Description

Technical Field

[0001] This utility model belongs to the field of nail care tool technology, specifically relating to a nail clipper. Background Technology

[0002] Nail clippers are everyday tools specifically designed for trimming nails. A typical nail clipper consists of two clamping heads that can clamp and separate, two handles connected to the clamping heads, and a spring mechanism that automatically separates the clamping heads. Each clamping head has blades on opposite sides. Rotating the handles causes the blades to rotate and clamp and separate. To use, insert the nail between the blades, then press the handles to clamp the blades together, allowing the nail to be cut. Releasing the handles causes the spring mechanism to automatically push the clamping heads apart, making it easy to clamp and separate the nails again. Nail trimming is very convenient.

[0003] However, existing nail clipper designs also have the following shortcomings: the two clippers cannot be locked when clamped, so when the nail clippers are not in use, the two clippers remain in a detached state due to the elastic element. This makes the nail clippers bulky and inconvenient to carry and store. Furthermore, the detached state also increases the risk of cuts from the clipper blades, making them unsafe to use. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a nail clipper that can lock the two pliers heads in a clamped state.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a nail clipper, comprising a first clipper head and a second clipper head that can clamp and separate from each other, a first clipper handle connected to the first clipper head, and a second clipper handle connected to the second clipper head. The first clipper head and the second clipper head are provided with cutting edges on opposite sides. Rotating the two clipper handles will cause the cutting edges of the two clipper heads to clamp and separate from each other. The nail clipper also includes a locking mechanism for locking the two clipper heads in a clamped state. The locking mechanism includes a slider slidably disposed on the first clipper handle, a buckle connected to the slider, and a latch on the second clipper handle. When the two clipper heads are in a clamped state, the slider can drive the buckle to engage and disengage from the latch.

[0006] In the above solution, a slider and a latch are slidably mounted on the first pliers handle, and a locking position is provided on the second pliers handle. When the two pliers heads are clamped, the slider can be pushed to engage the latch and the locking position, preventing the two pliers handles from rotating in the opening direction. This locks the two pliers heads in the clamped state, preventing the nail clippers from automatically opening when not in use. This results in the nail clippers occupying less space, making them convenient to carry and store, and eliminating the risk of cuts from the pliers blades, ensuring safe use. When it is necessary to release the lock on the two pliers heads, the slider can be pushed to disengage the latch and the locking position, thus releasing the lock. At this time, the two pliers handles can rotate in the opening direction, thereby causing the two pliers heads to rotate and separate.

[0007] Furthermore, the aforementioned latch is a latch block located at the front end of the slider, and the latching position is a protrusion located on the second clamp handle. When the two clamp heads are in the clamped state, sliding the slider forward causes the latch block to abut against the rear side of the protrusion, thus realizing the latch and latching position engagement structure. At this time, the protrusion will block the latch block to prevent the first clamp handle from rotating in the opening direction, thereby locking the two clamp heads in the clamped state. Sliding the slider backward causes the latch block to disengage from the rear side of the protrusion, thus realizing the latch and latching position disengagement structure, thereby releasing the lock. At this time, without the obstruction of the protrusion, the first clamp handle can rotate in the opening direction and cause the two clamp heads to separate.

[0008] Furthermore, a sliding groove is provided on the right side of the front end of the first clamp handle, and a sliding hole is provided at the bottom of the groove, which penetrates the left and right side walls of the first clamp handle. The slider is placed in the sliding groove and can slide back and forth along the sliding groove. A screw passes through the sliding hole and is connected to the slider, which facilitates the installation of the slider. The outer end of the screw is provided with a nail head. The diameter of the nail head and the width of the slider are both greater than the width of the sliding hole, so that the nail head and the slider cannot pass through the sliding hole, thereby ensuring the installation stability of the screw and the slider on the first clamp handle.

[0009] Furthermore, a first spring is fitted on the outside of the aforementioned screw. The right end of the first spring abuts against the first clamp handle, and the left end of the first spring abuts against the nail head. The first spring is in a compressed state. The first spring acts on the nail head through its own elastic force to press the left side of the slider against the bottom of the groove, thereby increasing the friction between the slider and the bottom of the groove and preventing the slider from sliding naturally. This can avoid the slider from accidentally locking or unlocking due to natural sliding. When locking or unlocking is required, the slider needs to be manually pushed to slide to lock or unlock.

[0010] Furthermore, a clearance groove is provided on the left side of the first pliers handle corresponding to the nail head position. The nail head and the first spring are placed in the clearance groove, and the right end of the first spring abuts against the bottom of the clearance groove. The nail head and the first spring can slide back and forth with the slider in the clearance groove, so that the nail head will not protrude from the outside of the first pliers handle, making the nail clipper structure more compact.

[0011] Furthermore, the outer side of the slider is provided with anti-slip texture, which can increase the friction on the outer side of the slider and prevent the hand from slipping when pushing the slider.

[0012] Furthermore, the aforementioned nail clippers also include an elastic element for pushing the two clipper heads apart, so that the two clipper heads remain in a separated state without being locked, realizing the automatic separation function of the two clipper heads, facilitating the re-clamping operation of the two clipper heads, and making the trimming operation more convenient.

[0013] Furthermore, the aforementioned elastic element is a second spring. Spring grooves are respectively provided on the lower side of the front end of the first clamp handle and the upper side of the front end of the second clamp handle. The upper and lower ends of the second spring are respectively placed in the spring grooves on the corresponding sides. The installation of the second spring does not require disassembling the clamp handles, making installation convenient. Without the action of external force, the second spring will automatically push the two clamp handles to rotate in the opening direction through its own elastic force.

[0014] Furthermore, the first pliers handle has a first turntable at its front end, and the second pliers handle has a second turntable at its front end. The first pliers head is connected to the first turntable, and the second pliers head is connected to the second turntable. A protrusion is located at the edge of the second turntable. The two turntables are stacked on top of each other, and a pin passes through the first turntable and connects to the second turntable, allowing the first turntable to rotate around the pin, thereby causing the first pliers head to rotate relative to the second pliers head for clamping and disengaging. The two pliers handles are rotatably connected through the stacked turntables. Since the two turntables are always in surface contact during relative rotation, this makes the rotation of the two pliers handles more stable, improving the stability of the nail clippers. The outer end of the pin is provided with a cap, which prevents the first turntable from shifting to the left, ensuring the assembly stability of the two turntables. A receiving groove is provided on the outer side of the first turntable corresponding to the position of the cap, and the cap is placed in the receiving groove, so that the cap does not protrude from the outside of the first turntable, further improving the structural compactness of the nail clippers.

[0015] Furthermore, both the first and second pliers are equipped with baffles on their left and right sides. This reduces the gap between the left and right sides of the first and second pliers when the nail clippers are clamped, so that when trimming nails, the cut nail clippings are blocked by the baffles on both sides and remain between the two pliers, preventing nail clippings from splashing onto the ground through the gap between the left and right sides of the first and second pliers, making nail trimming more convenient and hygienic.

[0016] This utility model of nail clippers can be locked in a clamped state, making it convenient to carry and store, and preventing cuts from the clipper blades, ensuring safe use. Locking and unlocking are simple and convenient. When the nail clippers are in the clamped state, pushing the slider forward causes the locking block to abut against the rear of the protrusion, thus locking the clippers in the clamped state. Pushing the slider backward disengages the locking block from the rear of the protrusion, thus unlocking the clippers. Furthermore, the first spring prevents the slider from sliding naturally, avoiding accidental locking or mis-locking due to natural slippage, and the stop block prevents nail clippings from flying onto the ground, making nail trimming more hygienic.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0026] Example 1

[0027] like Figure 1 As shown, this embodiment provides a nail clipper, including a first clipper head 1 and a second clipper head 2 that can clamp and separate from each other, a first clipper handle 11 connected to the first clipper head 1, and a second clipper handle 21 connected to the second clipper head 2. The front ends of the first clipper head 1 and the second clipper head 2 are provided with clipper blades 10. Rotating the two clipper handles will cause the clipper blades 10 of the two clipper heads to clamp and separate from each other.

[0028] The first pliers handle 11 has a first turntable 114 at its front end, and the second pliers handle 21 has a second turntable 212 at its front end. The first pliers head 1 is connected to the front end of the first turntable 114, and the second pliers head 2 is connected to the front end of the second turntable 212. The two turntables are stacked horizontally, while the two pliers heads are positioned vertically opposite each other. A pin 6 passes through the first turntable 114 and connects to the second turntable 212, allowing the first turntable 114 to rotate around the pin 6, thus causing the first pliers head 1 to rotate relative to the second pliers head 2 for clamping and disengagement. The two pliers handles are rotatably connected through the stacked turntables. Since the two turntables are always in surface contact during relative rotation, this makes the rotation of the two pliers handles more stable, improving the stability of the nail clippers. The outer end of the pin 6 has a cap 61, which prevents the first turntable 114 from shifting to the left, ensuring the assembly stability of the two turntables. Figure 2 As shown, a receiving groove 1141 is provided on the outer side of the first turntable 114 corresponding to the position of the shaft cap 61. The shaft cap 61 is placed in the receiving groove 1141, so that the shaft cap 61 will not protrude from the outside of the first turntable 114, making the nail clipper structure more compact.

[0029] The aforementioned nail clippers also include a locking mechanism for locking the two clipper heads in a clamped state. The locking mechanism in this embodiment includes a slider 4 slidably disposed on the right side of the front end of the first clipper handle 11, a buckle connected to the slider 4, and a buckle on the second turntable 212 disposed on the second clipper handle 21. When the two clipper heads are in a clamped state, the slider 4 can drive the buckle to engage and disengage from the buckle.

[0030] Specifically, the aforementioned latch is a latching block 41 located at the front end of the slider 4, and the latching position is a protrusion 211 located on the upper side edge of the second turntable 212, such as... Figure 3 , 4 As shown, when the two pliers heads are in the clamped state, sliding the slider 4 forward causes the upper side of the locking block 41 to abut against the rear side of the protrusion 211, thus realizing the above-mentioned buckle and latching function. At this time, the protrusion 211 will block the locking block 41 to prevent the first pliers handle 11 from rotating in the opening direction, thereby locking the two pliers heads in the clamped state, preventing the nail clippers from opening automatically when not in use, making the nail clippers occupy less space, convenient to carry and store, and preventing cuts from the pliers blades, ensuring safe use.

[0031] When it is necessary to unlock the two clamp heads, such as Figure 4 , 5 As shown, the sliding block 4 can be slid backward to disengage the locking block 41 from the rear side of the protrusion 211, thus realizing the above-mentioned function of disengaging the buckle from the latch and releasing the lock. At this time, without the obstruction of the protrusion 211, the first clamp handle 11 can rotate in the opening direction, thereby causing the first clamp head 1 to rotate and separate relative to the second clamp head 2.

[0032] Example 2

[0033] This embodiment is a further improvement on the structure of the nail clipper in Embodiment 1. The improvement is as follows: Figure 1 , 2 As shown, a groove 111 is provided on the right side of the front end of the first clamp handle 11. A sliding hole 112 is provided at the bottom of the groove 111, penetrating the left and right side walls of the first clamp handle 11. The slider 4 is fitted into the groove 111 and can slide back and forth along the groove 111. A screw 3 passes through the sliding hole 112 and connects to the slider 4 to facilitate the installation of the slider 4. While the slider 4 slides, the screw 3 also slides along the sliding hole 112. The outer end of the screw 3 is provided with a nail head 31. The diameter of the nail head 31 and the width of the slider 4 are both larger than the width of the sliding hole 112, so that the slider 4 and the nail head 31 cannot pass through the sliding hole 112, thus ensuring the installation stability of the screw 3 and the slider 4 on the first clamp handle 11.

[0034] The screw 3 is fitted with a first spring 32 on its outer side. The right end of the first spring 32 abuts against the first clamp handle 11, and the left end of the first spring 32 abuts against the nail head 31. The first spring 32 is in a compressed state. The first spring 32 acts on the nail head through its own elastic force. The screw 3 pulls the slider 4, causing the left side of the slider 4 to be pressed against the bottom of the groove 111, thereby increasing the friction between the slider 4 and the bottom of the groove 111. This prevents the slider 4 from sliding naturally, thus avoiding accidental locking or unlocking due to natural sliding. When locking or unlocking is required, the slider 4 needs to be manually pushed to slide to lock or unlock.

[0035] As an improvement to this embodiment, a clearance groove 113 is provided on the left side of the first pliers handle 11 corresponding to the nail head 31. The nail head 31 and the first spring 32 are placed in the clearance groove 113, and the right end of the first spring 32 abuts against the bottom of the clearance groove 113. The nail head 31 and the first spring 32 can slide back and forth with the slider 4 in the clearance groove 113, so that the nail head 31 will not protrude from the outside of the first turntable 114, further improving the structural compactness of the nail clippers. In addition, the outer side of the slider 4 is provided with anti-slip texture 42, which can increase the friction on the outer side of the slider 4 and prevent the hand from slipping when pushing the slider 4 to slide.

[0036] Example 3

[0037] This embodiment is a further improvement on the nail clipper structure of Embodiment Two. The improvement lies in, for example... Figure 1 As shown, the nail clippers also include an elastic element 5 for pushing the two clipper heads apart, so that the two clipper heads remain in the separated state without being locked, realizing the automatic separation function of the two clipper heads, facilitating the re-clamping operation of the two clipper heads, and making the trimming operation more convenient.

[0038] Specifically, the elastic element 5 mentioned above is a second spring. Spring grooves 50 are respectively opened on the lower front side of the first clamp handle 11 and the upper front side of the second clamp handle 21. The upper and lower ends of the second spring are respectively placed in the spring grooves 50 on the corresponding sides, so that the installation of the second spring does not require disassembling the clamp handles, making the installation convenient. Without the action of external force, the second spring 50 will automatically push the two clamp handles to rotate in the opening direction through its own elastic force, thereby realizing the automatic separation function of the two clamp heads.

[0039] As an improvement to this embodiment, such as Figure 3 , 4As shown, the first pliers head 1 and the second pliers head 2 are provided with baffles 7 on both the left and right sides. This reduces the gap between the left and right sides of the first pliers head 1 and the second pliers head 2 when the nail clippers are clamped. This allows the cut nail clippings to be blocked by the baffles 7 on both sides and remain between the two pliers heads, preventing nail clippings from splashing onto the ground through the gap between the left and right sides of the first pliers head 1 and the second pliers head 2. This makes nail trimming more convenient and hygienic.

[0040] When using the nail clippers of this utility model, such as Figure 5 , 6 As shown, sliding the slider 4 backward causes the locking block 41 to disengage from the protrusion 211, thus unlocking the lock and automatically separating the two pliers heads. Then, insert the nail between the two pliers heads, squeeze the handles to clamp the two blades 10, and cut the nail. Releasing the handles causes the first spring to automatically push the two pliers heads apart, making nail trimming very convenient. When not in use, as... Figure 3 , 4 As shown, you can grip the two pliers handles to clamp the two pliers heads together, and then push the slider 4 forward to move the upper side of the locking block 41 against the rear side of the protrusion 211, thus locking the two pliers heads in the clamped state, which is convenient for carrying and storing.

[0041] 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.
