By setting the mounting plate 1, the mounting block 2, the mounting groove 3, the support plate 4, the stop block 5, the sliding plate 6, the sliding groove 7, the soft pad 8, the sliding slot 9, the card slot 10, the clamping plate 11, the fixing slot 12, the rotating slot 13, the threaded rod 14 and the turning handle 15, a better use effect is achieved. During use, when it is necessary to adjust the position of the blade 23, the sliding plate 6 can be pinched and pulled backward, so that the sliding plate 6 slides on the top of the support plate 4 through the sliding groove 7. When the sliding plate 6 slides to the required position, the soft pad 8 can firmly clamp the sliding plate 6 at the top of the support plate 4, thus avoiding the situation that the existing paper cutting device has poor cutting effect when facing different requirements during use due to the design of the adjustment structure. The sliding plate 6 slides on the surface of the support plate 4 through the sliding groove 7. The sliding plate 6 is slidably connected with the stop block 5. The soft pad 8 is arranged inside the sliding groove 7, and the soft pad 8 is slidably connected with the support plate 4, which is more convenient for the sliding plate 6 and the soft pad 8 to slide, preventing the situation that the sliding plate 6 and the soft pad 8 cannot continue to slide because they are stuck by the support plate 4 during use. The clamping plate 11 slides inside the sliding plate 6 through the card slot 10. The fixing plate 16 is slidably connected with the sliding plate 6, which is more convenient for the clamping plate 11 to slide, avoiding the situation that the clamping plate 11 cannot continue to slide because it is stuck by the sliding plate 6 during use. The threaded rod 14 rotates inside the clamping plate 11 through the fixing slot 12, and the threaded rod 14 rotates inside the sliding plate 6 through the rotating slot 13. The turning handle 15 is rotatably connected with the sliding plate 6, which is more convenient for the threaded rod 14 to rotate, preventing the situation that the threaded rod 14 cannot continue to rotate because it is stuck by the clamping plate 11 or the sliding plate 6 during use. The screw rod 20 rotates inside the fixing plate 16 through the rotating groove 18. The sliding block 21 rotates on the surface of the screw rod 20 through the threaded groove 22. The sliding block 21 is slidably connected with the limiting plate 17. The blade 23 slides inside the sliding plate 6 through the sliding slot 9, which is more convenient for the sliding block 21 to slide, avoiding the situation that the sliding block 21 cannot continue to slide because it is stuck by the limiting plate 17 during use.

[0026] Example Two

[0027] Please refer to Figures 1-3 Figures 5, there is a limit groove 24 inside the fixing plate 16. A rotating rod 25 is arranged inside the limit groove 24. A rotating roller 26 is installed in the middle of the rotating rod 25 to better press the paper. During use, the paper will slide inward between the sliding plate 6 and the rotating roller 26. At this time, the rotating roller 26 rotates in the middle of the fixing plate 16 through the rotating rod 25 and the limit groove 24. When the paper slides to the required position, it can stop. At this time, the rotating roller 26 firmly presses the paper on the top of the sliding plate 6, thereby preventing the paper from shifting during use. The limit grooves 24 are symmetrically distributed at the front and rear ends of the side surface of the fixing plate 16. The rotating rod 25 rotates inside the fixing plate 16 through the limit groove 24. The rotating roller 26 is rotatably connected to the fixing plate 16, which is more convenient for the rotating rod 25 to rotate and avoids the situation where the rotating rod 25 is stuck by the fixing plate 16 during use and cannot rotate continuously.

[0028] Working principle: When in use, first place the mounting plate 1 in the required position and use bolts to fix the mounting plate 1 firmly through the mounting slots 3 and the mounting blocks 2. Then it can start to be used. During use, when it is necessary to adjust the position of the blade 23, hold the sliding plate 6 and push and pull it to make the sliding plate 6 slide on the top of the support plate 4 through the sliding groove 7. When the sliding plate 6 slides to the required position, it can stop. At this time, the soft pad 8 inside the sliding groove 7 can firmly hold the sliding plate 6 on the top of the support plate 4, and the stop block 5 can prevent the sliding plate 6 from sliding out during the adjustment process. When the blade 23 is adjusted, the paper can be aligned between the rotating roller 26 and the sliding plate 6 and pushed forward. At this time, the rotating roller 26 rotates in the middle of the fixing plate 16 through the rotating rod 25 and the limit groove 24. When the paper is fixed firmly, the motor 19 can be started to drive the screw rod 20 to rotate, so that the screw rod 20 rotates inside the fixing plate 16 through the rotating groove 18. At this time, the screw rod 20 drives the sliding block 21 to slide in the middle of the limiting plate 17 through the thread groove 22 and drives the blade 23 to slide. At this time, the blade 23 slides inside the sliding plate 6 through the sliding groove 9 and cuts the paper. After long-term use, when it is necessary to replace the blade 23, hold the rotating handle 15 and rotate it to make the threaded rod 14 rotate inside the sliding plate 6 through the rotating groove 13. When the threaded rod 14 completely rotates out of the inside of the sliding plate 6 through the rotating groove 13 and out of the inside of the clamping plate 11 through the fixing groove 12, it can stop. Then hold the fixing plate 16 and lift it upward to make the clamping plate 11 slide upward inside the sliding plate 6 through the clamping groove 10. When the clamping plate 11 completely slides out of the inside of the sliding plate 6 through the clamping groove 10, the blade 23 can be replaced.

[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
