[0030] Working principle: rotate the first screw 38, which can push the sliding seat 34 connected with the first bearing 36 and the end of the first screw 38 to slide on the guide rail 35. At this time, the fixed frame 33 fixed on the upper end of the sliding seat 34 and the conical column 31 fixed on the side of the fixed frame 33 slide together. The outer surface of the conical column 31 is in sliding contact with the outer surface of the upper semicone block 32 of the connecting rod 22. Therefore, after the conical column 31 slides, the connecting rod 22 and the center cylinder 23 on the connecting rod 22 can be squeezed to slide along the guide column 21. The height of the outer end of the U-shaped rod 24 is adjusted to facilitate the insertion of the welding gun 11 into the clamp 26.

Then, the second screw 42 is rotated. The second screw 42 is rotatably connected with the T-shaped block 411 fixed on the side of the second rack 410 through the second bearing 412. After the second screw 42 is rotated, the second rack 410 can be pulled to slide in the accommodating seat 12, thereby driving the second gear 49 to rotate.

The first rack 43 on the surface of the hook rod 41 is in meshing connection with the first gear 44. After the first gear 44 rotates, the hook rod 41 can be driven to slide on the accommodating seat 12. When the outer end of the U-shaped rod 24 is located between the hook rod 41 and the accommodating seat 12, the hook rod 41 is driven to slide inward by the second screw 42. The hook of the hook rod 41 can hook the outer end of the U-shaped rod 24 to fix the U-shaped rod 24 and the welding gun 11. The outer end of the U-shaped rod 24 can be located on the left side or the right side of the welding machine body 1, so as to meet the actual different welding requirements.
