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.

A toothbrush includes a handle, a head and a movable portion affixed to the head. In one embodiment, the head includes an upper surface and a lower surface opposite said upper surface. A recess extends into the upper surface and includes a floor, and a pair of walls extending upwardly from the floor to the upper surface. A central support may be suspended above the floor by a pair of arms that extend from opposite ends of the central support and into notches in the opposing sidewalls of the recess. A portion of the arms may be affixed in the respective notches, and a portion of the arms may be spaced from the walls of the notches to enable the arms to twist within the notches, and this enable movement of the central support.

A replacement head for an electromagnetic toothbrush drive includes a mechanical linkage assembly for converting linear drive motion into rotational movement of the brush head. The mechanical linkage assembly includes a fixed shaft and a lever arm that extend between a movable bottom member and a fixed top member, and a link member rotatably connected to the top member and the brush head. The lever arm pivots about a fulcrum formed in the top member, and engages the link member. When the bottom member oscillates as a results of the actuation of the electromagnet in the drive unit, the lever arm pivots about the fulcrum and drives the link member to rotate in an arc shaped pattern. The rotation of the link member consequently rotates the brush head.
