Description

Technical Field

[0001] This utility model relates to the field of personal care tools, and in particular to a pair of scissors with an electric nail-grinding head. Background Technology

[0002] In daily nail care, trimming and filing are two key steps. Currently, nail clippers and electric nail files are sold as separate products. When doing nail care, people often need to first use nail clippers to trim the nails to their initial shape, and then find and use an electric nail file to smooth the edges. This process is not only cumbersome, requiring frequent tool changes and significantly reducing efficiency, but also prone to being misplaced, leading to inconvenience. In conclusion, the current separation of nail clippers and electric nail files fails to meet the demand for efficient and convenient nail care, necessitating a multi-functional nail care tool that integrates both functions. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a pair of scissors with an electric nail grinding head, which combines the functions of scissors and electric nail grinding.

[0004] The technical solution of this utility model is as follows: A pair of scissors with an electric nail grinding head includes a main handle, a pinch handle, and a pair of cutting heads. The pair of cutting heads are hinged in the middle, and the tail handles of the pair of cutting heads are respectively connected to one end of the main handle and one end of the pinch handle. The heads of the pair of cutting heads form matching cutting blades. When the pinch handle rotates relative to the main handle, it drives the cutting blades of the pair of cutting heads to open and close. The main handle is provided with an electric nail grinding unit, which includes a circuit board, a power component electrically connected to the circuit board, a start switch, and a nail grinding head driven to rotate by the power component. The nail grinding head is located at the other end of the main handle, the circuit board and the power component are built into the main handle, and the start switch is located on the surface of the main handle.

[0005] By adopting the above technical solution, the trimming function of scissors and the electric nail file function are integrated into one, realizing the multi-functional integration of nail care tools. After trimming their nails, users can directly use the electric nail file head on the same tool to file their nails without having to change tools midway, simplifying the nail care operation steps and improving care efficiency. At the same time, the integrated design reduces the number of tools, making it easier to store and carry, reducing the problem of tools being easily lost when stored separately, and providing users with a more convenient and efficient nail care solution.

[0006] A further feature of this invention is that the electric nail grinding unit includes a protective cover that covers the outside of the nail grinding head. The protective cover has a nail insertion port, which is used to expose part of the internal structure of the nail grinding head.

[0007] With the aforementioned further design, this system, by adding a protective shield, not only protects the nail file head from external damage and extends its lifespan, but also provides users with a safer and more stable nail filing environment. The nail insert design makes nail filing more precise; users simply insert their nail into the insert to easily contact the nail file head for filing, without worrying about accidentally injuring their fingers or other parts of their body.

[0008] A further feature of this invention is that the nail insertion port is located on the end face of the anti-wear cover and has a crescent-shaped insertion structure.

[0009] With the further refinement described above, the crescent-shaped insert structure conforms more closely to the natural curve of the nail, further improving the precision and comfort of nail filing. Users can insert the nail more naturally, reducing operational difficulty, while the crescent shape effectively limits the range of motion of the filing head, further reducing the risk of accidental injury.

[0010] A further feature of this invention is that the nail insertion port extends from the outer periphery of the anti-wear cover to the end face of the anti-wear cover, forming a channel structure.

[0011] With the above-described further design, the nail insertion port extends from the outer periphery of the anti-abrasion shield to the end face, forming an open channel structure. This design not only makes nail insertion smoother but also increases the flexibility of the nail filing operation.

[0012] A further feature of this invention is that the anti-wear cover and the main handle are connected by a rotating snap-fit ​​structure. The rotating snap-fit ​​structure includes a snap block and a snap-fit ​​groove respectively provided on the anti-wear cover and the main handle. The snap-fit ​​groove has an inlet and outlet arranged along the axial direction and a snap-fit ​​opening arranged along the circumferential direction. The inlet and outlet are connected to the snap-fit ​​opening. The snap block can enter the inlet and outlet along the axial direction and slide into the snap-fit ​​opening through the circumferential rotation of the anti-wear cover to form an axial fixation.

[0013] With the above-mentioned further design, the rotating snap-fit ​​structure enables quick disassembly and assembly of the anti-wear cover, facilitating the cleaning or replacement of the grinding head; at the same time, the axial fixation is reliable, preventing the anti-wear cover from accidentally falling off during use and ensuring structural stability.

[0014] A further feature of this invention is that the scissors also include a first cap, which is pluggably connected to the main handle and is used to cover the nail-grinding head.

[0015] With the aforementioned further design, the first cap is intended to protect the nail-grinding head from external contamination or damage, while also providing a convenient storage method when not in use. Through a pluggable connection, users can easily install or remove the first cap from the main handle, making the operation simple and quick.

[0016] A further feature of this invention is that the knife also includes an elastic element and a locking device. The elastic element is located between the main handle and the pinch handle, and can drive the pinch handle to rotate and open, thereby keeping the blades of the pair of scissors open. The locking device can lock the pinch handle that is folded to one side of the main handle.

[0017] With the above-mentioned further design, the elastic element allows the handle to automatically spring open when the scissors are not in use, keeping the blades open and making it easy for users to quickly insert their nails for trimming, reducing the force required for hand operation. At the same time, the locking device locks the handle to one side of the main handle, keeping the scissors closed, making them easy to carry or store, and effectively preventing the blades from accidentally opening and causing injury.

[0018] A further feature of this invention is that the locking device includes a pusher and a locking plate. The locking plate is located on the main handle or the pinch handle. The pusher can push the locking plate to lock the scissor head opposite to the handle body where the locking plate is located or connected to the other handle body.

[0019] With the above-mentioned further design, the push-button design allows users to control the locking and unlocking of the locking plate with a simple pushing action. When it is necessary to lock the handle, the user only needs to gently push the push-button, and the locking plate will lock into the preset position, firmly locking the handle to one side of the main handle, ensuring that the scissors will not open accidentally during carrying or storage; similarly, when it is necessary to unlock the handle for use, the user only needs to push the push-button in the opposite direction, and the locking plate will disengage from the locked position, allowing the handle to rotate freely, thereby opening the scissors blade.

[0020] A further feature of this invention is that the locking plate is slidably disposed within the handle, the push-twist mechanism is disposed on the surface of the handle and is linked with the locking plate, and the scissor head connected to the main handle is provided with a locking slot for the locking plate to slide in and out.

[0021] With the aforementioned further design, the locking plate is integrated into the handle. A push or twist action causes the locking plate to slide into or out of the corresponding latch on the scissor head, resulting in a compact locking structure. Furthermore, the shape and size of the latch match the locking plate, further enhancing the stability and reliability of the lock.

[0022] A further feature of this invention is that it includes a second cap, which is hinged to the main handle and used to cover the blades of a pair of scissors.

[0023] With the above-mentioned further design, the second cap effectively protects the scissor blades when not in use, preventing accidental cuts, while also keeping the scissors clean and safe. Furthermore, the hinged design between the second cap and the main handle allows users to easily open or close the cap, making operation simple and quick. Attached Figure Description

[0038] The working principle of this utility model:

[0039] 1. Trimming nails: Position the pair of clippers in the corresponding positions. Hold the main handle and the pinch handle, and push or twist backward with your fingers. This will cause the locking plate inside the pinch handle to disengage from the corresponding clipper's lock, thus releasing the pinch handle from its lock. At this point, the elastic element will cause the pinch handle to automatically spring open, keeping the blades of the pair of clippers open. Then, place the nail to be trimmed between the blades and squeeze the pinch handle firmly to close the blades and complete the trimming.

[0040] When not using the scissors, squeeze the handle firmly to bring it together on one side of the main handle, and push the push knob forward to move the locking plate into the locking slot of the scissor head connected to the main handle, thereby locking the handle to one side of the main handle and keeping the scissors in a closed state.

[0041] At this point, rotate the second cap to cover and protect the scissor blades, preventing accidental cuts.

[0042] 2. Nail Buffing: After trimming the nails, align the nail file head with the desired position and activate the start switch. The power unit will then rotate the nail file head at high speed. Next, insert the nail to be filed into the nail slot and use the nail file head to file the nail surface until a satisfactory smoothness is achieved. The nail file head is replaceable; for coarse filing, select the coarse file head; for fine filing or polishing, select the corresponding fine file head or polishing head.

[0043] After polishing is complete, press the start switch again to turn off the electric polishing unit.

[0044] When the electric nail grinding function is not needed, the first cap can be attached to the main handle to cover and protect the nail grinding head. In addition, when it is necessary to clean or replace the nail grinding head, the anti-abrasion cover can be removed by first rotating and then pulling it out. First, rotate the locking block on the anti-abrasion cover circumferentially to slide it out of the locking slot, and then slide it out axially from the inlet and outlet, thereby achieving quick installation and removal of the anti-abrasion cover.
