Description

Technical Field

[0001] This utility model belongs to the field of nail care tool technology, and more specifically, it relates to a locking nail clipper. Background Technology

[0002] Nail clippers, also known as nail razors, are personal care products primarily used for trimming fingernails and toenails. They operate using the lever principle; most nail clippers are made of metal, and users simply apply pressure to the end of the clippers to easily cut nails through the sharp tip.

[0003] Traditional nail clippers lack a locking mechanism, leaving them constantly loose with the jaws open, which can easily scratch hands. They are also inconvenient and unsafe to store, resulting in a poor consumer experience. Nail clippers with a locking mechanism have emerged to address this issue, although the placement of the locking mechanism affects ease of operation.

[0004] For example, Chinese utility model patent with patent number 202320400923.0 and invention title "A Novel Locking Nail Clipper" includes an upper clipper handle and a lower clipper handle. The upper clipper handle is rotatably connected to the lower clipper handle via a nail. A V-shaped spring is provided on the inner side of the front end of the upper clipper handle, and the V-shaped spring abuts against both the upper and lower clipper handles. A locking block is provided on the inner side of the tail end of the lower clipper handle, and a locking buckle is provided on the inner side of the tail end of the upper clipper handle. The locking block engages with the locking buckle, and a spring is sleeved on the outer side of the locking buckle.

[0005] While the nail clippers described in the aforementioned patent are safe, their locking mechanism is located at the end of the handle, making them inconvenient to operate. The structure is also relatively complex, leaving room for improvement. Summary of the Invention

[0006] The purpose of this invention is to solve the above-mentioned technical problems and to provide a locking nail clipper that is simple in structure and easy to operate.

[0007] This utility model is achieved through the following technical solution.

[0008] This utility model provides a locking nail clipper, including a first clamp body and a second clamp body pivotally connected together by a pivot pin. The front end of the first clamp body is provided with a first cutting edge, and the front end of the second clamp body is provided with a second cutting edge. The first cutting edge and the second cutting edge are arranged opposite each other and can mesh with each other. The first clamp body is provided with a rotating member at the inner position behind the pivot pin, and the second clamp body is provided with a latching member at the inner position behind the pivot pin, which cooperates with the rotating member. The rotating member has a first position and a second position. When the rotating member is in the first position, the rotating member is engaged with the latching member to maintain the meshing state of the first cutting edge and the second cutting edge. When the rotating member is in the second position, the rotating member is disengaged from the latching member. The first clamp body and the second clamp body are connected by an elastic member that provides elastic force for the first clamp body to open relative to the second clamp body.

[0009] In the above technical solution, the rotating component is cleverly designed and positioned at the front end of the first clamp body, allowing the user to easily operate it with their thumb. By simply rotating this rotating component, the user can switch between the first and second positions. When the rotating component is in the first position, it engages tightly with the locking component, forming a secure locking state. This prevents the first and second cutting edges from opening relative to each other, maintaining a meshing state. This design greatly improves safety during use because, in this state, the user cannot directly contact the cutting edges, effectively preventing accidental injury.

[0010] Preferably, the first clamp body has a first recessed groove on its outer side behind the pivot pin. The top of the rotating component is placed in the first recessed groove and pivotally connected to the first clamp body via a connecting pin. The lower inner side of the rotating component has a locking slot. When the rotating component is in the first position, the locking slot can engage with a locking component. When the rotating component is in the second position, the rear side of the rotating component abuts against the rear wall of the first recessed groove. In this technical solution, the main purpose of setting the first recessed groove is to keep the outer surface of the rotating component as level as possible with the outer side of the first clamp body. This effectively reduces visual abruptness, making the overall structure look more harmonious and aesthetically pleasing. In addition, the rear wall of the first recessed groove can limit and control the rotation angle of the rotating component. This design not only improves the stability and safety of the equipment but also ensures the accuracy and reliability of the rotating component during operation, thereby improving the performance of the entire structure.

[0011] Preferably, the outer surface of the rotating component has a third recess at the position corresponding to the connecting nail. A compression spring is installed in the third recess, and the compression spring is fitted onto the nail body of the connecting nail. The bottom end of the compression spring abuts against the bottom of the third recess, and the top end of the compression spring abuts against the inner side of the nail head of the connecting nail. In this technical solution, if the rotating component is too tightly tightened, it will be difficult to rotate freely. This will not only significantly affect the efficiency of the equipment, but may also cause unnecessary wear and damage to the mechanical structure in the long run. On the other hand, if the rotating component is too loose, it will not be able to tightly engage with the locking component, resulting in an unreliable locking mechanism, which in turn affects the overall stability and safety. To solve this problem, a compression spring is used to effectively balance the tightness between the rotating component and the first clamp body. This design ensures that the rotating component can rotate flexibly while ensuring a tight engagement with the locking component, thereby greatly improving the performance and reliability of the equipment.

[0012] Preferably, the outer side of the rotating component is provided with anti-slip stripes. In this way, the user can effectively avoid slippage caused by sweaty hands when operating the rotating component, thereby significantly improving the stability during operation.

[0013] Preferably, the second clamp body has a second recessed groove on its outer side behind the pivot pin. The depth of the second recessed groove is the same as the depth of the first recessed groove. The locking member is disposed in the second recessed groove and protrudes upward relative to the bottom of the groove. In this technical solution, the depth of the second recessed groove is consistent with the depth of the first recessed groove. This design ensures that the rotating part can smoothly and unobstructedly rotate into the second recessed groove. In addition, the locking member is designed to protrude upward relative to the bottom of the second recessed groove. As the rotating part rotates to the first position, the locking member will gradually enter and embed into the locking slot. As the rotation continues, the locking member will gradually tighten, thereby ensuring the stability and safety of the rotating part during the rotation process.

[0014] Preferably, the front end of the latching member is connected to the wall of the second settling tank, while the rear end of the latching member is separated from the wall of the second settling tank. This design improves the structural strength of the latching member and ensures sufficient travel space during use to tightly engage with the locking portion of the rotating component. Furthermore, the front wall of the second settling tank effectively limits the movement of the rotating component, thus ensuring the stability and reliability of the entire mechanical device.

[0015] Preferably, the thickness of the rear end of the latching component is less than the thickness of the front end. With this design, as the rotating component continues to rotate and move towards the first position, the latching component gradually comes into close contact with the inner wall of the bayonet and eventually abuts against it, thus ensuring the stability and reliability of the connection.

[0016] Preferably, the side of the fastener has several raised ridges. This design ensures that a suitable tension is generated between the fastener and the inner wall of the latch, making the fastener more smoothly clamped to the latch and easier to disengage when needed, effectively preventing jamming.

[0017] Preferably, the inner sides of the first clamp body and the inner sides of the second clamp body are provided with mounting grooves at the positions of the corresponding pivot pins, and the elastic element is installed in the mounting grooves. With this design, the elastic element is cleverly hidden between the first and second clamp bodies, making the overall structure more compact and aesthetically pleasing.

[0018] Preferably, the mounting groove is an annular groove, which communicates with a positioning groove. The elastic element is an annular torsion spring, which is fitted onto the pivot pin, with one end of the annular torsion spring placed in the positioning groove of the first clamp and the other end placed in the positioning groove of the second clamp. This design secures the end of the annular torsion spring in a specific positioning groove. This ensures precise alignment of the structure during the elastic deformation process that provides the restoring force, effectively preventing misalignment and significantly improving the stability of the annular torsion spring, making it more reliable in various applications.

[0019] The advantages of this invention are that the rotating component is positioned at the front end of the first clamp body, ensuring convenient operation with the thumb during actual use. A simple rotating motion allows for easy switching between the first and second positions, quickly achieving the locking and unlocking functions between the first and second clamp bodies. Furthermore, the elastic component provides necessary pre-tension between the first and second clamp bodies, making it easier to open the first clamp body relative to the second and providing additional assistance for the engagement of the rotating component and the latching component, ensuring a smooth and efficient operation.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0031] Example 1

[0032] This utility model provides a nail clipper with a locking mechanism, such as... Figure 1 and Figure 2As shown, the clamps include a first clamp body 1 and a second clamp body 2, which are pivotally connected together by a pivot pin 3. The front end of the first clamp body 1 is provided with a first cutting edge 11, and the front end of the second clamp body 2 is provided with a second cutting edge 21. These two cutting edges are arranged opposite to each other and can mesh with each other, so that the clamps can firmly grip objects when in use. A rotating member 5 is provided on the inner side of the first clamp body 1 near the pivot pin 3, and a latching member 6 that cooperates with the rotating member 5 is provided on the inner side of the second clamp body 2 near the pivot pin 3. The rotating member 5 has a first position and a second position, and can rotate within the range of the first position and the second position. When the rotating member 5 is in the first position, the rotating member 5 can engage with the latching member 6 to maintain the meshing state of the first cutting edge 11 and the second cutting edge 21. When the rotating member 5 is in the second position, the rotating member 5 can disengage from the latching member 6, and the first clamp body 1 and the second clamp body 2 can open relative to each other. The first clamp 1 and the second clamp 2 are also connected to an elastic element (not shown in the figure) that provides elastic force for the first clamp 1 to open relative to the second clamp 2, so that when the rotating part 5 is in the second position, the first clamp 1 and the second clamp 2 can automatically open relative to each other to prepare for the next trimming operation.

[0033] like Figure 3 and Figure 4 As shown, in this embodiment, the first clamp body 1 has a first recessed groove 12 on its outer side behind the pivot pin 3. The top of the rotating member 5 is placed in the first recessed groove 12 and pivotally connected to the first clamp body 1 via the connecting pin 4. The lower part of the rotating member 5 protrudes from the first handle body 1 and extends towards the second handle body 2. The lower inner side of the rotating member 5 has a locking slot 51, and the outer side has anti-slip stripes 52. When the rotating member 5 is in the first position, the locking slot 51 can engage with the buckle 6 to lock. When the rotating member 5 is in the second position, the rear side of the rotating member 5 abuts against the rear wall of the first recessed groove 12.

[0034] like Figure 5 As shown, in this embodiment, the second clamp body 2 is provided with a second recess 22 on the outer side behind the pivot pin 3. The depth of the second recess 22 is set to be the same as the depth of the first recess 12. The fastening member 6 is provided in the second recess 22 and protrudes upward relative to the bottom of the second recess 22. Moreover, the front end of the fastening member 6 is connected to the wall of the second recess 22, and the rear end is separated from the wall of the second recess 22.

[0035] like Figure 5 As shown, as a further improvement, the thickness of the rear end of the latching member 6 is set to be less than the thickness of the front end of the latching member 6. With this design, as the rotating member 5 continues to rotate and move towards the first position, the latching member 6 will gradually come into close contact with the inner wall of the bayonet 51 and eventually abut against it, thereby ensuring the stability and reliability of the connection.

[0036] like Figure 6As shown, as a further improvement, the elastic element can be various types of springs, such as coil springs, leaf springs, or other forms of elastic elements. Its material and size can be selected and adjusted according to actual application requirements. In this embodiment, a ring torsion spring is selected. More specifically, the ring torsion spring is installed on the inner side of the first clamp 1 and the inner side of the second clamp 2, and mounting grooves 8 are provided at the corresponding pivot pins 3. The mounting grooves 8 are annular grooves, which are connected to positioning grooves 81. The ring torsion spring is fitted on the pivot pins 3, and one end of the ring torsion spring is placed in the positioning groove 81 of the first clamp 1, and the other end is placed in the positioning groove 81 of the second clamp 2. The end of the ring torsion spring is fixed in a specific positioning groove. In this way, during the elastic deformation process of the ring torsion spring to provide the restoring force, it can ensure the precise alignment of its structure, thereby effectively avoiding the occurrence of misalignment, significantly improving the stability of the ring torsion spring, and making it more reliable in various applications.

[0037] Example 2

[0038] The structure of this embodiment is similar to that of embodiment 1, except that, as follows: Figure 3 As shown, the outer side of the rotating part 5 is provided with a third recess at the position corresponding to the connecting nail 4. A compression spring 7 is provided in the third recess. The compression spring 7 is fitted onto the nail body of the connecting nail 4. The bottom end of the compression spring 7 abuts against the bottom of the third recess, and the top end of the compression spring 7 abuts against the inner side of the nail head of the connecting nail 4.

[0039] By setting the compression spring 7, the tightness between the rotating part 5 and the first clamp body 1 is effectively balanced. This design ensures that the rotating part 5 can rotate flexibly and that it can be tightly matched with the buckle 6, thereby greatly improving the performance and reliability of the equipment.

[0040] Example 3

[0041] The structure of this embodiment is similar to that of embodiment 2, except that, as follows: Figure 5 As shown, the fastener 6 has several protruding ribs 61 on its side that can abut against the inner wall of the latch 51. The protruding ribs 61 can ensure that a moderate tension is generated between the fastener 6 and the inner wall of the latch 51, so that the fastener 6 can be more smoothly fastened to the latch 51, and can also be more easily disengaged when needed, effectively avoiding jamming.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
