Abstract
A chuck body has one end for connection to a power tool, and another end from which a plurality of jaws project. A sleeve turnably surrounds the body and jaws and is operative, when turned in one direction, for moving the jaws inwardly towards one another into engagement with a tool bit that is located between them. A plate spring is mounted at the one end of the body and has a circumferential marginal portion which engages and frictionally locks the sleeve when the latter is turned in the aforementioned one direction.
