Abstract: An impact mechanism (12) for an impact wrench comprises an anvil (8) with a middle portion (13), at least one abutment surface (14) radially protruding therefrom, which forms at least one abutment surface (15), a hammer (4) with an impact surface (16) suitable to give rotational pulses to the anvil (8) by the impact surface (16) hitting the abutment surface (15). The anvil (8) comprises a first connection area (17) connecting the abutment portion (14) to the middle portion (13) within the axial extension of the abutment surface (15) and the middle portion (13) and a reinforcement rib (18) axially arranged out of the abutment surfaces (15) that connects the abutment portion (14) to the middle portion (13) of the anvil (8), thereby forming a second connecting area.

Abstract: An impact motorized wrench includes a tool-holder shaft arranged on a front side of the wrench and pivoting around a rotation axis, a rotary motion producing motor unit arranged on a rear side of the wrench opposite the front side and an operating member to operate the motor unit, a drive unit with a percussion mechanism being arranged between the motor unit and the tool-holder shaft. The motor unit, the drive unit and the percussion mechanism together form a base body of the wrench and the wrench includes two gripping handles attached to the base body, both being of elongated shape and transversally spaced apart relative to their longitudinal extensions. The handles define a common gripping plane tangential to both handles, which plane extends transversally to the rotation axis. The operating member is associated to one of the two handles.
