[0026] By adopting the above solution, the installation and disassembly of the cutter 5 can be made simpler and faster by setting through hole 12 and limit bracket 13, which improves the ease of operation and maintenance efficiency of the equipment.

[0027] refer to Figure 4 A motor 15 is fixedly connected to the front side of the receiving groove 7. A screw 14 is fixedly connected to the output end of the motor 15. The rear end of the screw 14 is rotatably connected to the rear side of the receiving groove 7. The guide plates 8 are all threadedly connected to the surface of the screw 14.

[0028] By adopting the above solution, the automatic locking and unlocking of the cutter 5 can be achieved by setting the motor 15 and the screw 14, which greatly simplifies the process of replacing the cutter 5 and improves the safety and efficiency of operation.

[0029] refer to Figure 3A number of support blocks 16 are fixedly connected to both the left and right sides of the connecting plate 4. The positions of the support blocks 16 correspond to the positions of the through holes 12, and the shapes of the tops of the support blocks 16 correspond to the shapes of the bottoms of the limiting frame 13.

[0030] The above solution is adopted: by setting support block 16, it is ensured that the limit frame 13 can slide smoothly along the predetermined path when moving, avoiding deviation or jamming, and ensuring the smoothness and accuracy of the cutter 5 replacement process.

[0031] refer to Figure 1 The frame 2 is fixedly connected to the left and right sides with protective plates 17.

[0034] By adopting the above solution, the operator can easily adjust the position of the extension plate 18 by setting the limit rod 24 and the pull block 26, and the spring 23 automatically resets and locks it securely to prevent accidental movement.

[0035] The working principle of this utility model:

[0036] In use, first pull the pulling block 26 forward, then the pulling block 26 moves the limiting rod 24 forward. Next, use the pulling handle 19 to pull the extension plate 18 upward. When the extension plate 18 reaches its top, release the pulling handle 19. At this time, the spring 23 will reset the limiting rod 24, thus preventing the extension plate 18 from sliding down. After the extension plates 18 on both sides are adjusted, place the material on top of the workbench 1. Then, use the control panel 6 to start the lifting pump 3. The lifting pump 3 drives the cutter 5 downward to cut the material. The cutter 5 needs to be replaced after a period of use. First, use the control panel 6 to start the motor 15. The screw 14 is driven to rotate, which in turn drives the guide plate 8 to move backward. The guide plate 8 then drives the slider 10 to move. Since the slider 10 is slidably connected to the inside of the through groove 11, the slider 10 can only move left and right along the through groove 11. Then the slider 10 will move due to the tilt angle of the guide groove 9. Subsequently, the slider 10 drives the limit frame 13 to move. When the limit frames 13 on both sides move out of the through hole 12, the cutter 5 is released from the locked state. Then the cutter 5 is pulled out from the bottom of the connecting plate 4, and then a new cutter 5 is installed. After installation, the output end of the motor 15 is rotated in the opposite direction, thereby inserting the bottom of the limit frame 13 into the through hole 12, thus fixing the cutter 5.

[0037] In summary, this cutting machine with an easy-to-change cutter, through the coordinated use of a worktable 1, frame 2, lifting pump 3, connecting plate 4, cutter 5, control panel 6, receiving groove 7, guide plate 8, guide groove 9, slider 10, through groove 11, through hole 12, limit frame 13, screw 14, motor 15, support block 16, protective plate 17, extension plate 18, pull handle 19, slide 20, placement block 21, placement groove 22, spring 23, limit rod 24, moving groove 25, and pull block 26, solves the problem that existing equipment often requires manual adjustment of multiple components when changing the cutter, which is complicated and increases the replacement time, operation difficulty, and the possibility of errors. Moreover, in many cases, multiple tools are even required to unlock and reinstall the cutter, further extending downtime and maintenance costs.
