[0007] Wherein, at least two pressure plates for preventing paper from jumping up are arranged on the stop bar, one end of the pressure plate is fixed on the stop bar, and the other end of the pressure plate maintains a gap with the upper surface of the rectangular lower cover plate.

[0008] Wherein, the lower surface of the free end of the pressing plate is also provided with a convex point for pressing the paper.

[0009] Wherein, a pressure plate avoidance groove corresponding to the pressure plate is provided on the lower surface of the rectangular upper cover plate.

[0010] Wherein, the free ends of the rectangular upper cover plate and the rectangular lower cover plate are respectively provided with a dial plate.

[0011] Wherein, the edges of the rectangular upper cover plate and / or the rectangular lower cover plate are provided with hanging rings for hanging the punching machine.

[0012] Wherein, the upper surface of the rectangular lower cover is provided with a paper specification ruler.

[0013] Wherein, a chip box cover is disposed at the bottom of the rectangular lower cover plate, and the chip box cover and the rectangular lower cover plate form a paper scrap storage compartment.

[0014] Wherein, the punching machine includes five of the blade cores.

[0015] The above technical solution can achieve the following beneficial effects: the punching machine in the utility model has a compact structure after being folded, which is more convenient for storage, and the built-in extended positioning column can assist the user in continuous punching, making it more convenient and efficient to use.

[0021] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] like Figure 1-5As shown, the punching machine in this embodiment includes a rectangular upper cover plate 1 and a rectangular lower cover plate 2, and the rectangular upper cover plate 1 and the rectangular lower cover plate 2 are rotatably connected by a rotating shaft 3 arranged on the same side. The lower surface of the rectangular upper cover plate is provided with five knife cores 13, and the upper surface of the rectangular lower cover plate 2 is provided with five blade avoidance holes 23 corresponding to the knife cores 13. The rectangular upper cover plate 1 and the rectangular lower cover plate 2 are also provided with a hook portion 14 and a card slot 26 that cooperate with each other, as shown in FIG. Figure 1 As shown, when the rectangular upper cover plate 1 and the rectangular lower cover plate 2 are closed, a box with a regular structure is formed.

[0024] The side of the blade avoidance hole 23 is provided with an extension positioning post 28 of the same size as the blade avoidance hole 23. After the first punching is completed, the hole at the end is moved to the extension positioning post 28 and is placed on the extension positioning post 28, and the remaining part of the paper can be extended and punched (see Figure 4 ).

[0025] The upper surface of the rectangular lower cover 2 is provided with a stop bar 21 for positioning the edge of the paper to be punched. The stop bar 21 is provided with two pressure plates 22 for preventing the paper from jumping up. One end of the pressure plate 22 is fixed on the stop bar 21, and the other end of the pressure plate 22 maintains a gap with the upper surface of the rectangular lower cover 2, so that the edge of the paper can be smoothly inserted under the pressure plate 22 from the gap. A convex point 221 is also provided on the lower surface of the free end of the pressure plate 22 to further press the paper, thereby preventing the edge of the paper 100 from bouncing up due to the downward pressure of the knife core 13 during the punching process. Correspondingly, the lower surface of the rectangular upper cover 1 is provided with a pressure plate avoidance groove 12 corresponding to the pressure plate 22, thereby ensuring that the rectangular upper cover 1 and the rectangular lower cover 2 can be closed smoothly.

[0026] For ease of use, the free ends of the rectangular upper cover plate 1 and the rectangular lower cover plate 2 are provided with paddles 11 and 24, respectively. In addition, the edge of the rectangular upper cover plate 1 is provided with a hanging ring 4 for hanging the punch. A paper size scale 25 is provided on the upper surface of the rectangular lower cover plate 1, and a chip box cover 27 is provided on the bottom axis of the rectangular lower cover plate 2, and the chip box cover 27 and the rectangular lower cover plate 2 form a paper scrap storage compartment.

[0027] After use, the punching machine can be stored by simply aligning the rectangular upper cover 1 and the rectangular lower cover 2.

[0028] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
