[0009] Preferably, the lower end of the connector is provided with an external thread, and the bottom inner wall of the first end cap is provided with an internal thread. The internal thread of the first end cap and the external thread of the connector are engaged to detachably fix the first end cap to the connector.

[0010] Preferably, a sliding groove is provided on the side wall of the first end cap, the top of the sliding groove extends to the top of the first end cap, and a protrusion is provided on the second end cap to cooperate with the sliding groove. The protrusion enters the sliding groove from the top of the first end cap, thereby fixing the second end cap to the first end cap.

[0011] Preferably, the bottom end of the slide is provided with several adjustment grooves, the adjustment grooves extend downward and the depth of the adjustment grooves gradually decreases from left to right, and the protrusion cooperates with different adjustment grooves to adjust the relative height between the second end cover and the first end cover.

[0012] Preferably, there are two grooves arranged opposite each other on the side wall of the first end cover, and the opposite grooves are symmetrically arranged at their centers. There are two protrusions arranged opposite each other on the inner side wall of the second end cover.

[0013] Preferably, the main body is further provided with a toggle switch and a speed adjustment button, and the main body is provided with a power supply device, a control panel and a motor.

[0014] Compared with existing technologies, this utility model nail grinder features a connector and locking device on the top of the main body, allowing for the detachable connection of various types of grinding heads. A first end cap can also be fitted onto the top of the main body, with a second end cap fitted over its outer side. Both the first and second end caps have openings on their sidewalls and tops that face the grinding heads. The width of these openings limits the contact area between the user and the grinding heads, improving safety. Furthermore, the first and second end caps act as dust covers, preventing nail clippings from flying everywhere. The relative height between the second and first end caps can be adjusted to regulate the thickness of the nail being ground. Different styles of first end caps can also be connected to the top of the main body, making the nail grinder versatile and suitable for various environments. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 3As shown, the armor grinder includes a body 1, with a connector 11 at the top and a connecting hole 111 in the middle. The connector 11 can be connected to different grinding heads. The connector 11 is sleeved on the outer wall of the locking device 13. The locking device 13 includes a clamping shaft 131 with its top facing the connecting hole 111 and a first thread 132 at its bottom. The connector 11 also has a second thread (not shown in the figure) that mates with the first thread 132. The inner diameter of the top of the connector 11 is smaller than the inner diameter of the bottom. When installing a grinding head, the grinding head is passed through the connecting hole 111 and the clamping shaft 131, and the connector 11 is tightened downwards to clamp the clamping shaft 131, thereby clamping the grinding head.

[0022] The lower end of the connector 11 has an external thread 12 on the body 1. The top outer wall of the connector 11 is fitted with a first end cap 2. The bottom inner wall of the first end cap 2 has an internal thread 22. The internal thread 22 of the first end cap 2 and the external thread 12 of the body 1 cooperate to fix the first end cap 2 detachably on the body 1.

[0023] The first end cap 2 has a first opening 21 on its side wall, opposite to the side wall of the grinding head, and a second opening 24 on its top, opposite to the top of the grinding head. A second end cap 3 is fitted over the first end cap 2. The second end cap 3 has a third opening 31 on its side wall, opposite to the first opening 21, and a fourth opening 32 on its top, opposite to the second opening 24. Users can use the side of the grinding head to grind their nails through the first opening 21 and the third opening 31, and can also use the top of the grinding head to grind their nails through the second opening 24 and the fourth opening 32. The width of each opening limits the contact area between the user and the grinding head, improving safety during use.

[0024] The first end cap 2 has a sliding groove 23 on its side wall, which is symmetrically arranged. The top of the sliding groove 23 extends to the top of the first end cap 2. The inner wall of the second end cap 3 has a corresponding protrusion 33 that cooperates with the sliding groove 23. The protrusion 33 enters the sliding groove 23 from the top of the first end cap 2, thereby fixing the second end cap 3 to the first end cap 2. The bottom of the sliding groove 23 has several adjustment grooves 231. The adjustment grooves 231 extend downward and gradually become shallower from left to right. The protrusion 33 cooperates with different adjustment grooves 231 to adjust the relative height between the second end cap 3 and the first end cap 2, thereby adjusting the width between the first opening 21 and the third opening 31 and the second opening 24 and the fourth opening 32, thereby adjusting the thickness of the nail polish.

[0025] The main body 1 is also equipped with a toggle switch and a speed adjustment button. Inside the main body 1, there is a power supply, a control panel and a motor. The power supply, control panel and motor are connected by wires. The toggle switch is connected to the power supply and the speed adjustment button is connected to the control panel. They are used to control the on / off state and speed of the armor grinder.

[0026] Example 2:

[0027] like Figures 4 to 5 As shown, the top of the first end cap 2 is provided with a through hole through the connector 11. The top of the first end cap 2 abuts against the top wall of the body 1. When the small grinding head is fixed in the connecting hole 111, the product as a whole can become a small grinding machine. The product has multiple functions and can be used in different environments.

[0028] This utility model nail grinder features a connector 11 and a locking device 13 on the top of the main body 1, allowing for the detachable connection of various types of grinding heads. A first end cap 2 can also be fitted onto the top of the main body 1, with a second end cap 3 fitted onto the outer side of the first end cap 2. Both the sidewalls and tops of the first and second end caps 2 and 3 have openings opposite to the grinding heads. The width of these openings limits the contact area between the user and the grinding head, improving safety. Furthermore, the first and second end caps 2 and 3 can act as dust covers, preventing nail clippings from flying everywhere. The relative height between the second end cap 3 and the first end cap 2 can be adjusted to regulate the thickness of the nail being ground. Different styles of first end caps 2 can also be connected to the top of the main body 1, making this nail grinder versatile and suitable for various environments.
