Abstract

Die Erfindung betrifft ein Handwerkzeuggerät mit einer einen Werkzeugflansch für ein rotierend antreibbares flächenhaftes Werkzeug aufweisenden Antriebsspindel, mit einer auf das freie Ende der Antriebsspindel aufschraubbaren und das Werkzeug gegen den Werkzeugflansch drehfest klemmenden Spannmutter (2) und mit einer auf der dem Werkzeugflansch abgewandten Seite des Werkzeugs angeordneten und ein Betätigungselement (18) aufweisenden Entlasturigsvorrichtung (4), deren axiale Erstreckung (6) reduzierbar ist, um die Spannmutter (2) zu lösen, wobei die Entlastungsvorrichtung (4) ein erstes Funktionsteil (8) und ein zweites Funktionsteil (10) aufweist, zwischen denen ein eine keilartige Schrägfläche (36) aufweisender Klemmkörper (12) und ein Stellkörper (14) angeordnet ist, wobei der Stellkörper (14) den Klemmkörper (12) gegen eine Bewegung nach radial außen festlegt, so dass der Klemmkörper (12) das erste Funktionsteil (8) und das zweite Funktionsteil (10) in axialer Richtung stützt. Es zeichnet sich dadurch aus, dass der Stellkörper (14) einen unrunden Querschnitt aufweist, und dass er in einer ersten Funktionsstellung eine maximale radiale Erstreckung (20) aufweist und mittels des Betätigungselements (18) um eine Drehachse (24) in eine zweite Funktionsstellung drehbar ist, in der seine radiale Erstreckung (20) reduziert ist, so dass der Klemmkörper (12) nach radial außen bewegbar ist und so eine Reduzierung der axialen Erstreckung (6) der Entlastungsvorrichtung (4) erzielbar ist. (Figur 1)

The invention relates to a hand tool with a tool flange for a rotationally driven planar tool having drive spindle, with a screwed onto the free end of the drive spindle and the tool against the tool flange against rotation clamped clamping nut (2) and with a remote from the tool flange side of the tool arranged and an actuating element (18) having Entlasturigsvorrichtung (4) whose axial extent (6) is reducible to release the clamping nut (2), wherein the relief device (4) has a first functional part (8) and a second functional part (10) between which a clamping body (12) having a wedge-like oblique surface (36) and a setting body (14) is arranged, wherein the setting body (14) fixes the clamping body (12) radially outwardly, so that the clamping body (12 ) the first functional part (8) and the second functional part (10) in the axial direction supports. It is characterized in that the adjusting body (14) has a non-circular cross-section, and that it has a maximum radial extent (20) in a first functional position and is rotatable about an axis of rotation (24) into a second functional position by means of the actuating element (18) is, in which its radial extent (20) is reduced, so that the clamping body (12) is movable radially outward and so a reduction of the axial extent (6) of the relief device (4) can be achieved.
