[0037] Working principle: When welding a workpiece is required, the L-shaped frame 10 is first fixed to the rotating shaft 9. Then, the cylinder 8 rotatably connected to the rotating shaft 9 is started, which pulls the connecting rod 7 to rotate the L-shaped rotating plate 12 along the outer wall of the T-shaped plate 11. This causes the rotating plate 18 rotatably connected to the L-shaped rotating plate 12 to push the extrusion rod 19 to slide horizontally along the inner side of the limiting block 6.

[0038] After fixing the L-shaped bracket 201 to the U-shaped support block 202, the servo motor 207 is started, which drives the lead screw 203 to slide along the inner side of the U-shaped support block 202 in conjunction with the slider 205, thereby adjusting the U-shaped support block 208. Then, the servo motor 204 is started, which drives the lead screw 209 to rotate, so that the laser welding head 210 fixedly connected to the slider 206 is adjusted to a suitable position for welding the workpiece. Therefore, it has an adjustment effect, thereby improving the accuracy of workpiece welding and making it easier for operators to use.
