A handle is rotatably secured to the axle at a pivot pole for allowing the handle to rotate relative to the base about the axle and to rotate relative to the axle about the pivot pole. A rod is further rotatably secured to the base. The handle may be selectively secured to the axle or the rod for changing the rotational movement of the handle relative to the seat.
