[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] Example

[0022] like Figure 1-4As shown, this utility model provides a handheld dental polishing pen, including a housing 1, a slide 2, a cleaning component 3, and a polishing component 4. The slide 2 is fixedly connected to both sides of the inner wall of the housing 1, the cleaning component 3 is placed on the top of the housing 1, and the polishing component 4 is slidably connected to the slide 2. The slide 2 is fixedly connected to both sides of the inner wall of the housing 1 to form a stable sliding track, making the sliding of the polishing component 4 smoother, reducing vibration and improving operating accuracy, while also enhancing the overall structural strength.

[0023] The grinding assembly 4 includes a grinding ring 9 and a grinding slider 10. The inner wall of the grinding ring 9 has a grinding groove, and the grinding slider 10 is slidably connected to the grinding ring 9. The cleaning assembly 3 is located on top of the housing 1, achieving efficient cleaning coverage through its high-position layout. This facilitates simultaneous removal of debris and cooling of the work area during grinding, reducing the risk of secondary contamination. Guided by the slide rail 2, the grinding assembly 4 can be flexibly adjusted to adapt to different dental operation angles, improving clinical applicability. The grinding groove on the inner wall of the grinding ring 9 slides in conjunction with the grinding slider 10, ensuring a stable linear movement trajectory of the grinding head 18, preventing deviation, and improving grinding uniformity.

[0024] The grinding assembly 4 also includes a drive bracket 11, a drive slide plate 12, a drive spring 13, and a drive wheel 14. The drive bracket 11 is fixed to both ends of the grinding slider 10. The drive slide plate 12 is slidably connected to the inner wall of the drive bracket 11. The two ends of the drive spring 13 are respectively connected to the drive bracket 11 and the drive slide plate 12. The drive wheel 14 is rotatably connected to the middle of the drive slide plate 12 and is placed in the grinding groove. The drive spring 13 applies adaptive pressure to the drive wheel 14 through the drive slide plate 12, making it fit tightly against the inner wall of the grinding groove to achieve stable power transmission. The rotation of the drive wheel 14 can adjust the grinding speed to adapt to dental materials of different hardness.

[0025] The grinding assembly 4 also includes a telescopic frame 15, a clip 16, and a grinding rod 17. The telescopic frame 15 is mounted on top of the grinding slider 10, and the clip 16 engages the grinding rod 17 and the telescopic frame 15. The grinding rod 17 and the telescopic frame 15 are detachably connected. The clip 16 enables quick assembly and disassembly of the grinding rod 17 and the telescopic frame 15, simplifying the replacement process. The telescopic frame 15 supports length adjustment of the grinding head 18, facilitating access to narrow areas of the oral cavity and improving operational flexibility.

[0026] Multiple grinding rods 17 are equipped with different grinding heads 18 at their bottoms. By changing the grinding rods 17 with different grinding heads 18, various dental operations such as cutting, polishing, and shaping can be adapted to reduce the number of instruments and lower costs.

[0027] The cleaning assembly 3 includes a cleaning bracket 5, a cleaning telescopic rod 6, a cleaning support rod 7, and cleaning nozzles 8. The cleaning bracket 5 is mounted on the top of the housing 1. The cleaning telescopic rod 6 is mounted on the end of the cleaning bracket 5 furthest from the housing 1. The cleaning support rod 7 is mounted on the extended end of the cleaning telescopic rod 6. Multiple cleaning nozzles 8 are mounted on the cleaning support rod 7. The cleaning telescopic rod 6 can adjust the extension length and angle of the cleaning support rod 7. Combined with the multi-nozzle design, it achieves wide-area coverage, precisely rinses debris, and cools the polishing area, improving treatment safety and patient comfort.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
