The plurality of exhaust holes 121 are all connected to the air pipe 102. The base plate 101 is fixed to the top of the laser welding equipment. During the welding process, the protective gas in the air pipe 102 is discharged from the exhaust holes 121 to the outside, thereby protecting the welded parts, making the protection more comprehensive, avoiding oxidation, and extending the service life of the welded parts.

[0025] The bottom frame 105 is fixedly connected to the bottom plate 101 and is located below the bottom plate 101. The rotating seat 109 is fixedly connected to the bottom frame 105 and is located on the inner side wall of the bottom frame 105. The first threaded rod 106 is rotatably connected to the rotating seat 109 and is located on one side of the rotating seat 109.

The first soft plate 115 and the second soft plate 116 can protect the side wall of the weldment from damage, reducing unnecessary cost losses. The controller 114 can facilitate the staff to open and close the motor 108, reducing the workload of the staff. Fixing the weldment in this way avoids displacement during welding, effectively reducing damage to the weldment, and ensuring the quality and efficiency of welding.
