<p>A universal torque power tool has a housing (1) having motor means (4), a driving mechanism (5, 6) operatively connected with the motor means and including a drive having an axis (A) and being engageable with a nut (10) to be turned, first and second transfer members (12, 13) to apply a reaction force substantially coaxial with the axis of the drive and spaced from one another in direction of the axis, the drive being formed to transfer an action force from the motor means (4) to a nut to be turned, the transfer members being formed to engage a stationary object and to transfer a reaction force to the stationary object, so that when the stationary object is engageable outside of the nut engagement the first transfer member transfers the reaction force to the stationary object, and when the stationary object is engageable inside the nut engagement the second transfer member transfers the reaction force to the stationary object.</p> |
