[0002] At present, in daily work, it is usually necessary to use binding equipment or punching devices to punch materials and then bind them. Such punching devices are mainly divided into two categories. One is an electric punching device, and the other is a manual punching device. The manual punching device is widely used in the field of office equipment because of its relatively low price, small weight and volume, and flexible and convenient use.

[0003] For example, the Chinese invention patent with the publication number CN103373117A discloses a punching and binding machine, which includes a frame, a punching mechanism, a transmission mechanism and a binding mechanism installed on the frame. The punching mechanism includes a first punching member provided with a plurality of first punching blade knives arranged in sequence, a baffle that can move up and down, and a second punching member provided with a plurality of second punching blade knives. The first punching member and the second punching member can freely select punching without interfering with each other. This punching and binding machine is provided with two types of punching blades, and one machine can punch two hole types, and its structure is simple and easy to use.

[0004] However, when the device is in an idle state, the handle of the device will be in a vertically upward position, and the vertically upward handle will cause the height of the entire punching and binding machine to increase, increasing the space volume of the entire punching and binding machine, which affects the storage and storage of the entire punching and binding machine. Summary of the Utility Model

[0005] The utility model provides a punching and binding machine convenient for storage. By setting a limiting structure, the handle can be rotated to a position close to the base and be limited and fixed, so as to reduce the space volume of the entire punching and binding machine and solve the above technical problems.

[0006] The technical solution for the utility model to solve the above problems is: to provide a punching and binding machine convenient for storage, which includes a base, a mounting bracket, a punching component, and a handle. The mounting bracket is arranged on the base. The punching component is used for punching materials laid on the base. The punching component is vertically movably arranged on the mounting bracket. The handle is swingably arranged on the mounting bracket, and the handle drives the punching component to move downward by swinging downward to punch the materials. It also includes a limiting insert movably arranged on the mounting bracket. A plugging structure for inserting the limiting insert is correspondingly arranged on the punching component. The limiting insert is inserted into the plugging structure to limit the handle at the lowest position of the swinging stroke, so as to facilitate the storage of the punching and binding machine.

[0007] Furthermore, the mounting brackets are arranged on both sides of the base, and each mounting bracket is vertically provided with an activity channel. Corresponding sides of the drilling assembly are provided with activity bars. The vertical length of the activity channel is greater than the vertical length of the activity bars. The drilling assembly is vertically movably mounted on the mounting brackets by inserting the activity bars on its two sides into the two activity channels respectively.

[0008] Furthermore, the plugging structure is a plugging groove or a plugging hole horizontally opened on the activity bar, and the limiting plug strip is horizontally movably mounted on the mounting bracket correspondingly.

[0009] Furthermore, the limiting plug strip includes a main body portion and a locking insertion end. The locking insertion end is fixedly connected to the main body portion and extends horizontally outwards. A horizontal strip-shaped hole is opened on the main body portion, and an anti-dropping threaded part is screwed to the mounting bracket at the horizontal strip-shaped hole to prevent the limiting plug strip from falling. Limiting protrusions for limiting and guiding the horizontal movement of the locking insertion end are also provided on both the upper and lower sides of the locking insertion end.

[0010] Furthermore, it further includes a limiting adjustment button arranged on the side of the base. An adjustment slot is vertically provided on the limiting adjustment button.

Detailed Description of the Embodiment

[0027] In this specification, orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc., which are mentioned or may be mentioned, are defined with respect to the structures shown in the respective drawings. The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component. They are relative concepts and may therefore change accordingly depending on their different positions and usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0028] Please refer to Figures 1 to 7 , a punching and binding machine that is convenient for storage according to a specific embodiment of the present utility model, includes a base 1, a mounting bracket 2, a punching assembly 3, and a handle 4; taking Figure 2 the shown direction as an example, two mounting brackets 2 are respectively arranged on both sides of the right end of the base 1, and both ends of the punching assembly 3 are movably connected to the two mounting brackets 2; the handle 4 is integrally U-shaped, and both ends of the handle 4 are correspondingly fixedly installed on a rotating shaft 17 that is horizontally rotatably arranged between the two mounting brackets 2. A driving gear 18 is provided on the rotating shaft 17, and corresponding meshing holes 19 are vertically and uniformly opened at corresponding positions on the punching assembly 3. The user drives the rotating shaft 17 to rotate around its own axis by swinging the handle 4 around the end where it is connected to the rotating shaft 17, thereby driving the driving gear 18 to rotate. The rotating driving gear 18 pushes the punching assembly 3 to move vertically up and down by making its teeth insert into different meshing holes 19, thereby realizing the punching operation on the material laid on the base 1.

[0029] In addition, a handle shell 20 that is convenient for holding is also provided in the middle of the handle 4. The handle shell 20 adopts an ergonomic design to facilitate the user's holding.

[0030] In this embodiment, the punching assembly 3 includes multiple vertically arranged and parallel punching main boards and multiple punching heads correspondingly installed at the lower ends of each punching main board. The meshing holes 19 are correspondingly opened on the punching main boards. The driving gear 18 correspondingly pushes the punching main board downward to make the punching head correspondingly open downward, or pushes the punching main board upward to make the punching head withdraw to facilitate the replacement of the material.

[0031] Moreover, a vertically extending movable channel 7 is provided on each mounting bracket 2, and movable strips 8 are integrally provided at the two side edges of a punching main board of the punching assembly 3. The vertical length of the movable channel 7 is greater than the vertical length of the movable strips 8. The punching assembly 3 vertically moves up and down correspondingly by making the movable strips 8 on both sides of its punching main board extend into the movable channel 7 and move vertically in the movable channel 7.

[0032] Further, in this embodiment, the movable bar 8 extends into the movable channel 7 and protrudes outward from the mounting bracket 2. A plugging structure 6 is formed on the part of the body of the movable bar 8 that protrudes outward from the mounting bracket 2. A limiting plug strip 5 is horizontally movably arranged corresponding to the outer side wall of the mounting bracket 2. The limiting plug strip 5 is inserted into the plugging structure 6 to limit the handle 4 at a position close to the surface of the base 1, thereby effectively reducing the overall height of the entire punching and binding machine.

[0033] Specifically, the limiting plug strip 5 includes a main body portion 9 and a locking insertion end 10. A horizontal strip-shaped hole 11 is formed on the main body portion 9. An anti-loosening threaded member 12 is inserted into the horizontal strip-shaped hole 11 and screwed onto the mounting bracket 2 to attach the limiting plug strip 5 to the outer side of the mounting bracket 2. The locking insertion end 10 is horizontally arranged. Limiting protrusions 13 for limiting and guiding the horizontal movement of the locking insertion end 10 are arranged on both the upper and lower sides of the locking insertion end 10. The gap between the nut of the anti-loosening threaded member 12 and the mounting bracket 2 is also larger than the thickness of the limiting plug strip 5. The limiting plug strip 5 can only move horizontally under the combined limiting action of the limiting protrusions 13 and the anti-loosening threaded member 12. Correspondingly, by arranging the limiting plug strip 5 on the right side of the movable channel 7 and aligning the locking insertion end 10 of the limiting plug strip 5 with the lowest position that the plugging structure 6 can move to, when the handle 4 swings downward to drive the plugging structure 6 to move to the lowest position, the limiting plug strip 5 can correspondingly move horizontally to be inserted into the plugging structure 6 to fixedly limit the upward reset movement of the punching assembly 3, and finally the handle 4 is also limited to the position closest to the base 1 to fold the entire punching and binding machine.

[0034] In this embodiment, the plugging structure 6 is a plugging groove formed on the movable bar 8, and openings are also formed on both sides of the plugging groove extending to the movable bar 8. In other embodiments, the plugging structure 6 can also be set as a plugging hole or other similar limiting structures that can be adapted to the plug strip.

[0035] Further, to facilitate the horizontal pushing of the limiting plug strip 5, an adjusting insertion end 16 extends vertically downward at the lower end of the main body portion 9. A limiting adjusting button 14 is horizontally movably installed on the side of the base 1. The adjusting insertion end 16 is correspondingly inserted into an adjusting slot 15 inside the limiting adjusting button 14. Correspondingly, the user can push the limiting adjusting button 14 by hand to push the adjusting insertion end 16 and the entire limiting plug strip 5 to move horizontally, so that the locking insertion end 10 correspondingly moves horizontally to be inserted into the plugging structure 6 to lock the handle 4, or the locking insertion end 10 is separated from the plugging structure 6 to unlock the handle 4.

[0036] In addition, a return torsion spring 21 is also sleeved on the rotating shaft 17. One end of the return torsion spring 21 is connected to the handle 4, and the other end is fixed on the base 1 or the mounting bracket 2. When the handle 4 swings downward, the return torsion spring 21 is compressed. When the return torsion spring 21 elastically returns to its original position, the handle 4 swings upward accordingly. Moreover, a return spring 22 is connected and arranged between the mounting bracket 2 and the punching main board. When the punching main board moves downward, the return spring 22 is stretched to generate an elastic force. When the return spring 22 retracts during reset, it can correspondingly pull the punching main board upward, so as to facilitate the repeated use of the punching and binding machine in this embodiment.

[0037] Furthermore, a protective shell 23 is also arranged on the base 1. The protective shell 23 is arranged to cover the right side of the base 1. The punching assembly 3 and the mounting bracket 2 are both located inside the protective shell 23. A suspended empty area is also formed between the left side of the protective shell 23 and the base 1, so as to facilitate the material to extend under the punching assembly 3.

[0038] It should be noted that the punching and binding machine in this embodiment can be used not only for binding documents, but also for other purposes such as toys in the handicraft market. Therefore, the materials to be punched and bound by this punching and binding machine can be not only paper, but also plastic sheets, thin wooden boards or thin sheets or thin boards made of other materials.

[0039] For those not mentioned above, the prior art is applicable.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
