Patent ID: 7122921

Claim:
A driving assembly for a small power appliance, comprising: a drive member having a distal end portion, providing in operation a motion to a driven member assembly; a driven member assembly, mechanically separate from the drive member except when connected by an interface member, the driven member assembly including a drive shaft with a workpiece at a distal end thereof, the drive shaft moving in response to the operation of the drive member; and a single, unitary interface registration member, having a plurality of interface portions, wherein the interface member mechanically connects the drive member and the driven member assembly but does not drive the driven member assembly, wherein a first interface portion has directly connected thereto in a pre-established fixed relationship the distal end portion of said drive member and wherein the separate driven member assembly is removably received in a fixed relationship by the interface member at a second interface portion thereof, so that a reliable, fixed alignment between the drive member and the driven member assembly results, wherein the drive member is an electromagnet and the driven member assembly includes a driven element having a permanent magnet secured thereto at a rear end thereof, wherein cooperative interaction between the electromagnet and the permanent magnet produces motion of the driven element and the workpiece.
