Abstract
A chuck () has a body (), a plurality of jaws (), and a rotatable nut (). A sleeve () is rotatable between a first rotational position and a second rotational position with respect to the nut. An annular array of first teeth () are non-rotatable with respect to the body. One or more second teeth () are non-rotatable with respect to the nut and axially movable with respect to the body. When the teeth engage, they resist the nut's rotation in the opening direction. An engagement between the sleeve and the one or more second teeth moves the one or more second teeth out of engagement with the first teeth when the sleeve moves from the second rotational position to the first rotational position and moves the one or more second teeth into engagement with the first teeth when the sleeve moves from the first rotational position to the second rotational position.
