Description

Technical Field

[0001] This utility model relates to the field of drilling tools, and in particular to a drilling structure and a drilling machine using the drilling structure. Background Technology

[0002] A hole punch is a tool used to punch binding holes in media (e.g., paper, photographs, etc.), such as Chinese utility model patent ZL201920848750.2 (authorization announcement number CN210148291U) and Chinese utility model patent ZL202121836879.5 (authorization announcement number CN215749593U).

[0003] Furthermore, to ensure punching efficiency, multiple punching blades are generally configured, each with its own blade holder. In existing punching machines, each punching blade is an independent, separate structure, and the corresponding blade holders are also independent, separate structures. For example, Chinese utility model patent ZL201320251116.3 (CN203305285U) discloses a punching machine, including a base. A paper scrap outlet is cut through the front side of the base for discharging paper scraps, and a hole spacing marking area is displayed on the rear side. An elongated sliding plate extends upward between the paper scrap outlet and the marking area of ​​the base. The bottom side of the sliding plate, adjacent to the base, has a hole spacing marking area. Several punching blade holders are mounted above the paper scrap outlet on the sliding plate. Each punching blade holder includes a frame and a blade that is longitudinally mounted on the frame and can elastically return to its original position. The blade can cut and punch holes in the paper on the base. For example, Chinese utility model patent with patent number ZL202322095307.1 (authorization announcement number CN220481945U) discloses a paper punch, which includes a shell, a cover, a top plate, a frame, a stamping assembly, and a sliding assembly. The stamping assembly includes a striker, a strike rod, and a spring. The striker is provided at the bottom of the striker. The strike rod is cylindrical and has an inverted "V" shaped cutter head at the bottom. A spring is sleeved on the outer periphery of the strike rod. One end of the spring abuts against the bottom of the striker and the other end abuts against the upper part of the top plate.

[0004] However, in existing punching machines, the separate structure of the punching blade and blade holder is not only cumbersome to manufacture and assemble, but also makes it difficult to guarantee assembly precision. This can easily lead to burrs on the punched holes, or even failure to punch through, resulting in poor punching quality and a poor user experience. Summary of the Invention

[0005] The first technical problem to be solved by this utility model is to provide a punching structure that is easy to process and assemble, in contrast to the existing technology.

[0006] The second technical problem to be solved by this utility model is to provide a punching structure that is easy to process and assemble and has high assembly accuracy, in contrast to the prior art.

[0007] The third technical problem to be solved by this utility model is to provide a punching structure that is easy to process and assemble and has a good punching effect, in contrast to the prior art.

[0008] The fourth technical problem to be solved by this utility model is to provide a drilling machine that applies the above-mentioned drilling structure in light of the prior art.

[0009] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is: a perforated structure, characterized in that it includes a shell and a perforated inner core disposed inside the shell, the perforated inner core comprising:

[0010] The tool holder is a single piece.

[0011] The punching knife assembly is a single piece, constrained in the aforementioned housing, and slides up and down on the aforementioned knife holder to achieve punching, and includes at least two punching knives, each punching knife arranged in a preset array according to the binding holes to be punched;

[0012] as well as

[0013] A return spring, constrained within the aforementioned housing, enables the aforementioned punching tool assembly to tend to move upward and return to its original position when pressed down.

[0014] Furthermore, each of the aforementioned punching tools includes a handle and a cutting head fixed to the handle, and the handles of each punching tool are sequentially connected to form an integral tool base, while the cutting heads are spaced apart on the tool base along the arrangement direction of the aforementioned array. This simplifies the structure of the punching tool assembly and helps ensure that each punching tool performs synchronous punching operations.

[0015] Furthermore, the different heights of the cutting tips of each cutter head can, on the one hand, enable the cutter heads to punch sequentially, thereby reducing the pressing force during punching, and on the other hand, avoid uneven distribution of pressing force on the medium, which could lead to burrs in the punched hole or failure to punch through.

[0016] Furthermore, the cutting tip of each of the aforementioned cutters is located on one side of the free end face of its respective cutter head, and the orientation of the cutter head is different, which is conducive to the uniform distribution of pressure on the medium.

[0017] Furthermore, the blades are arranged at intervals along a straight line, and the tips of each blade are symmetrically arranged along the arrangement direction of the blades, which allows the pressing force to be better distributed evenly on the medium, thereby better avoiding the generation of burrs on the cutting edge, or better avoiding the situation where the blade cannot be penetrated.

[0018] Furthermore, the punching tool set and / or tool holder are die-cast metal parts. This further facilitates the machining and manufacturing of the punching tool set and tool holder, and better ensures the structural robustness of the punching tool set and tool holder.

[0019] Furthermore, the punching core also includes a guide assembly, which comprises a first guide integrally disposed on the punching tool assembly and a second guide integrally disposed on the tool holder. The first guide and the second guide are guided and engaged to allow the punching tool assembly to slide and mount on the tool holder. The guide assembly achieves both the mounting of the punching tool assembly on the tool holder and the sliding mounting of the punching tool assembly and the tool holder to perform punching. The same structure performs two functions, thus simplifying the assembly structure of the punching tool assembly and the tool holder.

[0020] Furthermore, the first guide member is one of a vertically extending guide post and a guide groove that slides vertically with the guide post, while the second guide member is the other. This combination of the guide post and guide groove enables the upper and lower sliding installation of the drilling tool assembly and the tool holder, thus simplifying the assembly structure of the drilling tool assembly and the tool holder.

[0021] Furthermore, the guide post protrudes from the outer surface of the drilling tool assembly or tool holder, and one side of the guide groove is open along its own height direction to form a clearance notch for the guide post to slide up and down at the connection point with the drilling tool assembly or tool holder. This allows the guide post to be engaged in the guide groove and slide up and down along the guide groove to achieve drilling, while ensuring the reliability and smoothness of the drilling action.

[0022] Furthermore, the first guide member is disposed on the aforementioned blade base, thereby simplifying the structure of the punching blade assembly and enabling each blade head to slide up and down more effectively in cooperation with the first and second guide members.

[0023] Furthermore, the cutter base is elongated and block-shaped. The first guide member is an integrally formed guide post protruding from the outer surface of the cutter base, and is evenly spaced along the length of the cutter base, with at least one guide member at each end of the cutter base. The second guide member is a guide groove, corresponding one-to-one with the first guide member. This design helps ensure the stable downward sliding of the cutter base, thereby ensuring the stability and reliability of the drilling action of each cutter head.

[0024] Furthermore, the punching core also includes a spring seat assembly for mounting the aforementioned return spring. This spring seat assembly includes a first spring seat integrally mounted on the aforementioned blade base and a second spring seat integrally mounted on the aforementioned blade base. The return spring extends vertically, with its upper end mounted on the first spring seat and its lower end mounted on the second spring seat. This ensures stable mounting of the return spring and, in the downward-moving state of the punching blade assembly, the elastic force of the return spring can better drive the punching blade assembly upwards to return to its original position.

[0025] Furthermore, the punching core is elongated, and the aforementioned return springs are evenly spaced along the length of the punching core, and are at least located at both ends of the punching core. The aforementioned spring seat assemblies correspond one-to-one with the return springs. This facilitates the stable upward repositioning of the punching tool assembly in its downward state under the elastic force of each return spring, avoiding repositioning failure and ensuring continuous, repeatable punching.

[0026] Furthermore, the top of the outer casing is provided with an operating section, which allows an external pressing element to apply pressure to the aforementioned punching blade assembly, causing it to move downwards relative to the blade holder to achieve punching. Thus, during punching, the pressing element acts on the operating section, causing the punching blade assembly to move downwards, thereby achieving punching of the medium, making operation convenient.

[0027] Furthermore, the operating part is an operating port located on the top of the upper housing. This operating port allows an external pressing member to extend into the housing and press down on the punching tool assembly. In the initial state, the return spring holds the punching tool assembly, keeping it in an upward trend and abutting against the upper housing. This not only simplifies the structure of the operating part but also facilitates the pressing member's action on the punching tool assembly. Furthermore, it ensures the reliability of the punching tool assembly mounting structure in the initial state and guarantees smooth pressing of the punching tool assembly by the pressing member, thus improving the punching success rate.

[0028] Furthermore, the operating part includes a mounting port opened on the top of the upper housing and a button that is movably fitted into the mounting port.

[0029] In the initial state, the button is capped within the mounting opening, while the return spring holds the punch assembly, maintaining its upward trend and abutting against the button. When the pressing member presses the button downwards, the button moves downwards, pushing the punch assembly downwards. By transmitting the pressing force to the punch assembly through the button, the button can press the punch assembly without extending into the housing. Furthermore, in the initial state, the reliability of the punch assembly and button mounting structure is ensured, while also guaranteeing smooth pressing of the punch assembly by the pressing member, thus improving the drilling success rate.

[0030] Furthermore, the outer casing has a transverse insertion slot for inserting a punching medium, which divides the outer casing into an upper casing and a lower casing, and the upper casing and the lower casing are detachably connected.

[0031] Meanwhile, the aforementioned tool holder is provided with a transverse groove that communicates with the inside and outside of the insertion slot and allows the drilling medium to enter the tool holder. This transverse groove divides the tool holder into an upper body and a lower body. The upper body has a first cutting hole corresponding to each cutting head, while the lower body has a second cutting hole corresponding to each cutting head. The first cutting holes and the corresponding second cutting holes are vertically aligned so that the corresponding cutting heads can pass through them sequentially along the vertical direction. During drilling, the medium is first allowed to enter the insertion slot and the transverse groove sequentially from the outside to the inside. Then, the drilling tool assembly moves downward, and each cutting head passes through the corresponding first cutting hole and second cutting hole in sequence to achieve drilling.

[0032] Furthermore, the lower housing is a horizontally arranged plate with a window in the center. The lower base is detachably mounted on the lower housing and covers the window, with each second cutting hole vertically aligned with the window. This connection between the lower base and the lower housing achieves the connection between the cutting tool holder and the lower housing, facilitating a stable installation of the cutting tool holder within the housing.

[0033] Furthermore, the upper surface of the lower seat is flush with the upper surface of the lower housing, and the two together form a placement plane for placing the medium. The lower housing is provided with a positioning member, which is positioned along the arrangement direction of the punching blades and located on one side of each punching blade. In the positioned state, the positioning member protrudes from the placement plane to allow the punched holes on the medium to be aligned. The placement plane ensures stable placement of the medium, while the positioning member positions the punched holes on the medium, aligning the holes from two consecutive punching operations and ensuring effective punching of the medium.

[0034] Furthermore, a vertical mounting hole is provided in the lower housing, and the aforementioned positioning member can be vertically and flexibly installed in the mounting hole so that the positioning member protrudes from the placement plane of the lower housing or is hidden below the placement plane of the lower housing. This serves two purposes: firstly, it enables the positioning member to perform its positioning function; secondly, when not in use, the positioning member can be hidden and stored away. This avoids the positioning member affecting the flatness of the medium on the placement plane during initial drilling, and also prevents the positioning member from being easily damaged due to its protrusion on the top surface of the base.

[0035] The technical solution adopted to further solve the fourth technical problem mentioned above is: a punching machine, characterized in that it applies the punching structure described above.

[0036] Furthermore, the system includes a base with mounting positions for installing the aforementioned perforated structure. These mounting positions facilitate the assembly of the perforated structure onto the base.

[0037] Furthermore, the mounting position includes a mounting groove recessed on the top surface of the base for embedding the aforementioned perforated structure. Providing a mounting groove and embedding the perforated structure within it facilitates a stable assembly of the perforated structure onto the base.

[0038] Furthermore, one side of the mounting groove is inclined from top to bottom along its length toward the direction in which the punched structure is pushed into the mounting groove, forming a guide slope for guiding the punched structure into or out of the mounting groove. The guide slope facilitates the assembly of the punched structure into the mounting groove and also facilitates the removal of the punched structure from the mounting groove.

[0039] Furthermore, a mounting cover is provided on the top surface of the base. The portion of the mounting cover above the aforementioned mounting groove is recessed, and together with the mounting groove, they form a mounting slot for accommodating the aforementioned perforated structure.

[0040] With the aforementioned perforated structure assembled, the outer shell of the perforated structure and the mounting cover are positioned by a snap-fit ​​mechanism to prevent the perforated structure from sliding out of the mounting groove. The mounting groove facilitates stable installation of the perforated structure on the base, while the snap-fit ​​mechanism positions the perforated structure within the groove, preventing it from sliding out or shifting during the perforation process, thus ensuring the reliability of both the assembly and the perforation operation.

[0041] Furthermore, the latching structure includes a first latching block protruding from the outer top surface of the housing and a second latching block disposed on the top wall of the mounting groove, wherein the first latching block has an arc-shaped first guide surface and the second latching block has an arc-shaped second guide surface.

[0042] When the aforementioned punched structure is pushed into the aforementioned mounting groove, the first guide surface and the second guide surface engage to guide and guide the first latching block from the first side of the second latching block to the second side, thus limiting the first latching block. When the punched structure is pulled outward from the aforementioned mounting groove, the first guide surface and the second guide surface engage to guide and guide the first latching block from the second side of the second latching block to the first side, thus disengaging it from the second latching block. This not only ensures a secure latch between the first and second latching blocks (when not subjected to external force), but also ensures smoothness when the punched structure is pushed into and pulled out of the mounting groove by external force, improving the user experience.

[0043] The technical solution adopted to further solve the fourth technical problem mentioned above is as follows: a punching machine, characterized in that it applies the punching structure described above, including a base, the top surface of which is flat and has a recessed mounting groove for the lower housing of the punching structure to be fitted into, and the placement plane of the punching structure is flush with the top surface of the base when the punching structure is fitted into the mounting groove. This facilitates the flat placement of the medium during punching and helps to better ensure the punching effect on the medium.

[0044] The technical solution adopted to further solve the fourth technical problem mentioned above is as follows: a punching machine, characterized in that it applies the punching structure described above, including a base, the punching structure being mounted on the top surface of the base, the pressing element being a handle, one end of the handle being an operating end for hand gripping and the other end being a connecting end, the connecting end being rotatably mounted on the top surface of the base via a rotating shaft, and the operating port allowing the corresponding part of the connecting end to pass through the outer shell to press the punching knife assembly. Using a handle as the pressing element, rotating the handle can press the punching knife assembly, which is not only convenient to operate but also facilitates continuous and repeated punching.

[0045] Furthermore, a pressing pad is provided on the top of the punching blade assembly. In the punching state, when the handle is rotated downwards, the corresponding part of the handle's connecting end passes through the outer shell and abuts against the pressing pad, pressing the punching blade assembly downwards. The pad reduces friction between the handle and the punching blade assembly when the handle presses down, which helps extend the service life of the handle and the punching blade assembly, and thus extends the service life of the punching structure and the punching machine.

[0046] Furthermore, the handle is positioned along the front-to-back direction, and the aforementioned connecting end is an inverted U-shaped plate positioned along the left-to-right direction. The left and right side edges of the connecting end extend downwards along their respective length directions to form pressing plates.

[0047] The aforementioned punching core is elongated and positioned along the left-right direction. Each operating port corresponds to one of the pressing plates, and each operating port is located at the end of the outer casing and is an elongated hole extending along the cross-sectional direction of the upper casing. In the punching state, rotating the handle downwards inserts each pressing plate into its corresponding operating port, pressing down on the punching blade assembly. This allows the handle to better act on the punching blade assembly through the operating part, ensuring the punching blade assembly moves smoothly downwards under the pressure of the handle.

[0048] The technical solution adopted to further solve the fourth technical problem mentioned above is as follows: a punching machine, characterized in that it applies the punching structure described above, including a base, the punching structure being mounted on the top surface of the base, and the pressing member being a pressure plate for pressing the button downwards. Pressing the button of the punching structure down with the pressure plate not only facilitates pressing the button but also ensures that the button moves smoothly downwards under the action of the pressure plate, thereby ensuring the smooth downward movement of the punching blade assembly and thus ensuring the punching effect.

[0049] Furthermore, the pressure plate is hinged to one side of the base, and a long strip-shaped pressing bar is protruding from the lower surface of the pressure plate. When the pressure plate presses down on the punching structure, the pressing bar abuts against the button. By designing the pressing bar and utilizing mechanical principles, not only is effort saved, but the force exerted by the pressure plate on the button is also amplified, thereby increasing the pressing force that drives the punching blade assembly to move downward. This helps to avoid problems such as burrs on the punched holes and unsuccessful punching.

[0050] Compared with the prior art, the advantages of this utility model are as follows: the punching blade assembly is mounted on the blade holder with an upper and lower sliding fit, and the return spring enables the punching blade assembly to tend to move upward and return to its original position when pressed down. During punching, pressing the punching blade assembly downward causes it to move downward along the blade holder to achieve the punching action. After the punching action is completed, it springs back to its original position under the action of the return spring. The punching blade assembly and the blade holder are both integral parts, which, compared with the prior art, facilitates the processing and manufacturing of the punching blade assembly and the blade holder, and also facilitates their assembly. It also helps to ensure assembly accuracy, avoids burrs on the hole edge of the punched hole on the medium, and avoids incomplete punching, thus ensuring the punching effect. Furthermore, in the punching machine of this utility model, the entire punching structure or only the punching blade assembly can be replaced as needed to punch the desired hole shape.

[0076] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0077] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0078] Example 1:

[0079] like Figures 1-22 As shown, a punching machine includes a base 6 on which a punching structure 10 is mounted. The punching structure 10 includes a housing 4 and a punching core disposed in the housing 4. The punching core includes a punching blade assembly 1, a blade holder 2, and a return spring 3.

[0080] Furthermore, in this invention, the punching knife assembly 1 is a single piece, constrained within the outer casing 4, and includes at least two punching knives. Each punching knife is arranged in a preset array according to the mounting holes to be punched. In this embodiment, specifically, the punching knives are arranged side-by-side along a straight line. Furthermore, the knife holder 2 is also a single piece, allowing the punching knife assembly 1 to slide up and down for punching. In addition, the return spring 3 is constrained within the outer casing 4 and enables the punching knife assembly 1 to tend to move upwards and return to its original position when pressed down.

[0081] As can be seen from the above, in the punching machine of this utility model, the aforementioned punching knife assembly 1 is mounted on the knife holder 2 in an upward and downward sliding manner, while the return spring 3 enables the punching knife assembly 1 to have an upward tendency to return to its original position when it is pressed down. During punching, pressing the punching knife assembly 1 downward causes it to move downward along the knife holder 2 to achieve the punching action. After the punching action is completed, it springs back to its original position under the action of the return spring 3. The punching knife assembly 1 and the knife holder 2 are both integral parts. Compared with the prior art, this not only facilitates the processing and manufacturing of the punching knife assembly 1 and the knife holder 2, but also facilitates their assembly. It also helps to ensure assembly accuracy, avoids burrs on the edge of the punched hole on the medium, and prevents incomplete punching, thus ensuring the punching effect.

[0082] Furthermore, each of the aforementioned punching tools includes a handle and a cutting head 12 fixed on the handle, and the handles of each punching tool are sequentially connected to form an integral tool base 11, while the cutting heads 12 are spaced apart on the tool base 11 in a straight line, such as... Figure 16 and Figure 17 As shown. This simplifies the structure of the punching tool assembly 1 and helps ensure that each punching tool performs synchronous punching actions. In this embodiment, the aforementioned tool base 11 is a horizontally extending block.

[0083] Furthermore, each of the aforementioned cutter heads 12 is a vertically extending column, with one end fixed to the aforementioned cutter base 11, and the center of the end face (i.e., the free end face) of the other end is respectively provided with a punched hole 1210, such as... Figure 8 As shown. This simplifies the structure of each cutter head 12, facilitating the punching of holes of the desired shape on the medium during the punching process. In this embodiment, the specific shape of the punching holes 1210 on each cutter head 12 can be adjusted as needed; they can be designed to be consistent or different, for example, round holes, mushroom holes, or square holes. The hole diameter can also be designed as needed, for example, 2mm, 4mm, or 5mm. Furthermore, the spacing between adjacent cutter heads 12 can also be adjusted as needed. Therefore, the entire punching structure 10 can be replaced according to the specific punching requirements, or only a portion of the punching cutter group 2 in the punching structure 10 can be replaced to punch out the desired hole shape.

[0084] Furthermore, such as Figure 16 As shown, the heights of the cutting tips 121 of each of the aforementioned cutter heads 12 are different. On the one hand, this allows for sequential punching by each cutter head 12, thereby reducing the pressing force during punching. On the other hand, it facilitates the even transmission of pressing force to the medium through each cutter head 12, which helps to avoid burrs or partial failure to punch through the medium due to uneven distribution of pressing force. Furthermore, as... Figure 8 As shown, the cutting edge 121 of each of the above-mentioned cutter heads 12 is located on one side of the free end face of the cutter head 12, and the orientation of the cutting edge 12 is different, which is beneficial to the uniform distribution of pressure on the medium. Preferably, as shown in the figure Figure 17 As shown, the aforementioned cutting heads 12 are arranged at intervals along a straight line, and the cutting tips 121 of each cutting head 12 are symmetrically arranged from left to right along the arrangement direction of the cutting heads 12. This allows the pressing pressure to be better distributed evenly on the medium, better avoiding burrs on the cutting edge, or better avoiding the situation where the cutting head cannot be penetrated. Specifically, in this embodiment, in the straight line array formed by the aforementioned cutting heads 12, two adjacent cutting heads 12 are grouped together, and the height and orientation of the cutting tips 121 of each cutting head 12 in each group (adjacent groups are arranged alternately) are the same, such as... Figure 16As shown in the box in the middle. This allows the pressing pressure to be better distributed along the arrangement direction of each cutter head 12, thereby better ensuring the smoothness of the hole edge of the punched hole on the medium, and also better avoiding the occurrence of incomplete punching. In addition, it can also facilitate the processing and manufacturing of the punching knife set 1 to a certain extent.

[0085] Furthermore, in this embodiment, the aforementioned punching tool assembly 1 and / or tool holder 2 are die-cast metal parts, which further facilitates the processing and manufacturing of the punching tool assembly 1 and tool holder 2, and can better ensure the structural robustness of the punching tool assembly 1 and tool holder 2. The tool base 11 of the punching tool assembly 1 is hollow, which helps reduce the weight and production cost of the punching tool assembly 1, and thus helps reduce the overall weight and production cost of the punching machine.

[0086] Furthermore, the aforementioned punching core also includes a guide assembly, which comprises a first guide member 111 integrally disposed on the aforementioned punching tool assembly 1 and a second guide member 22 integrally disposed on the aforementioned tool holder 2. The first guide member 111 and the second guide member 22 guide and cooperate to allow the aforementioned punching tool assembly 1 to be slidably mounted on the aforementioned tool holder 2. The guide assembly realizes both the mounting of the punching tool assembly 1 on the tool holder 2 and the slidable mounting of the punching tool assembly 1 and the tool holder 2. The same structure achieves two functions, thereby simplifying the assembly structure of the punching tool assembly 1 and the tool holder 2.

[0087] Preferably, the first guide member 111 is one of a vertically extending guide post and a guide groove that slides vertically with the guide post, while the second guide member 22 is the other. This arrangement of the guide post and guide groove enables the drilling tool assembly 1 and the tool holder 2 to slide vertically together, thus simplifying the assembly structure of the drilling tool assembly 1 and the tool holder 2. More preferably, the guide post protrudes from the outer surface of the drilling tool assembly 1 or the tool holder 2, and one side of the guide groove opens along its height to form a clearance notch 241 (e.g., for sliding up and down at the connection between the guide post and the drilling tool assembly 1 or the tool holder 2). Figure 13 , Figure 14 as well as Figure 15 As shown in the figure, this allows the guide post to be inserted into the guide groove and slide up and down along the guide groove to achieve drilling, and ensures the reliability and smoothness of the drilling action.

[0088] In this embodiment, specifically, the first guide member 111 is disposed on the blade base 11, thereby simplifying the structure of the punching tool assembly 1 and allowing each blade 12 to slide up and down more effectively in cooperation with the first guide member 111 and the second guide member 22. Specifically, as shown... Figures 13-15As shown, the blade base 11 is elongated in shape. The first guide member 111 is an integrally formed guide post protruding from the outer surface of the blade base 11, and the first guide member 111 is evenly spaced along the length of the blade base 11, and is provided at least at both ends of the blade base 11. The second guide member 22 is a guide groove, and corresponds one-to-one with the first guide member 111. This helps to ensure the stable downward sliding of the blade base 11, thereby helping to ensure the stability and reliability of the drilling action of each blade head 12. In this embodiment, each guide post is a cylinder, and the blade holder 2 is a horizontally extending plate-shaped block. A vertically extending guide cylinder 24 with a frustum-shaped shape is arranged on the top surface of the blade holder 2, and the inner cavity of each guide cylinder 24 forms the aforementioned guide groove with cylindrical groove walls.

[0089] Furthermore, the aforementioned punching core also includes a spring seat assembly for mounting the aforementioned return spring 3. This spring seat assembly includes a first spring seat 112 integrally mounted on the aforementioned blade base 11 and a second spring seat 23 integrally mounted on the aforementioned blade holder 2. The aforementioned return spring 3 extends vertically, with its upper end mounted on the aforementioned first spring seat 112 and its lower end mounted on the aforementioned second spring seat 23. This achieves stable mounting of the return spring 3, and also allows the elastic force of the return spring 3 to better drive the punching blade assembly 1 upwards and reset when the punching blade assembly 1 is in a downward state. In this embodiment, as... Figure 15 As shown, the first spring seat 112 is a block protruding vertically on the outer surface of the blade base 11, and the second spring seat 23 is a block protruding vertically on the top surface of the blade holder 2, directly opposite the first spring seat 112. Preferably, the drilling core is elongated, and the return springs 3 are evenly spaced along the length of the drilling core, and are at least located at both ends of the drilling core. The spring seat group corresponds one-to-one with the return spring 3. This facilitates the stable upward repositioning and resetting of the drilling blade group 1 in the downward state under the elastic force of each return spring 3, avoiding resetting failure and ensuring continuous repeated drilling.

[0090] Furthermore, the top of the upper housing 41 is provided with an operating section, which allows an external pressing element to apply pressure to the punching knife assembly 1, causing it to move downward relative to the knife holder 2 to achieve punching. In this way, when punching, the punching knife assembly 1 can be moved downward by the pressing element acting on the operating section to achieve punching of the medium, which is convenient to operate.

[0091] In this embodiment, specifically, as follows: Figure 7 and Figure 9As shown, the aforementioned operating part is an operating port 411 located on the top of the upper housing 41. This operating port 411 allows an external pressing member to extend into the housing 4 and press down on the punching tool assembly 1. Furthermore, in the initial state, the return spring 3 holds the punching tool assembly 1, maintaining its upward trend and abutting against the upper housing 41. This not only simplifies the structure of the operating part but also facilitates the pressing member's action on the punching tool assembly 1. Furthermore, it ensures the reliability of the punching tool assembly 1's mounting structure in the initial state and guarantees smooth pressing of the punching tool assembly 1, thus improving the punching success rate.

[0092] Furthermore, such as Figure 9 As shown and Figure 12 As shown, the outer casing 4 has a transverse insertion slot 40 for inserting a punching medium. This insertion slot 40 divides the outer casing 4 into an upper casing 41 and a lower casing 42, which are detachably connected. Simultaneously, the tool holder 2 has a transverse groove 20 that communicates with the insertion slot 40 and allows the punching medium to extend into the tool holder 2. This transverse groove 20 divides the tool holder 2 into an upper body 21a and a lower body 21b. The upper body 21a has a first punch hole 211 corresponding to each of the punch heads 12, while the lower body 21b has a second punch hole 212 corresponding to each of the punch heads 12. The first punch holes 211 and the corresponding second punch holes 212 are vertically aligned so that the corresponding punch heads 12 can pass through sequentially along the vertical direction. When drilling, the medium is first introduced into the insertion groove 40 and the transverse groove 20 from the outside to the inside. Then, the drilling tool group 1 moves down, and each tool head 12 passes through the corresponding first tool hole 211 and second tool hole in sequence to achieve drilling.

[0093] Furthermore, in this embodiment, the lower housing 42 is a horizontally arranged plate with a through-hole window 4210 in the center. The lower base 21b is detachably mounted on the lower housing 21b and covers the window 4210, with each second cutting hole 212 vertically aligned with the window 4210. Thus, the connection between the lower base 21b and the lower housing 42 achieves the connection between the cutting tool holder 21 and the lower housing 42, facilitating a stable installation of the cutting tool holder 21 within the outer casing 4. In addition, in this embodiment, the upper housing 41 is a cover-shaped structure that covers the lower housing 42 from top to bottom, and the two are connected by a snap-fit ​​assembly 44, such as... Figure 12 As shown.

[0094] Furthermore, the upper surface of the lower seat 21b is flush with the upper surface of the lower housing 42, and the upper surfaces of the lower housing 42 together form a placement plane 420 for placing the medium. A positioning member 5 is provided on the lower housing 42, which is positioned along the arrangement direction of the punching blades and located on one side of each punching blade. In the positioned state, the positioning member 5 protrudes from the placement plane 420 to accommodate the punched holes on the medium. Thus, the positioning member 5 enables the positioning of the punched holes on the medium, aligning the holes from two consecutive punching operations and ensuring the effective punching of the medium.

[0095] Furthermore, such as Figure 22 As shown, a vertical mounting hole 4200 is provided in the lower housing 42, and the positioning member 5 is vertically and flexibly disposed in the mounting hole 4200 so that the positioning member 5 protrudes on the placement plane of the lower housing 42 (e.g., Figure 1 (as shown), or hidden below the placement plane of the lower housing 42 (as shown). Figure 20 (As shown). This design serves two purposes: firstly, it enables the positioning of the positioning element 5; secondly, it allows the positioning element 5 to be hidden and stored when not in use. By hiding the positioning element 5, it prevents it from affecting the flatness of the medium on the placement plane 420 during the initial drilling, and thirdly, the protrusion of the positioning element 5 on the top surface of the base 6 makes it susceptible to damage.

[0096] In this embodiment, specifically, as follows: Figure 22 As shown, the positioning element 5 is vertically arranged and includes a base 51 and a positioning post 52. The base 51 is gate-shaped, and the positioning post 52 is integrally protruding from the top surface of the base 51 and connected to a hole on the medium. The base 51 is slidably fitted into the mounting channel 4200 with vertical guides. The base 6 has a mounting chamber 60. When the perforated structure 10 is assembled on the base 6, the mounting channel 4200 communicates vertically with the mounting chamber 60, and the corresponding part of the lower housing 42 forms part of the top wall of the mounting chamber 60. A limit strip 424 is horizontally spaced at the lower end of the mounting channel 4200. In the positioning state (first state), when the positioning element 5 is raised to its highest position, the outer top surface of the base 51 is flush with or lower than the top surface of the base 6, and the positioning post 52 is fully exposed. Figure 1 and Figure 22 As shown. In the unpositioned state (second state), the positioning member 5 descends to its lowest point, the inner top surface of the base 51 abuts against the limiting strip 424, and the positioning post 52 is completely hidden in the mounting channel 4200. This allows the positioning member 5 to smoothly move up and down along the mounting channel 4200, and it can be stably positioned in the second state by the limiting strip 424.

[0097] Furthermore, the aforementioned mounting chamber 60 is provided with a top support 7 that can slide horizontally back and forth relative to the aforementioned positioning member 5, allowing the positioning member 5 to move up and down along the aforementioned mounting channel 4200, such as... Figure 19 As shown. In the second state described above, the supporting member 7 is located beside the positioning member 5. When the supporting member 7 is moved to below the positioning member 5, it can support the positioning member 5 upwards, so that the positioning member 5 is in the first state described above and is positioned. In the first state described above, the supporting member 7 is moved to detach from the positioning member 5, and the positioning member 5 falls along the mounting channel 4200 under its own gravity. The supporting member 7 realizes the supporting drive for the positioning member 5 to rise along the mounting channel 4200. When the positioning member 5 rises to its highest height, it can be positioned so that the positioning member 5 is stably maintained in the first state described above.

[0098] Furthermore, specifically, such as Figure 19 As shown, the aforementioned supporting member 7 includes a horizontally extending sliding plate 71 and a top block 73 protruding from one side of the upper surface of the sliding plate 71 for supporting the aforementioned positioning member 5. The top surface of the top block 73 is flat, while the first side surface 731 is an inclined surface sloping outward from top to bottom. In the second state, the aforementioned supporting member 7 is translated until the first side surface 731 of the top block 73 abuts against the positioning member 5. As the supporting member 7 continues to translate, the positioning member 5 moves upward along the first side surface 731 until it reaches the top surface of the top block 73, and the positioning member 5 is in the aforementioned first state. The other end of the upper surface of the aforementioned sliding plate 71 is provided with a lever 72 for actuating the aforementioned supporting member 7, and the top wall of the aforementioned mounting chamber 60 is vertically provided with a guide groove 61 extending along the translational direction of the aforementioned supporting member 7. The lever 72 is tightly fitted into the guide groove 61 and can slide back and forth along the guide groove 61. Furthermore, when the toggle block 72 slides to one end of the guide groove 61, the positioning member 5 is in the first state, and when the toggle block 72 slides to the other end of the guide groove 61, the positioning member 5 is in the second state.

[0099] Furthermore, the base 6 is provided with mounting positions for the perforated structure 10. To ensure stable installation of the perforated structure 10 on the base 6, in this embodiment, as follows... Figure 6 As shown, the top surface of the base 6 is provided with a mounting groove 62 for the aforementioned perforated structure 10 to be fitted. Preferably, the front side of the mounting groove 62 slopes backward toward the perforated structure 10 from top to bottom along its own length direction to form a guide slope 621 for guiding the perforated structure 10 into or out of the mounting groove 62 (e.g., Figure 6(As shown). The guide ramp 621 facilitates the assembly of the drilling structure 10 into the mounting groove 62, and also facilitates the removal of the drilling structure 10 from the mounting groove 62. Preferably, the top surface of the base 6 is covered with a mounting cover 63, the portion of which is recessed above the mounting groove 62, and together with the mounting groove 62, forms a mounting groove 631 for accommodating the drilling structure 10, as shown. Figure 5 and Figure 6 As shown. With the aforementioned perforated structure 10 assembled, the outer shell 4 of the perforated structure 10 and the mounting cover 63 are positioned by the snap-fit ​​structure 43 to prevent the perforated structure 10 from sliding out of the mounting groove 631. The mounting groove 631 facilitates the stable installation of the perforated structure 10 on the base 6, while the snap-fit ​​structure 43 positions the perforated structure 10 within the mounting groove 631, preventing it from sliding out or shifting during the perforation process, thus ensuring the reliability of the perforated structure 10 assembly and the perforation operation.

[0100] Specifically, such as Figure 4 and Figure 5 As shown, the aforementioned latching structure 43 includes a first latching block 414 protruding from the outer top surface of the housing 4 and a second latching block 6311 disposed on the top wall of the mounting groove 631. The first latching block 414 has an arc-shaped first guide surface 431, and the second latching block 6311 has an arc-shaped second guide surface 432. When the aforementioned punching structure 10 is pushed into the aforementioned mounting groove 631 from front to back, the first guide surface 431 and the second guide surface 432 guide and engage, sliding the first latching block 414 from the front side of the second latching block 6311 to the rear side and limiting the first latching block 414. When the punching structure 10 is pulled outward from the aforementioned mounting groove 631, the first guide surface 431 and the second guide surface 432 guide and engage, sliding the first latching block 414 from the rear side of the second latching block 6311 to the front side and disengaging from the second latching block 6311. This not only ensures the secure locking of the first latching block 414 and the second latching block 6311 (without external force), but also ensures the smoothness of pushing the drilled structure 10 into and pulling it out of the mounting groove 631 by external force, thus improving the user experience.

[0101] Furthermore, preferably, the top surface of the base 6 is a plane, and the mounting groove 62 is for the lower housing 42 of the perforated structure 10 to be fitted into. And when the perforated structure 10 is fitted into the mounting groove 62, the placement plane is flush with the top surface of the base 6 (e.g., ...). Figure 1 and Figure 2 As shown in the figure, this facilitates the flat placement of the medium during the drilling process, which helps to better ensure the drilling effect on the medium.

[0102] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the pressing component is a handle 8. One end of the handle 8 is an operating end 81 for hand gripping, and the other end is a connecting end 82. The connecting end 82 is rotatably mounted on the top surface of the base 6 via a rotating shaft 83. The operating port 411 allows the corresponding part of the connecting end 82 to pass through the outer shell 4 to press the punching knife assembly 1. By using the handle 8 as the pressing component, rotating the handle 8 can press the punching knife assembly 1, which is not only convenient to operate but also facilitates continuous and repeated punching.

[0103] Preferably, such as Figure 10 As shown, a pressing pad 415 is provided on the top of the aforementioned punching knife assembly 1. In the punching state, when the handle 8 is rotated downwards, the corresponding part of the connecting end 82 of the handle 8 passes through the outer shell 4 and abuts against the pressing pad 415, pressing the punching knife assembly 1 downwards. By providing the pad 415, the friction between the handle 8 and the punching knife assembly 1 when the handle 8 presses down is reduced, which helps to extend the service life of the handle 8 and the punching knife assembly 1, and thus helps to extend the service life of the punching structure 10 and the punching machine.

[0104] Specifically, such as Figure 1 and Figure 2 As shown, the handle 8 is positioned along the front-to-back direction, and the connecting end 82 is an inverted U-shaped plate positioned along the left-to-right direction. The left and right side edges of the connecting end 82 extend downwards along their own length to form pressing plates 9. The perforated inner core is elongated and positioned along the left-to-right direction. The operating ports 411 correspond one-to-one with each pressing plate 9, and each operating port 411 is located at the end of the outer shell 4 and is an elongated hole extending along the cross-sectional direction of the upper shell 41. In the perforation state, rotating the handle 8 downwards causes each pressing plate 9 to insert into the corresponding operating port 411 and press down on the perforation knife assembly 1. This allows the handle 8 to better act on the perforation knife assembly 1 through the operating part, ensuring that the perforation knife assembly 1 moves smoothly downwards under the pressure of the handle 8. Correspondingly, there are also two pressing pads 415, each corresponding one-to-one with the pressing plate 9.

[0105] Example 2:

[0106] like Figures 23-25 As shown, unlike Embodiment 1, in this embodiment, the operating part includes a mounting opening 410 formed on the top of the upper housing 41 and a button 412 (e.g., ...) that is movably fitted into the mounting opening 410. Figure 25(As shown). In the initial state, the button 412 is uppertably positioned within the mounting opening 410, while the return spring 3 holds the punch assembly 1, maintaining its upward trend and abutting against the button 412. When the pressing member presses the button 412 downwards, the button 412 moves downwards, pushing the punch assembly 1 downwards. By transmitting the pressing force of the pressing member onto the punch assembly 1 through the button 412, the button 412 can press the punch assembly 1 without extending into the housing 4. Furthermore, in the initial state, the reliability of the punch assembly 1 and the button 412 mounting structure is ensured, while also guaranteeing smooth pressing of the punch assembly 1 by the pressing member, thus improving the punching success rate.

[0107] Furthermore, in this embodiment, the pressing element is a pressure plate 9 for pressing the button 412 downwards. Pressing the button 412 of the drilling structure 10 down using the pressure plate 9 not only facilitates pressing the button 412 but also ensures that the button 412 moves smoothly downwards under the action of the pressure plate 9, thereby ensuring the smooth downward movement of the drilling tool assembly 1 and consequently ensuring the drilling effect. Preferably, as... Figure 23 As shown, the pressure plate 9 is hinged to the rear side of the base 6, and a long strip-shaped pressing strip 91 is protruding from the lower surface of the pressure plate 9. When the pressure plate 9 presses down on the punching structure 10, the pressing strip 91 abuts against the button 412. By designing the pressing strip 91, and utilizing mechanical principles, not only is effort saved, but the force exerted by the pressure plate 9 on the button 412 is also amplified, thereby increasing the pressing force that drives the punching tool assembly 1 to move downward. This helps to avoid problems such as burrs on the punched holes and unsuccessful punching.

[0108] Preferably, in this embodiment, the punching machine is elongated and arranged along the left-right direction. The pressing strip 91 is arranged along the length of the pressure plate 9, and the button 412 is also elongated and arranged along the left-right direction. In the punching state, the button 412 abuts against the pressing strip 91 vertically along its own length. Further, in this embodiment, the button 412 is a vertically arranged cover with a downward opening. The edge of the cover extends horizontally outward in the circumferential direction to form a limiting protrusion 4121. When the button 412 is in a limited position, the limiting protrusion 4121 abuts against the lower edge of the mounting opening 410 vertically. Figure 25 As shown.
