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.
Claims9
A tool chuck comprising:
- a chuck body defining a longitudinal axis;
- a sleeve mounted on the chuck body for movement between a first axial position and a second axial position;
- and
- a clutch part provided on the sleeve, the clutch part engaging with a cooperating clutch part when the sleeve is in the second axial position, the clutch part having a working surface that faces in a direction perpendicular to the longitudinal axis, and
- wherein the working surface faces the longitudinal axis.

1 more element
A tool chuck 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, and
- a second axial position in which the clutch part engages with a cooperating clutch part,
- wherein the clutch part has a ramped profile for driving the cooperating clutch part in a direction parallel to the longitudinal axis.
