[0015] The technical solution of the present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0016] Example:

[0017] This embodiment is a paper puncher, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a shell 2 arranged on the base, a gap for paper to be placed between the base 1 and the front of the shell 2, a pressing plate 3 sliding in the vertical direction is provided in the shell 1, and a plurality of punching mechanisms sliding in the horizontal direction are provided on the pressing plate 3, a plurality of blocks sliding in the horizontal direction are provided in the base 1, and the blocks correspond to the punching mechanisms one by one, a groove 5 is provided on the back of the base 1 and the shell 2, a vertical plate 4 is slidably provided on the groove 5, and connecting rods extend from the vertical plate and are respectively connected to the corresponding blocks and punching mechanisms.

[0018] like Figure 3As shown, the housing includes a first plate 14 and a panel mounted on the first plate 14. The first plate 14 and the base are provided with slots for the punching mechanism to slide. The pressing plate 3 is placed in the panel, and both ends of the pressing plate 3 are connected to the first plate 14 via a first spring 6. The punching mechanism includes a slider 7, a cutter head 10, and a pressure block 11. The slider 7 is slidably mounted on the pressing plate 3. A locking nut 8 is provided on the slider 7. The cutter head 10 is fixedly mounted at the lower end of the slider 7. The lower end of the slider 7 is connected to the pressure block 10 via a second spring 9. A first through hole is provided in the middle of the pressure block 10, and the cutter head 10 extends into the first through hole. The slider 7 is fixed to the connecting rod at the upper end of the vertical plate 4, and the pressure block 10 is slidably connected to the connecting rod in the middle of the vertical plate 4. That is, when the vertical plate moves horizontally, it can drive the entire punching mechanism to move horizontally, and when the pressing plate is pressed downward, the slider can move vertically relative to the connecting rod in the middle of the vertical plate. The front inner wall of the base is provided with a guide rail 13, and the stop block 12 is slidably arranged on the guide rail 13. The stop block 12 is fixed to the connecting rod at the lower end of the vertical plate, and a second through hole is provided in the middle of the stop block for the blade to pass through. In this embodiment, the vertical plate and its upper, middle and lower connecting rods are E-shaped.

[0019] When the paper puncher in this embodiment is in use, the spacing of each punching mechanism on the pressing plate is adjusted by translating the vertical plate according to the required hole spacing. When the vertical plate is translated, the vertical plate will drive the punching mechanism and the stop block to translate together. After adjusting the spacing, the punching mechanism is locked and fixed by the locking nut. Then, the paper to be punched is placed in the gap between the base and the shell, and the two ends of the pressing plate are pressed down by hand. When the pressing plate moves downward, the pressing plate drives the slider to move downward, and the slider drives the cutter head and the pressing block to move downward. The pressing block contacts the paper before the cutter head and presses the paper onto the stop block. Then the cutter head contacts the paper to punch holes. Finally, the pressing plate is released and reset under the action of the first spring.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
