Abstract
A tool chucking device, especially an oscillation tool chucking device, includes at least one chucking unit which has at least one pin-type chucking element for clamping a treatment tool in an axial direction and at least one grip head arranged on the chucking element. The tool chucking device further includes at least one movement conversion unit which is designed to displace at least the grip head at least substantially along the axial direction into at least one direction different from the axial direction depending on the movement of the chucking element.
Claims13
A tool clamping device, comprising:
- at least one clamping unit having (i) at least one pin-shaped clamping element configured to chuck a working tool in an axial direction and (ii) at least one clamping head disposed on the clamping element;
- and
- at least one motion conversion unit, which in dependence on a motion of the clamping element at least substantially along the axial direction, is configured to move the clamping head in at least one direction differing from the axial direction.
A portable power tool, comprising:
- at least one tool clamping device including:
- at least one clamping unit having (i) at least one pin-shaped clamping element configured to chuck a working tool in an axial direction and (ii) at least one clamping head disposed on the clamping element;
- and
- at least one motion conversion unit, which in dependence on a motion of the clamping element at least substantially along the axial direction, is configured to move the clamping head in at least one direction differing from the axial direction.
