Abstract
A locking device for a drive shaft of a rotating tool member of a working tool includes a securing element fixedly connected to the drive shaft of the rotating tool member. A locking bolt has a longitudinal axis and is axially moveable between a locking position and a release position. The securing element has at least one catch opening for receiving the locking bolt in the locking position. An actuating element is positioned adjacent to the locking bolt. A spring element has a first end and a second end whereby the first end is connected to the actuating element. The second end projects into the travel path of the locking bolt and engages the locking bolt for moving it into the locking position or into the release position when the actuating element is operated.
