[0022] When in use, the material to be cut is placed on the upper surface of the machine body 1, and then the motor 2 works to rotate the threaded rod 3 connected to its output end. Since the threaded rod 3 is threadedly connected to the moving block 4 through the thread groove, the moving block 4 can move horizontally when the threaded rod 3 rotates, which makes it convenient to drive the top beam 6 to move horizontally through the moving block 4 to adjust the position of the cutter head 16.

[0023] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the other end of the support rod 5 is fixedly connected to the top beam 6, and a cylinder 7 is provided in the middle of the top end of the top beam 6, the bottom of the cylinder 7 is fixedly connected to the lifting plate 8, and a connecting seat 9 is provided in the middle of the bottom end of the lifting plate 8, a guide rod 10 is vertically installed on one side of the top end of the lifting plate 8, a groove 11 is opened at the bottom of the connecting seat 9, a locking hole 12 is opened on the bottom side wall of the connecting seat 9, one end of the groove 11 is connected to an adapter groove 13, and a slot 14 is distributed on one side of the adapter groove 13, the groove 11, the locking hole 12, the adapter groove 13 and the slot 14 form a snap-fit ​​structure, and the snap-fit ​​structure is provided in the middle of the bottom end of the connecting seat 9, a snap-fit ​​seat 15 is distributed below the connecting seat 9, and a cutter head 16 is provided in the middle of the bottom end of the snap-fit ​​seat 15 , a return spring 17 is fixedly connected to the side wall of the card seat 15, and a locking block 18 is fixedly connected to the other end of the return spring 17, the locking block 18 is slidably connected to the card seat 15 through the return spring 17, and the outer diameter of the locking block 18 is adapted to the inner diameter of the lock hole 12, an auxiliary slide plate 19 is sleeved on the outer side of one end of the locking block 18, an adapter rod 20 is provided in the middle of the top of the card seat 15, and a plug rod 21 is distributed on one side of the adapter rod 20, a collecting chamber 22 is opened on the inner side of the body 1, and a through hole 23 is connected to one side of the top of the collecting chamber 22, an air outlet pipe 24 is provided in the middle of the bottom end of the body 1, and a filter screen 25 is provided on the inner side of the top of the air outlet pipe 24, and an exhaust fan 26 is distributed below the filter screen 25;

[0024] When the cutter head 16 is needed to cut the material, the cylinder 7 will longitudinally push the lifting plate 8 fixedly connected to its bottom, and then the lifting plate 8 will drive the connecting seat 9 fixedly installed at its bottom to adjust its longitudinal position, so as to adjust the height of the cutter head 16, so that it can better contact the material to be cut, and improve the accuracy of subsequent cutting. At the same time, the lifting plate 8 will drive the guide rod 10 to slide along the top beam 6 when it moves longitudinally, so as to improve the stability of the lifting plate 8 during the longitudinal movement. When a lot of waste chips are generated during the cutting process, the exhaust fan 26 will generate suction force, and then the waste chips will be sucked into the inner side of the collection chamber 22 through the through hole 23, so as to facilitate the centralized treatment of the waste chips, and the setting of the filter screen 25 can effectively prevent The waste chips are prevented from entering the inner side of the air outlet pipe 24, so that the waste chips are discharged along with the air outlet pipe 24. When the cutter head 16 needs to be replaced, the card seat 15 is first engaged with the inner side of the groove 11, and then the adapter rod 20 and the plug rod 21 at the top of the card seat 15 are respectively input into the inner side of the adapter groove 13 and the slot 14, thereby realizing the initial stable connection between the card seat 15 and the connecting seat 9. Then, when the card seat 15 is completely input into the inner side of the groove 11, the reverse force generated by the deformation of the reset spring 17 will push the locking block 18 laterally, and then one end of the locking block 18 is input into the inner side of the locking hole 12, thereby further realizing the stable connection between the card seat 15 and the connecting seat 9, which is not only easy to install, but also easy to disassemble later, and has higher practicality.

[0025] Specific working principle:

[0026] The material to be cut is placed on the upper surface of the machine body 1, and then the motor 2 works to rotate the threaded rod 3 connected to its output end. Since the threaded rod 3 is threadedly connected to the moving block 4 through the threaded groove, when the threaded rod 3 rotates, the moving block 4 will move horizontally, which is convenient for the subsequent moving block 4 to drive the top beam 6 to move horizontally to adjust the position of the cutter head 16. When the cutter head 16 is needed to cut the material, the cylinder 7 will work to longitudinally push the lifting plate 8 fixedly connected to its bottom, and then the lifting plate 8 will work to drive the connecting seat 9 fixedly installed at its bottom to adjust its longitudinal position, so as to adjust the height of the position of the cutter head 16, so that it can better contact the material to be cut, thereby improving the accuracy of subsequent cutting. At the same time, when the lifting plate 8 moves longitudinally, it will drive the guide rod 10 to slide along the top beam 6, so as to improve the stability of the lifting plate 8 during the longitudinal movement, and when more When the waste chips are discharged, the exhaust fan 26 works to generate suction force, and then the waste chips are sucked into the inner side of the collecting chamber 22 through the through hole 23, so that the waste chips can be centrally processed. The setting of the filter screen 25 can effectively prevent the waste chips from entering the inner side of the air outlet pipe 24, causing the waste chips to be discharged along the air outlet pipe 24. When the cutter head 16 needs to be replaced, the card seat 15 is firstly engaged with the inner side of the groove 11, and then the adapter rod 20 and the plug rod 21 at the top of the card seat 15 are respectively input into the adapter rod 21. The inner sides of the matching grooves 13 and the slots 14 are connected, thereby realizing a preliminary stable connection between the card seat 15 and the connecting seat 9. Then, when the card seat 15 is completely input into the inner side of the groove 11, the reverse force generated by the deformation of the reset spring 17 will push the locking block 18 laterally, and then one end of the locking block 18 is input into the inner side of the locking hole 12, thereby further realizing a stable connection between the card seat 15 and the connecting seat 9. It is not only easy to install, but also easy to disassemble later, and has higher practicality.
