Abstract

Die Erfindung bezieht sich auf eine Schnellspannmutter (3) zum Festspannen von Trennscheiben (2) und anderen Werkzeugen auf einer Antriebsspindel (1) einer Antriebsmaschine, mit einer Gewindeaufnahmeöffnung für die Antriebsspindel (1) und einem von der Aufnahmeöffnung als weiteres Bauteil getrennt ausgebildeten Haltekörper (14), der in der Fixierstellung auf das Werkzeug (2) wirkend ausgebildet ist und den Haltekörper (14), der in der Fixierstellung zumindest mittelbar auf eine Anlagefläche der Schnellspannmutter (3) pressend ausgebildet ist, die mit der Aufnahmeöffnung in Verbindung steht, wobei die Anlagefläche von ihrer Arbeitsposition in eine Ruheposition verbringbar ist, in der der Pressdruck des Haltekörpers (14) auf die Anlagefläche zumindest reduziert ist.
