Description

Technical Field

[0001] This utility model relates to the field of manual punching tools, and more particularly to a punching machine. Background Technology

[0002] A hole punch is a tool used to punch binding holes in media (e.g., paper, photographs, etc.). Existing hole punches generally achieve punching by pressing down on the punching mechanism with a handle. For example, Chinese utility model patent ZL201920848750.2 (authorization announcement number CN210148291U) discloses a press-type document punching device, including a base with a support on the base. A pressing block is hinged to the support and can rotate around a horizontal axis. A handle is located at the end away from the hinge. A vertically movable punch with its head facing downwards is located below the pressing block. A sleeve that cooperates with the punch is provided on the support. A pressure plate is located directly below the pressing block, with one end of the pressure plate hinged to the support and rotatable around a horizontal axis. The pressure plate and the pressing block are connected by a spring. A return spring is provided on the sleeve to bring the punch to its highest position. For example, Chinese utility model patent ZL202121836879.5 (authorization announcement number CN215749593U) discloses a punching device for binding accounting documents, relating to the field of financial office supplies technology. The device features a machine body fixedly connected to the rear top of the workbench, with symmetrically distributed hot riveting handles slidably connected to the machine body. A riveting head assembly is located on one side of the bottom of the machine body, and a drill bit assembly is located to the right of the riveting head assembly. A drilling assembly is also provided, and the drilling assembly is threadedly connected to the front top of the workbench. Storage components are fixedly connected to both sides of the workbench. It is evident that existing punching machines, due to the rotating handle installation, are prone to accidental empty punching when not in use, and are also inconvenient for storage and transportation. Summary of the Invention

[0003] The first technical problem to be solved by this invention is to provide a punching machine that can limit the handle and avoid dry punching, in contrast to the prior art.

[0004] The second technical problem to be solved by this utility model is to provide a punching machine that can lock the handle to stop it from moving, in contrast to the prior art.

[0005] The technical solution adopted by this utility model to solve at least one of the above-mentioned technical problems is as follows: a drilling machine, including a base, a handle, and a drilling mechanism, wherein one end of the handle is an operating end for hand gripping and the other end is a connecting end, the connecting end is rotatably mounted on the top surface of the base via a rotating shaft, and the handle can press down on the drilling mechanism to achieve drilling, characterized in that it further includes a locking member movably disposed on one side of the handle for locking the handle, the locking member having a first notch.

[0006] Furthermore, the aforementioned locking element has at least two states:

[0007] In the first state, the first notch is opposite to the connecting end and allows the end of the connecting end to pass through;

[0008] In the second state, the first notch and the connecting end are offset from each other, and the locking member can limit the end of the connecting end so that the handle cannot be rotated and the punching mechanism is pressed down.

[0009] Furthermore, the locking member also includes a locking portion, and the end of the handle connection has a second notch. In the second state, the locking portion is opposite to the second notch and engages with it to stop the handle. By providing the second notch and utilizing its engagement with the locking portion on the locking member to stop the handle, not only is accidental activation of the punching mechanism prevented when not in operation, but the handle is also prevented from rotating, thus facilitating storage and transportation.

[0010] Furthermore, in the second state, the operating end of the handle is adjacent to the top surface of the base. This further ensures the reliability of the handle locking, and placing the handle horizontally facilitates the storage and transportation of the punch.

[0011] Furthermore, the locking part is elongated, and in the second state described above, the extending direction of the locking part is perpendicular to the extending direction of the second notch. By designing the extending direction of the locking part and the extending direction of the second notch in the above way, the reliability of the locking handle when they cooperate can be improved.

[0012] Furthermore, a torsion spring is installed on the shaft of the handle. In the initial state, the handle is tilted along its length, with the connecting end located at the lower end of the handle and the operating end located at the upper end.

[0013] The aforementioned locking member is a horizontally extending, elongated plate. This plate is positioned perpendicular to the length direction of the handle and can move back and forth along its own length. The aforementioned locking portion and the aforementioned first notch are arranged side by side along the length direction of the locking member.

[0014] In the initial state, the locking member is located above the connecting end of the handle. Rotating the operating end of the handle downwards causes the connecting end to rotate upwards until the operating end is close to the top surface of the base. Moving the locking member aligns its locking portion with the connecting end of the handle, causing it to engage in the second notch of the connecting end. Simultaneously, the torsion spring deforms, causing the connecting end to tend to rotate downwards to reset. This simplifies the structure of the locking member, facilitating locking and unlocking of the handle by operating it (i.e., moving the locking member along its length). Furthermore, when the handle is locked, the torsion spring ensures the handle remains reliably locked.

[0015] Furthermore, the locking part is the plate portion of the locking member adjacent to the first notch. This simplifies the structure of the locking member and allows it to switch between unlocked and locked states.

[0016] Furthermore, a bracket is vertically arranged on the top surface of the base along the length of the locking member. Each end of the bracket has a mounting opening, and the two ends of the locking member are respectively connected to the corresponding mounting openings. The locking member can move back and forth relative to each mounting opening along its own length. This allows for both the installation of the locking member and its movement along its own length, enabling switching between unlocked and locked states.

[0017] Furthermore, the locking member is provided with a lever for moving the locking member back and forth along its own length. By providing the lever, the user can easily move the locking member back and forth along its own length, thus enabling the user to switch between unlocked and locked states.

[0018] Furthermore, a housing is provided on the top surface of the base to form a mounting cavity. The connecting end of the handle and the locking member are both housed in this mounting cavity. A guide hole extending along the length direction of the locking member is provided on the housing. The lever is embedded in the guide hole and can move back and forth along the length direction of the guide hole. When the lever is located at one end of the guide hole, the locking member is in the first state, and when the lever is located at the other end of the guide hole, the locking member is in the second state. The lever is exposed outside the housing through the guide hole, which facilitates the user's operation of the lever. The sliding of the lever in the guide hole helps to ensure the smooth movement of the locking member along its own length direction, thereby ensuring the reliability of the unlocking and locking state switching control.

[0019] Furthermore, the lever includes a base plate extending along the length of the locking member and a block protruding from one side of the base plate. This block is fitted into the guide hole. A mounting post protrudes from the other side of the base plate and is tensioned into a mounting hole on the locking member, allowing the lever to be mounted on the upper surface of the locking member. This ensures the lever is securely mounted on the locking member and facilitates easy assembly and disassembly of the lever from the locking member.

[0020] Compared with the prior art, the advantages of this utility model are as follows: A locking member is provided, which has a first notch. In the first state, the first notch is opposite to the connecting end, allowing the end of the connecting end to pass through, thus enabling the handle to rotate normally up and down and ensuring the normal drilling function of the punch. In the second state, the first notch is offset from the connecting end, and the locking member can limit the end of the connecting end, preventing the handle from rotating and pressing down on the punching mechanism. This avoids the handle pressing down on the punching mechanism when not in operation (i.e., not drilling), thus preventing the punching mechanism from being mistakenly driven (i.e., dry-firing), improving the reliability of the device structure, and facilitating storage and transportation.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] 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.

[0031] like Figures 1-8 As shown, a punching machine includes a base 1, a handle 2, and a punching mechanism 3. One end of the handle 2 is an operating end 21 for hand gripping, and the other end is a connecting end 22. The connecting end 22 is rotatably mounted on the top surface of the base 1 via a pivot 23. The handle 2 can press down on the punching mechanism 3 to achieve punching. Furthermore, it includes a locking member 4 movably disposed on one side of the handle 2 for locking the handle 2. The locking member 4 has a first notch 41. The locking member 4 has at least two states:

[0032] In the first state, the first notch 41 is opposite to the connecting end 22, and the end of the connecting end 22 can pass through it, such as... Figure 5 As shown;

[0033] In the second state, the first notch 41 and the connecting end 22 are offset from each other, and the locking member 4 can limit the end of the connecting end 22, so that the handle 2 cannot rotate and press down the punching mechanism 3, such as Figure 6 As shown.

[0034] As can be seen from the above, the punching machine of this utility model is equipped with a locking member 4, which has a first notch 41. In the first state, the first notch 41 of the locking member 4 is opposite to the connecting end 22 and allows the end of the connecting end 22 to pass through, thereby enabling the handle 2 to rotate normally up and down and ensuring the normal punching function of the punching machine (e.g., Figure 5(As shown). In the second state, the locking member 4 has the first notch 41 offset from the connecting end 22, and the locking member 4 can limit the end of the connecting end 22 so that the handle 2 cannot rotate and press down the punching mechanism 3. This prevents the handle 2 from pressing down the punching mechanism 3 when it is not in operation (i.e., not punching), thus preventing the punching mechanism 3 from being accidentally driven (i.e., dry-punching), improving the reliability of the device structure, and facilitating storage and transportation.

[0035] Furthermore, the aforementioned locking member 4 also includes a locking portion 42, and the end of the connecting end 22 of the aforementioned handle 2 has a second notch 2211. In the second state described above, the locking portion 42 is opposite to the second notch 2211 and engages with the second notch 2211 to stop the handle 2 (e.g., Figure 6 (As shown). By creating a second notch 2211, the handle 2 is stopped by engaging the locking part 42 on the locking member 4. This prevents the punching mechanism 3 from being accidentally driven (i.e., avoiding dry punching) and also prevents the handle 2 from rotating, thus facilitating storage and transportation. Preferably, in the second state described above, the operating end 21 of the handle 2 is adjacent to the top surface of the base 1 (i.e., the handle 2 is in a nearly horizontal state), such as... Figure 4 As shown, this further ensures the reliability of locking the handle 2, and placing the handle 2 horizontally facilitates the storage and transportation of the punch.

[0036] Specifically, the locking portion 42 is elongated, and in the second state, the extending direction of the locking portion 42 is perpendicular to the extending direction of the second notch 2211, such as... Figure 6 As shown. By designing the extension direction of the locking part 42 and the extension direction of the second notch 2211 as described above, the reliability of locking the handle 2 can be improved through their cooperation.

[0037] In this embodiment, as Figure 2As shown, a torsion spring 24 is installed on the pivot 23 of the handle 2. In the initial state, the handle 2 is inclined along its own length direction, and the connecting end 22 is located at the lower end of the handle 2 while the operating end 21 is located at the upper end of the handle 2. The locking member 4 is a horizontally extending strip-shaped plate. The plate is arranged in a direction perpendicular to the length direction of the handle 2 (left-right direction in this embodiment) and can move back and forth along its own length direction. The locking part 42 and the first notch 41 are arranged side by side along the length direction of the locking member 4. In the initial state, the locking member 4 is located on the connecting end 22 of the handle 2. Rotating the operating end 21 of the handle 2 downwards causes the connecting end 22 of the handle 2 to rotate upwards until the operating end 21 is adjacent to the top surface of the base 1. Moving the locking member 4 causes its locking part 42 to align with the connecting end 22 of the handle 2, and the locking part 42 engages in the second notch 2211 of the connecting end 22. Simultaneously, the torsion spring 24 deforms, causing the connecting end 22 to tend to rotate downwards and return to its original position. This simplifies the structure of the locking member 4, facilitating locking and unlocking of the handle 2 by operating the locking member 4 (i.e., moving the locking member 4 along its length). Furthermore, when the handle 2 is locked, the torsion spring 24 ensures that the handle 2 remains reliably locked, and it automatically returns to its initial state upon unlocking, facilitating drilling operations.

[0038] Preferably, the locking portion 42 is the plate portion of the locking member 4 adjacent to the first notch 41 (e.g., Figure 6 As shown), this simplifies the structure of the locking element 4 and allows it to switch between unlocked and locked states. Specifically, in this embodiment, the end of the connecting end 22 of the handle 2 includes two plates 221 spaced apart in the left-right direction and extending forward and backward respectively. The plate 221 on the right side protrudes outward, and the protrusion 222 has the aforementioned second notch 2211 (as shown). Figure 5 As shown), there are two first notches 41, which are respectively opened at the left and right ends of the locking member 4, so that the corresponding pieces 221 can pass through. In the second state, the second notch 2211 on the right piece 221 engages with the locking part 42, while the left piece 221 abuts against the locking member 4 vertically (at this time, the left piece 221 is lower than the right piece 221).

[0039] Furthermore, such as Figure 3As shown, a bracket 5 is vertically arranged on the top surface of the base 1 along the length of the locking member 4. Each end of the bracket 5 has a mounting opening 51, and the two ends of the locking member 4 are respectively connected to the corresponding mounting openings 51. The locking member 4 can move back and forth relative to each mounting opening 51 along its own length. This allows for both installation of the locking member 4 and movement of the locking member 4 along its own length, enabling switching between unlocked and locked states. Furthermore, a lever 43 protrudes from the locking member 4 for moving it back and forth along its own length. The lever 43 facilitates the user's movement of the locking member 4 along its own length, thus enabling switching between unlocked and locked states. In this embodiment, specifically, the bracket 5 includes support plates 52 arranged opposite each other on the left and right sides. Each support plate 52 extends in the front-back direction, and each support plate 52 has a mounting opening 51 at its upper end. Figure 3 As shown.

[0040] In this embodiment, as Figure 1 and Figure 2 As shown, a housing 11 covers the top surface of the base 1, forming a mounting cavity (not shown). The connecting end 22 of the handle 2 and the locking member 4 are both housed in this mounting cavity. A guide hole 111 extending along the length of the locking member 4 is provided on the housing 11. The lever 43 is fitted into the guide hole 111 and can move back and forth along the length of the guide hole 111. When the lever 43 is located at one end of the guide hole 111, the locking member 4 is in the first state; when the lever 43 is located at the other end of the guide hole 111, the locking member 4 is in the second state. The lever 43 is exposed outside the housing 11 through the guide hole 111, facilitating user operation of the lever 43. The sliding of the lever 43 within the guide hole 111 helps ensure the smooth movement of the locking member 4 along its length, thereby improving the reliability of the unlocking and locking state switching control.

[0041] Furthermore, such as Figure 7 and Figure 8 As shown, the aforementioned lever 43 includes a base plate 431 extending along the length of the locking member 4 and a block 432 protruding from one side of the base plate 431. The block 432 is fitted into a guide hole 111. A mounting post 433 protrudes from the other side of the base plate 431. The mounting post 433 is tensioned and connected to a mounting hole (not shown) on the locking member 4, so that the lever 43 is mounted on the upper surface of the locking member 4. This allows the lever 43 to be securely mounted on the locking member 4 and facilitates the assembly and disassembly of the lever 43 from the locking member 4.
