Beschreibung
Zusammenfassung:	A shaft locking device for a motor-driven, hand-guided work tool spindle has a driven member fixedly connected thereto, a freewheel with locking members, a ring fixedly connected to the housing and engaged by the locking members in both rotating directions, a drive member coaxially arranged to the spindle with unlocking members cooperating with locking members releasing when the driving member is engaged, thereby releasing the driven member from the ring. Drive member cams are spatially separated from unlocking members wherein they penetrate the locking member. Driven members have catch openings such that both drive and driven members also have torque-transmitting catch surfaces for a motor-driven action of the spindle so that the catch surfaces have a larger distance from one another in a neutral position of the drive member than between the unlocking members and the locking members.
