[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-2 A portable nail polishing machine includes a body 1, a polishing pen 2, and a polishing head 7. The polishing pen 2 is electrically connected to the body 1 via a wire. A fixing component 3 is fixedly connected to the front side wall of the body 1. The fixing component 3 includes a positioning plate 31. Two positioning plates 31 are fixedly connected to the left side wall of the body 1 and are symmetrically distributed. The positioning plates 31 are provided with positioning holes inside. The diameter of the positioning holes is larger than the diameter of the polishing pen 2. The front side walls of the two positioning plates 31 are threaded with a positioning bolt 32 extending into the interior of the bolt. The rear side walls of the positioning bolts 32 are fixedly connected with positioning anti-slip sleeves.
[0025] The polishing pen 2 has an internal mounting cavity 4. A micro drive motor 5 is fixedly connected to the inner wall of the mounting cavity 4, extending to its bottom. A connecting frame 6 is fixedly connected to the output shaft of the micro drive motor 5 and slidably connected to its bottom. The bottom of the polishing pen 2 has an annular groove that matches the movement trajectory of the connecting frame 6. The top of the polishing head 7 has a snap-fit frame 8 that extends into the connecting frame 6. A snap-fit component 9 is movably connected to the inner wall of the snap-fit frame 8. The front and rear sides of the snap-fit component 9 extend to the front and rear sides of the connecting frame 6, respectively. The snap-fit component 9 includes a snap-fit plate 91. Two snap-fit plates 91 are slidably connected to the inner wall of the snap-fit frame 8 and are symmetrically distributed front and rear. A compression spring 92 is fixedly connected between the two snap-fit plates 91. A snap-fit shaft 93 is fixedly connected to the opposite sides of the two snap-fit plates 91. The front and rear side walls of the connecting frame 6 have snap-fit through holes that match the snap-fit shaft 93. The opposite sides of the two snap-fit shafts 93 extend to the front and rear sides of the connecting frame 6, respectively.
[0026] When in use, insert the polishing pen 2 into the positioning holes inside the two positioning plates 31. Then rotate the two positioning bolts 32 to move them backward. The positioning bolts 32 move backward and contact the polishing pen 2, thereby squeezing and fixing the polishing pen 2, thus completing the limiting and fixing of the polishing pen 2.
[0027] With the help of external long rods or other tools, the two snap-fit shafts 93 are pressed against each other. At this time, with the cooperation of the compression spring 92, the two snap-fit plates 91 move relative to each other until the opposite sides of the two snap-fit shafts 93 move to be flush with the left and right side walls of the snap-fit frame 8. At this time, the grinding head 7 is pulled down to move the snap-fit frame 8 out of the inside of the connecting frame 6, thus completing the disassembly of the grinding head 7.
[0028] It is worth noting that the body 1 mentioned in this application document is externally connected to a control switch and a drive power supply. A charging interface is provided on the rear side wall of the body 1. Both the body 1 and the micro drive motor 5 are conventional and known devices. The standard parts used in this application document can be purchased from the market. The specific connection methods of each part are all connected by conventional means such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. The contents not described in detail in the description belong to the prior art known to those skilled in the art, and will not be described in detail here.
[0029] In summary, this portable nail polisher, through the setting of the fixing component 3, allows for easy and convenient carrying of the polishing pen 2. First, the polishing pen 2 is inserted into the positioning holes inside the two positioning plates 31. Then, through the cooperation of the positioning bolts 32, the positioning bolts 32 move backward to contact the polishing pen 2, thereby squeezing and fixing the polishing pen 2. This achieves the purpose of easily securing and carrying the polishing pen 2 without relying on fixing ropes or tape for temporary fixation. The fixing effect is good, improving the practicality of the device. Through the setting of the snap-fit component 9, when the polishing head 7 needs to be disassembled and replaced, the two snap-fit shafts 93 are squeezed relative to each other using external long rods or other tools. At this time, under the cooperation of the compression spring 92 and the snap-fit plate 91, the two snap-fit components... The shafts 93 move relative to each other until the opposite sides of the two locking shafts 93 are flush with the left and right side walls of the locking frame 8. At this time, the grinding head 7 is pulled down to move the locking frame 8 out of the inside of the connecting frame 6, thereby facilitating the disassembly of the grinding head 7. The user does not need to remove the fixing screws one by one, making disassembly more convenient and further improving the practicality of the device. This solves the problem that most traditional nail polishing machines cannot fix the polishing pen and can only rely on fixing ropes or tape to temporarily fix the polishing pen, which easily causes the polishing pen to fall off and has a poor fixing effect, making it inconvenient for users to carry. Secondly, when disassembling and replacing the grinding head, the user needs to remove the fixing screws one by one, which is a cumbersome disassembly.
