摘要： A torque-setting device includes a shank, a handle provided on the shank, a driving unit attached to the shank, a strain gauge connected to the driving unit, a spring abutted against the strain gauge, a pusher abutted against the spring, an axle engaged with the pusher, a restraining element connected to the axle, a C-clip provided on the restraining element, and a knob. The knob is operable to rotate the axle relative to the pusher, thus moving the pusher relative to the spring to set a value of torque. The knob is movable between a position where teeth thereof are in grooves of the handle to avoid rotation of the axle and another position where the tooth are out of the grooves to allow rotation of the knob and the axle. The C-clip is located against an annular rib formed on an internal face of the knob.

摘要： A torque-setting device includes a handle with grooves defined in an internal side, a driving unit attached to the handle, a strain gauge connected to the driving unit, a strain spring abutted against the strain gauge, a nut abutted against the strain spring, an axle and a knob. The axle includes a thread. The thread is engaged with the nut. The knob includes a tooth on an external side. The knob is operable to rotate the axle relative to the nut, thus moving the nut relative to the strain spring to set a value of torque. The knob is movable between a first position where the tooth is inserted in one of the grooves to retain the value of torque and a second position where the tooth is removed from the grooves to allow the rotation of the knob and therefore the rotation of the axle.
