[0034] Reference Figure 1 and Figure 3 The clamping assembly 6 includes a clamping plate 62, and the clamping plate 62 is symmetrically distributed in two groups. The clamping surface of the clamping plate 62 is a rubber surface. A hinge rod 63 is hinged at the bottom of the left side of the clamping plate 62, and the hinge rod 63 is symmetrically distributed in two groups. The clamping plate 62 is driven to slide by the moving effect of the hinge rod 63. The left end of the hinge rod 63 is hinged to a hinge block 64, and the hinge block 64 is moved to drive the hinge rod 63 to move. A square groove 61 is opened on the left side of the top of the workbench 1, and the square groove 61 is symmetrically distributed in two groups.

[0035] Reference Figure 2 and Figure 4The outer wall of the rotating rod 56 is rotatably connected to the inner wall of the support frame 2, and the outer wall of the rotating rod 56 is fixedly connected to the outer wall of the laser lens 4. The laser lens 4 is fixedly prevented from falling off. The outer wall of the movable rod 53 is slidably connected to the inner wall of the slide groove 54.

The outer wall of pull rod 575 is slidably connected to the top inner wall of fixed rod 572. The sliding effect of pull rod 575 drives block 574 to slide.

[0038] Reference Figure 4 The outer wall of the block 574 is slidably connected to the top inner wall of the fixing rod 572. Through the sliding effect of the block 574, the block 574 and the slot 576 are engaged or released. The outer wall of the block 574 is engaged with the inner wall of the slot 576. Through the engagement effect of the block 574 and the slot 576, the fixing rod 572 limits the block 571.

[0039] Working principle: When the workpiece needs to be laser cut, the staff places the workpiece between the two sets of clamping plates 62, and starts the electric telescopic rod 65, which drives the hinge rod 63 to move, thereby driving the two sets of clamping plates 62 to slide along the inner wall of the square groove 61 and approach each other, so as to clamp and fix the workpiece.

[0040] When the workpiece is clamped and fixed, the staff pulls the pull rod 575 in the direction away from the block 571, and the pull rod 575 drives the block 574 to release the clamping effect with the clamping groove 576, and at the same time releases the limiting effect on the block 571, and the staff slides the movable rod 53 along the inner wall of the slide groove 54 to drive the connecting rod 52 to move, and at the same time, the connecting rod 52 drives the connecting frame 51 and the rotating rod 56 to rotate, thereby driving the laser lens 4 to rotate and adjust the angle of the laser lens 4. When the adjustment is completed, the staff loosens the pull rod 575, and the elastic force of the spring 573 causes the clamping block 574 to be clamped with the clamping groove 576, and at the same time, the block 571 is limited, so that the block 571 remains fixed, and the staff screws the threaded rod 55 to drive the movable rod 53 to move vertically, thereby fine-tuning the angle of the laser lens 4.

[0041] The staff starts the electric slide rail 3 to drive the support frame 2 to move horizontally, and drives the laser lens 4 to move, and performs laser cutting on the clamped workpiece. When the laser cutting is completed, the staff retracts the electric telescopic rod 65, so that the two sets of hinged rods 63 drive the two sets of clamping plates 62 to slide and move away from each other, making it easier for the staff to take out the workpiece.
