[0025] Working principle of this embodiment: When using the laser welding torch 3, the laser welding torch 3 can be directly taken from the left. After the laser welding torch 3 moves to the left and leaves the top of the trigger plate 6, the pulling force of the tension spring 702 will pull the connecting plate 701 upward, and the connecting plate 701 will drive the fastening plate 703 upward. Then, the user takes out the connecting cable 2 hung on the hanging rack 4 through the laser welding torch 3. Subsequently, through the connection of the connecting cable 2, the laser welding torch 3 can perform operations at a long distance from the welding device body 1. After the operation is completed, the connecting cable 2 is wound around the hanging rack 4 and then the laser welding torch 3 is reset. The reset laser welding torch 3 will push the trigger plate 6 downward, and then push the fastening plate 703 downward to close the exposed gap of the hanging rack 4. At this time, the connecting cable 2 on the hanging rack 4 will not fall off the hanging rack 4. At the same time, the top of the trigger plate 6 pressed downward will contact the laser welding torch 3, which not only restricts the connecting cable 2, but also restricts the laser welding torch 3 in the placing cylinder 5 from slipping out easily, can lock the laser head and restrict the connecting cable 2, and improve the protection effect on both of them.
