Limiting slide columns 4 are fixedly connected to the left and right sides of the front end of the binding positioning stop 3, which are used for the up-and-down sliding and return of the cutting slide bar 5. Inside between the two limiting slide columns 4, a cutting slide bar 5 is elastically connected by a slide bar and a return spring. The upper and lower ends of the slide bar are fixedly connected to the centers of the inner walls at the upper and lower ends of the limiting slide columns 4, which are used to limit the sliding position of the cutting slide bar 5 and the position of the return spring. The return spring is sleeved outside the slide bar and is located at the lower end of the cutting slide bar 5, which is used for the return of the cutting slide bar 5. Two pressure paper slide bars 6 penetrate up and down inside the left and right sides of the lower end of the cutting slide bar 5, which are used to connect the cutting slide bar 5 and the pressure paper board 7 and adjust the position of the pressure paper board 7. A retaining ring is provided at the upper end of each of the four pressure paper slide bars 6, and all four retaining rings are located at the upper end of the cutting slide bar 5 to prevent the pressure paper slide bars 6 from falling off. The left two pressure paper slide bars 6 and the right two pressure paper slide bars 6 are fixedly connected to a pressure paper board 7 at the lower end, and a positioning hole penetrates up and down through the center of each of the two pressure paper boards 7, which is used for positioning and pressing the paper binding position.

[0023] Preferably, place the paper to be stapled on the upper end of the stapling table 1, and position and align it through three limiting mechanisms 2. At the same time, position the stapling position through the stapling positioning stop block 3. After placing the paper, press down the lever handle 12. The lever handle 12 presses down the cutting slide rod 5 through the transmission roller 13 to slide downward. At this time, the pressure plates 7 on both sides below the cutting slide rod 5 contact the paper first and stop sliding, and press the paper tightly through the paper pressing spring 8 at the upper end. At the same time, position the punching position of the paper through the positioning hole inside the center of the pressure plate 7. The punching sleeve rod 10 continues to move downward under the extrusion of the stapling push rod 9, and passes through the positioning hole to punch the paper rotationally. After punching, release the lever handle 12. The cutting slide rod 5 returns to its original position under the action of the return spring inside the limiting slide column 4. At the same time, the pressure plate 7 returns to its original position under the action of the paper pressing spring 8. The punching sleeve rod 10 ejects the cut paper inside.

[0024] Such as Figure 3 and Figure 4As shown, an internal turning groove 14 is provided at the upper end of the punching sleeve rod 10, and the lower end of the stapling push rod 9 is located inside the turning groove 14 for the up-and-down sliding of the stapling push rod 9 inside the punching sleeve rod 10. Two spiral guide grooves 15 are provided inside the cylindrical inner wall of the turning groove 14, and the two spiral guide grooves 15 are arranged in an up-and-down staggered manner. The lower sides of the left and right ends of the stapling push rod 9 are each internally connected with a turning ball 16 in a rolling manner, and the two turning balls 16 are arranged symmetrically left and right and are respectively connected with the two spiral guide grooves 15 in a rolling manner. The punching sleeve rod 10 can rotate outside the stapling push rod 9 under the guidance of the turning balls 16 and the spiral guide grooves 15. The stapling push rod 9 is connected with the punching sleeve rod 10 through the two spiral guide grooves 15 and the turning balls 16 on both sides, and the stapling push rod 9 can move spirally downward inside the turning groove 14 through the two spiral guide grooves 15 and the two turning balls 16, so that the stapling push rod 9 will not fall off from the inside of the punching sleeve rod 10 and can make the punching sleeve rod 10 rotate through the reaction force. An internal spring expansion groove 17 is provided at the lower end of the stapling push rod 9 for the expansion and contraction of the return spring 18. The return spring 18 is arranged inside the spring expansion groove 17, and the lower end of the return spring 18 is located inside the turning groove 14 and is in contact with the inner wall of the lower end of the turning groove 14, so as to push the stapling push rod 9 at the lowest end back to make the punching sleeve rod 10 return to its original position. A cutting edge is provided at the lower end of the punching sleeve rod 10 for cutting paper. An internal storage hole 19 is provided at the lower end of the punching sleeve rod 10 for storing the cut paper. A waste paper push plate 20 is provided at the lower side inside the storage hole 19 for ejecting the cut paper from the inside of the lower end of the punching sleeve rod 10. The upper end of the waste paper push plate 20 is fixedly connected with a paper ejecting spring 21. The waste paper push plate 20 ejects the cut paper through the paper ejecting spring 21 and returns the waste paper push plate 20 to its original position. The paper ejecting spring 21 is located inside the storage hole 19, and the other end is fixedly connected with the inner wall of the upper end of the storage hole 19 to prevent the waste paper push plate 20 from falling off from the inside of the storage hole 19.

[0025] Preferably, during the process of punching and binding the paper, the punching sleeve rod 10 cuts the paper through the blade at its lower end. When the punching sleeve rod 10 just contacts the paper, the stapling push rod 9 is located at the uppermost side of the steering groove 14. Due to the large resistance when the punching sleeve rod 10 cuts the paper, the stapling push rod 9 can slide downward inside the steering groove 14. During the sliding process of the stapling push rod 9, the steering ball 16 rolls spirally downward inside the spiral guide groove 15. Since the spiral guide groove 15 and the steering ball 16 can limit the relative positions of the stapling push rod 9 and the punching sleeve rod 10, and the position of the stapling push rod 9 is fixed at the lower end of the cutting slide rod 5 and cannot rotate, the punching sleeve rod 10 will rotate outside the stapling push rod 9 under the extrusion of the stapling push rod 9 and the reaction force of the steering ball 16, so that the punching sleeve rod 10 can rotate and cut the paper, and the paper can be cut more labor - saving, thus enabling the punching and binding of the paper to be carried out more quickly, improving the binding efficiency, reducing the binding difficulty. At the same time, the punching sleeve rod 10 receives the cut paper into the receiving hole 19, preventing it from blocking the cutting of the punching sleeve rod 10, and the paper received into the receiving hole 19 will compress the waste paper push plate 20 and the paper - ejecting spring 21 upward, causing the waste paper push plate 20 to slide to the upper side of the receiving hole 19.

[0026] Preferably, after the punching and binding is completed, the punching sleeve rod 10 rotates and slides downward outside the stapling push rod 9 under the action of the return spring 18 and returns to its original position. At the same time, the waste paper push plate 20 slides downward under the action of the paper - ejecting spring 21 and pushes the cut paper at its lower end out of the receiving hole 19, allowing the cut paper to pop out of the lower end inside the punching sleeve rod 10.

[0027] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
