Impact wrench

An impact wrench, with an overall “T” shape and comprising an upper handle assembly, a lower working assembly and an intermediate connecting bar connected between the handle assembly and the working assembly, wherein:

• the handle assembly comprises a first body with two elongated gripping handles extending in opposite directions and transverse to a longitudinal direction of the impact wrench, a manual operating member and a battery seat for receiving an electric battery,
• the working assembly comprises a second body, a tool-holder shaft, supported in a rotatable manner around an axis of rotation and adapted to support a screwing bush, an electric motor that can be powered by the battery and operable by the manual operating member, a transmission and a percussion mechanism connected between the motor and the tool-holder shaft to impart a rotation and percussion pulses,
• the connecting bar comprises a third, tubular body, with a first end portion coupled with a first coupling seat of the first body, and a second end portion coupled with a second coupling seat of the second body,
• wherein:
• (A) the first end portion and the first coupling seat both have a non-circular or polygonal or rectangular or square cross section, orthogonal to the longitudinal direction, so as to create an anti-rotation shape coupling with the interposition of a first damping assembly forming a damping layer between the first end portion and the first coupling seat, and/or
• (B) the second end portion and the second coupling seat both have a non-circular or polygonal or rectangular or square cross section, orthogonal to the longitudinal direction, so as to create an anti-rotation shape coupling with the interposition of a second damping assembly forming a damping layer between the second end portion and the second coupling
