[0030] The working principle of the utility model:

[0031] When the laser nozzle 303 needs to be replaced, the knob 404 is rotated, and the rotating knob 404 drives the adjusting screw rod 401 to rotate in the rotating hole 406 on the two connecting seats 400, avoiding the deviation of the adjusting screw rod 401 during rotation. When the adjusting screw rod 401 rotates, it drives the bevel gear 403 to rotate, and the rotating bevel gear 403 drives the bevel gear ring 304 to rotate through the meshing with the bevel gear ring 304. When the bevel gear ring 304 rotates, it rotates on the rotating ring 309 through the annular rotating groove 308, thereby realizing the rotating effect of the bevel gear ring 304 while avoiding the deviation of the bevel gear ring 304. The continuously rotating bevel gear ring 304 is slowly loosened from the outer threaded connecting ring 302 through the cooperation with the threaded hole 310.

Finally, the outer threaded connecting ring 302 is loosened from the bevel gear ring 304. At this time, pulling the laser nozzle 303 can pull it out, and the adjusting screw rod 401 drives the adjusting plate 402 to move vertically during rotation through the cooperation with the adjusting screw hole 405. The vertically moving adjusting plate 402 slides in the sliding hole 407 on the adapter box 200, thereby limiting the moving direction of the adjusting plate 402. The continuously moving adjusting plate 402 drives the sealing baffle 203 to slide in the movable slot 202 on the adapter box 200. During the process, the sliding sealing baffle 203 slides on the two positioning guide rods 205 through the two guide sliding grooves 204, thereby avoiding the deviation of the sealing baffle 203. The continuously moving sealing baffle 203 moves to the side of the communication hole 201 and blocks the communication hole 201, preventing dust from entering the laser welding gun 100, thereby blocking the extension pipe 101 while disassembling the laser nozzle 303, realizing the dustproof effect. When reinstalling the laser nozzle 303, insert the positioning spout 301 on the laser nozzle 303 into the fixed pipe 300, so that the positioning clamping groove 307 on the positioning spout 301 is aligned with the two positioning blocks 306 in the fixed pipe 300. Until the outer threaded connecting ring 302 is inserted into the threaded hole 310 on the bevel gear ring 304. At this time, press the laser nozzle 303 towards the adapter box 200 while rotating the knob 404 in the opposite direction, so that the sealing baffle 203 moves in the opposite direction and resets, and the communication hole 201 is opened, and the bevel gear ring 304 is reversely rotated and rethreaded onto the outer threaded connecting ring 302, completing the replacement of the laser nozzle 303.
