摘要： Chuck (20) for use with a driver having a rotatable shaft, including a body (26) and jaws (28) slidably positioned in angled passageways (30) formed in the body (26). The chuck (20) further includes a nut (60) rotatably mounted relative to the body (26) and in engagement with threads (62) on the jaws (60). A generally cylindrical sleeve member (22) is disposed in driving engagement with the nut (60) and overlying the nose section (23) of the body (26) so that when the sleeve member (22) is rotated with respect to the body (26), the jaws (28) will be moved thereby to grip the shank of a tool. A pawl member (80) is biased to engage the sleeve member (22) and is disposed selectively rotatably with respect to the body (26). When the nut (60) is tightened, the pawl member (80) can be disposed to become nonrotatable with respect to the body (26) and restrains the nut (60) from loosening during vibration of the chuck (20) in use.

摘要： A chuck (30) with a generally cylindrical body (34) has a gripping mechanism (36) that is actuatable to a closed position in which the gripping mechanism (36) retains a tool with respect to the body (34). An annular nut (66) has a threaded portion (68) in threaded engagement with the gripping mechanism (36) so that rotation of the nut (66) in a closing direction actuates the gripping mechanism (36) to a closed position and rotation of the nut (66) in an opening direction, opposite the closing direction, actuates the gripping mechanism (36) to an open position. One of the nut (66) and the gripping mechanism (36) includes a rotational stop (78) which, when the gripping mechanism (36) reaches a predetermined position while being actuated by rotation of the nut (66) in the opening direction, abuts the other of the nut (66) and the gripping mechanism (36) in a rotational direction with respect to the axis (52) of the body (34) to oppose further rotation of the nut (66).
