Coupling device for an appliance for domestic use

Abstract

The invention is directed to a coupling device (1) for an appliance for domestic use, in particular a handheld blender, for connecting a drive part (7) to a tool shank (6), with a locking device (2) having locking elements (3) being arranged on a coupling section of the drive part (7), said locking elements being in engagement with depressions (10) formed on the inner circumference of the tool shank (6) in the locked state. The invention is characterized in that the locking device (2) is constructed as an annular spring element and that in the area of the locking element (3) provision is made for an actuating device (4) causing, when actuated, the spring element to be deformed elastically such that the locking element (3) moves inwardly, hence becoming disengaged from the detent element (10).
