Abstract
Connector for rotary dental tools and the like, comprising a housing, a support sleeve rotatably journaled in the housing to receive a shaft of a dental tool, wherein the sleeve is in the form of a circumferentially closed tubular member that surrounds the shaft without any play, and clamping means between the sleeve and the shaft, for immobilizing the tool prior to imparting rotary movement thereto, the clamping means being elastically deformable in the radial direction, and short in comparison to the length of the sleeve. Two exemplary embodiments are disclosed, one including a mechanism that includes a follower and a clamping nut for the tool, while the other has an inner turbine wheel and a conical support ring with a collar and a biasing spring acting on the clamping means.
