[0002] At present, the sharpening devices in the dental department are mainly used for periodontal manual instruments or surgical sharp instruments. However, since most of the instruments used in the oral cavity have narrow or short blades (the blade length is mostly less than 1 cm, the blade length of the curette is about 6 mm and the width is about 1.5 mm), and periodontal instruments have extremely high precision requirements for the blade angle, once the sharpening angle is wrong, at the very least, a lot of grinding and modification will be required to reduce the service life of the instrument, increase the risk of instrument breakage during clinical operation, and at worst, the instrument will be scrapped. Therefore, the current sharpening method is operated by personnel with certain sharpening experience, which has disadvantages such as low efficiency, high learning cost, and high technical sensitivity, and cannot meet the clinical requirements for fast and accurate sharpening.
[0003] While some existing manufacturers have produced angle-determining sharpening devices that can assist workers in sharpening instruments to a certain extent, there is still a problem that the angle of the instrument cannot be accurately fixed, which affects the sharpening effect of the instrument.

In a specific implementation, a telescopic frame 201 is horizontally inserted and mounted at both ends of the fixed box 2, the driving roller 3 is rotatably mounted on the end of the telescopic frame 201 away from the fixed box 2, and a plurality of fastening bolts 202 are disposed on the outside of the fixed box 2, the fastening bolts 202 penetrate into the fixed box 2 and abut against the side of the telescopic frame 201 for fixation. Therefore, the sharpening efficiency and the smoothness of the sharpening can be ensured by replacing the abrasive belt 4, and the use is convenient.
[0035] At the same time, a positioning frame 5 is movably installed on the base 1. The positioning frame 5 includes a mounting plate and two legs. The two legs are hinged on both sides of the fixing box 2. A fixing cylinder 6 for fixing the instrument to be sharpened is provided on the mounting plate of the positioning frame 5. A scale plate 7 is fixed on one side of the base 1. The scale plate 7 is semicircular, and one leg of the positioning frame 5 is hinged at the center of the scale plate 7. The side of the positioning frame 5 is slidably positioned with the scale plate 7. The specific cooperation is as follows: Figure 3 and Figure 4 As shown, a slider 501 is fixed to the side of the positioning frame 5, and a semicircular slot 701 is provided on the scale plate 7 for the slider 501 to slide into. The slot 701 is a semicircular groove, and the position of the scale plate 7 corresponding to the slot 701 is also provided with a scale line 702 for indicating the tilt angle of the positioning frame 5. The end of the slider 501, which is away from the positioning frame 5, extends out of the slot 701 and is threadedly engaged with a positioning bolt 502. The positioning bolt 502 abuts the side of the scale plate 7, and the bottom of the scale plate 7 has at least two fixing holes 703. The fixing holes 703 are used to fasten the scale plate 7 to the side of the fixed box 2. Therefore, the scale plate 7 can assist the positioning frame 5 in ensuring the sharpening angle.
[0036] The fixed barrel 6 is provided with an abutment block 601. A slot for receiving an instrument handle is defined on the side of the abutment block 601 facing the mounting plate. An adjustment screw 602 is rotatably mounted on the side of the abutment block 601 facing away from the slot. The adjustment screw 602 is threaded through the exterior of the fixed barrel 6 and secured with a screw cap. Thus, the distance between the slot of the abutment block 601 and the fixed barrel 6 can be adjusted by adjusting the screw 602, allowing instrument handles of varying sizes to be secured within the fixed barrel 6, providing a high degree of versatility.
[0037] In addition, in this embodiment, the upper and lower sections of the sanding belt 4 are respectively located at the upper and lower end surfaces of the fixed box 2, and the bottoms of the two legs of the positioning frame 5 are hinged to the middle of both sides of the fixed box 2, and the fixed tube 6 is located above the sanding belt 4.
[0038] The working principle of this utility model is as follows:
[0039] During use, the instrument can be placed in the fixed cylinder 6, and the abutment block 601 can be driven to move by rotating the adjusting screw 602 to fix the handle of the instrument.
