Abstract:
The invention is based on a spindle locking device, in particular a hand tool spindle locking device having a spindle (12a-c), a clamping ring (14a-e) and at least one clamping piece (16a-c) which connects the spindle (12a-c) and the clamping ring (14a-e) together for conjoint rotation in at least one operating state. The invention proposes that the spindle locking device has at least one magnetic means (18a-e) that exerts a force on the clamping piece (16a-c) in at least one operating state.
