ABSTRACT:
A rotatable socket for supporting a tool for rotating in a head housing of a dental handpiece, includes a catch device which includes at least one catch member movable between a locking position for retaining a tool in the socket and an unlocking position for releasing the tool and a thumb actuated purchase. The purchase has a pressure surface that is movable from a position disengaged from each catch member to a position engaging each catch member, a cover member having a peripheral edge that is rigidly secured to the head housing, and the cover member has an elastically deformable portion movable through a stroke when pressure is applied to the purchase so that the deformable portion of the cover member will move through the stroke to cause the pressure surfaces to move each catch member to an unlocking position to release the tool from the socket.
