[0056] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the drawings, but the present utility model is not limited to these embodiments

[0057] As Figures 1-6 shown, an electric nail grinder includes

[0058] A housing 1, an installation cavity is formed therein, and a first through hole 11 is formed on one side surface of the housing 1, and the first through hole 11 communicates with the installation cavity

[0059] A driving motor 3, which is installed in the installation cavity

[0060] A nail grinding part 15, which is placed outside the housing 1 and partially inserted into the housing 1, and is used to connect the driving motor shaft of the driving motor, so that the driving motor 3 can drive the nail grinding part 15 to work

[0061] A battery assembly 6, which is installed in the housing 1 and is electrically connected to the driving motor 3

[0062] A control assembly, which is installed in the housing 1 and the end parts thereof respectively abut against the driving motor 3 and the inner wall of the housing 1, and is used to fix the driving motor 3

[0063] Furthermore, the housing 1 is formed by splicing a front shell 17 and a rear shell 18 , and the control unit 2 is disposed on the front shell 17 . When the rear shell 18 is removed, the control unit 2 can be easily assembled on the front shell 17 .

[0064] like Figures 1-6 As shown, a mounting groove 13 is formed in the housing 1 , and the driving motor 3 is installed in the mounting groove 13 .

[0065] Among them, the control component has:

[0066] Fixed seat 5;

[0067] The circuit board 4 is clamped on the fixing seat 5, and a button 41 is provided on the circuit board 4 and is electrically connected to the driving motor and the battery pack respectively;

[0068] The fixing seat 5 is provided with a plurality of clamping parts 53, and the clamping parts 53 are distributed in the circumferential direction;

[0069] When the circuit board 4 is mounted on the fixing seat 5 , the clamping portion 53 locks the edge of the circuit board 4 , thereby achieving clamping of the circuit board 4 on the fixing seat 5 .

[0070] A connecting groove 57 is formed on the fixing seat 5, and the connecting groove 57 can be sleeved on the outer wall of the mounting groove 13, so that the connecting groove 57 cooperates with the mounting groove 13 to fix the position of the driving motor 3. At the same time, the fixing seat 5 can also be connected to the housing 1.

[0071] like Figures 1-6 As shown, a support seat 51 is also provided on the fixing seat 5 , and a support surface 510 is formed on the support seat 51 . When the circuit board 4 is against the support surface 510 , the support seat 51 can cooperate with the clamping portion 53 to fix the circuit board 4 .

[0072] Furthermore, a plurality of needle holders 42 are provided on the circuit board 4 .

[0073] The housing 1 is also provided with a light-emitting component, and the light-emitting component, the battery component 6 and the ends of the wires of the driving motor 3 are all provided with plug-in terminals.

[0074] The electrical connection between the light emitting assembly, the battery assembly 6 , the driving motor 3 and the circuit board 4 is achieved through the cooperation between the plug-in terminal and the needle seat 42 .

[0075] By adopting the connection mode of the plug-in terminal and the needle seat 42, the user can quickly insert or remove the plug-in terminal to change the connection state. This solution has high connection strength and is not easy to separate after connection. The structure is simple and convenient for users to connect accurately.

[0076] like Figures 1-6 As shown, the clamping portion 53 includes a connecting column 531 and a clamping claw 532, and the clamping claw 532 is formed at the upper end of the connecting column 531;

[0077] When the circuit board 4 is disposed on the fixing base 5, the lower surface of the circuit board 4 abuts against the first supporting seat 51, and the clamping claw 532 abuts against the upper surface of the circuit board 4;

[0078] The connecting column 531 is located on the circumferential side of the circuit board 4 to limit the displacement of the connecting column 531, thereby ensuring the relative position between the circuit board 4 and the fixing base 5 is fixed.

[0079] In this embodiment, a second supporting seat 52 is further provided on the fixing base 5;

[0080] A second supporting surface 520 and a limiting convex portion 54 are formed on the second supporting seat 52, and the limiting convex portion 54 is located at one end of the second supporting surface 520;

[0081] When the circuit board 4 abuts against the second supporting surface 520, the limiting convex portion 54 can cooperate with the connecting column 531 to limit the position of the circuit board 4. The limiting convex portion 54 can cooperate with the connecting column 531 to limit the position of the circuit board 4, thereby further preventing the circuit board 4 from shaking and maintaining the relative position between the circuit board 4 and the fixing base 5 stable.

[0082] Further, a positioning column 55 is formed on the fixing base 5, and a positioning hole 43 matching the positioning column 55 in position is formed on the circuit board 4.

[0083] The limiting convex portion 54 of the second supporting seat 52 and the clamping portion 53 can block the circuit board 4 from three directions, thereby limiting the position of the circuit board 4. The last remaining direction is to enable the opening of the pin base 42 to face outward, so as to facilitate the user to connect the terminal wire to the pin base 42.

[0084] Therefore, by providing the positioning hole 43 and the positioning column 55, during the process of disposing the circuit board 4 on the fixing base 5, it can be ensured that the position of the pin base 42 is in the designed position, that is, the limiting convex portion 54 of the second supporting seat 52 and the clamping portion 53 do not block the position of the pin base 42.

[0085] Such as Figures 1-6 shown, a deformation inclined surface 533 is formed at the upper end of the clamping claw 532.

[0086] When the circuit board 4 is placed on the fixing base 5, the circuit board 4 will first abut against the clamping claw 532.

[0087] By providing the deformation inclined surface 533 on the clamping claw 532, when the deformation inclined surface 533 is pushed, the connecting column 531 can be deformed, so that the circuit board 4 can continue to move and abut against the first supporting surface 510 and the second supporting surface 520.

[0088] When the circuit board 4 abuts against the first supporting surface 510 and the second supporting surface 520, at this time, since the deformation inclined surface 533 of the claw 532 is no longer squeezed, it will rebound, causing the claw 532 to hold one end of the circuit board 4, so as to cooperate with the first supporting surface 510 and the second supporting surface 520 to fix the circuit board 4.

[0089] As Figures 1-6 shown, a decorative member 7 is inserted through the housing 1. The decorative member 7 is convexly formed with a swing arm 71, and a decorative corner 72 is formed at the end of the swing arm 71.

[0090] The housing 1 is also formed with a third through hole 16 for the decorative corner 72 to pass through. An abutting portion 56 is formed on the periphery of the fixing seat 5, and the abutting portion 56 can abut against the swing arm 71, so that the decorative corner 72 can partially protrude from the housing 1, and the decorative corner 72 is prevented from detaching from the third through hole 16 by the abutting portion 56.

[0091] As Figures 1-6 shown, a second through hole 12 is also opened on the housing 1, and a pressing portion 8 is inserted through the second through hole 12. By pressing the pressing portion 8, the pressing portion 8 can abut against the button 41.

[0092] As Figures 1-6 shown, a lamp ring 9 is arranged on the periphery of the nail grinding portion 15, and the insertion terminal of the lamp ring 9 can be inserted into the pin socket 42. The light-transmitting plate of the lamp ring 9 is selected to use a semi-transparent material, which can effectively diverge the light, so that the light can be reflected more softly after being projected onto the reflecting surface, reducing the harm to the human eye.

[0093] As Figures 1-6 shown, an avoidance groove 14 is formed on the side wall of the installation groove 13 for the insertion terminals of the lamp ring 9 and the driving motor 3 to pass through.
