Description

Technical Field

[0001] This utility model relates to the field of nail clippers, and in particular to a nail clipper with a locking structure. Background Technology

[0002] Nail clippers, also known as nail scissors or nail trimmers, are essential items in daily life. Long nails are prone to bacterial growth, so regular trimming is necessary to maintain nail health, and nail clippers help people trim their nails quickly. A common nail clipper structure typically includes two pressable arms connected by a pin for rotation. Pressing the arms engages the jaws, and releasing them releases the jaws. However, this type of nail clipper lacks a locking mechanism; in the normal operating state, the jaws are separated, making it easy to cut oneself, and it's also inconvenient and unsafe to store.

[0003] Currently, nail clippers with locking mechanisms have appeared on the market. These mechanisms are usually located on the two clipper arms, locking the two arms to engage their jaws. The locking mechanism includes a hook and a latch. The hook is fixed to the handle of one clipper arm, and the latch is movably located on the handle of the other clipper arm. The latch engages with the hook to achieve locking. However, when using nail clippers normally, users often need to press the handle. Placing the locking mechanism on the handle would affect normal operation and could easily lead to accidental activation. Furthermore, nail clippers have many parts and are not aesthetically pleasing. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a nail clipper with a locking structure. This avoids the problems of the locking structure affecting operation and being prone to accidental activation in the prior art. Moreover, it has a simple structure, is easy to operate, has few parts, and is low in cost.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a nail clipper with a locking structure includes two rotatably connected arms, one end of each arm is provided with opposing jaws, and an elastic element is fitted between the two arms to drive the two jaws to be in a separated state. A locking structure is provided on the opposite side of the two arms. The locking structure includes a latch, a first locking part and a second locking part. The first locking part is provided on one arm and the second locking part is provided on the other arm, and the two are arranged opposite to each other along the rotation axis of the arms. The latch extends along the rotation axis of the arms and one end is slidably connected to the first locking part. The second locking part is provided with a snap-fit ​​part. When the two jaws are in a biting state, the latch slides relative to the first locking part so that its other end engages or disengages with the snap-fit ​​part to achieve locking or unlocking.

[0006] Furthermore, the latch is closer to the jaws when unlocked than when locked.

[0007] Furthermore, the second locking part is provided with a first slide, one end of which is a closed end and the other end is an open end. The first slide is the latching part. When the two jaws are in the biting state, locking is achieved by sliding the other end of the latch into the first slide from the open end of the first slide. When the two jaws are in the biting state, the first slide is located on the extension line of the line connecting the rotation axis of the jaws and the jaw arms.

[0008] Furthermore, the second locking part is also provided with a second slide extending along the swing direction of one of the clamp arms relative to the other clamp arm, one end of the second slide is connected to the open end of the first slide, and the other end extends toward one of the clamp arms.

[0009] Furthermore, a notch is provided at the other end of the second slide.

[0010] Furthermore, the first locking part is provided with an elongated hole, one end of the latch is slidably connected to the elongated hole, and when the two jaws are engaged, the extension direction of the elongated hole is consistent with the extension direction of the first slide.

[0011] Furthermore, the slide is a groove or a hole.

[0012] Furthermore, the first locking part is provided with an elongated hole, one end of the latch is provided with an operating protrusion, and the other end is provided with a snap-fit ​​protrusion. The diameter of the snap-fit ​​protrusion and the operating protrusion is greater than the width of the elongated hole. The latch passes through the elongated hole. The operating protrusion is located on the side of the first locking part away from the second locking part, and the snap-fit ​​protrusion is located on the side of the first locking part facing the second locking part.

[0013] Furthermore, the buckle outer sleeve is provided with a silicone ring, which fits between the first locking part and one end of the buckle.

[0014] Furthermore, the first locking part and the second locking part are in the form of plates.

[0034] In this invention, the terms "first" and "second" are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be interpreted as indicating or implying relative importance.

[0035] Furthermore, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "provided with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0036] Please see Figures 1-9 As shown, this utility model discloses a nail clipper with a locking structure, comprising two rotatable arms connected to each other. Specifically, the two arms are rotatably connected via a pivot 6. Each arm has opposing jaws 13 at one end, and an elastic element 7 engages between the arms to keep the jaws 13 in a separated state. A locking structure is provided on the opposite sides of the arms, comprising a latch 4, a first locking part 2, and a second locking part 3. The first locking part 2 is located on one arm, and the second locking part 3 is located on the other arm, with the two positioned opposite each other along the rotation axis of the arms. The latch 4 extends along the rotation axis of the arms, and one end is slidably connected to the first locking part 2. The second locking part 3 has a latching part. When the jaws 13 are engaged, the latch 4 slides relative to the first locking part 2, causing its other end to engage or disengage with the latching part, thus locking or unlocking. Specifically, the rotation axis of the arms is the central axis of the pivot 6. Figure 2 As shown by the center line. For ease of distinction, one of the clamp arms is named the first clamp arm 11 and the other clamp arm is named the second clamp arm 12. The first locking part 2 is provided on the first clamp arm 11 and the second locking part 3 is provided on the second clamp arm 12, but it is not limited to this. The first locking part 2 can also be provided on the second clamp arm 12 and the second locking part 3 can also be provided on the first clamp arm 11.

[0037] Preferably, the latch 4 is closer to the jaws 13 when unlocking than when locking, so that when the user needs to lock, they can grasp the other end of the two jaws 13 to engage them, and then press down with their thumb (i.e., push it away from the jaws 13) to lock the latch 4, making the operation easier and more convenient. Specifically, when the two jaws 13 are engaged, the direction in which the latch 4 slides relative to the first locking part 2 is located on the extension line of the line connecting the rotation axis of the jaws 13 and the jaws 13, which facilitates user operation and ensures the locking effect, but is not limited to this. In other embodiments, the direction in which the latch slides relative to the first locking part may also be inclined to the extension line of the line connecting the rotation axis of the jaws 13 and the jaws 13.

[0038] In this embodiment, the second locking part 3 is provided with a first slide 31. One end of the first slide 31 is a closed end 311, and the other end is an open end 312. The first slide 31 is the latching part. When the two jaws 13 are engaged, locking is achieved by sliding the other end of the latch 4 from the open end 312 of the first slide 31 into the first slide 31, ensuring the locking effect and making it difficult for the other end of the latch 4 to disengage. Preferably, when the two jaws 13 are engaged, the first slide 31 is located on the extension line of the line connecting the jaws 13 and the rotation axis of the pliers arm 1, which facilitates user operation. Specifically, when the nail clippers are locked, the other end of the latch 4 is engaged in the first slide 31 and close to the closed end 311 of the first slide 31, which further ensures the locking effect. The other end of the latch 4 abuts against the inner sidewall of the first slide 31 near the first pliers arm 11.

[0039] In other embodiments, the latching part may be a protrusion provided on the second locking part and near one end of the first clamp arm 11. The latch can be slid relative to the first locking part to lock the other end of the latch into the protrusion, or to unlock the latch by disengaging the other end of the latch from the protrusion.

[0040] In this embodiment, the second locking part 3 is further provided with a second slide 32 extending along the swing direction of the first clamp arm 11 relative to the second clamp arm 12. One end of the second slide 32 is connected to the opening end 312 of the first slide 31, and the other end extends toward the first clamp arm 11. When locking is required, when the two jaws 13 are in an engaged state, the latch 4 is pushed to slide relative to the first locking part 2, so that its other end enters the first slide 31 from the opening end 312 of the first slide 31 and slides to the closed end 311 of the first slide 31 to achieve locking. Figure 4 As shown. When unlocking is required, the latch 4 is pushed to slide relative to the first locking part 2, causing its other end to slide to the opening end 312 of the first slide rail 31. It then disengages from the first slide rail 31 from the opening end 312 and enters the second slide rail 32 to achieve unlocking. Figure 7 As shown, when the nail clippers are unlocked, the other end of the latch 4 can slide in the second slide rail 32, allowing the two jaws 13 to switch between a separated state and an engaged state. Specifically, Figure 4 , Figure 7 The first slide rail 31 and the second slide rail 32 are separated by a dotted line. In other embodiments, the second slide rail may not be provided, and when the two jaws switch between the separated state and the engaged state, the other end of the latch moves directly outside the first slide rail.

[0041] Preferably, the other end of the second slide rail 32 is provided with a notch 321, which can increase the swing distance of the first clamp arm 11 relative to the second clamp arm 12 without increasing the width of the second locking part.

[0042] The first locking part 2 is provided with an elongated hole 21. One end of the latch 4 is slidably connected to the elongated hole 21. When the two jaws 13 are engaged, the extension direction of the elongated hole 21 is consistent with the extension direction of the first slide rail 31, thereby ensuring that the latch 4 slides smoothly.

[0043] like Figure 9 As shown, one end of the latch 4 is provided with an operating protrusion 41, and the other end is provided with a locking protrusion 42. The diameter of the locking protrusion 42 and the operating protrusion 41 is larger than the width of the elongated hole 21. The latch 4 passes through the elongated hole 21. The operating protrusion 41 is located on the side of the first locking part 2 away from the second locking part 3, so as to facilitate the user to push and operate. The locking protrusion 42 is located on the side of the first locking part 2 facing the second locking part 3, so as to slide and cooperate with the first slide rail 31 and the second slide rail 32.

[0044] In this embodiment, the first slide rail 31 and the second slide rail 32 are grooves, and the grooves are disposed on the side of the second locking part 3 facing the first locking part 2. In other embodiments, the first slide rail and the second slide rail can be sliding holes.

[0045] The latch 4 is fitted with a silicone ring 5, which fits between the first locking part 2 and one end of the latch 4. Specifically, as shown in the figure... Figure 9 As shown, the first locking part 2 is located on the side opposite to the second locking part 3 and has a groove 211 around the elongated hole 21. The silicone ring 5 is fitted into the operating protrusion 41 and the groove 211 of the latch 4.

[0046] Preferably, the first locking part 2 and the second locking part 3 are sheet-like to reduce material usage, decrease the weight of the nail clippers, and lower costs. Specifically, the opposing sides of the first locking part 2 and the second locking part 3 fit together, making the nail clippers more aesthetically pleasing.

[0047] This utility model discloses a nail clipper with a locking structure. The locking structure is provided on opposite sides of the two clipper arms, and includes a latch 4, a first locking part 2, and a second locking part 3. The first locking part 2 and the second locking part 3 are arranged opposite each other along the rotation axis of the clipper arms, avoiding the problems of existing locking structures affecting operation and being easily accidentally activated. The latch 4 extends along the rotation axis of the clipper arms, and one end is slidably connected to the first locking part 2. The second locking part 3 has a latching part. When the two jaws 13 are in the engaged state, the latch 4 slides relative to the first locking part 2, causing its other end to engage or disengage with the latching part, thus locking or unlocking. The structure is simple, with few parts, and low cost. Users only need to hold the other end of the two clipper arms and push the latch 4 to easily lock or unlock the nail clipper, making operation simple and convenient.
