Abstract

A wrench comprising a housing inside which a reversible electric motor serving as a torque source and a torque transmitting mechanism connected thereto are disposed. The torque transmitting mechanism comprises a rotatable cylindrical main body having, rotatably fixed thereon, a coupling element with the rotation axis parallel but not co-linear with that of the main body. The main body with one end thereof connecting to the motor spindle is engageable with a follower shaft by means of the coupling element to transmit torque to a socket engaging with the follower shaft. An arrestor is provided to control the coupling element so that when the rotation speed of the main body exceeds a pre-specified value determined by the arrestor, the engagement between the main body and the follower shaft is enabled.
