By providing the spring piece 18, the concave plate 5 can be pushed, improving the reset speed of the concave plate 5; the front and rear sides of the right side of the concave plate 5 are both hinged to a gear plate 6 through a shaft rod. Tooth plates 7 meshing with the gear plate 6 are fixedly connected to the front and rear sides of the inner wall of the fixed sleeve 4. The front end and the rear end of the right side of the fixed sleeve 4 are both fixedly connected to a rotating rod 8 through a bearing. Circular grooves 19 are opened on the front and rear sides of the left side of the inner wall of the fixed sleeve 4. The left end of the rotating rod 8 is slidably connected inside the circular groove 19. By providing the circular grooves 19, the left end of the rotating rod 8 can be supported, improving the stability of the rotating rod 8 during rotation; a backing plate 9 is fixedly connected to the left side of the top of the rotating rod 8.

[0035] Working principle: The user first performs welding treatment on the shell sheet metal part through the laser welding device 1 and the welding head 3. After the welding is completed, the concave plate 5 is pushed to the right. The concave plate 5 drives the gear plate 6 to move. Since the gear plate 6 meshes with the toothed plate 7, the gear plate 6 will rotate when moving. The gear plate 6 pushes the backing plate 9. The backing plate 9 drives the rotating rod 8 and the pressing plate 11 to rotate. At the same time, the backing plate 9 will stretch the elastic band 10. Then the connecting wire 2 is wound around the surface of the support plate 12. Then the concave plate 5 is released. The elastic band 10 drives the backing plate 9 to reset. The backing plate 9 drives the gear plate 6 to reverse and reset. At the same time, the backing plate 9 drives the pressing plate 11 through the rotating rod 8 to press and fix the connecting wire 2, so as to achieve the effect of conveniently fixing the cable.
