<p>A double-hinge structure comprising a coupling plate 1, a resistant hinge 2 and a cam hinge 3. The coupling plate 1 has a first retaining hole 11 and a second retaining hole 12 to retain respectively the resistant hinge and the cam hinge. The resistant hinge 2 has a fastening axle 22 at one end fastened to the coupling plate 1 and a movable sleeve 21 at another end. The cam hinge 3 has one end fastened to the coupling plate and a stem 31 running through an anchor plate 32, a first element 33, a second element 34 and a spring 35 to be fastened by a nut 36. The resistant hinge serves as an axis of a first stage swivelling to be flipped like a notebook computer use condition. The cam hinge 3 serves as another axis for a second stage swivelling to be flipped like a tablet computer in a back-to-back use condition. Thus users can selectively perform input operation in a handheld or desktop fashion.</p> |
