[0017] 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.
[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a nail polishing machine that is easy to store, including a base 1. A battery pack 4 is bonded to the inside of the base 1 using EVA foam single-sided film 2 and EVA foam double-sided film 3. The battery pack 4 is electrically connected to a main board 5. The EVA foam single-sided film 2 and EVA foam double-sided film 3 are positioned between the battery pack 4 and the inner wall of the base 1, providing fixation and cushioning for the battery pack 4. A base shell 7 is snapped into the inside of the base 1. The main board 5 is mounted on the bottom of the base shell 7 using self-tapping screws 6. The main board 5 has buttons 8, a knob housing 17, and a two-pin socket 12. A lens 18 is fixedly connected to the knob housing 17. Two receiving slots are provided inside the base shell 7, each containing a polishing pen 10 and a power cord 11. The main board 5 has a charging port for charging the battery pack 4. For charging, the two-pin socket 12 is matched with the power cord 11, allowing the power cord 11 to be inserted into the two-pin socket 12 to power the polishing pen 10. A strong magnet 9 is fixedly connected to the bottom of the base shell 7. A flip-top shell 13 is rotatably connected to the top of the base shell 7. An iron plate 14, made of stainless steel, is fixedly connected to the flip-top shell 13 using double-sided adhesive, facilitating its fixation. One end of the flip-top shell 13 is rotatably connected to the base shell 7, while the other end is a free end. The iron plate 14 is positioned on the free end of the flip-top shell 13, allowing it to be magnetically fixed using the magnetic attraction between the iron plate 14 and the strong magnet 9. Multiple placement seats 20 are fixedly connected to the top surface of the flip-top shell 13. (See reference...) Figure 4The placement base 20 is located on the back of the flip-top bottom shell 13, and the front is shaped like an insertion hole for placing the grinding head 15. The placement base 20 uses its own elasticity to lock and fix multiple grinding heads 15, thereby preventing the grinding heads 15 from falling off during carrying. Multiple grinding heads 15 are locked inside the multiple placement bases 20. The flip-top top shell 16 is locked to the top of the flip-top bottom shell 13. Multiple silicone feet 19 are fixedly connected to the bottom surface of the base 1. The multiple silicone feet 19 are adhered to the base 1 and can play a good anti-slip role.
[0019] When in use, flip the bottom cover 13 to open the base cover 7, take out the polishing pen 10 and power cord 11 from the base cover 7, then close the bottom cover 13 again and use the iron plate 14 and the super magnet 9 to magnetically fix it. Then open the top cover 16 and take out the polishing head 15 from the placement seat 20 on the bottom cover 13. Install the polishing head 15 on the polishing pen 10, and insert both ends of the power cord 11 into the polishing pen 10 and the two-pin socket 12 respectively. Operate by pressing the button 8 and the knob to polish the nails. After use, remove the power cord 11, put the power cord 11 and polishing pen 10 into the base cover 7, and put the polishing head 15 back into the placement seat 20. The overall size is small and can fix and accommodate multiple polishing heads 15, thus effectively improving the convenience of storage and carrying.
