[0002] With the booming development of the manufacturing industry and people's continuous pursuit of quality of life, electric polishing devices are playing an increasingly crucial role in many fields. In industrial manufacturing, electric polishing devices can significantly improve the appearance quality and performance of products with their efficient and precise polishing capabilities. In daily life, from the aesthetic polishing of wooden furniture to the exquisite polishing of jewelry, electric polishing devices also provide convenience for people to create high-quality details in their lives.

[0003] A novel portable polishing machine, disclosed in Publication No. CN211661774U, includes a polishing machine body with a switch button for starting and stopping the machine, as well as a housing. This device allows for high and low speed adjustment according to the working environment, with stepless speed control via a switch, making operation convenient and quick. A self-locking device prevents damage caused by children or unintentional starting of the machine. However, after use, the device cannot be folded away, has a fixed overall structure, is bulky, inconvenient to carry and store, and occupies space. Furthermore, the polishing components are exposed without effective protection, easily accumulating dust and other contaminants, affecting subsequent polishing. It is also easily damaged by accidental bumps or pressure, shortening its service life.

[0004] Therefore, it is necessary to design a portable electric polishing device that can be rotated to unfold for polishing and then folded up for protection and fixation after use, making it easy to carry, use and store, saving space and extending its service life. Utility Model Content

[0005] To overcome the shortcomings of the current device, such as its inability to be folded up after use, its fixed overall structure, large size, inconvenience in carrying and storing, its space-consuming nature, and the fact that its polishing components are exposed and lack effective protection, easily accumulating dust and other contaminants, affecting subsequent polishing, and being easily damaged by accidental bumps or pressure, thus shortening its service life, this utility model provides a portable electric polishing device that can be rotated to unfold for polishing and then folded up for protection and fixation after use, making it easy to carry, use, and store, saving space, and extending its service life.

[0006] The technical solution is as follows: A portable electric polishing device includes a connecting block, a cover plate, a locking block, a buckle, a button, a rotating block, a protective frame, a polishing disc, a connector, a button cover, a motor, a first torsion spring, an adjustment assembly, and a fixing assembly.

[0024] A portable electric polishing device, such as Figures 1-7 As shown, the assembly includes a connecting block 1, a cover plate 2, a locking block 3, a buckle 4, a button 5, a rotating block 7, a protective frame 8, a polishing disc 9, a connector 91, a button cover 10, a motor 15, a first torsion spring 17, an adjustment assembly, and a fixing assembly. The connecting block 1 is rotatably connected to the cover plate 2 at its right center. The upper left side of the cover plate 2 is connected to two locking blocks 3, each with a groove on its right side for easy locking and fixing. The upper right side of the connecting block 1 is rotatably connected to two buckles 4, and the front center of the connecting block 1 is slidably connected to the button 5. The left side of the connecting block 1 is rotatably connected to the rotating block 7, and the left center of the rotating block 7 is rotatably connected to the connector 9. 1. A protective frame 8 is connected to the left side of the rotating block 7. The protective frame 8 is rotatably connected to the connector 91. A polishing disc 9 is snapped into the left side of the connector 91. A button cover 10 is threadedly connected to the left side of the connector 91. A motor 15 is connected to the inner left side of the rotating block 7. The motor 15 and the processor are electrically connected through a control module. The output shaft of the motor 15 is connected to the connector 91. Two first torsion springs 17 are connected to the connector 1, one in front and one behind, of the buckle 4. An adjustment component for adjusting the polishing angle is provided between the connector 1 and the rotating block 7. A fixing component for fixing the device after it is folded up is provided on the lower right side of the cover plate 2.

[0025] like Figures 1-3 As shown, the adjustment assembly includes a knob 6, a first gear 11, a second gear 12, a rotating shaft 13, and a plug rod 14. The rotating shaft 13 is rotatably connected to the inner left side of the connecting block 1, and the knob 6 is slidably connected to the front of the rotating shaft 13. The outer side of the knob 6 is provided with anti-slip texture for easy anti-slip. The lower right side of the rotating block 7 is connected to two first gears 11, and the front and rear parts of the rotating shaft 13 are both connected to the second gears 12. The second gears 12 mesh with the first gears 11 on the same side. The plug rod 14 is connected to the inner front side of the connecting block 1, and the plug rod 14 is movably engaged with the knob 6.

[0026] like Figure 1 , Figure 5 and Figure 7 As shown, the fixing component includes a limiting block 16 and a second torsion spring 18. The lower right part of the cover plate 2 is rotatably connected to the limiting block 16. The limiting block 16 is L-shaped to facilitate limiting. Two second torsion springs 18 are connected between the limiting block 16 and the cover plate 2.

[0027] When polishing is required, this device can be used. Carry the device to the designated area, then rotate the limiting block 16 to disengage from the protective frame 8. The second torsion spring 18 deforms. Then, rotate the connecting block 1 and the rotating block 7 to open, causing the latch 4 to rotate. This allows the groove on the latch 4 to engage with the latch block 3, fixing the angle of the connecting block 1. Then, according to the polishing requirements, use the device directly for polishing, or manually pull the knob 6 to disengage from the insertion rod 14 to unlock it. Then, rotate the rotating shaft 13 via the knob 6. The anti-slip texture provides anti-slip protection, thereby driving the second gear 12 to rotate. The second gear 12 meshes with the first gear 11. The combined motion causes the rotating block 7 to rotate, thereby adjusting the angle of the polishing disc 9. After adjusting to the appropriate angle, press the knob 6 to engage with the insertion rod 14 for fixation. Then, pick up the device so that the polishing disc 9 contacts the item to be polished, and press the button 5. The processor starts the motor 15 through the control module, which drives the connecting part 91 to rotate, causing the polishing disc 9 and the button cover 10 to rotate and polish the item. Simultaneously, you can move the device by hand to polish different positions. The protective frame 8 provides protection, allowing you to adjust the angle of the rotating block 7 and the polishing disc 9 to polish the item, making it suitable for different applications. To improve polishing efficiency, after polishing, press button 5 again to turn off motor 15. If adjusting the angle, pull knob 6 to disengage from rod 14 to unlock. Then, rotate shaft 13 in the opposite direction using knob 6, which in turn drives second gear 12 to rotate in the opposite direction. Second gear 12 meshes with first gear 11, causing rotating block 7 to rotate in the opposite direction and reset. Press knob 6 to engage with rod 14 for fixation. Then, pull buckle 4 to rotate and disengage from block 3, causing first torsion spring 17 to deform. Rotate connecting block 1, rotating block 7, protective frame 8, and polishing disc 9 to retract, and then release. The buckle 4, the first torsion spring 17 rotates back to its original position, the buckle 4 rotates to reset, then the limiting block 16 is pulled to rotate, the second torsion spring 18 deforms, then the connecting block 1 and the rotating block 7 continue to rotate, so that the protective frame 8 contacts the cover plate 2, then the limiting block 16 is released, the second torsion spring 18 rotates back to its original position, the limiting block 16 rotates to reset and fix the protective frame 8, and then the device can be folded up. The limiting block 16 is L-shaped, so the device can be rotated to unfold for polishing, and after use the device can be folded up for protection and fixation, which is convenient to carry, use and store, saves space and extends service life, and then the device can be taken away.

[0028] When the polishing disc 9 is damaged during use, it can be removed by rotating the knob cover 10. Then, the polishing disc 9 can be removed and replaced. The new polishing disc 9 is then snapped into the connector 91. The knob cover 10 is then brought into contact with the connector 91, and the knob cover 10 is rotated to fix it in place. The polishing disc 9 can then be used again. This allows for the installation and use of the polishing disc 9 for polishing, making it easy to install, remove, and replace, reducing maintenance costs, and providing convenience.
