Abstract
A tool chuck may include a chuck body defining a longitudinal axis. A sleeve may be mounted on the chuck body for movement between a first axial position and a second axial position. A clutch part provided on the sleeve. The clutch part may engage with a cooperating clutch part when the sleeve is in the second axial position. The clutch part may have a working surface that faces in a direction perpendicular to the longitudinal axis.

1-12. (canceled)
A power driver including a tool chuck, the power driver comprising:
- a chuck body defining a longitudinal axis;
- a sleeve mounted directly on the chuck body for movement between a first axial position and a second axial position;
- a switch for switching on a motor of the power driver;
- a link between the sleeve and the switch;
- and
- wherein moving the sleeve into the second position, switches on the motor of the power driver.
A power driver including a tool chuck, the power driver comprising:
- a chuck body defining a longitudinal axis;
- a first sleeve mounted on the chuck body;
- a second sleeve mounted on the chuck body, the second sleeve supporting a clutch part, the second sleeve being moveable relative to the first sleeve between a first axial position in which the first and the second sleeves are rotatable with the chuck body, a second axial position in which the clutch part engages with a cooperating clutch part;
- and a spring that biases the second sleeve toward the first axial position, wherein the spring is captured between the chuck body and the second sleeve;
- a switch for switching on a motor of the power driver;
- a link between the sleeve and the switch;
- and
- wherein moving the sleeve into the second position, switches on the motor of the power driver.
A power driver having a tool chuck, the power driver comprising:
- a chuck body;
- a sleeve mounted directly on the chuck body for movement between a first axial position and a second axial position;
- a clutch part provided on the sleeve;
- a switch for switching on a motor of the power driver;
- a link between the sleeve and the switch;
- wherein, when the sleeve is in the second axial position the clutch part engages with a cooperating clutch part, and the clutch part and the cooperating clutch part are movable relative to each other in a radial direction to limit torque applied during a chuck actuating process;
- and
- wherein moving the sleeve into the second position, switches on the motor of the power driver.
