ABSTRACT:
A rotary driver providing continuous uninterrupted rotation, which allows the user to install rotary fasteners without the tedious and potentially harmful long term effects of twisting the wrist. The tool comprises a handle of the size and shape to comfortably fit in a hand of a operator, connected to a tool shank which extends axially therefrom. The shank carries a tool tip at its distal end. The handle also incorporates a lever arm that extends outward from the longitudinal axis of the shank. A free spinning lever arm handle is mounted at its extended end creating a crank arm assembly for the rotary driver. This assembly is attached to the handle by a pivot at its end. The assembly can then be rotated from a stored position in a handle pocket to a extended working position. When the crank arm assembly is in the stored position, the rotary driver appears and functions like a traditional screwdriver.
