It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0042] like Figures 1 to 7 As shown, this embodiment provides a multifunctional electric nail trimmer, including:

[0043] The machine body 1 is equipped with a motor 11;

[0044] At least two tool heads, including a nail-grinding head 3 and a nail-trimming head 2; and,

[0045] The quick-release assembly includes a first connector 111 disposed on the output shaft of the motor 11 and a second connector 4 disposed on each of the tool heads; the motor 11 drives the tool heads to work through the first connector 111 and the second connector 4.

[0046] In some specific implementations, such as Figure 4 and Figure 5As shown, the first connector of the first interface is a cross-shaped protrusion, and the second connector 4 is a cross-shaped groove. The cross-shaped protrusion and groove facilitate quick assembly by the user, and the cross-shaped protrusion, by engaging with the cross-shaped groove, enables the motor 11 to drive the tool head to operate stably. The first connector and the second connector 4 of the first interface can also use other structures to achieve the fit.

[0047] In some specific implementations, such as Figures 3 to 5 , Figure 9 As shown, in order to make the connection between the tool head and the body 1 more secure and the tool head work more stably, the quick-release assembly also includes a first snap-fit ​​part disposed on the body 1 and a second snap-fit ​​part disposed on the tool head, wherein the second snap-fit ​​part and the first snap-fit ​​part snap-fit ​​each other.

[0048] In some specific embodiments, the body 1 is provided with an annular protrusion 12, and the annular protrusion 12 is provided with a receiving groove. The first connector 111 on the output shaft of the motor 11 is located in the receiving groove; specifically, the opening of the receiving groove is arranged facing the second connector 4.

[0049] An annular step 13 is provided around the outer side of the annular protrusion 12; the tool head is provided with an annular socket groove 5, and the second connector 4 is located in the annular socket groove 5;

[0050] When the second connector 4 is connected to the first connector 111, the annular sleeve groove 5 is fitted on the outside of the annular protrusion 12 and its end abuts against the annular step 13.

[0051] The above embodiments may also include an annular protrusion 12 on the tool head and an annular sleeve groove 5 on the machine body 1.

[0052] In some specific embodiments, the first engaging portion is a locking block 121 disposed on the outer side wall of the annular protrusion 12, and the second engaging portion is a locking groove 52 disposed on the inner side wall of the annular sleeve groove 5. The inner side wall of the annular sleeve groove 5 is also provided with a guide groove 51 communicating with the locking groove 52. When the tool head is installed onto the machine body 1, the locking block 121 is aligned with the entrance of the guide groove 51. When the locking block 121 slides to the bottom along the guide groove 51, the tool head is rotated forward relative to the machine body 1 to allow the locking block 121 to enter the locking groove 52. Specifically, the locking groove 52 and the guide groove 51 are arranged perpendicularly to each other, thereby preventing the locking block 121 from axially disengaging from the locking groove 52 and making the tool head more securely engaged with the machine body 1.

[0053] To further securely engage the slot 52 and the locking block 121, a backstop block 521 is provided within the slot 52, and a backstop groove 122 is provided on the locking block 121. The backstop block 521 restricts the reverse rotation of the locking block 121 by engaging within the backstop groove 122. Specifically, the annular protrusion 12 or the annular sleeve groove 5 has a certain degree of elasticity, thereby facilitating the movement of the backstop block 521 in and out of the backstop groove 122 when the locking block 121 moves in and out of the slot 52.

[0054] In some specific implementations, such as Figures 6 to 9 As shown, the nail grinding head 3 includes a grinding head 33 chuck and a grinding head 33. The second connector 4 and the annular sleeve groove 5 are both disposed on the grinding head 33 chuck. The grinding head 33 is disposed at the end away from the annular sleeve groove 5 and is detachably connected to the grinding head 33 chuck. Different grinding heads 33 can perform different levels of fineness or smoothness grinding on the nails, or different grinding heads 33 may have different diameters. Therefore, the grinding head 33 and the grinding head 33 chuck are detachably connected, making it easy to replace different grinding heads 33 as needed.

[0055] In one specific implementation, the grinding head 33 has a clamping groove 32 on its chuck, and a plug 331 inserted into the clamping groove 32 on the grinding head 33. The grinding head 33 also has a locking member 31, which is threadedly connected to the grinding head 33 chuck and has a clearance hole for the plug 331 to pass through. The locking member 31 locks the plug 331 in place by driving the clamping groove 32 to contract. Specifically, the clamping groove 32 is formed by several clamping arms, each with an arc-shaped structure at its upper end. The clamping arms are fixedly connected to the grinding head 33 chuck. During installation, the locking member 31 is first loosened, then the plug 331 is inserted into the clamping groove 32 through the clearance hole, and finally the locking member 31 is tightened. The locking member 31 has a conical groove for driving the clamping arms closer together. A first bearing 34 is provided between the annular sleeve groove 5 and the second connector 4, so that the second connector 4 can rotate relative to the annular sleeve groove 5.

[0056] As a specific implementation method, such as Figures 1 to 3 As shown, the nail clipper head 2 includes a blade 22, a nail clipper head housing 21, and a second connector 4. The annular sleeve groove 5, the blade 22, and the second connector 4 are all disposed within the nail clipper head housing 21. One end of the second connector 4 is connected to the first connector 111, and the other end of the second connector 4 is connected to the blade 22, thereby driving the blade 22 to rotate relative to the nail clipper head housing 21. A second bearing 23 is provided between the blade 22 and the nail clipper head housing 21.

[0057] In some specific embodiments, the motor 11 is a geared motor 11. The body 1 is also provided with a switch button 15 for controlling the motor 11, and the body 1 is provided with a battery 14 electrically connected to the motor 11 to supply power to the motor 11. A charging port can be provided on the outer shell of the body 1.

[0058] Working principle explanation:

[0059] When nail trimming is needed, the nail clipper head 2 can be installed onto the body 1. The second connector 4 on the nail clipper head 2 connects to the first connector 111 on the body 1. By rotating it forward, the slot 52 on the nail clipper head 2 engages with the locking block 121 on the body 1, allowing the motor 11 to drive the blade head 22 of the nail clipper head 2 to rotate stably. When nail filing is needed, the nail clipper head 2 can be quickly removed by rotating it in the opposite direction and pulling it away from the body 1. The nail filing head 3 can be quickly installed using the same installation method.

[0060] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model.
