Detailed implementation mode

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. The implementation modes of the present invention include but are not limited to the following embodiments.

[0024] As Figure 1 、 2 shown, this embodiment provides a double - headed nail grinder, which includes a housing 1 with an internal storage cavity. The housing is divided into an upper cover 2 and a lower cover 3, and the upper cover 2 and the lower cover 3 are fixedly connected by snap - fit. Inside the housing, a nail grinding assembly for grinding nails, a shaving assembly for trimming the hair around the nails, and a control mechanism for controlling the operation of the nail grinding assembly or the shaving assembly are installed. The nail grinding assembly and the shaving assembly are respectively located on both sides inside the housing 1.

[0025] As Figure 3 shown, the nail grinding assembly includes a first motor 4 snap - connected inside the housing 1, a transmission shaft 5 connected to the output end of the first motor 4, a grinding head 6 connected to the end of the transmission shaft 5 away from the first motor 4, and a grinding head protective cover 7 sleeved outside the grinding head 6. The grinding head 6 is located outside the housing 1, and an outer cover 8 of the nail grinding assembly is provided outside the grinding head protective cover 7, and this outer cover is thread - connected or snap - connected to the housing 1. In this embodiment, the transmission shaft 5 is a hexagonal prism connecting rod.

[0026] As Figure 4 shown, the shaving assembly includes a second motor 9 snap - connected inside the housing 1. The output end of the second motor 9 is connected with an eccentric rod 10, and the end of the eccentric rod 10 is connected with a transverse eccentric rod 11. As Figure 5 shown, one end of the transverse eccentric rod 11 is provided with a through hole 13, the longitudinal diameter of this through hole 13 is greater than the transverse diameter, the end of the eccentric rod 10 passes through this through hole 13, and a central axis 12 is vertically passed through the middle position of the transverse eccentric rod 11, and this central axis 12 is fixed to the lower cover 3. The second motor 9 transmits kinetic energy to the transverse eccentric rod 11 through the eccentric rod 10. Under the restrictive action of the through hole 10 and the central axis 12, the transverse eccentric rod 11 moves back and forth horizontally.

[0027] At one end of the horizontal eccentric rod 11 that is not connected to the eccentric rod 10, a tool bit fixing seat 14 is installed. A replaceable tool bit 15 is installed on the tool bit fixing seat. A fixed tool bit 16 is disposed in close contact with the lower side surface of the tool bit 15. The fixed tool bit 16 is fixedly installed on the lower cover 3. The ends of both the tool bit 15 and the fixed tool bit 16 are serrated blades. Due to the transverse reciprocating motion of the horizontal eccentric rod 11, the tool bit 15 can also perform transverse reciprocating motion on the fixed tool bit 16, thereby realizing the shearing of hair. Further, in order to ensure the stability of the tool bit 15 during transverse reciprocating motion and enable the tool bit 15 to always be in close contact with the fixed tool bit 16 during motion, a fixing seat fastening spring 17 is installed between the tool bit fixing seat 14 and the lower cover 3.

[0028] The control mechanism includes a battery 18 disposed between the first motor 4 and the second motor 9 and capable of supplying electrical energy to the first motor 4 and the second motor 9. A circuit board 19 is disposed on the upper surface of the battery 18. A shaving button 20 and a nail grinding button 21 are disposed on the upper cover 2. The shaving button 20 and the nail grinding button 21 are connected to the circuit board 19 and are respectively used to control the switches of the second motor 9 and the first motor 4. The shaving button 20 and the nail grinding button 21 are fixed to the housing 1 through a fixing plate 22, and the fixing plate is an acrylic patch. Additionally, the battery 18 used in this embodiment is a rechargeable battery, and a charging interface 23 for the battery 18 is disposed on the housing 1; a lamp bead 24 for illumination during shaving operation is also installed on the housing 1.

[0029] During use, according to the user's selection, if nail trimming is required, the grinding head protective cover is opened, and the nail grinding button is pressed. The first motor starts to work and drives the grinding head to rotate through a transmission shaft, so that the nails can be trimmed and polished; if hair around the animal's nails needs to be trimmed, the shaving button is pressed, the second motor starts to work, the eccentric rod drives the horizontal eccentric rod to reciprocate swing on the horizontal plane, and then drives the tool bit to reciprocate on the upper side surface of the fixed tool bit. The combined action of the tool bit and the fixed tool bit can realize the shearing of hair. One end of the nail grinder provided by the present utility model is a nail grinding assembly for grinding nails, and the other end is a shaving assembly for trimming hair around animal nails, which can meet the diversified needs of users; both ends of the nail grinder provided by the present utility model are electric, and compared with traditional manual nail grinding tools, it is more time-saving and labor-saving to use.

[0030] The above embodiments are only one of the preferred embodiments of the present utility model and should not be used to limit the protection scope of the present utility model. Any meaningless changes or touch-ups made on the main design concept and spirit of the present utility model, as long as the technical problems solved are still the same as those of the present utility model, should be included in the protection scope of the present utility model.
