SPRING MECHANISM FOR POWER DEVICE

摘要

A spring mechanism for attaching to a power device drive unit includes a housing connectable to a portion of the power device and a shaft extending through the housing. One end of the shaft is coupled to a workpiece and a bottom member extends from the other end and is positioned adjacent the drive unit. The bottom member includes at least one of a ferromagnetic material and a permanent magnet. The bottom member, shaft and workpiece move upon actuation of the drive unit, and a spring extends laterally outwardly from the shaft between the shaft and the housing. The spring is affixed to one of the shaft and the housing, wherein the spring bends between a deformed position and a return position upon the movement of the bottom member.
