ABSTRACT

An impact wrench (1) with an upper handle assembly (2), a lower working
assembly (3) and an intermediate connecting bar (4) connected between the
handle assembly (2) and the working assembly (3) and comprising a tubular body
(4') with a first end portion (15) coupled with a first coupling seat (16)
of the handle assembly (2) and a second end portion (17) coupled with a second
coupling seat (18) of the working assembly (3), wherein the first end portion
(15) and the first coupling seat (16) both have a non-circular or polygonal or
rectangular or square cross-section, orthogonal to the longitudinal direction
(14), , so as to make an anti-rotation shape coupling with the interposition
of a first damping assembly (24) forming a damping layer between the first end
portion (15) and the first coupling seat (16).
