Technical Field
[0001] The utility model belongs to the technical field of manicure tools, and more specifically, relates to a nail clipper with a locking mechanism. Background Art
[0002] Nail clippers, also known as nail clippers, are personal care products primarily used for trimming fingernails and toenails. They operate using a lever, and most nail clippers are made of metal. Simply applying pressure on the end of the clippers allows the sharp tip to easily cut the nail.
[0003] Traditional nail clippers have no locking mechanism. The nail clippers are always in a loose state with the jaws open, which can easily scratch the hands. They are inconvenient and unsafe to store, and the consumer experience is not good. Nail clippers with locking mechanisms have emerged. The nail clippers with locking mechanisms on the market generally have a more complex structure.
[0004] For example, the Chinese utility model patent with the patent number 202123257460.7 and the utility model name is a rotary lock type locking nail clippers, which includes a left clamp body and a right clamp body, the left clamp body and the right clamp body are cross-mounted near the upper side, and the left clamp body and the right clamp body are movably connected by a connecting mechanism, the right side of the left clamp body is fixedly mounted with a mounting cylinder near the front side, a first mounting hole is opened on the mounting cylinder, and a locking mechanism is provided in the first mounting hole, and the locking mechanism locks the left clamp body and the right clamp body The buckle is fixed, and the locking mechanism includes a rotary disk, a pin shaft, a crescent buckle, a hook, a spring and a first rectangular opening. The rotary disk is installed on the rear side of the mounting cylinder corresponding to the first mounting hole through the pin shaft, and a crescent buckle is provided on the rear side of the rotary disk. The hook is fixed on the left side of the right clamp body corresponding to the crescent buckle, and the hook is mounted on the crescent buckle. The rear side of the rotary disk is provided with a spring, and the spring is movably installed in the first mounting hole. A first rectangular opening is opened on the left clamp body at a position corresponding to the rotary disk.
[0005] The advantages of the above technical solution are that the left and right caliper bodies can be quickly locked together, preventing accidental opening of the left and right caliper bodies, and are convenient and safe to use. However, its disadvantages are that the locking mechanism is relatively complex, with many parts and a small size, resulting in high manufacturing costs, difficult assembly, multiple steps, and high labor costs. Summary of the Invention
[0006] The purpose of the invention of the utility model is to solve the above-mentioned technical problems, and to provide a nail clipper with a locking mechanism which has a simple structure, fewer parts and is easy to assemble.
[0007] The utility model is achieved through the following technical solutions.
[0008] The utility model provides a nail clippers with a locking mechanism, comprising a first pliers body and a second pliers body, the front end of the first pliers body being provided with a first jaw, the front end of the second pliers body being provided with a second jaw, the first pliers body comprising a first pliers head and a first pressure handle, the first pliers head being cross-pivoted to the second pliers body by a pivot, the first jaw being provided at the front end of the first pliers head, the rear end of the first pliers head being provided with a first connecting portion, the front end of the first pressure handle being provided with a second connecting portion, the second connecting portion being slidably connected to the first connecting portion by a sliding mechanism, the first pressure handle being able to slide relative to the first pliers head between a first position and a second position by the sliding mechanism, the first pressure handle being provided with a locking piece on a side facing the second pliers body, the second pliers body being provided with a locking piece cooperating with the locking piece, when the first pressure handle is in the first position, the locking piece disengages from the locking piece, and when the first pressure handle is in the second position, the locking piece cooperates with the locking piece to lock, the first connecting portion being provided with a first limiting portion, and the second connecting portion being provided with a second limiting portion, the first limiting portion and the second limiting portion cooperating to limit the first connecting portion from rotating relative to the second connecting portion.
[0009] In the above technical solution, when the first pressure handle is in the first position, the locking member is disengaged from the locking portion. At this time, operating the first pressure handle can drive the first pliers head to rotate with the pivot as the rotating axis to perform the operation of cutting nails. When the first pressure handle is in the second position, the locking member cooperates with the locking portion to lock, which facilitates the storage of the nail clippers. In addition, the first jaw and the second jaw are in a bite state, and the user cannot touch the first jaw and the second jaw, which is highly safe. By operating the first pressure handle to slide relative to the first pliers head between the first position and the second position, the first pressure handle and the second pliers body can be unlocked and locked. The operation is simple and convenient. In addition, the first pressure handle also has the function of operating the first jaw to bite relative to the second jaw, which optimizes the product structure. The overall product has fewer parts and components, which can reduce the assembly process in the manufacturing process, improve production efficiency, and reduce labor costs.
[0010] Preferably, the sliding mechanism includes an elongated sliding hole provided in the first connecting portion and a sliding member placed in the elongated sliding hole and capable of sliding along the elongated sliding hole, wherein the length extension direction of the elongated sliding hole is the same as the length extension direction of the first pliers head, and the second connecting portion is connected to the sliding member. In this technical solution, the first pressure handle connected to the sliding member can switch between a first position and a second position relative to the first pliers head as the sliding member slides back and forth in the elongated sliding hole, thereby achieving disengagement of the locking member from the locking portion, or locking in cooperation with the locking portion. At the same time, the length of the elongated sliding hole can also limit the travel of the first pressure handle sliding back and forth relative to the first pliers head.
[0011] Preferably, the sliding member is a connecting pin, so that the connecting pin can rotate relative to the second connecting part after being connected to the second connecting part. When the connecting pin slides along the elongated sliding hole, the circumferential surface of the connecting pin is in rolling contact with the hole wall of the elongated sliding hole, which can reduce friction and make sliding smoother.
[0012] Preferably, the first connecting portion is a protruding block extending rearward relative to the rear end of the first pliers head, and the second connecting portion is a connecting arm extending forward relative to the front end of the first pressure handle. There are two connecting arms, which are arranged in parallel at intervals, and the front ends of the two connecting arms are respectively connected to the two ends of the sliding member. In this technical solution, a recess that cooperates with the protruding block is formed between the two connecting arms to facilitate the connection and cooperation between the first pressure handle and the first pliers head. The front ends of the two connecting arms are respectively connected to the two ends of the sliding member, and the sliding member is evenly stressed. When the first pressure plate handle is pushed, the sliding member slides more smoothly relative to the elongated sliding hole.
[0013] Preferably, the first limiting portion is a sliding groove provided on the side of the protrusion, and there are two sliding grooves, which are symmetrically arranged on two opposite sides of the protrusion corresponding to the positions of the elongated sliding hole, and the elongated sliding hole connects the two sliding grooves. The second limiting portion is a ridge provided on the inner side of the connecting arm that can cooperate with the sliding groove. In this technical solution, when the first pressure handle slides relative to the first pliers head, the ridge slides along the sliding groove. Restricted by the groove walls on the upper and lower sides of the sliding groove, the first pressure handle cannot rotate up and down relative to the first pliers head. When the first pressure handle is pressed, the first pliers head can be smoothly driven to rotate about the pivot as the rotating axis, thereby achieving the engagement of the first jaw and the second jaw.
[0014] Preferably, the locking member and the first pressing handle are integrally formed, which can reduce the cost of the mold, reduce the number of assembly steps, and improve assembly efficiency.
[0015] Preferably, the locking member is a hook, which has a simple structure, is easy to form, and has a low manufacturing cost.
[0016] Preferably, the locking portion is a slot that cooperates with the hook. In this way, the structure is simple and the slot and the hook are easy to cooperate with each other.
[0017] Preferably, an elastic member is provided between the first pliers head and the second pliers body to provide elastic force for the first jaw to open relative to the second jaw. In this way, after the pressing force of the first pressure handle is released, the first jaw can automatically open relative to the second jaw without manual operation, reducing the operating steps and providing a better user experience.
[0018] Preferably, the elastic member is a torsion spring, which is sleeved on the pivot, with one end of the torsion spring abutting against the inner side of the first pliers head and the other end of the torsion spring abutting against the inner side of the second pliers body. In this way, the structure is simple and easy to assemble.
[0019] The beneficial effect of the present invention is that the locking member and the first pressing handle are an integrated structure, and the first pressing handle and the second pliers body can be unlocked and locked by operating the first pressing handle to slide relative to the first pliers head between the first position and the second position, which is easy to operate; the overall structure of the product is simple, the number of parts is small, the assembly process is small, the assembly efficiency is high, and the production cost can be effectively reduced.

The locking portion 31 is a card slot that cooperates with the hook. When the first pressure handle 2 is in the first position, the locking member 22 is disengaged from the locking portion 31, and the first pressure handle 2 can be opened relative to the second pliers body 3. When the first pressure handle 2 is in the second position, the locking member 22 cooperates with the locking portion 31 to lock, and the first pressure handle 2 cannot be opened relative to the second pliers body 3, and the first jaw 101 and the second jaw 301 are in a bite state, which is convenient for storing the nail clippers. When the first pressure handle 2 is in the first position, in order to achieve the ability to drive the first pliers head 1 to rotate with the pivot 4 as the rotating axis when pressing the first pressure handle 2, the first connecting portion 11 is also provided with a first limiting portion, and the second connecting portion 21 is also provided with a second limiting portion. The first limiting portion and the second limiting portion cooperate to limit the first connecting portion 11 from rotating relative to the second connecting portion 21.
[0033] like Figure 6 and Figure 7 As shown, in this embodiment, the first connecting portion 11 is a protrusion extending backward relative to the rear end of the first pliers 1, and the second connecting portion 21 is a connecting arm extending forward relative to the front end of the first pressure handle 2. There are two connecting arms, and the two connecting arms are arranged in parallel at intervals, and a recess 23 that cooperates with the protrusion is formed between the two connecting arms.
[0034] like Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the sliding mechanism includes an elongated sliding hole 111 provided in the protrusion and a sliding member 112 placed in the elongated sliding hole 111 and capable of sliding along the elongated sliding hole 111. The elongated sliding hole 111 passes through the front and rear sides of the protrusion and the length extension direction of the elongated sliding hole 111 is the same as the length extension direction of the first pliers 1.

When the first pressing handle 2 is pressed, the first pliers head 1 can be smoothly driven to rotate with the pivot 4 as the rotating axis, thereby realizing the engagement of the first jaw and the second jaw.
[0036] The working principle of this utility model is as follows:
[0037] like Figure 4As shown, at this time, the first pressure handle 2 is in the second position, and the locking member 22 and the locking portion 31 are in a locked state. When it is necessary to use the first jaw 101 and the second jaw 301 to cut nails, the first pressure handle 2 is pushed leftward from the second position to a position. At this time, the locking member 22 is disengaged from the locking portion 31, and the first pressure handle 2 can be opened upward relative to the second jaw body 3. The first pliers head 1 can be driven by the first pressure handle 2 to rotate with the pivot 4 as the axis under the constraints of the first limiting portion and the second limiting portion. In this state, operating the first pressure handle 2 to open upward relative to the second jaw body 3 can make the first jaw 101 open relative to the second jaw 301. Operating the first pressure handle 2 is closed downwardly relative to the second jaw body 3, so that the first jaw 101 can be engaged with the second jaw 301; when nail clipping is not required, the first pressure handle 2 is pressed and pushed rightward from the first position to the second position. At this time, the locking member 22 cooperates with the locking portion 31 to lock, and the first pressure handle 2 cannot be opened upward relative to the second jaw body 3, so that the nail clippers are conveniently stored. The first jaw 101 and the second jaw 301 are in an engaged state, and the user will not touch the first jaw 101 and the second jaw 301, which is safe.
[0038] Example 2
[0039] The structure of this embodiment is similar to that of embodiment 1, except that Figure 1 and Figure 4 As shown, an elastic member 5 is provided between the first pliers head 1 and the second pliers body 3 to provide elastic force for the first jaw 101 to open relative to the second jaw 301. The elastic member 5 is a torsion spring, which is mounted on the pivot 4. One end of the torsion spring abuts against the inner side surface of the first pliers head 1, and the other end of the torsion spring abuts against the inner side surface of the second pliers body 3.
[0040] In this way, after the pressing force of the first pressing handle 2 is released, the first jaw 101 can automatically open relative to the second jaw 301 without manual operation, thus reducing the number of operating steps and providing a better user experience.
[0041] Example 3
[0042] The structure of this embodiment is similar to that of embodiment 2, except that Figure 8 As shown, the specific structures of the first limiting part and the second limiting part are different. In this embodiment, the first limiting part is a slot 12 provided at the rear end of the first pliers 1, and the second limiting part is an insert block 212 provided at the front end of the second connecting part 21. When the first pressure handle 2 is in the first position, the insert block 212 is inserted into the slot 12 for cooperation. At this time, operating the first pressure plate 2 can drive the first pliers 1 to rotate with the pivot 4 as the axis.
[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
