[0002] A nail grinder is a tool that roughens the surface of nails. When doing manicures, it can facilitate the firm attachment of nail polish, nail tips, etc. to the nails.

[0003] In addition to manual files, nail grinding equipment also includes electric grinding devices driven by electricity. Most of them have a pen-shaped housing. Inside the housing, there is an electric motor. The motor drives the grinding tool to rotate at a high speed. The high-speed rotating grinding tool contacts the outer surface of the nail to achieve the grinding effect.

[0004] However, when using the above-mentioned prior art, generally two hands are required for operation. One hand holds the grinding tool, and the other hand fixes the customer's finger to avoid the shaking of the suspended finger caused by the torque generated when the grinding tool rotates at a high speed. If the finger is directly placed on the table, the distance between the nail and the table will be reduced, which will cause inconvenience in using the tool when grinding the nail. For the above reasons, it is very troublesome to grind one's own nails by oneself.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figure 1-7 , a nail grinder, comprising a base mechanism 1, a grinding mechanism 2 and a hinge shaft 3. One end of the base mechanism 1 is hinged to one end of the grinding mechanism 2 through the hinge shaft 3. The grinding mechanism 2 rotates about the hinge shaft 3. A torsion spring 4 is sleeved on the hinge shaft 3. Two ends of the torsion spring 4 are respectively connected to the base mechanism 1 and the grinding mechanism 2. The torsion spring 4 is used to apply an elastic traction force to the base mechanism 1 and the grinding mechanism 2.

[0031] The base mechanism 1 includes a support base 101. One end of the top of the support base 101 is fixedly connected with a hinge bracket 102. The hinge shaft 3 is installed between the inner walls of the hinge bracket 102. The other end of the top of the support base 101 is provided with a finger placement groove 103. The finger placement groove 103 extends to the middle of the support base 101. The finger placement groove 103 is used to place fingers.

[0032] The grinding mechanism 2 includes an upper clamping plate 201. One end of the upper clamping plate 201 is hinged to the hinge shaft 3. A grinding piece installation groove 204 is opened at the bottom of the other end of the upper clamping plate 201. The length of the grinding piece installation groove 204 is shorter than the length of the finger placement groove 103.

[0033] A power switch 203 is installed on the top of the upper clamping plate 201. A driving motor 205 is fixedly connected to the right end of the inner wall of the grinding piece installation groove 204. The driving motor 205 rotates after being powered. The power switch 203 is used to control the energization of the driving motor 205. A grinding piece 206 is inserted into the output end of the driving motor 205. The driving motor 205 is used to drive the grinding piece 206 to rotate. The outer surface of the grinding piece 206 protrudes from the bottom of the upper clamping plate 201. The outer surface of the grinding piece 206 is made of a soft material, which can avoid accidentally hurting fingers while grinding nails.

[0034] Through the above technical solution, a finger placement groove 103 is opened on the top of the support base 101 for placing fingers, and an upper clamping plate 201 is hinged on the right side of the support base 101, and a grinding piece installation groove 204 is opened at the bottom of the upper clamping plate 201, and a driving motor 205 is installed inside the grinding piece installation groove 204 to drive the grinding piece 206 to rotate. When the upper clamping plate 201 is pressed down, the grinding piece 206 will gradually approach and grind between the upper clamping plate 201, and the finger will rotate inside the finger placement groove 103 as needed. Because the finger placement groove 103 is supported, the finger will not shake, achieving the effect of facilitating single-person operation.

[0035] When polishing the nail, apply pressure to the upper clamping plate 201 as needed. Normally, the nail is arched, and the outer surface of the polishing piece 206 is also arched, so the polishing area will not be very large. When the edge of the nail needs to be polished, slightly apply pressure to deform the polishing piece 206 to increase the coverage area of ​​the nail;

[0036] In a normal manicure process, the nail piece is adhered to the main surface of the nail by an adhesive, and the side seams on both sides are filled with adhesive. Therefore, the side seams on both sides of the nail do not need to be polished, so the polishing piece 206 does not need to be set very small to polish the side seams of the nail.

[0037] Specifically, a recovery groove 104 is provided at the end of the support base 101 close to the finger placement groove 103, a recovery drawer 106 is inserted into the recovery groove 104, a through groove 105 is provided at the inner bottom of the finger placement groove 103, and the recovery groove 104 and the through groove 105 are connected.

[0038] Through the above technical solution, when polishing the nails, a small amount of powder will be produced due to the polishing of the polishing piece 206. The powder will enter the recovery tank 104 through the through groove 105 and be collected by the recovery drawer 106 to facilitate subsequent cleaning.

[0039] Specifically, the outer surface of the recovery drawer 106 is in contact with the inner wall of the recovery tank 104 , and magnets are installed on the right end of the recovery drawer 106 and the right inner wall of the recovery tank 104 , and the magnetic poles of the two magnets attract each other.

[0040] Through the above technical solution, two magnets are attracted to each other to make the recovery drawer 106 adsorbed inside the recovery slot 104, so that when the device is moved and carried, the recovery drawer 106 will not be easily separated from the inside of the recovery slot 104.

[0041] Specifically, a storage battery is installed inside the upper clamping plate 201. A charging port 202 is provided on the side of the upper clamping plate 201. The charging port 202 charges the storage battery through an external power supply, and the power switch 203 controls the power supply of the storage battery to the drive motor 205.

[0042] Through the above technical solution, the storage battery is used to supply power to the drive motor 205. Without the constraint of cables, it can be conveniently used and carried anywhere. When the storage battery runs out of power, it can be charged by connecting the charging port 202 to a power source.

[0043] Specifically, the grinding member 206 includes a transmission rod 2061, and a support retaining piece 2062 is fixedly connected to the outer surface of the transmission rod 2061;

[0044] The outer surface of the transmission rod 2061 is penetrated and connected with a grinding roller 2063. One end of the grinding roller 2063 is lapped with the support retaining piece 2062, and a nut is threadedly connected to the end of the transmission rod 2061 to fix the other end of the grinding roller 2063.

[0045] Through the above technical solution, since the grinding roller 2063 is a consumable part, the grinding roller 2063 and the transmission rod 2061 are installed in a separable manner, so that the grinding roller 2063 can be conveniently replaced individually or the type of the grinding roller 2063 can be changed according to needs;

[0046] The provided support retaining piece 2062 is used to limit the installation depth of the grinding roller 2063 and cooperate with the nut to fix the grinding roller 2063;

[0047] In order to facilitate the fixing of the grinding roller 2063, the inside of the grinding roller 2063 is a rigid sleeve for cooperating with the support retaining piece 2062 and the nut to achieve fixation. The outer surface of the grinding roller 2063 is a soft rough layer for achieving the grinding effect and protecting fingers.

[0048] Specifically, a locking groove is provided at the insertion joint of the transmission rod 2061 and the drive motor 205. The locking groove cooperates with the spring beads in the plug at the end of the drive motor 205 to lock the position of the transmission rod 2061. The end of the insertion joint of the transmission rod 2061 and the drive motor 205 is a polygonal cylinder.

[0049] Through the above technical solution, the style of the insertion joint of the transmission rod 2061 and the drive motor 205 is set, so that the transmission rod 2061 can be conveniently installed. When the transmission rod 2061 is inserted into the end of the drive motor 205, the locking groove will cooperate with the spring beads, so that the transmission rod 2061 will not easily come off, and the rhombic end cooperates with the cross-section inside the end of the drive motor 205 to realize the transmission of the transmission rod 2061;

[0050] Its structural relationship is the same as the connection relationship between the drill bit and the end of the impact drill, and it is also for achieving quick disassembly and assembly.

[0051] Specifically, a rotatable support frame 107 is hinged to the outer surface on the left side of the support base 101, and a positioning card slot 207 is opened at the top of the upper clamping plate 201; when the support frame 107 is flipped, the support frame 107 is stuck inside the positioning card slot 207 to limit the angle of the upper clamping plate 201.

[0052] Through the above technical solution, the support frame 107 has two functions:

[0053] First, tilt the support frame 107 from the bottom of the support base 101 to the right side to the maximum angle, so that the support frame 107 can be used as a support, causing the left side of the support base 101 to tilt up, facilitating the placement of fingers inside the finger placement groove 103, which is more comfortable than placing fingers horizontally.

[0054] Second, press down the upper clamping plate 201 to make the left sides of the support base 101 and the upper clamping plate 201 approach each other, and then flip the support frame 107 upward and stick it inside the positioning card slot 207 above the upper clamping plate 201, so that the support base 101 and the upper clamping plate 201 are folded together to facilitate the storage and carrying of the machine.

[0055] During use, a finger placement groove 103 is opened at the top of the support base 101 for placing fingers, the upper clamping plate 201 is hinged to the right side of the support base 101, a grinding part installation groove 204 is opened at the bottom of the upper clamping plate 201, and a driving motor 205 is installed inside the grinding part installation groove 204 to drive the grinding part 206 to rotate. When the upper clamping plate 201 is pressed down, the grinding part 206 will gradually approach and grind between them, and the fingers will rotate inside the finger placement groove 103 as needed. Because of the support of the finger placement groove 103, the fingers will not shake, achieving the effect of facilitating single-person operation.

[0056] By installing a rotatable support frame 107 on the support base 101 and opening a corresponding positioning card slot 207 at the top of the upper clamping plate 201, when not in use, press the upper clamping plate 201 to make the angle between the upper clamping plate 201 and the support base 101 smaller, and then rotate the support frame 107 to make the support frame 107 stuck inside the positioning card slot 207, and be pulled by the elasticity of the torsion spring 4, so that the whole device can be folded, achieving the effect of convenient storage and portability.

[0057] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
