Description

Technical Field

[0001] This utility model belongs to the field of paper punching technology, and specifically relates to a punching tool for bills. Background Technology

[0002] In financial management, it is often necessary to punch holes and thread ropes through the organized invoice books to complete the binding for later filing. Commonly used invoice punching tools include push-button punchers and electric punching machines.

[0003] Because different types of tickets vary in material, flat area, and binding thickness, ticket albums with harder materials, larger flat areas, and thicker binding are suitable for large-sized punch needles; ticket albums with softer materials, smaller flat areas, and thinner binding are suitable for small-sized punch needles. However, both push-button type punchers and electric punchers only have one type of fixed-size punch needle, which is not very versatile and cannot meet the punching needs of different sizes. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing punching machines only have one type of punching needle with a fixed size, which has poor applicability and cannot meet the needs of punching holes of different sizes.

[0005] To address the aforementioned technical problems, this utility model discloses a document punching tool, comprising a base supporting the document to be punched, and a support assembly, a punching assembly, and a drive assembly disposed on the base. The support assembly includes a support rod erected on the base and a support seat movably mounted on the support rod in a vertical direction. The punching assembly includes a housing and punching components disposed within the housing. The housing is a hollow housing extending horizontally and rotatably mounted on the support seat. The punching components include a rotating shaft extending horizontally and rotatably mounted within the housing, and multiple sets of punching members evenly spaced horizontally on the rotating shaft. Each punching member in each set is movably mounted on the rotating shaft in a vertical direction, and each set of punching members includes multiple punching heads of different diameters disposed circumferentially along the rotating shaft. The drive assembly includes a first drive component, the output end of which is connected to the housing in a transmission connection, driving the housing to move vertically relative to the base.

[0006] Using the above technical solution, the document to be punched is placed on the base. The support assembly supports the punching assembly on the base, positioning the punching assembly above the document. The drive assembly can drive the punching assembly to move vertically relative to the base, i.e., moving vertically toward the document to be punched. Multiple punching heads of different diameters are arranged circumferentially along the axis of rotation within the housing of the punching assembly. When the housing rotates relative to the support base, it drives the multiple sets of punching components inside to rotate, causing one size of punching head in each set of punching components to face the base. The operator can select the corresponding size punching head to face the base according to the required punching size. The rotation of the punching component's shaft drives the punching member mounted thereon to move vertically, causing the punching head facing the base to move vertically until it extends beyond the housing and faces the document to be punched. The first driving component drives the housing to move the punching component vertically, extending beyond the housing and facing the punching head of the document to be punched, thus performing the punching operation on the document. The document punching tool provided by this utility model can rotate the housing to rotate the punching heads of different diameters of the punching component, thereby switching between punching heads of different diameters. It has a wide range of applications and can meet the punching needs of documents of different sizes. In addition, multiple sets of punching members evenly spaced horizontally on the rotating shaft can simultaneously punch multiple evenly spaced string holes in the area to be punched on the document, thereby improving punching efficiency.

[0007] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a ticket punching tool. Support components are respectively arranged at the left and right ends of the housing in the horizontal direction. The lower end of the support rod of each support component is fixedly connected to the base and extends upward in the vertical direction. The support seat is movably arranged at the upper end of the support rod in the vertical direction. The housing is in the shape of a hollow cylinder and its two ends are rotatably arranged in the mounting holes of the corresponding support seats through a one-way rotation mechanism.

[0008] Using the above technical solution, the support components are located at the left and right ends of the housing. This not only provides punching space for the punching head of the punching component in the middle of the housing, but also provides support for both ends of the housing. Furthermore, both ends of the housing can move synchronously with the corresponding support seats in the vertical direction. A one-way rotation mechanism is provided between both ends of the housing and the mounting holes. On the one hand, the hollow cylindrical housing can rotate within the mounting holes of the support seats to switch the punching head. When a suitable punching head is switched to, the one-way rotation mechanism can lock the housing and the mounting holes, preventing unnecessary relative rotation between the housing and the support seats during punching, which would affect the punching accuracy.

[0009] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a punching tool for bills. The one-way rotation mechanism includes a movable pawl disposed at the end of the housing and a circumferential toothed groove disposed on the inner circumferential wall of the mounting hole of a corresponding support. The circumferential toothed groove is distributed along the circumferential direction of the mounting hole on the inner circumferential wall of the mounting hole. One end of the movable pawl is rotatably connected to the outer circumference of the end of the housing, and the other end is adapted to engage with one of the toothed grooves in the circumferential toothed groove.

[0010] By employing the above technical solution, circumferential toothed grooves are provided on the inner circumferential wall of the mounting hole, and a movable pawl is provided at the end of the housing. When the housing drives the movable pawl to rotate in the direction of the opening of the circumferential toothed groove, the housing can rotate relative to the support base, facilitating the switching of punch heads of different diameters towards the base. When the movable pawl is fitted and engaged with one of the toothed grooves in the circumferential toothed groove, the housing and the inner circumferential wall of the mounting hole are locked together, preventing unnecessary relative rotation between the housing and the support base during punching, which would affect the punching accuracy.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a punching tool for bills. The one-way rotation mechanism includes an elastic locking part disposed at the end of the housing and a circumferential groove disposed on the inner circumferential wall of the mounting hole of a corresponding support. The circumferential grooves are evenly distributed on the inner circumferential wall of the mounting hole along the circumference of the mounting hole. The elastic locking part protrudes from the outer wall of the end of the housing and elastically engages with one of the grooves in the circumferential groove.

[0012] By employing the above technical solution, a circumferential groove is provided on the inner wall of the mounting hole, and an elastic locking part is provided at the end of the housing. When the housing rotates along the opening direction of the circumferential groove, the elastic locking part is compressed back into the housing by the inner wall of the mounting hole, enabling the housing to rotate relative to the support base. This facilitates switching the orientation of punch heads of different diameters towards the base. When the housing rotates to the position where the elastic locking part matches one of the grooves in the circumferential groove, the elastic locking part pops out of the housing, locking the housing against the inner wall of the mounting hole. This prevents unnecessary relative rotation between the housing and the support base during punching, thus avoiding impact on punching accuracy.

[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a punching tool for bills. Each support base has a hollow sleeve portion extending vertically and facing downward at its bottom end. The support rod is formed at least at its upper part as a sleeve rod portion adapted to the hollow sleeve portion. The hollow sleeve portion can be slidably sleeved on the outer periphery of the sleeve rod portion.

[0014] Using the above technical solution, when the bottom end of the hollow sleeve is located at the upper end of the sleeve rod, the punching component and the housing are supported above the base. Through the relative sliding arrangement between the hollow sleeve at the bottom end of the support base and the sleeve rod of the support rod, when the first driving component drives the housing to move vertically towards the base, the housing causes the hollow sleeve of the support base to slide downwards relative to the outer periphery of the sleeve rod. The housing also causes the punching head facing the document to be punched to move downwards to complete the punching.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a ticket punching tool, wherein the support rod is a spring rod, the upper end of the spring rod is fixedly connected to the bottom end of the support base, and the lower end is fixedly connected to the base.

[0016] Using the above technical solution, the spring rod can support the support base, housing and punching component above the base when it is in the initial state. When the first driving component drives the housing to move vertically toward the base, the housing drives the support base to move downward. The housing also drives the punching head toward the document to be punched to move downward to complete the punching. During this process, the bottom end of the support base squeezes the upper end of the spring rod to compress the spring rod.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a punching tool for bills. Each punching component includes a central worm gear and two punching heads respectively disposed at both ends of the central worm gear. A plurality of worm wheels adapted to multiple sets of punching components are sleeved on the rotating shaft. Each set of punching components includes one punching component. Each worm wheel is connected to the central worm gear of the corresponding punching component. Furthermore, a through hole is provided on the housing at a position corresponding to each punching head for the corresponding punching head to pass through.

[0018] Using the above technical solution, a worm gear fitted on the rotating shaft meshes with the central worm for transmission. When the worm gear rotates with the rotating shaft, the rotational motion of the worm gear is converted into linear motion of the central worm in the vertical direction. That is, the two punch heads at both ends of the central worm can move vertically until one punch head extends out of the through hole and the other retracts into the housing. The diameter of the punch head selected according to need controls the rotation of the rotating shaft to be forward or reverse, thereby causing the worm gear to push the central worm to move back and forth in the vertical direction, allowing the punch head of the required size to pass through the through hole. The punch head at the other end of the central worm of this punching component moves into the housing. The housing protects the punch head that has retracted into the housing, preventing the operator from accidentally touching the punch head.

[0019] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a punching tool for bills, wherein in each punching component, a sleeve adapted to the corresponding through hole is sleeved at the end of the punching head near the middle worm gear on each side.

[0020] By adopting the above technical solution, by setting a sleeve that is compatible with the through hole, when the first driving component drives the housing to press down for punching, the outer wall of the sleeve and the inner wall of the through hole can be matched to prevent the punching head from shaking when pressing down.

[0021] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a ticket punching tool, wherein the driving component further includes a rotary motor, and the output end of the rotary motor is connected to the rotating shaft for transmission.

[0022] By adopting the above technical solution, the rotation direction of the rotating shaft around its axis is controlled by the rotating motor, thereby transmitting the rotation to the corresponding punching component, so that the punching head of the required size in the punching component can move vertically to extend out of the shell.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a ticket punching tool, wherein at least one end of the housing is provided with a rotating handle.

[0024] Using the above technical solution, a rotating handle is provided at at least one end of the housing to facilitate rotating the housing to select the punch head of the required size, so that the punch head faces the base.

[0025] The beneficial effects of this utility model are as follows:

[0026] This utility model provides a punching tool for banknotes, including a base for supporting the banknote to be punched, and a support assembly, a punching assembly, and a drive assembly disposed on the base. The banknote to be punched is placed on the base, and the support assembly supports the punching assembly on the base so that the punching assembly is positioned above the banknote. The drive assembly can drive the punching assembly to move vertically relative to the base, i.e., towards the banknote. Multiple punching heads of different diameters are arranged circumferentially along the axis of rotation within the housing of the punching assembly. When the housing rotates relative to the support base, it can drive the multiple sets of punching components inside to rotate, so that one of the punching heads of each punching component in each set faces the base. The operator can select the corresponding size punching head to face the base according to the required punching size. The rotation of the punching component's shaft drives the punching member mounted thereon to move vertically, causing the punching head facing the base to move vertically until it extends beyond the housing and faces the document to be punched. The first driving component drives the housing to move the punching component vertically, extending beyond the housing and facing the punching head of the document to be punched, thus performing the punching operation on the document. The document punching tool provided by this utility model can rotate the housing to rotate the punching heads of different diameters of the punching component, thereby switching between punching heads of different diameters. It has a wide range of applications and can meet the punching needs of documents of different diameters. In addition, multiple sets of punching members evenly spaced horizontally on the rotating shaft can simultaneously punch multiple evenly spaced string holes in the area to be punched on the document, thereby improving punching efficiency.

[0041] To address the problem that existing punching machines only offer one type of fixed-size punching needle, resulting in poor applicability and an inability to meet the punching needs of different sizes, this utility model provides a document punching tool. Firstly, by rotating the housing, the punching components with punching heads of different diameters can be rotated, thus switching between punching heads of varying diameters, making it widely applicable and capable of meeting the punching needs of documents of different diameters. Secondly, it can simultaneously punch multiple evenly spaced string holes in the area to be punched on the document, thereby improving punching efficiency. Firstly, the overall structure of the document punching tool will be described.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] like Figure 1 As shown, the bill punching tool includes a base 1, which is used to hold the bill to be punched. Figures 1-5 (Not shown in the image), the upper surface of the base 1 is typically a smooth and flat plane, facilitating the horizontal placement of the document on this plane and ensuring even force distribution during punching. The document punching tool also includes a support component 2 and a punching component 3 mounted on the base 1. The support component 2 is the basic part of the document punching tool, used to support the punching component 3 on the base 1, positioning the punching component 3 above the document to be punched. The support component 2 may include a support rod 20 erected on the base 1, with a support seat 21 at the upper end of the support rod 20. The support seat 21 and the support rod 20 may be correspondingly mounted at both ends of the punching component 3. The support seat 21 may be a support plate adapted to the bottom shape of the housing 30 of the punching component 3. The specific shape can be arc-shaped or horizontal, depending on the bottom shape of the housing 30. Alternatively, the support seat 21 may be a support block whose upper end is adapted to the outer periphery shape of the end of the punching component 3, as long as it can support both ends of the punching component 3 on the support seat 21.

[0044] The punching assembly 3 is the main part of the document punching tool. The punching assembly 3 includes multiple punching heads 3121 with different diameters, which can be selected according to the punching requirements to punch the document.

[0045] like Figure 1 As shown, the punching assembly 3 specifically includes a housing 30 and a punching component 31 disposed within the housing 30. The housing 30 is mainly used to house the punching component 31. The housing 30 can also drive the punching component 31 to rotate relative to the support base 21, so that the punching head 3121 of the required diameter rotates to be vertically facing the base 1 (i.e., located above the document to be punched, see details). Figure 1 The punch head 3121 is located directly above the base 1 with its head facing downwards. The housing 30 is horizontal ( Figure 1The arrow X in the diagram (the horizontal direction described later is the same as here, and will not be repeated) extends, and its interior is hollow, having a chamber to accommodate other components. To facilitate rotation, the housing 30 can be cylindrical. During downward punching, the housing 30 and the support 21 move synchronously in the vertical direction (…). Figure 1 (The arrow Y in the image, and the vertical direction described later is the same as here, so it will not be repeated) moves downwards, causing the downward-pointing punch head 3121 to penetrate the document to be punched, punch out the rope hole, and return to its original position after punching is completed. Figure 4 and Figure 5 As shown, a rotating handle 33 can be provided at one or both ends of the housing 30 to facilitate the operator's rotation of the housing 30. Alternatively, a motor can be connected to one end of the housing 30 to drive the housing 30 to rotate. Figure 1 and Figure 4 The rotating motor 41 in the middle.

[0046] The punching component 31 is a key part of the punching assembly 3, such as Figure 1 and Figure 2 As shown, the punching component 31 includes a rotating shaft 311 and multiple sets of punching members 312. The axial direction of the rotating shaft 311 is parallel to the length direction of the housing 30. The rotating shaft 311 is arranged horizontally and can rotate around its own axis. The multiple sets of punching members 312 are evenly spaced on the rotating shaft 311 along its axial direction. Each set of punching members 312 can be driven by meshing with the rotating shaft 311. For example, a worm gear 313 can be sleeved on the rotating shaft 311, and the punching member 312 can be configured with a central worm 3122, with punching heads 312 of different diameters connected to both ends of the central worm 3122. 1. The middle worm 3122 is tangent to the outer periphery of the worm wheel 313. The middle worm 3122 and the rotating shaft 311 are driven by the worm wheel 313 sleeved on the rotating shaft 311. When the worm wheel 313 rotates with the rotating shaft 311, the middle worm 3122 is driven to make linear motion, so that the rotational motion of the rotating shaft 311 can be transmitted to the punching component 312 and converted into the linear motion of the punching component 312. This causes the punching component 312 to move vertically downward until the punching head 3121 extends out of the housing 30. Setting multiple sets of punching components 312 can punch multiple rope holes on the document in one punching and pressing process, which is beneficial to improving the punching efficiency.

[0047] like Figure 1As shown, the specific structure of the punching component 31 is as follows: a rotating shaft 311 is disposed inside the housing 30 and extends parallel to the extension direction of the housing 30; multiple sets of punching components 312 are evenly spaced along the horizontal direction on the rotating shaft 311. It should be noted that the rotational movement of the housing 30 relative to the support base 21 when switching the punching head 3121 and the rotational movement of the rotating shaft 311 driving the worm gear 313 do not occur simultaneously; the two rotational movements do not interfere with each other, and each rotational movement has a different purpose. When the housing 30 rotates, the rotating shaft 311, worm gear 313, and punching components 312 connected to it rotate with the housing 30.

[0048] like Figure 2 As shown, each group of punching components 312 may include multiple punching components 312. Each punching component 312 may be rod-shaped, and each punching component 312 has two punching heads 3121 with different diameters at both ends. The middle of each punching component 312 may be connected to the outer periphery of the rotating shaft 311 for transmission, so that the rotational motion of the rotating shaft 311 is converted into the linear motion of the punching component 312. Each punching component 312 is arranged circumferentially along the rotating shaft 311, and the diameter of the punching head 3121 of each punching component 312 is also different. When the housing 30 rotates, it drives the internal punching component 312 to rotate. The appropriate punching head 3121 of the punching component 312 is selected according to the required hole diameter, with the tip of the punching head 3121 facing the document to be punched. To facilitate the operator's observation of whether the punching component 312 containing the punching head 3121 has rotated to a vertical position while the housing 30 is rotated, observation windows (not shown in the figure) can be provided on both end faces of the housing 30. The observation windows are transparent plastic plate-like structures, allowing real-time observation of the internal state of the housing 30, ensuring that the required punching head 3121's tip faces downwards when the housing 30 rotates to a certain angle. In this state, the punching component 312 containing the punching head 3121 is in a vertical position, and the punching component 312 can move vertically, allowing the punching head 3121 below the punching component 312 to extend outside the housing 30.

[0049] It should be noted that each group of punching components 312 may include one, two, three or more punching components 312. For example Figure 1 and Figure 2As shown, a set of punching components 312 may include two punching components 312, one horizontal and one vertical, which are staggered along the axial direction of the rotating shaft 311 without overlapping or interfering with each other. The punching heads 3121 of the two punching components 312 are distributed circumferentially along the rotating shaft 311, and the middle part of each punching component 312 can be a central worm gear 3122. The two ends of the central worm gear 3122 are fixedly connected to punching heads 3121 of different diameters. The central worm gear 3122 is driven by a worm wheel 313 sleeved on the rotating shaft 311. Figure 1 As shown, in each set of punching components 312, the worm gear 3122 in the middle of the two punching components 312 meshes with the same worm wheel 313 sleeved on the rotating shaft 311, and the two punching components 312 are spaced apart along the axial direction of the worm wheel 313, and do not interfere with each other. Figure 2 As shown, when the rotating shaft 311 rotates clockwise, the vertically positioned punching member 312 moves vertically downwards, while the horizontally positioned punching member 312 moves towards... Figure 2 Move to the right in the middle.

[0050] It is understandable that when each group of punching components 312 includes multiple punching components 312, after selecting the punching component 312 with the required diameter punch head 3121, the punching component 312 is rotated so that the required punch head 3121 faces the base 1. A transmission part (e.g., worm gear 313) can be provided on the outer periphery of the rotating shaft 311, and a connecting part (e.g., central worm 3122) can be provided in the middle of the punching component 312. When the rotating shaft 311 rotates, the transmission part is linked to the vertical punching component 312, which moves in the vertical direction. In this state, the connecting part (e.g., central worm 3122) of other punching components 312 can be connected to the transmission part (e.g., worm gear 313), but this connection will not interfere with the vertical punching component 312, and therefore will not affect the movement of the vertical punching component 312. The transmission part can be a worm gear 313 or a collar with a rough surface, raised particles, and high friction. The connecting part can be a central worm 3122 that is adapted to the worm gear 313 or a connecting rod with a rough surface, raised particles, and high friction.

[0051] It should be noted that two, four, six, or more sets of punching components 312 can be provided, for example... Figure 1As shown, six sets of punching components 312 can be provided, the specific number of which is determined according to the size of the document and the number of holes to be punched. Further, each set of punching components 312 may include one, two, three, or more punching components 312, with two punching heads 3121 at both ends of each punching component 312. This is as long as all punching components 312 are mounted on the rotating shaft 311, and the punching heads 3121 are arranged circumferentially along the rotating shaft 311. Furthermore, each punching head 3121 has a different diameter; for example, the diameter of the punching heads 3121 in each set of punching components 312 can be set to 3 mm, 5 mm, 7 mm, 9 mm, or other sizes. The specific structure of the punching head 3121 can be cylindrical at the end near the inside of the housing 30 and conical at the end near the outside of the housing 30. The conical tip is crucial for penetrating the document to be punched.

[0052] It should also be noted that the output of the rotating motor 41 can output positive or negative torque to control the rotation direction of the rotating shaft 311 around its axis, specifically including clockwise or counterclockwise rotation. By changing the rotation direction of the rotating shaft 311, the punching member 312 can be made to perform linear reciprocating motion, for example, moving vertically upward or downward, thereby causing the punching heads 3121 at both ends of the punching member 312 to extend out of the housing 30 or retract into the housing 30.

[0053] like Figure 1 As shown, the document punching tool also includes a drive assembly 4, which includes a first drive component 40. The main function of the first drive component 40 is to provide the punching assembly 3 with the power to press down and punch, enabling the housing 30 to move vertically relative to the base 1. This movement is crucial to ensuring that the punch head 3121 can penetrate the document and create a string hole. The first drive component 40 can be a cylinder, with its output end connected to the housing 30, applying a downward driving force to the top of the housing 30 to drive it to move vertically relative to the base 1. The cylinder can be directly connected to the top of the housing 30. When both ends of the housing 30 are located within the support base 21, the cylinder can also be located at the top of the support base 21, driving the housing 30 by driving the support base 21.

[0054] The specific workflow of the bill punching tool, which includes the aforementioned support component 2, punching component 3, and drive component 4, includes: rotation process, adjustment process, punching process, reset process, and switching step.

[0055] Rotation process: After placing the document to be punched on the base 1 and determining the diameter to be punched, operate the rotating handle 33 to rotate the housing 30. The rotation of the housing 30 drives the punching head 3121 to rotate around the axis of the housing 30, so that the tip of the punching head 3121 corresponding to the diameter to be punched inside the housing 30 is vertically downward and facing the document to be punched. The specific angle of rotation of the housing 30 is determined by the angle between the punching head 3121 of the required diameter and the downward vertical direction.

[0056] Adjustment process: After the previous rotation is completed, when the worm gear 313 is sleeved on the rotating shaft 311, the middle part of the punching component 312 is the central worm 3122, and the punching head 3121 of the required diameter has not extended out of the housing, the rotating shaft 311 is driven to rotate by the rotating motor 41. The worm gear 313 sleeved on the rotating shaft 311 meshes with the central worm 3122 to move the punching component 312, which is in a vertical state, vertically downward until the punching head 3121 with its tip pointing vertically downward extends out of the housing 30, and the length of the extension must be at least equal to the thickness of the document to be punched, to ensure that the document can be completely penetrated.

[0057] Punching Process: After the punching head 3121 and the document to be punched are properly aligned, the first driving component 40 (cylinder) applies a downward driving force to the top of the housing 30. The housing 30, the support base 21, and the vertically downward-pointing punching head 3121 (the punching head 3121 corresponding to the required punching diameter) all move vertically downward. The tip of the punching head 3121 penetrates the document to be punched, punching a row of evenly spaced holes for threading. It should be noted that since the documents to be punched are all paper documents, the paper itself is thin and flexible, and easily torn. Even if multiple documents are stacked together, the driving force indirectly driving the punching head 3121 downward does not need to be too large. Under normal circumstances, the meshing teeth on the worm gear 3122 and worm wheel 313 in the middle will not be damaged due to excessive pressure. Furthermore, the tip of the punching head 3121 can also concentrate the downward pressure at one point, making it easier to penetrate the document without too much pressure. Of course, in order to prevent damage to the meshing teeth on the middle worm 3122 and worm wheel 313 when the housing 30 drives the punching member 3121, which has its tip pointing vertically downward, to move vertically downward, the middle worm 3122 and worm wheel 313 can be made of metal materials with high hardness and high rigidity, such as high-speed steel and chromium-molybdenum alloy steel. In addition, in order to further avoid damage to the meshing teeth on the middle worm 3122 and worm wheel 313, smooth rubber pads or sponge pads or other components that can buffer the impact force can be attached to the surface of each meshing tooth.

[0058] Reset process: After punching is completed, the cylinder exhausts air, and the output end at the bottom of the cylinder pushes the piston and piston rod upward with the spring inside the cylinder. The cylinder drives the housing 30, support seat 21, and punching head 3121 with its tip pointing vertically downward to move vertically upward back to the position before punching. The punching head 3121 leaves the ticket that has been punched.

[0059] If it is necessary to punch a string hole with a different diameter than the previous punch on other documents, a switching step is required. The specific process is as follows: After completing one punch and resetting, operate the rotating handle 33 again to rotate the housing 30 so that the tip of the punch head 3121 of a different diameter is vertically downward toward the document to be punched. That is, by rotating the housing 30 as described above, the punch head 3121 of different diameters is switched, and the specific punch head 3121 of the required diameter is aligned with the document to be punched. For example, if the punch head 3121 used this time is the punch head 3121 at the other end of the punching component 3122 where the punch head 3121 used last time is located, then the housing 30 needs to be rotated 180° to ensure that the punching component 3122 is rotated 180°, thereby switching the required punch head 3121 so that its tip faces the base 1. It should be noted that after the punching component 312 rotates 180°, the rotating shaft 311 needs to be controlled to rotate in the opposite direction to the previous rotation, so as to ensure that the punching component 312 can still move downward in the vertical direction, so that the punching head 3121 extends out of the housing 30.

[0060] The punching tool provided in this embodiment can rotate the housing 30, causing the housing 30 to drive the punching heads 3121 of different diameters of the punching components 312 to rotate. This allows for selection and switching of punching heads 3121 with different diameters according to the required punching diameter, making it widely applicable and able to meet the punching needs of documents of different sizes. Furthermore, multiple sets of punching components 312, evenly spaced horizontally on the rotating shaft 311, can simultaneously punch multiple evenly spaced string holes in the area to be punched on the document, thereby improving punching efficiency. The area to be punched is the area where the preset string holes are located, typically a portion of the four corners or near the edge of the document to be punched. When multiple string holes need to be punched at once, the area to be punched is arranged in a strip along the edge of the document.

[0061] The specific structure of the punching component 312 is described below.

[0062] like Figure 1As shown, the punching component 312 is the key structure for achieving punching of different diameters. Switching between different diameter punching heads 3121 is achieved by rotating and adjusting the punching component 312 in the vertical direction. Each punching component 312 includes a central worm gear 3122 and two punching heads 3121, which are respectively located at both ends of the central worm gear 3122. When the central worm gear 3122 moves linearly back and forth, the punching heads 3121 at both ends also move synchronously back and forth. For example, when the central worm gear 3122 moves up and down vertically, the punching heads 3121 at both ends also move up and down synchronously. Multiple worm gears 313, adapted to the multiple sets of punching components 312, are fitted onto the rotating shaft 311. The worm gears 313 can rotate clockwise or counterclockwise under the drive of the rotating shaft 311.

[0063] When each group of punching components 312 includes one punching component 312, each worm gear 313 is connected to the central worm 3122 of the corresponding punching component 312. That is, when the worm gear 313 rotates with the shaft 311, the rotational motion can be transmitted to the central worm 3122 through the external teeth of the worm gear 313, so that the central worm 3122 moves linearly under the drive of the worm gear 313. When the punching component 312 is in a vertical state, one of the punching heads 3121 at both ends of the central worm 3122 can move vertically out of the through hole 301 of the housing 30, and the other punching head 3121 moves in the same direction and retracts into the housing 30 through the corresponding other through hole 301. The length of the punching member 312 needs to be set to be greater than the vertical height of the housing 30 and exceed the length of the housing 30 by at least the length of one punching head 3121. This ensures that the punching head 3121 at the lower end of the middle worm 3122 of each vertically positioned punching member 312 can extend through the hole 301, and the punching head 3121 at the upper end of the middle worm 3122 can be completely retracted into the housing 30. This allows the housing 30 to protect the upper punching head 3121 and prevent the operator from accidentally touching the tip of the upward-facing punching head 3121.

[0064] like Figure 3As shown, in order to prevent the punch head 3121 from shaking when pressing down, a sleeve 3123 can be sleeved on the end of each punch head 3121 near the middle worm 3122. The sleeve 3123 can be a hollow cylinder with openings at both ends and its inner wall fixedly connected to the outer wall of the punch head 3121. The sleeve 3123 is adapted to the size of the corresponding through hole 301. When the first driving component 40 drives the housing 30 to press down for punching, the cooperation between the outer wall of the sleeve 3123 and the inner wall of the through hole 301 enhances the structural stability and ensures the punching accuracy. In addition, to prevent the connection between the punching member 312 and the worm gear 313 in the middle position from being unstable and falling off the housing 30 when the punching member 312 is in a vertical position, a baffle 3124 can be provided on the outer periphery of the end of each sleeve 3123 near the middle worm gear 3122. The baffle 3124 protrudes from the outer periphery of the sleeve 3123 and its coverage area is larger than the area of ​​the through hole 301, thereby limiting the movement distance of the punching member 312 relative to the housing 30. When the corresponding punching head 3121 and sleeve 3123 pass through the through hole 301, the baffle 3124 will contact the inner wall of the housing 30, preventing the punching head 3121 and sleeve 3123 from continuing to move out of the housing 30. For example, in each of the above-mentioned punching components 312, the diameters of the punching heads 3121 at both ends of the central worm gear 3122 are 3 mm and 5 mm, respectively. When the first set of documents to be punched needs to have a 3 mm hole for threading the rope, and the second set of documents to be punched needs to have a 5 mm hole for threading the rope, the specific process of punching and switching of the punching component 312 is as follows:

[0065] First punching: Operate the rotating handle 33 to rotate the housing 30 so that the tip of the 3 mm diameter punch head 3121 is vertically downward toward the first book of tickets to be punched. If the 3 mm diameter punch head 3121 does not protrude from the housing 30, the rotating shaft 311 needs to be driven to rotate, which drives the worm gear 313 to rotate in the same direction. The meshing part of the worm gear 313 and the middle worm 3122 moves downward under the action of the transmission force, pushing the 3 mm diameter punch head 3121 and its corresponding sleeve 3123 through the through hole 301 and protruding from the housing 30. At this time, the 5 mm diameter punch head 3121 and its corresponding sleeve 3123 also move downward into the housing 30. Continue to drive the housing 30, support 21 and punch head 3121 with a diameter of 3 mm to press down and penetrate the first book of tickets to complete the punching. The cylinder exhausts air, and the output end at the bottom of the cylinder pushes the piston and piston rod upward with the spring in the cylinder. The output end at the bottom of the cylinder drives the housing 30, support 21 and punch head 3121 with a diameter of 3 mm to move upward and reset.

[0066] Switching the punch head 3121: After placing the second set of documents to be punched on the base 1, rotate the housing 30 180° to ensure that the punching component 312 rotates 180°, thereby switching the 5 mm diameter punch head 3121 so that the tip is vertically downward facing the second set of documents to be punched. Since the 5 mm diameter punch head 3121 was stored in the housing 30 during the previous operation, it is necessary to drive the rotating shaft 311 to rotate in the opposite direction to the previous rotation, driving the worm gear 313 to rotate synchronously. The meshing part of the worm gear 313 and the middle worm 3122 moves downward under the action of the transmission force, pushing the 5 mm diameter punch head 3121 and its corresponding sleeve 3123 through the through hole 301. At this time, the 3 mm diameter punch head 3121 and its corresponding sleeve 3123 also move downward into the housing 30.

[0067] Second punching: After switching to the punching head 3121 with a diameter of 5 mm, the cylinder continues to drive the housing 30, support 21 and the punching head 3121 with a diameter of 5 mm to press down and penetrate the second booklet of documents to complete the punching. The cylinder, housing 30, support 21 and punching head 3121 with a diameter of 5 mm then move upward to reset.

[0068] In one specific embodiment of this utility model, the support components 2 are respectively arranged on the left and right ends of the housing 30 in the horizontal direction. The support rod 20 of each support component 2 is arranged in a vertical state. The upper end of the support rod 20 is connected to the bottom end of the support base 21, and the lower end of the support rod 20 is fixedly connected to the base 1. The main function of the support rod 20 is to support the support base 21, thereby supporting both ends of the housing 30 above the base 1 and maintaining a certain distance, so as to ensure that the document to be punched can be placed below the punch head 3121.

[0069] To facilitate the rotation of the housing 30 on the support 21, the housing 30 is configured as a hollow cylindrical shape, and the support 21 is configured as a support block with a mounting hole 211 in the middle corresponding to the end of the housing 30, so that both ends of the housing 30 pass through the mounting hole 211. The cylinder can be set at the top of the support 21. When the punching is pressed down, the cylinder applies pressure to the top of the support 21, and the support 21 can indirectly push the housing 30 to move downward.

[0070] Both ends of the housing 30 are rotatably mounted in the mounting holes 211 of the corresponding support base 21 via a one-way rotation mechanism 32. The one-way rotation mechanism 32 can not only make the housing 30 rotate in a fixed direction within the mounting hole 211 to switch punch heads 3121 of different diameters, but also lock the housing 30 and the support base 21 during punching to avoid unnecessary relative rotation between the housing 30 and the support base 21 when the punching is pressed down, thus affecting the punching accuracy.

[0071] The specific structure of the one-way rotation mechanism 32 will be described below.

[0072] like Figure 4 As shown, the unidirectional rotation mechanism 32 can be a mutually compatible movable pawl 321 and a circumferential toothed groove 322. The circumferential toothed groove 322 includes multiple toothed grooves. The movable pawl 321 is disposed at the end of the housing 30, with one end rotatably connected to the housing 30 and the other end rotatable to protrude from the outer periphery of the housing 30, and can be engaged in a toothed groove. The circumferential toothed groove 322 is disposed on the inner peripheral wall of the mounting hole 211 of a corresponding support 21. The circumferential toothed grooves 322 are distributed along the circumference of the mounting hole 211 on the inner peripheral wall of the mounting hole 211, and the opening direction of the grooves of the circumferential toothed grooves 322 is either clockwise or counterclockwise. The rotation direction of the housing 30 is the same as the opening direction of the grooves of the circumferential toothed grooves 322. The number of movable pawls 321 can be one, two, three or more, and the specific number can be selected as needed.

[0073] The working process of the movable pawl 321 and the circumferential toothed groove 322 includes rotation and locking: When it is necessary to switch the punch head 3121, operate the rotating handle 33 to rotate the housing 30. The free end of the movable pawl 321 slides along the opening direction of the circumferential toothed groove 322 on the inner circumferential wall of the mounting hole 211. The movable pawl 321 rotates to the corresponding toothed groove. After the housing 30 stops rotating, the free end of the movable pawl 321 locks into the bottom of the corresponding toothed groove, so that the housing 30 is locked with the inner wall of the mounting hole 211.

[0074] like Figure 5 As shown, the unidirectional rotation mechanism 32 can also consist of mutually adaptable elastic engaging parts 323 and circumferential slots 324. The circumferential slots 324 can include multiple slots. The elastic engaging part 323 is disposed at the end of the housing 30, with one end protruding from the outer periphery of the housing 30, and can be compressed into the housing 30 under pressure. The circumferential slots 324 are disposed on the inner circumferential wall of the mounting hole 211 of a corresponding support 21. The circumferential slots 324 are distributed along the circumference of the mounting hole 211 on the inner circumferential wall of the mounting hole 211, and the opening direction of the slots 324 is either clockwise or counterclockwise. The tilting direction of the elastic engaging part 323, the rotation direction of the housing 30, and the opening direction of the slots are the same. Specifically, the elastic engaging part 323 can be an elastic block with an internal spring and an external shape adapted to the slot. The number of such blocks can be one, two, three, four, or more, depending on the needs.

[0075] The working process of the elastic locking part 323 and the circumferential groove 324 includes rotation and locking: When it is necessary to switch the punch head 3121, the rotating handle 33 is operated to rotate the housing 30. The elastic locking part 323 is compressed into the housing 30 by the pressure of the inner circumferential wall of the mounting hole 211. After the housing 30 is rotated to the corresponding position, the elastic locking part 323 pops out of the housing 30 and locks into the corresponding groove, so that the housing 30 is locked with the inner wall of the mounting hole 211.

[0076] As mentioned above, in addition to supporting the housing 30 and the punching component 31, the support base 21 of the support component 2 also needs to move vertically downward under the drive of the cylinder during punching. In order to better understand the structure and usage of the support component 2, the specific structure of the support component 2 will be explained.

[0077] like Figure 4 In one specific embodiment of this utility model, the bottom end of each support seat 21 in the support assembly 2 can be provided with a hollow sleeve portion 212 facing downwards. The hollow sleeve portion 212 extends vertically, is hollow inside, and is cylindrical in shape. A sleeve rod portion 201 adapted to the hollow sleeve portion 212 can be formed on the support rod 20. When the cylinder drives the housing 30 and the support seat 21 to press down for punching, the hollow sleeve portion 212 slides vertically from the upper end to the lower end of the sleeve rod portion 201 on the outer periphery of the sleeve rod portion 201. The distance between the support seat 21 and the base 1 decreases, that is, the distance between the punch head 3121 with the tip facing downwards and the base 1 decreases, and it penetrates the document to be punched, thereby realizing the downward punching. The sleeve rod portion 201 can be cylindrical to fit the inner wall of the hollow cylinder.

[0078] In another specific embodiment of this utility model, the support rod 20 in the support assembly 2 can be configured as a spring rod. The spring rod is set in a vertical state, with its upper end fixedly connected to the bottom end of the support seat 21 and its lower end fixedly connected to the base 1. Thus, the spring rod can be compressed by vertical downward pressure, and can extend upward to return to its original position after the pressure is released. When the cylinder drives the housing 30 and the support seat 21 to press down for punching, the bottom end of the support seat 21 applies downward pressure to the upper end of the spring rod, compressing the spring rod and thus realizing the downward punching.

[0079] To facilitate understanding of how to use the punching tool for bills provided in this embodiment, the working process of the punching tool for bills is explained below.

[0080] For example, if a 3mm diameter hole needs to be punched in the first volume of punched tickets, and a 5mm diameter hole needs to be punched in the second volume of punched tickets, the specific steps are as follows:

[0081] Switching to a 3mm diameter punch head 3121: After placing the first set of tickets on the base 1, rotate the housing 30 by turning the handle 33 so that the tip of the 3mm diameter punch head 3121 is vertically downward toward the first set of tickets to be punched. The rotation direction of the housing 30 can be determined according to the groove direction of the circumferential tooth groove 322 or the circumferential slot 324 of the one-way rotation mechanism 32. After the housing 30 is rotated to the corresponding position, the movable pawl 321 or the elastic locking part 323 of the one-way rotation mechanism 32 is matched and locked with a corresponding tooth groove or slot, so that the housing 30 no longer rotates, ensuring that the 3mm diameter punch head 3121 always faces the top of the first set of tickets to be punched.

[0082] Adjusting the punch head 3121: If the 3 mm diameter punch head 3121 does not protrude from the housing 30, the rotating shaft 311 needs to be driven to rotate by the rotating motor 41, which in turn drives the worm gear 313 to rotate in the same direction. The part of the worm gear 313 that meshes with the middle worm 3122 moves downward under the action of the transmission force, pushing the 3 mm diameter punch head 3121 and the corresponding sleeve 3123 through the through hole 301. At this time, the 5 mm diameter punch head 3121 and its corresponding sleeve 3123 also move downward into the housing 30. If the 3 mm diameter punch head 3121 has already protruded from the housing 30, this adjustment step is not required, and proceed directly to the next step.

[0083] Downward punching: Driven by a cylinder, the bottom of the cylinder can apply pressure to the top of the support seat 21. The support seat 21 moves downward by sliding along the outer periphery of the sleeve rod 201 through the hollow sleeve part 212 or by squeezing the spring rod. The support seat 21 drives the housing 30 and the punch head 3121 with a diameter of 3 mm to press down and penetrate the first book of tickets, completing the punching of the rope hole with a diameter of 3 mm.

[0084] Reset: The cylinder exhausts air, and the output end at the bottom of the cylinder pushes the piston and piston rod upward with the spring inside the cylinder. The output end at the bottom of the cylinder drives the support seat 21, the housing 30 and the punch head 3121 with a diameter of 3 mm to move upward and reset.

[0085] Switch to the 5 mm diameter punch head 3121: Remove the first book of tickets, place the second book of tickets to be punched on the base 1, and continue to operate the rotating handle 33 to rotate the housing 30 so that the tip of the 5 mm diameter punch head 3121 is vertically downward and facing the second book of tickets to be punched. After switching to the 5 mm diameter punch head 3121, repeat the above steps to complete the punching of the 5 mm diameter rope hole.

[0086] The document punching tool provided in the above embodiments can rotate the housing 30, causing the housing 30 to drive the punching members 3122 with punching heads 3121 of different diameters to rotate. This allows for selection and switching of punching heads 3121 with different diameters according to the required punching diameter, making it widely applicable and able to meet the punching needs of documents of different sizes. Furthermore, by placing the punching heads 3121 at both ends of the worm gear 3122 in the middle of the punching member 212, when one end of the punching head 3121 extends through the hole 301, the other end of the punching head 3121 can be completely retracted into the housing 30, thus protecting the retracted punching head 3121 from accidental contact by the operator. Multiple sets of punching members 312, evenly spaced horizontally on the rotating shaft 311, can simultaneously punch multiple evenly spaced string holes in the area to be punched on the document, thereby improving punching efficiency. The one-way rotation mechanism 32 between the two ends of the housing 30 and the mounting holes 211 of the support 21 can also realize the rotation and locking of the housing 30 relative to the mounting holes 211, thereby improving the structural stability.
