[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figures 1 to 6 The present invention provides a technical solution: an automatic adjustment mechanism for a paper cutter, comprising a knife seat 1 and a paper cutter body 19. The interior of the knife seat 1 is provided with a mounting cavity 2, and a threaded rod 3 is rotatably installed inside the mounting cavity 2. The outer side of the threaded rod 3 is threadedly installed with a knife holder 4. The interior of the knife holder 4 is provided with a hole that cooperates with the threaded rod 3, and the knife holder 4 is slidably connected with the interior of the mounting cavity 2. One end of the threaded rod 3 extends to the outside of the knife seat 1 and is fixedly installed with a driven gear 5. A servo motor 6 is fixedly installed on one side of the knife seat 1, and a driving gear 7 is fixedly installed on the output end of the servo motor 6. Two guide rods 8 are fixedly installed on both sides of the knife holder 4, and the guide rods 8 are slidably connected to the inner wall of the knife seat 1. The interior of both sides of the knife seat 1 is provided with holes that cooperate with the guide rods 8. A knife 9 is installed at the bottom of the knife holder 4, and a knife handle 10 is fixedly installed on the top of the knife 9. A mounting groove 11 is provided inside the bottom of the knife holder 4, and the knife handle 10 cooperates with the mounting groove 11. By installing the guide rod 8, the stability of the knife holder 4 and the knife 9 after adjusting the position can be improved.

[0023] Slide grooves 12 are provided inside the tool holder 4 and on both sides of the mounting groove 11. A slide rod 13 is slidably installed inside the slide groove 12. A slide plate 14 is fixedly installed at one end of the slide rod 13. Two pin rods 15 are fixedly installed on one side of the slide plate 14. Pin holes 16 are provided inside both sides of the tool handle 10. The pin rods 15 cooperate with the pin holes 16. A spring 17 is installed on the outside of the slide rod 13.
