Abstract:
A chuck includes a body (10) having an engaging groove (121) for releasably receiving a bit (80). A sleeve (20) is mounted around and movable relative to the body (10) along a longitudinal axis of the body (10) between a coupling position in which the bit (80) is retained in the engaging groove (121) and a releasing position allowing removal or insertion of the bit (80). The sleeve (20) further includes an engaging section (26) that slideably abuts a coupling section (124) of the body (10). The engaging section (26) is engaged with the coupling section (124) to allow joint rotation of the body (10) and the sleeve (20) about the longitudinal axis. The sleeve (20) further includes a flange (204) with a frictional outer periphery (205) to provide friction when the sleeve (20) is manually rotated about the longitudinal axis by rotating the frictional outer periphery (205). Furthermore, the flange (204) can be gripped by a user to move the sleeve (20) to the releasing position.
