Abstract
The invention is directed to a handheld or immersion blender including a coupling device ( ) for separating the shank provided with a processing tool from the electrically powered drive part, with an upper coupling part ( ) arranged on the drive part having locking elements and a lower coupling part ( ) arranged on the tool shank having detent elements, which enable the coupling device ( ) to be interlocked axially. In this arrangement the locking elements are formed by spring-loaded holding lugs ( ) projecting radially outwardly, and the detent elements are formed by recesses ( ) on the inner circumference of the lower coupling part ( ), with the upper coupling part ( ) being twistable relative to the lower coupling part ( ), whereby a releasable coupling is obtained. An improved handheld or immersion blender is thereby made available. The processes of coupling and decoupling an attachment to and from a drive part are made possible readily and without any major force using a simple click-in/turn-out motion. With the coupling of the handheld or immersion blender of the invention requiring only a small number of components and with no need to fit any additional actuating elements, blender operation is simple and manufacture straightforward.
