Abstract
A quick clamping device for positioning an accessory device on a hand-held power tool such as an angle grinder. The quick clamping device includes a drive output unit for moving the accessory device about a drive output axis of the drive output unit. The quick clamping device further includes a retaining unit for retaining the accessory device on the hand-held power tool. The retaining unit has a retaining element. The retaining unit has a retaining parameter which changes in a retaining state, in particular in the event of a transition from a retaining state to a clamping state.
Claims19
A quick clamping device for arranging an accessory device on a hand-held power tool, comprising:
- an output unit configured to move the accessory device about an output axis of the output unit, and
- a retaining unit having a retaining element configured to retain the accessory device on the hand-held power tool,
- wherein the quick clamping device has a retaining state, in which the retaining unit is configured to retain the accessory device on the output unit and the retaining element is rotationally movable relative to the output shaft, and a clamping state, in which the retaining unit is configured to fix the accessory device to the output unit and the retaining unit is translationally movable relative to the output shaft,
- wherein, (i) in the retaining state, the retaining element is configured to exhibit a rotational movement relative to the output shaft about the output axis that is greater than the rotational movement of the retaining element relative to the output shaft about the output axis in the clamping state, and (ii) in the clamping state, the retaining element is configured to exhibit a translational movement relative to the output shaft about the output axis that is greater than the translational movement of the retaining element relative to the output shaft about the output axis in the retaining state.
