Patent ID: 7313974

Claim:
A dynamometer tool for manually applying torque to a fastener element, the dynamometer tool having a longitudinal axis and comprising: a drive portion at a distal end of the dynamometer tool; a handle portion at a proximal end of the dynamometer tool; an intermediate portion connecting said drive portion to said handle portion, said intermediate portion including a tubular element, said tubular element containing a mechanical calibration device; a support module totally within the dynamometer tool, said support module including (i) a body substantially cylindrical in shape and extending along the longitudinal axis, said body being delimited by two end faces, having a passageway extending along the longitudinal axis and being open at each of said two end faces for allowing an operator to insert an adjusting tool from the proximal end of the dynamometer tool and through said passageway in order to access said mechanical calibration device, and having at least one recess arranged around the longitudinal axis, and (ii) at least one electrical power supply member in said at least one recess; and an equilibrium-breaking mechanism for delivering a predetermined torsion torque to said drive portion, wherein said mechanical calibration device extends along the longitudinal axis and is for calibrating a biasing structure that cooperates with said equilibrium-breaking mechanism for setting the predetermined torsion torque.
