DETAILED DESCRIPTION

[0025] The specific implementation of the technical solution is further described in detail below with reference to the accompanying drawings.

[0026] [Example 1]

[0027] like Figure 1-3 As shown, a hand-held electric nail grinder comprises an outer shell 1, a nail grinder grinding head 6, a nail grinder driving component 7 and an electric control element. The nail grinder driving component 7 and the electric control element are arranged in the outer shell 1, and the nail grinder grinding head 6 is detachably arranged at the output end of the nail grinder driving component 7. The electric control element can control the nail grinder grinding head 6 to work through the nail grinder driving component 7.

[0028] Specifically, the outer shell 1 is approximately rectangular in shape as a whole, with a machine head 3 formed at the front end and a grip 2 formed at the rear end. A person can hold the grip 2 to grind nails, and a nail grinder driving component 7 is placed in the machine head 3. The grip 2 has a accommodating cavity 4 for placing a nail grinder grinding head 6 and an electric control cavity 5 for placing electric control components. The number of accommodating cavities 4 is set to at least one, and each accommodating cavity 4 can accommodate a nail grinder grinding head 6. When the nail grinder grinding head 6 in use needs to be stored after use, the nail grinder grinding head 6 can be disassembled and placed in the accommodating cavity 4.

[0029] like Figure 3 The outer shell 1 shown includes a shell 1 8 and a shell 2 10, and the shell 1 8 and the shell 2 10 are both half shells. When the two are spliced ​​together, the outer shell 1 can be formed. The shell 1 8 and the shell 2 10 are respectively provided with a receiving groove 1 9 and a receiving groove 2 11. Similarly, the receiving groove 1 9 and the receiving groove 2 11 are both half grooves. When the shell 1 8 and the shell 2 10 are spliced ​​together, the receiving groove 1 9 and the receiving groove 2 11 cooperate to form a receiving cavity 4.

[0030] Furthermore, the open part of the accommodating chamber 4 has a necked portion 12, which is used to fix the nail grinder head 6 in the accommodating chamber 4. The inner diameter of the lower end of the nail grinder head 6 is adapted to the inner diameter of the necked portion 12. When the nail grinder head 6 is placed in the accommodating chamber 4, its upper end is placed outside the outer shell 1, and the lower end is clamped at the necked portion 12, so that the nail grinder head 6 is fixed on the outer shell 1.

[0031] like Figure 3 As shown, when shell 1 8 and shell 2 10 are spliced ​​together, they need to be connected and fixed to each other. Shell 1 8 is provided with a snap-fitting portion 13, and shell 2 10 is provided with a snap-fitting groove 14 adapted to snap-fitting portion 13. When shell 1 8 and shell 2 10 are spliced ​​together, snap-fitting portion 13 is placed in snap-fitting groove 14.

[0032] Furthermore, the housing 1 8 and the housing 2 10 may be connected by screws.

[0033] like Figure 2-4 As shown, a fixing part 15 is provided at the front end of the machine head 3, and the fixing part 15 is used to close the outer shell 1 and fix the output end of the nail grinder driving part 7. The front end of the output end of the nail grinder driving part 7 extends out of the machine head 3 through the fixing part 15 and is connected to the nail grinder grinding head 6.

[0034] Specifically, a fixing portion 16 is protruding from the peripheral side of the fixing member 15, and the fixing portion 16 is snapped into a fixing groove 17 formed in the machine head 3 to be fixed in the outer shell 1. Before the shell 1 8 and the shell 2 10 are spliced ​​together, the fixing portion 16 is sleeved on the output end of the nail grinder driving member 7, and then it is placed in the shell 1 8 or the shell 2 10, and the fixing portion 16 is placed in the fixing groove 17 at the same time, and then the other shell is spliced ​​to realize the assembly of the nail grinder.

[0035] Furthermore, the nail grinder driving member 7 is tiltedly arranged in the machine head 3, the straight line where the nail grinder driving member 7 is located forms an obtuse angle with the straight line where the hand grip 2 is located, and the nail grinder grinding head 6 is arranged on the tilted nail grinder driving member 7, which can better facilitate personnel to observe the situation where the nail grinder grinding head 6 contacts the nail.

[0036] like Figure 2 and Figure 3 As shown, the handheld electric nail grinder further comprises a cover plate 18 for closing the accommodating chamber 4 , and the cover plate 18 is arranged on the outer shell 1 .

[0037] Specifically, a second clamping portion 19 is protruding from the outer shell 1, and a second clamping groove 20 is formed on the inner wall of the cover plate 18. When the cover plate 18 is set on the outer shell 1, the second clamping portion 19 is placed in the second clamping groove 20. The cover plate 18 can prevent the nail grinder grinding head 6 from falling from the accommodating groove and can protect the nail grinder grinding head 6 from external contamination.

[0038] Furthermore, the cover plate 18 can be detachably mounted on the outer shell 1 by means of screws, and can also be slidably mounted on the outer shell 1 by means of cooperation between a sliding groove and a sliding block.

[0039] like Figure 3 and Figure 4 As shown, the electric control element includes a battery power supply 21 and a circuit board 22. The battery power supply 21, the circuit board 22 and the nail grinder driving component 7 are interconnected by wires. A switch button 23 for controlling the start and stop of the nail grinder driving component 7 is provided on the circuit board 22.

[0040] Furthermore, the outer shell 1 is provided with a battery flip cover 24 for enclosing a power supply battery, and the battery can be replaced by opening the battery flip cover 24 . A switch handle 25 movably abutting against the switch button 23 is also provided.

[0041] [Example 2]

[0042] The configuration of this embodiment is generally the same as that of Example 1, with the only difference being the configuration of the accommodating chamber 4. In this embodiment, the cover plate 18 is disposed on the outer shell 1, and cooperates with the outer shell 1 to form an accommodating chamber 4 for placing the grinding head 6 of the nail grinder. The grinding head 6 of the nail grinder can be directly placed in the accommodating chamber 4, making it convenient to carry the nail grinder outside.

[0043] The above shows and describes the basic principle and main features of the technical solution and the advantages of the technical solution. The technicians in this industry should understand that the technical solution is not limited by the above embodiments.
