Description

Technical Field

[0001] This utility model belongs to the field of nail trimming tool technology, and more specifically, it relates to a nail clipper with a push-pull lock. Background Technology

[0002] Nail clippers, also known as nail nippers or nail pliers, were invented by Americans in the 1930s. They are a personal care product mainly used for trimming nails and toenails. They operate using the lever principle. Most nail clippers are made of metal. Users only need to apply force to press the end of the clippers to easily cut the nails through the sharp tip.

[0003] There are many styles of nail clippers available nowadays. Some are larger and come with a nail file, while others are smaller and lighter and can be used as keychains. Some even have a locking device to keep the jaws closed.

[0004] For example, Chinese utility model patent with patent number 202222751161.1 and invention title "A Nail Clipper with Push-Pull Locking Mechanism" includes a clipper body. The clipper body is composed of clipper handle one and clipper handle two intersecting in an X-shape. Clipper heads are respectively provided at the proximal ends of the intersection of clipper handle one and clipper handle two. Clipper handle one and clipper handle two are hinged at the intersection. A spring element is provided on the hinge shaft to separate the two clipper heads. A push-pull locking mechanism is provided at the distal end of the intersection of clipper handle one and clipper handle two. The push-pull locking mechanism includes a locking hook and a locking buckle. The locking hook is fixed on clipper handle one, and the locking buckle is movably provided on clipper handle two and slidably connected to clipper handle two. When the clipper heads are engaged, the locking buckle is slid forward to lock the locking buckle with the locking hook, and the locking buckle is slid backward to separate the locking buckle from the locking hook.

[0005] Although the above technical solution solves the technical problem of maintaining the closed state of the jaws, its push-pull locking mechanism is located at the far end of the intersection of jaw one and jaw two. The locking hook is fixed to jaw one, which means that the length of the locking hook needs to be relatively long to hook the lock. If the locking hook is too long, it will reduce the strength of the locking hook and make it easy to break. The structure of the lock is also too complicated, with many assembly steps, high labor costs, and high production costs. Summary of the Invention

[0006] The purpose of this invention is to solve the aforementioned technical problems and to provide a nail clipper with a push-pull lock that has a simple structure and relatively low production cost.

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

[0008] This utility model provides a nail clipper with a push-pull lock, including a first clamp body and a second clamp body pivotally connected together in an X-shape by a pivot pin. The first clamp body has a first pivot part on its side for pivoting with the pivot pin, and the second clamp body has a second pivot part on its side for pivoting with the pivot pin. The pivot pin passes through the first pivot part and the second pivot part to pivotally connect the first clamp body and the second clamp body together. The rear end face of the first pivot part has a socket. The second clamp body has a push-pull lock mechanism at the position corresponding to the socket. The push-pull lock mechanism is configured to slide back and forth along the second clamp body and has a first position for inserting into the socket and a second position for disengaging from the socket. When the push-pull lock mechanism is in the first position, the push-pull lock mechanism cooperates with the socket to maintain the front end of the first clamp body and the front end of the second clamp body in a relatively closed state. When the push-pull lock mechanism is in the second position, the front end of the first clamp body can open relative to the front end of the second clamp body.

[0009] The above technical solution allows the right thumb to control the push-pull locking mechanism while holding the nail clippers with one hand. When the front ends of the first and second clamping bodies are closed relative to each other, the right thumb operates the push-pull locking mechanism to slide forward relative to the second clamping body until the front end of the push-pull locking mechanism is inserted into the socket. The push-pull locking mechanism then engages with the socket to maintain the relative closed state of the front ends of the first and second clamping bodies. In this way, when the nail clippers are not in use, the user will not touch the blades of the first and second clamping bodies, ensuring good safety. When it is necessary to use the nail clippers to trim nails, simply slide the push-pull locking mechanism backward relative to the second clamping body while the front ends of the first and second clamping bodies are closed relative to each other with the right thumb until the front end of the push-pull locking mechanism disengages from the socket. The front end of the first clamping body will then open and move closer to the front end of the second clamping body, thus completing the nail trimming operation.

[0010] Preferably, the second clamp body has a sliding seat at the rear of the insertion port. The sliding seat has a first sliding groove running forward and backward. The push-pull lock mechanism includes a pushing member, a sliding member, and a clamping member. The pushing member is placed on the outer side of the sliding seat, and its front end can be inserted into the insertion port. The outer end of the sliding member is connected and fixed to the inner side of the pushing member. The sliding member is placed in the first sliding groove, and its inner end extends to the inner side of the sliding seat. The inner end of the sliding member is connected to the clamping member. The clamping member abuts against the inner side of the sliding seat, preventing the sliding member from disengaging from the first sliding groove towards the outer side of the sliding seat. In this technical solution, when the pushing member moves forward and backward, the sliding member cooperates accurately with the first sliding groove and slides smoothly. The clamping member can prevent the sliding member from disengaging from the first sliding groove during the forward and backward sliding process relative to the sliding seat. The push-pull lock mechanism operates stably and reliably.

[0011] Preferably, the inner end of the sliding member has a lug extending from both the front and rear sides. The clamping member is a compression spring, which is fitted onto the sliding member with its inner end abutting against the lug and its outer end abutting against the inner side of the sliding seat. In this technical solution, by providing lugs at the inner end of the sliding member, the compression spring can be easily fixed. The compression spring can prevent the sliding member from disengaging from the first slide groove, and the spring force of the compression spring can also press the pushing member against the outer side of the sliding seat, increasing the friction when the pushing member slides relative to the sliding seat, preventing the pushing member from sliding accidentally under gravity, and improving the reliability of the push-pull lock mechanism.

[0012] Preferably, the compression spring is a frustoconical shape with a small end and a large end, the outer diameter of the small end being smaller than the outer diameter of the large end, the inner end of the compression spring being the small end, and the outer end of the compression spring being the large end. In this technical solution, by having the small end of the compression spring abut against the lug, the length of the lug can be reduced, saving material and preventing the lug from becoming too long and reducing its strength. By having the large end of the compression spring abut against the inner surface of the sliding seat, the contact area can be increased, and the force is more evenly distributed when the end face of the large end of the compression spring rubs against the inner surface of the sliding seat, resulting in better stability of the push-pull lock mechanism during sliding. In addition, it also facilitates the installation of the compression spring. Simply compress the compression spring first, then tilt it at a certain angle relative to the sliding part, allowing one lug to pass through the small end first, then the other lug to pass through the small end, and finally return the compression spring to its original position to complete the installation.

[0013] Preferably, the outer surface of the pusher is provided with anti-slip stripes. This prevents slippage when pushing the pusher due to sweat or moisture on the thumb.

[0014] Preferably, the pusher, the slider, and the lug are integrally formed. This simplifies the push-pull lock mechanism and makes it easier to manufacture and assemble.

[0015] Preferably, the sliding seat is a hollowed-out plate-shaped body that protrudes vertically upward relative to the inner side of the second clamp body, and the hollowed-out portion of the plate-shaped body is the first sliding groove. In this technical solution, the hollowed-out plate-shaped body can be integrally formed with the second clamp body, which makes processing easier and reduces assembly steps.

[0016] Preferably, the top outer side of the plate-like body is provided with an outwardly extending flange. The flange, the outer side of the block-like body, and the inner side of the second clamping body together form a second sliding groove. The second sliding groove communicates with the first sliding groove, and the pushing member is placed in the second sliding groove. In this way, the stability of the pushing member during the back-and-forth sliding process can be further improved by cooperating with the second sliding groove.

[0017] Preferably, both the inner sides of the first and second pivot portions are provided with mounting grooves, and the mounting grooves are provided with elastic elements that provide elastic force for the front ends of the first and second clamping bodies to open relative to each other. Thus, after the nail-cutting action is completed and the operating force on the first and second clamping bodies is released, the front ends of the first and second clamping bodies can automatically open under the action of the elastic elements to facilitate the next biting operation.

[0018] Preferably, the elastic element is a V-shaped spring sheet. In this technical solution, the V-shaped spring sheet has a larger contact area with the groove wall of the mounting groove, and can provide greater pressure under the same elastic force, which is beneficial for the front ends of the two clamps to open relative to each other.

[0019] The beneficial effects of this utility model are that the locking and unlocking of the first and second clamps can be achieved by pushing the pusher back and forth, which is simple and convenient to operate; the pusher, the sliding member and the lug are integrated into one structure, which can be assembled and fixed with the sliding seat with the compression spring, making assembly easy; the pusher cooperates with the second slide groove, the sliding member cooperates with the first slide groove, and the compression spring makes the pusher abut against the second slide groove, so the pusher slides stably and the locking effect is reliable.

[0027] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0028] Example 1

[0029] This utility model provides a nail clipper with a push-pull lock, such as Figure 1 , Figure 2 and Figure 3 As shown, the device includes a first clamp body 1 and a second clamp body 2 pivotally connected together in an X-shape by a pivot pin 3. The first clamp body 1 has a first pivot part 11 on its side for pivoting with the pivot pin 3, and the second clamp body 2 has a second pivot part 21 on its side for pivoting with the pivot pin 3. The pivot pin 3 passes through the first pivot part 11 and the second pivot part 21 to pivotally connect the first clamp body 1 and the second clamp body 2 together. The rear end face of the first pivot part 11 has a socket 111. The second clamp body 2 has a push-pull locking mechanism 4 at the position corresponding to the socket 111. The push-pull locking mechanism 4 is configured to slide back and forth along the second clamp body 2 and has a first position for inserting into the socket 111 and a second position for disengaging from the socket 111. When the push-pull locking mechanism 4 is in the first position, the push-pull locking mechanism 4 cooperates with the socket 111 to maintain the front end of the first clamp body 1 and the front end of the second clamp body 2 in a relatively closed state. When the push-pull locking mechanism 4 is in the second position, the front end of the first clamp body 1 can open relative to the front end of the second clamp body 2.

[0030] like Figure 3 and Figure 4As shown, in this embodiment, the second clamp body 2 is provided with a sliding seat 22 at the rear of the insertion port 111, and the sliding seat 22 is provided with a first sliding groove 23 running back and forth. In this embodiment, the push-pull lock mechanism 4 includes a pusher 41, a sliding member 42, and a clamping member 43. The pusher 41 is placed on the outer side of the sliding seat 22 and the front end of the pusher 41 can be inserted into the insertion port 111. The outer end of the sliding member 42 is connected and fixed to the inner side of the pusher 41. The sliding member 42 is placed in the first sliding groove 23 and the inner end of the sliding member 42 extends to the inner side of the sliding seat 22. The inner end of the sliding member 42 is connected to the clamping member 43. The clamping member 43 abuts against the inner side of the sliding seat 22, which can restrict the sliding member 42 from disengaging from the first sliding groove 23 in the direction of the outer side of the sliding seat 22.

[0031] like Figure 4 As shown, as a further improvement, a lug 421 extends from the front and rear sides of the inner end of the slider 42. The clamping member 43 is a compression spring. The compression spring is fitted on the slider 42 and the inner end of the compression spring abuts against the lug 43. The outer end of the compression spring abuts against the inner side of the sliding seat 22. In this embodiment, the pusher 41, the slider 42, and the lug 421 are integrally formed. Anti-slip stripes 411 are also provided on the outer side of the pusher 41. The anti-slip stripes 411 can prevent slippage when pushing the pusher 41 due to sweat or moisture on the thumb.

[0032] like Figure 5 As shown, as a further improvement, the sliding seat 22 is a hollowed-out plate-shaped body that protrudes vertically upward relative to the inner side of the second clamp 2. The hollowed-out portion of the plate-shaped body is the first sliding groove 23. The top outer side of the plate-shaped body is provided with an outwardly extending flange 221. The flange 221, the outer side of the plate-shaped body, and the inner side of the second clamp 2 together form a second sliding groove. The second sliding groove is connected to the first sliding groove 23, and the pushing member 41 is placed in the second sliding groove. By cooperating with the second sliding groove and the pushing member 41, the stability of the pushing member 41 during the back-and-forth sliding process can be further improved.

[0033] The working principle of this utility model is as follows:

[0034] When nail clippers are not needed, close the front ends of the first clamp 1 and the second clamp 2 relative to each other, grasp the first clamp 1 and the second clamp 2 with your right hand, and use your right thumb to push the pusher 41 forward relative to the second clamp 2 until the front end of the pusher 41 is inserted into the socket 111. The pusher 41 will then cooperate with the socket 111 to maintain the front ends of the first clamp 1 and the second clamp 2 in a relatively closed state. In this way, when the nail clippers are not in use, the user will not touch the blades of the first clamp 1 and the second clamp 2, which is safe. When nail clippers are needed, simply close the front ends of the first clamp 1 and the second clamp 2 relative to each other, and push the pusher 41 backward relative to the second clamp 2 with your right thumb until the front end of the pusher 41 is disengaged from the socket 111. The front end of the first clamp 1 will then open and move closer to the front end of the second clamp 2, thereby completing the nail clipping operation.

[0035] Example 2

[0036] The structure of this embodiment is similar to that of Embodiment 1, except that, as follows: Figure 4 As shown, the compression spring is a frustum-shaped structure with a small end and a large end. The outer diameter of the small end is smaller than the outer diameter of the large end. The inner end of the compression spring is the small end, and the outer end of the compression spring is the large end.

[0037] The small end of the compression spring abuts against the lug 421, which reduces the length of the lug 421, saving material and preventing the lug 421 from becoming too long and reducing its strength. The large end of the compression spring abuts against the inner surface of the sliding seat 22, increasing the contact area. This results in more even force distribution when the large end of the compression spring rubs against the inner surface of the sliding seat 22, improving the stability of the push-pull lock mechanism 4 during sliding. Furthermore, it facilitates the installation of the compression spring. Simply compress the spring, then tilt it at a certain angle relative to the sliding member 42, allowing one lug 421 to pass through the small end first, then the other lug 421, and finally return the spring to its original position to complete the installation.

[0038] Example 3

[0039] The structure of this embodiment is similar to that of embodiment 2, except that, as follows: Figure 3 As shown, mounting grooves 112 are provided on the inner side of the first pivot 11 and the inner side of the second pivot 21. The mounting grooves 112 are provided with elastic elements 5 that provide elastic force for the front ends of the first clamp 1 and the front ends of the second clamp 2 to open relative to each other. In this embodiment, the elastic element 5 is preferably a V-shaped spring sheet. The V-shaped spring sheet has a larger contact area with the groove wall of the mounting groove 112. Under the same elastic force of the elastic element 5, the V-shaped spring sheet can provide greater pressure, which is beneficial for the front ends of the two clamps to open relative to each other.

[0040] 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. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
