• a manually actuable clamping device including two stops arranged coaxially around said hollow spindle and including at least one elastic element for forcing said two stops into opposite directions, a first one of said stops being axially fixed and a second one of said stops being axially displaceable by means of said elastic element, said clamping device further including a clamping lever being operably connected to said axially displaceable stop for shifting said axially displaceable stop between a first axial retaining position for retaining said tool and a second axial releasing position for releasing said tool;
• a retaining element provided on said second end of said clamping bolt, said retaining element being impinged by said axially displaceable stop for retaining said tool non-rotatably when said axially displaceable stop is in said first retaining position and said retaining element being released when said axially displaceable stop is in said second releasing position.
