ABSTRACT:
The manually-actuated, rotary-impact tool for rotatively driving a fastener has a spring in a handle for storage of energy, a rotatable tool head and an inertia member surrounding the tool head and connected to the handle via driving connections. A cam associated with the handle is provided to coact with the driving connections to disengage the driving connections when the tool head rotation is resisted by a predetermined force and the handle is rotated relative to the tool head and to allow re-engagement of the driving connections in another operative condition. A lever arm is pivotally connected to the handle so as to coact with the handle and inertia member to actuate the spring for storage of energy upon resistance of the tool head to rotation and to rotate the inertia member under the force of the stored energy of the spring and effect conversion of the kinetic energy of the inertia member to impact force on the tool head upon re-engagement of the driving connections. The pivotal connection of the lever arm is offset from the longitudinal axis of the handle.
