ABSTRACT:
An impact wrench that may be used in various industries for tightening threaded fasteners. In the impact wrench, a hammer and an anvil are coaxially mounted in a space relationship and axially movable with respect to each other. The impact wrench is provided with a device for effecting said relative axial movement of the hammer and anvil for engagement of their impact jaws, and a device for interaction of the hammer and anvil prior to the engagement of their impact jaws.
In the impact wrench, the hammer and anvil jaws are engaged over the entire height, whereby the wear of the jaws is considerably reduced, the energy of a single blow is increased, vibration as lowered and torque tightening is ensured.
