Abstract (en)

[origin: EP0485661A1] 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 10 having, rotatably fixed thereon, a coupling element 14 with the rotation axis parallel but not co-linear with that of the main body 10. The main body 10 with one end thereof connecting to the motor spindle is engageable with a follower shaft 40 by means of the coupling element 14 to transmit torque to a socket engaging with the follower shaft 40. An arrestor 30 is provided to control the coupling element 14 so that when the rotation speed of the main body 10 exceeds a pre-specified value determined by the arrestor 30, the engagement between the main body 10 and the follower shaft 40 is enabled. <IMAGE>
