1. A hinge structure, adapted to connect two parts, wherein the two parts are adapted to rotate relative to each other through the hinge structure, the hinge structure comprising:

  • a fixing member, adapted to be fixed at one of the two parts;

    a rotating member, pivotally disposed on the fixing member; and

    an extension member, pivotally disposed on the rotating member, and adapted to be fixed at another one of the two parts, wherein after the rotating member rotates relative to the fixing member along a rotating axial direction and the extension member rotates relative to the rotating member along the rotating axial direction, an included angle between the extension member and the fixing member presents an acute angle, so that the two parts are adapted to stand on a platform, and the extension member and the fixing member are adapted to increase the included angle therebetween through an external force exerted towards the platform, until the included angle presents 180 degrees and the two parts construct a plane;

    the fixing member has a first guide slot;

    the rotating member has a second guide slot and a first guide protrusion for sliding in the first guide slot during rotation of the rotating member relative to the fixing member; and

    the extension member has a second guide protrusion for sliding in the second guide slot during rotation of the extension member relative to the rotating member;

    the fixing member has a first connection portion, the rotating member is pivotally disposed in the first connection portion, the rotating member has a second connection portion, and the extension member is pivotally disposed in the second connection portion, and the first connection portion, the second connection portion and the extension member are overlapped to each other;

    a clamping member, clamping the first connection portion, the second connection portion and the extension member from outside inward, such that the fixing member, the rotating member and the extension member maintain fixed distances along a force-exerting axial direction of the clamping member;

    wherein the force-exerting axial direction is parallel to the rotating axial direction, such that the fixing member, the rotating member and the extension member clamped by the clamping member produce frictions therebetween when rotating relative to each other.
