Abstract
The invention is directed to a handheld or immersion blender including a coupling device (1) for separating the shank provided with a processing tool from the electrically powered drive part, with an upper coupling part (2) arranged on the drive part having locking elements and a lower coupling part (3) arranged on the tool shank having detent elements, which enable the coupling device (1) to be interlocked axially. In this arrangement the locking elements are formed by spring-loaded holding lugs (11) projecting radially outwardly, and the detent elements are formed by recesses (16) on the inner circumference of the lower coupling part (3), with the upper coupling part (2) being twistable relative to the lower coupling part (3), 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,…
