[0028] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1-3 As shown, the dental handpiece with visualized handpiece of this embodiment comprises a body component 1, a handpiece component 2 and a needle 3, wherein the handpiece component 2 is mounted on the body component 1 and the needle 3 is mounted on the body component 2. The body component 1 comprises a body shell 11, and the handpiece component 2 comprises a handpiece shell 21, which is mounted on the body shell 11. The handpiece shell 21 is designed as a transparent shell, and the material of the handpiece shell 21 is transparent PPSU (polyphenylene sulfone tree), which has the characteristics of high temperature resistance, corrosion resistance, impact resistance and easy molding and processing.

[0030] Reference Figure 6-8 The head housing 21 is processed with a cylindrical sleeve portion 211, and one end of the sleeve portion 211 is processed with an inwardly concave positioning and connecting groove 213, and the cross section of the positioning and connecting groove 213 is square. Figure 5 and Fig. 9 A set groove 12 is processed at one end of the fuselage shell 11, and a protruding positioning connection column 13 is processed at the bottom of the set groove 12 on the fuselage shell 11, and the cross section of the positioning connection column 13 is square.
