ABSTRACT:
A locking device is disclosed to prevent a rotatably journalled part of a portable tool from rotating. The locking device includes a blocking element which coacts with the rotatably journalled part for blocking the rotation thereof. The blocking element is disposed on the tool and can be shifted from a clear position permitting rotation into a blocking position preventing rotation. In the latter position, the blocking element is braced against the tool. Thus, the blocking element is always present on the tool and is available for use at any time. The blocking element does not need to be held manually in the blocking position because it is supported on the tool.
