Abstract (en)
[origin: US4793226A] In a manual device for driving screws or similar fasteners, it is proposed that a known power activating mechanism which operates in accordance with the ram setting principle and which exerts an axial force upon a second ram which is disposed behind a first ram be provided, with the second ram, which meshes positively with and is guided in a guide barrel associated thereto, simultaneously performing axial and rotational motions, and that a screw be held on the front portion the second ram in such a manner as to permit it to be driven into an appropriate, mating material.
