Abstract
The system includes a plurality of joining assemblies (37, 38, 39) for removably attaching a driven member assembly (15) of the appliance to an appliance body portion (12), wherein the joining assemblies are separate from the torsional axis of the workpiece. The joining assemblies each include an extending pin member (43) on the appliance body and a receiving element (46) in the driven member assembly for receiving the extending pin member. A drive shaft (16) for the workpiece is connected to a head portion (24) of the driven member assembly by two springs (32, 34), wherein the extending pin member mates with the receiving element in such a manner that there is no lost motion of the workpiece during operation but also such that the driven member assembly is readily removable from the appliance body.
