As shown in fig. 8, when the electronic device and the hinge 1 are in a 95 degree state, the outer contour 120 of the second shaft portion 12 abuts against the inner contour 420 of the second end portion 42 of the second torsion member 40 to maximize the inner contour 420, and the torsion of the hinge 1 is added to the fixed 2.8Kgf-cm provided by the first torsion member 30 and the torsion provided by the second torsion member 40, so that the torsion of the hinge 1 is maximized to 3.5 Kgf-cm.
As shown in fig. 8 and 9, when the electronic device and the hinge 1 gradually change from the 95 degree state to the 120 degree state, the outer contour 120 of the second shaft section 12 abuts against the inner contour 420 of the second end 42 of the second torsion member 40 to make the inner contour 420 continuously be the maximum, and the torsion of the hinge 1 is maintained at the maximum 3.5 Kgf-cm by the first torsion member 30 and the second torsion member 40.
