Problems solved by technology

[0003] The mandrel assembly and its internal components have the characteristics of small size and high precision requirements. The chuck is driven to move left and right by applying external force to realize the loosening and clamping of the chuck to the bur. This is the prior art. However, due to the small size of the components, when the pressing part and the collet are transmitted to each other, the connection between the two often appears to be incoherent, which affects the clamping and replacement of the bur; and due to the connection and fit Incoherent, the resulting clamping of the chuck to the needle is unstable, prone to problems such as flying needles during use, and there is a great potential safety hazard

Embodiment Construction

[0022] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0023] Such as figure 1 and figure 2 As shown, a shaft assembly of a press-type dental high-speed turbine handpiece includes a shaft 1, a hollow cavity 11 is provided inside along the axial direction of the shaft 1, and a spring 2 and a chuck body 3 are provided from It is slidably arranged in the hollow cavity 11 from left to right; the hollow cavity 11 is provided with a mounting cone surface 110, and the inner diameter of the mounting cone surface 110 gradually decreases from left to right;

[0024] The chuck body 3 is a hollow structure composed of a pressing part 31, a clamping cone 32 and a bottom ring 33. The pressing part 31 is formed by the small end of the clamping cone 32 along the Axially extending to the right, the bottom ring 33 is formed by extending the large end of the clamping c...

Abstract

An assembly structure for a press-type dental high-speed turbine handpiece, including a mandrel, a hollow cavity is provided inside along the axial direction of the mandrel, a spring and a chuck body are slidably arranged on the In the hollow cavity; the clamping cone is adaptively matched with the installation cone surface, and several adjustment through holes are arranged on it along the taper direction of the clamping cone, and the adjustment through holes are connected to all Clamp the lateral and medial walls of the vertebral body as described above. The bur is easy to clamp and replace, and has high stability when clamping.

Description

technical field [0001] The invention relates to the field of dental handpiece equipment, in particular to an assembly structure for a press-type dental high-speed turbine handpiece. Background technique [0002] The bur of the pressing type dental high-speed worm handpiece of the prior art is replaced by pressing the corresponding button. For clamping, when it is necessary to take and place the bur, press the lower expansion part to open the clamping part, and then the bur can be taken and placed. [0003] The mandrel assembly and its internal components have the characteristics of small size and high precision requirements. The chuck is driven to move left and right by applying external force to realize the loosening and clamping of the chuck to the bur. This is the prior art. However, due to the small size of the components, when the pressing part and the collet are transmitted to each other, the connection between the two often appears to be incoherent, which affects the...
