A link attachment to a torque wrench providing coaxial action in the reaction turning forces in opposite directions at equal torque, the link attachment has a housing, a ratchet mechanism including a ratchet engageable with a fastener and a drive plate turning the ratchet, a first connecting structure for connecting the housing to a part of the torque wrench providing a reaction turning force and a second connecting structure for connecting a part of the torque wrench providing an action turning force for the at least one lever drive plate, so that a turning action of the torque wrench is converted into a linear action applied to the at least lever drive plate so as to turn the at least one lever drive plate and thereby to turn a fastener by the ratchet, while abutting against a nearby stationary object with the housing to stop the torque wrench from turning around the fastener to be tightened or loosened.
