Abstract (en)
[origin: EP2140977A1] The wrench has an anvil (36), and a hammer including a control part (20) for carrying a set of impact cheeks (24) and for rotation with a drive shaft (10) during non-impact. The control part performs an axial and additional rotational oscillation relative to the shaft during impact. The control part transmits rotation of the shaft to a rotating mass (22) of the hammer. The control part is movably guided in an axial direction in the mass for realizing an impact function, where the mass does not make an axial movement. The cheeks do not project beyond the mass in the direction.
