Abstract (en)
[origin: EP2248634A1] A torque-setting device includes a handle (10) with grooves (18) defined in an internal side, a driving unit (11) attached to the handle (10), a strain gauge connected to the driving unit, a strain spring (20) abutted against the strain gauge, a nut (33) abutted against the strain spring (20), an axle (30) and a knob (40). The axle (30) includes a thread. The thread is engaged with the nut (33). The knob (40) includes a tooth (42) on an external side. The knob (40) is operable to rotate the axle (30) relative to the nut (33), thus moving the nut (33) relative to the strain spring (20) to set a value of torque. The knob (40) is movable between a first position where the tooth (42) is inserted in one of the grooves to retain the value of torque and a second position where the tooth (42) is removed from the grooves to allow the rotation of the knob (40) and therefore the rotation of the axle.
