Abstract:
A coupling device for separating a shank of a processing tool from an electrically powered drive part of a handheld blender, said coupling device comprising:an upper coupling part which during use is arranged on the drive part, said upper coupling part having a locking element; and a lower coupling part which during use is arranged on the tool shank, said lower coupling part having a detent element which enables the upper and lower parts to be interlocked axially, wherein the locking element is formed by a spring-loaded holding lug projecting radially outwardly, and the detent element is formed by a recess on an inner circumference of the lower coupling part, and the upper coupling part is twistable relative to the lower coupling part whereby a releasable coupling is obtained; wherein each of the upper coupling and the lower coupling part includes a separating device moving that coupling part axially away from the other coupling part when the upper and lower coupling parts are twisted.
