[0030] Furthermore, the quick-release assembly 5 is composed of a connecting block 7, a moving block 8, a fixed rod 9, a sleeve 10, a moving groove 11 and a limiting groove 12 and a compression spring 13. Multiple groups of connecting blocks 7 are slidably connected to the inside of the connecting frame 2 and are located on the outside of the filter 4. The moving block 8 is located at one end of the connecting block 7 extending to the inside of the connecting frame 2. The fixed rod 9 is fixedly connected to the end of the moving block 8 away from the connecting block 7. The sleeve 10 is located on the outside of the connecting block 7. Multiple groups of moving grooves 11 are opened on the outside of the sleeve 10. The limiting groove 12 is opened inside the moving groove 11. The compression spring 13 is sleeved on the outside of the fixed rod 9. When the filter 4 needs to be disassembled, the filter 4 can be easily disassembled through the quick-release assembly 5, so that the filter 4 can be easily cleaned and maintained.

[0031] Among them, a limit block 14 is provided on the outside of the connecting block 7 and extends to the inside of the movable groove 11. The external structure size of the limit block 14 is designed to correspond to the internal structure size of the movable groove 11, and the limit block 14 is connected to the limit groove 12 through the movable groove 11. The limit block 14 is connected to the movable groove 11. When the limit block 14 is displaced inside the movable groove 11, the support block 15 can be displaced to the inside of the limit groove 12.

[0032] Secondly, a plurality of support blocks 15 are provided at one end of the moving block 8 close to the limit block 14, and the moving block 8 is connected to the limit groove 12 through the support blocks 15, so that the support blocks 15 are in contact with the limit block 14. When the limit block 14 moves, the support blocks 15 are driven to move, so that the support blocks 15 can move to the inside of the limit groove 12.

[0033] Furthermore, a fixed block 16 is fixedly connected inside the connecting frame 2 and located on the outside of the fixed rod 9. A through groove is opened inside the fixed block 16. The internal structure size of the through groove is designed to correspond to the external structure size of the fixed rod 9. The fixed rod 9 is connected to the compression spring 13 through the fixed block 16 and the movable block 8. The fixed block 16 is installed on the outside of the fixed rod 9 so that the fixed rod 9 can contact the compression spring 13 through the fixed block 16 and the movable block 8. When the compression spring 13 drives the movable block 8 to move, the fixed rod 9 can move.

[0034] Furthermore, a plurality of groups of snap-in grooves are provided inside the filter screen 4, and the internal structure size of the snap-in grooves is designed to correspond to the external structure size of the fixing rod 9. The filter screen 4 is connected to the fixing rod 9 through the snap-in grooves. When the filter screen 4 needs to be disassembled, the connecting block 7 is pressed to move the supporting block 15 out of the inner position of the limiting groove 12. The arc-shaped structure design of the limiting groove 12 enables the moving block 8 to rotate, so that the supporting block 15 can be moved to the inner position of the moving groove 11. At this time, the outer side of the connecting block 7 drives the moving block 8 to move, squeezes the compression spring 13, and the compression spring 13 is subjected to a force to generate a rebound force, which drives the moving block 8 to move, drives the supporting block 15 to move, so that the supporting block 15 can drive the limiting block 14 to move, and limit it in the inner position of the moving groove 11, so that The fixing rod 9 can be moved out from the inside of the snap-fit ​​groove, so that the filter 4 can be disassembled, which is convenient for cleaning and maintenance of the filter 4. When the filter 4 needs to be installed, the filter 4 is installed inside the connecting frame 2, and the connecting block 7 is pressed to drive the moving block 8 to move, so that the fixing rod 9 can be moved to the inside of the snap-fit ​​groove. At the same time, the displacement of the moving block 8 can drive the limiting block 14 to move, so that the limiting block 14 is moved to the outside of the limiting groove 12. Through the inclined structure of the support block 15, the moving block 8 is rotated, and the support block 15 is moved to the inside of the limiting groove 12. The moving block 8 is driven to move by the compression spring 13, and the support block 15 is limited in the inside of the limiting groove 12, so that the fixing rod 9 can be limited in the inside of the snap-fit ​​groove, and the filter 4 is installed.

[0035] Furthermore, the guide assembly 6 is composed of a connecting tube 17, a fixed column 18 and a spiral sheet 19. The connecting tube 17 is threadedly connected to the bottom of the cooling fan 3, the fixed column 18 is located inside the connecting tube 17, and multiple groups of spiral sheets 19 are located outside the fixed column 18.

The wind contacts the spiral sheet 19, and the wind can be spirally displaced through the spiral sheet 19 to increase the flow rate, thereby better cooling the cutting knife of the paper cutter body 1.

[0036] In this embodiment, the implementation scenario is specifically as follows: in actual use, when the filter screen 4 needs to be disassembled, the connecting block 7 is pressed to move the supporting block 15 out of the inner position of the limiting groove 12. The arc-shaped structure design of the limiting groove 12 allows the moving block 8 to rotate, thereby allowing the supporting block 15 to be moved to the inner position of the moving groove 11. At this time, the outer side of the connecting block 7 drives the moving block 8 to move, squeezing the compression spring 13. The compression spring 13 is subjected to force to generate a rebound force, driving the moving block 8 to move, driving the supporting block 15 to move, so that the supporting block 15 can drive the limiting block 14 to move, and limit it in the inner position of the moving groove 11, so that the fixing rod 9 can be moved out of the inner position of the clamping groove, thereby enabling the filter screen 4 to be disassembled, and the filter screen 4 is convenient for cleaning and maintenance. When the filter screen 4 needs to be installed, the filter screen 4 is installed inside the connecting frame 2, and the connecting block 7 is pressed to drive the The movable block 8 is displaced so that the fixing rod 9 can be displaced to the inside of the card slot. At the same time, the displacement of the movable block 8 can drive the limit block 14 to be displaced, so that the limit block 14 is displaced to the outside of the limit slot 12. The inclined surface structure of the support block 15 makes the movable block 8 rotate, and the support block 15 is displaced to the inside of the limit slot 12. The movable block 8 is driven to be displaced by the compression spring 13, and the support block 15 is limited in the inside of the limit slot 12, so that the fixing rod 9 can be limited in the inside of the card slot, and the filter screen 4 is installed. When the cooling fan 3 is running, the wind force is introduced into the inside of the connecting tube 17, and the wind force contacts the spiral sheet 19. The wind force can be spirally displaced through the spiral sheet 19 to increase the flow rate, so that the cutting knife of the paper cutter body 1 can be better cooled. Compared with the existing heat dissipation device, the utility model can improve the overall practicality of the heat dissipation device through design.
