, under the action of the reset torsion spring 85, the plug block 86 is inserted into the support rod 82 again to lock it. At this time, the welding gun can be used for welding.

After loosening the movable rod 61 and the slider 71, under the joint action of the first spring 63 and the second spring 74, the structures return to the initial locking state.
