ABSTRACT:
A manually operated impact tool is provided and includes: an impact mass; an anvil rotatably disposed relative to the impact mass; an input member operatively connected to one of the impact mass and anvil mass for imparting a relative rotation between the impact mass and the anvil; an output member connected to the other of the impact mass and anvil mass for transferring an impact to a fastener; and one or more elastic elements for storing potential energy upon the relative rotation between the impact mass and the anvil. Wherein conversion of the potential energy to kinetic energy causes the impact mass to impact the anvil and transfer of the impact to the output member.
