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

[0003] For example, Chinese invention patent publication number CN103373117A discloses a punching and binding machine comprising a frame, a punching mechanism mounted on the frame, a transmission mechanism, and a binding mechanism. The punching mechanism comprises a first punching member having a plurality of first punching blades, a vertically movable baffle, and a second punching member having a plurality of second punching blades, arranged in sequence. The first and second punching members can freely select and punch holes without interfering with each other. The punching and binding machine is equipped with two punching blades, capable of punching two holes per machine, and has a simple structure and is easy to use.

[0004] However, since the device does not have a handle locking function, when the device is in an idle state, the handle of the device will be higher than the frame. When the handle is higher than the frame, the overall height of the punching and binding machine will increase, and the space volume of the entire punching and binding machine will increase, affecting the storage of the entire punching and binding machine. Utility Model Content

[0005] The utility model provides a punching and binding machine that is easy to store. By setting a first limiter and a second limiter, the handle is limited when it is rotated to a position lower than the mounting bracket, thereby reducing the overall height of the punching and binding machine, thereby solving the above-mentioned technical problems.

[0006] The present invention solves the above-mentioned problem by providing a conveniently storable punching and binding machine, comprising a base, a mounting bracket, a punching assembly, and a handle assembly. The handle assembly swings downward to drive the punching assembly downward to punch holes in materials placed on the base. The invention also includes a first stopper movably disposed on the mounting bracket and a second stopper disposed on the handle assembly. The first stopper blocks the second stopper, thereby limiting the handle assembly to a position lower than the mounting bracket, thereby facilitating storage of the punching and binding machine.

[0007] Furthermore, the first limiting member is formed with a blocking end upward, and a horizontal strip hole is also provided on the first limiting member. The first limiting member is horizontally movably mounted on the mounting bracket by setting a limiting bolt at the horizontal strip hole; the first limiting member is horizontally moved to the bottom of the second limiting member to block the handle assembly from resetting and rotating upward, thereby limiting the handle assembly to a position lower than the mounting bracket.

[0008] Furthermore, a toggle adjustment switch is provided on the side of the base, and an adjustment slot is vertically provided on the toggle adjustment switch; the first limit member is also provided with a plug-in end extending downward, and the plug-in end is inserted into the adjustment slot, and the toggle adjustment switch is moved horizontally by being toggled to drive the first limit member to move horizontally.

[0009] Furthermore, the second limiting member includes a rotating disk arranged at the swinging connection end of the handle assembly and a blocking piece arranged at the edge of the rotating disk; when the handle assembly swings to the lowest position range of its stroke, the first limiting member moves to the lower end of the blocking piece to block and limit each other with the blocking piece, thereby locking and limiting the handle assembly.

[0010] Furthermore, at least one movable limit bar is provided on each side of the punching assembly, and mounting brackets are provided on both sides of the punching assembly. At least one limit channel is vertically opened on the mounting bracket, and the length of the limit channel is greater than the length of the movable limit bar. The movable limit bars on both sides of the punching assembly are respectively slidably inserted into the corresponding limit channels, so that the punching assembly is vertically movably arranged between the two mounting brackets.

[0011] Furthermore, the handle assembly includes a handle, a rotating shaft, and a driving gear. The rotating shaft is rotatably set on the mounting bracket, the handle is fixedly connected to the rotating shaft, and the driving gear is also fixedly sleeved on the rotating shaft. The punching assembly is vertically and evenly provided with a plurality of engaging holes that are adapted to the teeth of the driving gear. The handle drives the driving gear to rotate by swinging, and the teeth of the rotating driving gear are inserted into the engaging holes at different heights to push the punching assembly to move up and down.

[0012] Furthermore, the handle is U-shaped, and both ends of the handle are fixedly connected to both ends of the rotating shaft.

[0013] Furthermore, the rotating shaft is also sleeved with a first elastic reset member for driving the rotating shaft to rotate so as to drive the handle assembly to reset and swing upward.

[0014] Furthermore, a second elastic reset member is provided between the mounting bracket and the punching assembly for pulling the punching assembly to reset and move upward.

[0015] Furthermore, it also includes a protective shell arranged on the base and used to accommodate the mounting bracket and the punching component.

[0016] Beneficial effects of the utility model:

[0017] The utility model provides a punching and binding machine that is easy to store. A first limit piece is provided on the side of a mounting bracket and a second limit piece is provided on a rotating shaft. When the handle is rotated to a position lower than the mounting bracket, the first limit piece is moved horizontally below the second limit piece, so that the first limit piece and the second limit piece block each other to limit the handle from swinging upward and returning to its original position, thereby reducing the overall height of the punching and binding machine and providing convenience for storing the punching and binding machine.

[0036] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0037] See also Figures 1 to 8 The utility model is a punching and binding machine that is easy to store, comprising a base 1, a mounting bracket 2, a punching assembly 3, and a handle assembly 4; Figure 2 Taking the direction shown as an example, two mounting brackets 2 are respectively erected on both sides of the right end of the base 1, and the punching assembly 3 is vertically movably connected to the two mounting brackets 2; Figure 4 The handle assembly 4 includes a handle 41, a rotating shaft 42, and a driving gear 43. The rotating shaft 42 is rotatably arranged between the two mounting brackets 2. The punching assembly 3 is located on the left side of the rotating shaft 42. Driving gears 43 are provided at both ends of the rotating shaft 42. A plurality of engaging holes 32 are vertically equidistantly provided on the opposite sides of the punching assembly 3. The plurality of engaging holes 32 can be engaged with the gears of the driving gear 43; correspondingly, when a technician holds the handle 41 and swings the handle 41 downward, the handle 41 will drive the rotating shaft 42 to rotate, and the rotating shaft 42 will drive the driving gear 43 to rotate. When the driving gear 43 rotates, its gear teeth move along a circular path and push the punching assembly 3 to move downward, so as to realize the movement of the punching assembly 3 driven by the handle assembly 4 to bind and punch holes in the material located on the base 1.

[0038] It should be noted that: in this embodiment, when the driving gear 43 rotates driven by the handle 41 and the rotating shaft 42, not all of the multiple gear teeth on the driving gear 43 are in transmission connection with the corresponding meshing holes 32. In fact, only a few of the gear teeth are inserted into a few meshing holes 32, and when these gear teeth are about to separate from the meshing holes 32 during the rotation process, several other gear teeth will be inserted into other meshing holes 32, so that the driving gear 43 and the punching assembly 3 always maintain a transmission connection relationship, ensuring that the driving gear 43 can stably drive the punching assembly 3 to move up and down.

[0039] In this embodiment, the handle 41 is U-shaped, and both ends of the handle 41 are fixedly connected to the rotating shaft 42 .

[0040] Further, see Figure 4 In this embodiment, a first elastic return member 44 is also sleeved on the rotating shaft 42, and the first elastic return member 44 is a return torsion spring in this embodiment; one end of the first elastic return member 44 is fixed to the handle 41, and the other end is fixed to the protective shell or the mounting bracket 2, and when the first elastic return member 44 is in a natural state, the angle between the handle 41 and the base 1 is the largest; when the handle 41 swings downward to drive the punching assembly 3 to move downward, the first elastic return member 44 enters an elastic compression state. At this time, if the handle 41 is released, the first elastic return member 44 can use its own elastic force to drive the punching assembly 3 to automatically move upward and reset. At this time, the handle 41 will also automatically swing upward and reset, providing convenience for the user to use the device again.

[0041] In addition, a second elastic reset member 7 is connected between the punching assembly 3 and the protective shell. The second elastic reset member 7 is a spring. The upper end of the second elastic reset member 7 is fixedly connected to the top of the protective shell, and the lower end is fixedly connected to the punching assembly 3. When the punching assembly 3 moves downward, the second elastic reset member 7 is elastically stretched. When the handle 41 is released, the second elastic reset member 7 elastically retracts to drive the punching assembly 3 to reset and move upward.

[0042] Further, see Figure 2 In this embodiment, a handle 41 shell is provided in the middle of the handle 41 for easy gripping. The handle 41 shell is ergonomically designed to facilitate gripping by the user.

[0043] In this example, see Figure 4The punching assembly 3 includes multiple vertically arranged and parallel punching main boards, and multiple punching ends correspondingly installed at the lower end of each punching main board. The engaging holes 32 are correspondingly opened on the punching main boards. The driving gear 43 pushes the punching main board downward to make the punching end correspondingly open a hole downward, or pushes the punching main board upward to make the punching end withdraw to facilitate material replacement.

[0044] Also, see Figure 5 Two vertically extending limit channels 21 are provided on the two mounting brackets 2, and movable limit bars 31 are integrally provided on the two side edges of the two punching main boards. The vertical length of the limit channel 21 is greater than the vertical length of the movable limit bar 31. The punching assembly 3 extends the movable limit bars 31 on both sides of the two punching main boards into one limit channel 21 respectively, so that the punching assembly 3 is vertically movably connected to the mounting bracket 2, and the punching assembly 3 can be vertically lifted and lowered under the drive of the handle assembly 4 to realize the punching operation.

[0045] Further, see Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 、 Figure 8 , so that the handle 41 can be limited when it is rotated to the lowest position, thereby reducing the overall height of the punching and binding machine, so as to facilitate the storage of the punching and binding machine; in this embodiment, a first limiting member 5 is provided on the outside of the mounting bracket 2, and the first limiting member 5 is a plate member. The first limiting member 5 is formed with a blocking end 51 upward, and a horizontal strip hole 52 is opened in the middle of the first limiting member 5. The lower end of the first limiting member 5 is extended downward to be provided with a plug-in end 53. The first limiting member 5 is horizontally movably installed on the mounting bracket 2 by being provided with a limiting bolt at the horizontal strip hole 52. A toggle adjustment switch 11 is installed on the side of the base 1, and the plug-in end 53 is downwardly inserted into the adjustment slot 12 of the toggle adjustment switch 11; in this regard, the technician can adjust the position of the first limiting member 5 laterally by toggling the toggle adjustment switch 11 laterally.

[0046] At the same time, a second limiting member 6 is also provided on the rotating shaft 42. The second limiting member 6 includes a rotating disk 61 and a baffle 62 provided at the edge of the rotating disk 61. The baffle 62 is an arc-shaped strip plate, and a structural reinforcement portion is also provided at the lower end of the baffle 62.

[0047] In this regard, in this embodiment, when the handle 41 is rotated downward to the lowest position of its swing stroke or rotated to near the lowest position of its swing stroke, the blocking piece 62 will correspondingly rotate to the top of the first limiter 5. At this time, the technician can manually control the first limiter 5 to move horizontally to the bottom of the second limiter 6 by toggling the adjustment switch 11, and make the blocking end 51 just upwardly abut against the structural reinforcement portion of the blocking piece 62, so that the first limiter 5 and the second limiter 6 block each other, thereby limiting the handle 41 to a position lower than the punching assembly 3 and the protective shell, so as to facilitate the storage of the punching and binding machine. Moreover, Figure 3 Taking the direction shown as an example, the technician can also manually control the first limit member 5 to move to the right by toggling the adjustment switch 11, so that the first limit member 5 moves to the right side of the second limit member 6 to unlock the handle 41, so that the handle 41 can be reset and swung upward to the highest position of its stroke, and the punching assembly 3 can also be moved upward to the highest position, so that the punching and binding machine can resume normal operation.

[0048] It should be noted that: For the convenience of understanding of those skilled in the art, Figure 7 The dotted line in the figure only serves to distinguish the rotating disk 61 from the baffle 62 . In actual application, the rotating disk 61 and the baffle 62 are integrally formed and manufactured, and there is actually no structural dividing line between the two.

[0049] Further, see Figure 1 and Figure 3 ,by Figure 1 Taking the direction shown as an example, the protective shell 8 is covered and arranged on the right side of the base 1, the punching component 3 and the mounting bracket 2 are both located inside the protective shell 8, and a suspended empty area is formed between the left side of the protective shell 8 and the base 1 to facilitate the material to extend under the punching component 3.

[0050] It should be noted that, in addition to being used for binding documents, the punching and binding machine of this embodiment also has other uses such as being used as a toy in a handmade market. Therefore, the materials corresponding to the punching and binding machine can be not only paper, but also plastic sheets or thin wood boards or thin sheets or thin boards made of other materials.

[0051] Any matters not mentioned above are applicable to the prior art.

[0052] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; and such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
