Abstract
A tool holder, particularly a hand-held power tool holder, is provided for an oscillating and/or rotational drive of at least one insertion tool. The tool holder includes at least one holder-side fastening element that is provided at least substantially for a coupling with the at least one insertion tool. The tool holder also includes at least one bearing unit provided for movably mounting the at least one holder-side fastening element in a movement at least partially deviating from an axial direction. The movement at least partially deviating from the axial direction of the at least one fastening element is provided at least substantially for creating a fastening force in the axial direction.
Claims7
A hand-held power tool, comprising:
- a drive shaft configured to be driven with a driving motion by the power tool;
- a tool holder configured to drive at least one insert tool in an oscillating and/or rotational manner, the tool holder including:
- at least one fastening element configured at least substantially to couple with the at least one insert tool;
- at least one further fastening element that is fixed to the drive shaft and configured to at least substantially pass through and geometrically engage with at least one fastening recess of the at least one insert tool so as to radially and circumferentially secure the at least one insert tool to the tool holder and to transmit the driving motion of the drive shaft to the at least one insert tool via the geometric engagement;
- and
- at least one bearing unit configured to mount the at least one fastening element so as to be movable into a movement which deviates at least in part from an axial direction,
- wherein the movement, which deviates at least in part from the axial direction, of the at least one fastening element is configured at least substantially to generate a fastening force in the axial direction.
