[0025] In this embodiment, the pressing plate 2 is pressed downward so that the pressing plate 2 squeezes the top of the punching assembly 6, so that the punching assembly 6 is adjusted by the spring member to drive the punching member to punch the paper at the corresponding position.

[0026] Furthermore, a distance adjusting groove 17 is opened at the inner front end of the base 1, and a distance adjusting plate 7 is arranged inside the distance adjusting groove 17. The left end of the distance adjusting plate 7 slides through the corresponding position wall of the base 1 and extends to the left end of the base 1. A limiting plate 3 is provided at the left end of the base 1, and the limiting plate 3 and the distance adjusting plate 7 are connected to each other.

[0027] In this embodiment, the limit plate 3 is moved to the left to adjust the distance from the limit plate 3 to the middle position of the base 1 so that the distance change is the same as the half-width of the paper. At this time, one side of the paper is attached to the limit plate 3 so that the hole position of the paper is relatively centered when the paper is punched on the base 1 through the punching components 6 on both sides.

[0028] Furthermore, a main control slot 19 is provided at the inner rear end of the base 1 , and an adjustment component is provided inside the main control slot 19 .

[0029] Furthermore, a limiting component is provided inside the distance adjustment slot 17 , and the limiting component is adjusted by the adjusting component so that the limiting plate 3 is adjusted and moved to a position corresponding to the size of the paper.

[0030] Furthermore, the adjustment component includes a distance adjustment button 5, a fixed shaft 10, a pressure rod 11, a movable sleeve 12 and a through slot 18. Several groups of distance adjustment buttons 5 are arranged at the rear end of the main control slot 19. The top of the distance adjustment button 5 slides through the corresponding position wall of the base 1 and extends to the top of the base 1. The interval between two adjacent groups of distance adjustment buttons 5 is adapted to the half-width size of different paper specifications, that is, the interval between the rightmost distance adjustment button 5 and the adjacent group of left distance adjustment buttons 5 is the same as the difference between the half-width size of the smallest specification paper and the half-width size of the higher specification paper. The position corresponding to the distance adjustment button 5 on the base 1 is engraved with a paper specification size mark, and the engraved paper specification size mark gradually decreases from left to right.

[0031] Furthermore, the fixed shaft 10 is arranged on the inner side of the main control groove 19 near the distance adjustment groove 17, and the two ends of the fixed shaft 10 are respectively fixedly mounted on the inner wall surface of the main control groove 19 at the corresponding positions. The movable sleeve 12 is movably mounted on the fixed shaft 10 through a torsion spring. The number and position of the movable sleeves 12 correspond to several groups of distance adjustment buttons 5. Pressure rods 11 are fixedly mounted on both sides of the movable sleeve 12, and the pressure rod 11 on the side of the movable sleeve 12 close to the distance adjustment button 5 extends to the bottom of the distance adjustment button 5.

[0032] Furthermore, through slots 18 are spaced apart in the middle position of the inner side of the base 1, and the through slots 18 are located between the distance adjustment slot 17 and the main control slot 19. The number and position of the through slots 18 correspond to the groups of distance adjustment buttons 5, and the distance adjustment slot 17 and the main control slot 19 are connected to each other through the through slots 18. The pressure rod 11 on the side of the movable sleeve 12 close to the distance adjustment slot 17 extends to the upper position of the distance adjustment plate 7 through the through slots 18.

[0033] In this embodiment, by pressing the distance adjustment button 5 corresponding to the specified specification, the pressure rod 11 inside the corresponding distance adjustment slot 17 will drive the limit assembly to adjust, so that the limit plate 3 moves the distance corresponding to the specified specification through the adjustment of the limit assembly.

[0034] Furthermore, the limiting assembly includes a distance adjusting spring 8, a limiting card plate 9, an adjusting groove 14, a connecting block 15 and a rear stop 16. The rear stop 16 is fixedly installed on the end of the distance adjusting plate 7 away from the limiting plate 3. The distance adjusting spring 8 is installed at intervals on the side of the rear stop 16 away from the distance adjusting plate 7. The end of the distance adjusting spring 8 away from the rear stop 16 and the wall surface at the corresponding position inside the distance adjusting groove 17 are connected to each other.

[0035] Furthermore, a limiting card plate 9 is provided on the distance-adjusting plate 7 at a position corresponding to the pressure rod 11. The limiting card plate 9 is a "U"-shaped card block. The inner side size of the limiting card plate 9 is adapted to the distance-adjusting plate 7. The limiting card plate 9 is buckled on the distance-adjusting plate 7 without being affected by external force. A connecting block 15 is fixedly installed at the top middle position of the limiting card plate 9. An adjusting groove 14 is provided on the pressure rod 11 at a position corresponding to the limiting card plate 9, and the connecting block 15 is buckled on the adjusting groove 14, and the connecting block 15 can move in the adjusting groove 14 on the pressure rod 11.

[0036] In this embodiment, when the pressure rod 11 is lifted inside the distance adjusting slot 17 when the distance adjusting button 5 is pressed, the pressure rod 11 will drive the limit card plate 9 to rise inside the distance adjusting slot 17 through the adjusting slot 14 and the connecting block 15, so that the limit card plate 9 moves out of the blocking area of ​​the rear stop block 16, so that the distance adjusting plate 7 will drive the limit plate 3 to move elastically through the distance adjusting spring 8 until it is blocked by the next group of limit card plates 9, thereby completing the rapid adjustment operation of the distance of the specified specification.

[0037] In this embodiment, the side wall limits on both sides of the distance adjustment groove 17 and the connecting block 15 can be moved on the adjustment groove 14, so that the limit card plate 9 can always remain perpendicular to the distance adjustment plate 7 when rising or falling, thereby effectively completing the carding of the distance adjustment plate 7 and the blocking of the rear block 16.

[0038] Furthermore, an auxiliary pressure plate 13 is fixedly mounted on the compression rod 11 , and the auxiliary pressure plate 13 extends away from one end of the compression rod 11 to above an adjacent group of right compression rods 11 .

[0039] In this embodiment, the auxiliary pressure plate 13 on the left pressure rod 11 presses on the right pressure rod 11, so that when the right (small specification) distance adjustment button 5 is pressed, the pressure rod 11 will not drive the left pressure rod 11 to be pressed through the auxiliary pressure plate 13. When the left (large specification) distance adjustment button 5 is pressed, the pressure rod 11 will drive the right pressure rod 11 to be pressed through the auxiliary pressure plate 13. In summary, when the distance adjustment button 5 corresponding to the specified specification is pressed, all the distance adjustment buttons 5 on the right side will be pressed down synchronously with it, so that the pressure rod 11 corresponding to the distance adjustment slot 17 will drive all the corresponding limit card plates 9 to be lifted, so that the rear stopper 16 can be quickly no longer blocked and the distance adjustment plate 7 can be driven to move to the position of the specified specification through the distance adjustment spring 8, thereby completing the rapid adjustment of the paper size according to the specification.

[0040] The working principle and use process of this utility model:

[0041] When in use, by pressing the distance adjustment button 5 corresponding to the paper specification that needs to be punched, the distance adjustment button 5 drives the limit card plate 9 in the corresponding position to be lifted through the pressure rod 11 and the auxiliary pressure plate 13, so that the limit card plate 9 moves out of the blocking area of ​​the rear stopper 16, thereby making the distance adjustment plate 7 drive the limit plate 3 to move a specified distance through the distance adjustment spring 8 until the rear stopper 16 is blocked again. At this time, the distance from the right side of the limit plate 3 to the middle position of the limit plate 3 corresponding to the base 1 is half the width of the paper. At this time, put one side of the paper against the right side of the limit plate 3, and When the paper is moved to the position above the base 1 and below the punching assembly 6, the punching assembly 6 punches the designated area of ​​the paper by pressing the pressing plate 2, thereby completing the punching operation. At the same time, when the limit plate 3 needs to be stored, the corresponding distance adjustment button 5 is pressed again, so that the limit card plate 9 inside the distance adjustment slot 17 is lifted, and the limit plate 3 is pushed to drive the distance adjustment plate 7 to move into the distance adjustment slot 17 until the limit plate 3 is stored. Then, the distance adjustment button 5 is released, so that the limit card plate 9 blocks the rear block 16 again, thereby completing the storage.

[0042] In this embodiment, by pressing the distance adjustment button 5 corresponding to the paper specification, the position of the limit plate 3 can be adjusted effectively and quickly, thereby effectively and efficiently improving the adaptation adjustment of the paper specification and effectively avoiding the tedious and inaccurate manual adjustment.

[0043] In this embodiment, the adjustable distance plate 7 is blocked by the limit card plate 9 at the rear stop block 16, so that when performing punching operations or placing paper operations, the limit plate 3 will not move again due to external force impact, thereby effectively ensuring that the limit plate 3 will not be offset when performing continuous punching operations on paper of the same specification, thereby effectively improving the stability during continuous operations.

[0044] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
