Tensioning mechanism for a dental handpiece and dental handpiece with the use of the mechanism

摘要

Disclosed is a clamping mechanism for a dental handpiece as well as a dental handpiece with the tensioning mechanism. In the case of the clamping mechanism, a sufficient clamping function for the tensioning mechanism is provided by the elastically deformable type and can be secured by reducing a axial outlet of a column-like turning tool for a dental treatment or care of in the case of a holding part of the dental handpiece, when the turning tool is held by means of a rotor on the holding part of the dental handpiece. The tensioning mechanism holds the columnar turning tool for a dental treatment or care, which with an annular rotor of the dental handpiece is rotatable. The tensioning mechanism is characterized by an annular clamping element, which has a cylindrical base region, in which the annular rotor is attached or integrally in one piece and, by means of an elastic tension element with a clamping lock to engage in a clamping recess, which, in a base end of the turning tool is designed. The tensioning mechanism makes it possible for the turning tool, in a simple manner by the annular rotor to be removed, specifically by means of elastic deformation of the elastic clamping piece against an elastic force of the elastic clamping piece, in order to lock the clamping of the recess to be disengaged.
