Impact tool for generating rotational impact force, has anvil with buffer mechanism performing buffer function in rotational direction and in axial direction to directly transmit rotational torque greater than set value

摘要

The tool has a motor, and a spindle that is rotated and driven by the motor. A rotational impact mechanism is attached to the spindle, where the impact mechanism generates a rotational impact force which is intermittently transmitted from a hammer (8) via an anvil (3) to a bit tool. An anvil comprises a buffer mechanism performing a buffer function in a rotational direction and in an axial direction to directly transmit a rotational torque greater than a set value.
