The damaged laser welding gun lens 204 will correspond to the disassembly port 300 during the switching process. After that, you only need to pull the L-shaped extrusion plate 305 in the direction of the damaged laser welding gun lens 204. When the L-shaped extrusion plate 305 moves, it will pass through two sliding The holes 307 slide on the two guide rods 303 respectively to prevent the L-shaped extrusion plate 305 from deflecting. The continuously sliding L-shaped extrusion plate 305 will squeeze the two springs 306 by cooperating with the baffle 304.
