An electric torque wrench capable of sensing a manual operating torque includes: an outer housing having an accommodating space at an internal thereof, a motor and a reduction device arranged therein; the reduction device having a reduction gear assembly with a hollow ring gear member; a front end of the ring gear member having at least one extension arm and at least one sensing plane formed thereon; a torque sensing unit arranged on the sensing plane; a driving device installed at the front end of the outer housing and having a working head arranged at the front end thereof; the extension arm of the ring gear member secured and attached onto the driving device. With the torque sensing unit installed on the extension arm, the electric torque wrench can be rotated manually with hand and is able to measure the torque value.

Electric torque wrench capable of sensing manual operating torque

A torsional strain sensing device comprises a cylindrical hub and a frame. The frame surrounds the cylindrical hub and includes a first sidewall, an opposite second sidewall, a first connecting wall extended between the first sidewall and the second wall at one end, and a second connecting wall extended between the first sidewall and the second sidewall at the opposite end. The first sidewall has a first flat lateral outer surface, and the second sidewall has a second flat lateral outer surface. The first and second lateral outer surfaces are adapted for attachment of strain sensors thereon. A first cavity and a second cavity oppositely defined between the cylindrical hub and the frame.
