Electrical hand tool with a rotatable clamping element for a tool
DE 3313704 A1
In the case of an electrical hand tool with a rotatable clamping element for a tool and a locking device, which prevents the rotational movement of the clamping element, for the tool change with a switching slide (14), it is proposed, with a view to simpler handling, without having constantly to actuate an interlock means during tool change, to make the switching slide (14) such that it can be snapped into its locked position and released again manually. <IMAGE>
