[0002] Diamond turning needles are an important dental instrument. Existing diamond turning needles can not only meet the basic use needs of processing teeth, but also realize the vertical positioning function of tooth occlusion, thereby avoiding the problem of excessive horizontal dimension during tooth preparation. However, the spacing between the vertical positioning structures of tooth occlusion is fixed, so it can only be applicable to the vertical positioning needs of teeth of a single thickness. If you want to realize the vertical positioning needs of teeth of various thicknesses, you need to prepare vertical positioning structures of various sizes, which will not only increase the cost of users, but also bring great inconvenience to people's use.

[0003] For example, the utility model with announcement number CN 204092215 U discloses a diamond turning needle for clinical tooth preparation. In the technical solution of this patent, the vertical positioning function of the tooth occlusion is performed by the cooperation of a first retaining ring and a second retaining ring arranged on the needle body. Since the first retaining ring is fixedly arranged at the front end of the needle body and the second retaining ring is fixedly arranged at the rear end of the needle body, the spacing between the first retaining ring and the second retaining ring is fixed, which results in the device being only suitable for the vertical positioning requirements of the tooth occlusion of a single thickness.
