1. A hinge mechanism, suitable for a foldable electronic device, wherein the foldable electronic device has a first body, a second body and a hinging-body;

  • the hinge mechanism comprising;

    a first cradle, configured to be fixed to the first body;

    a second cradle, configured to be fixed to the second body;

    a pair of pivoting-shafts, respectively fixed to the first cradle and the second cradle;

    a pair of position-limiting elements;

    a set of gears, having a pair of primary gears and a pair of secondary gears, wherein the pair of primary gears is located between the pair of position-limiting elements, the pair of pivoting-shafts goes through the pair of position-limiting elements and respectively goes through the pair of primary gears to make the pair of primary gears pivoted between the pair of position-limiting elements, the pair of secondary gears is located between the pair of position-limiting elements and pivoted to the pair of position-limiting elements, the pair of primary gears is respectively engaged with the pair of secondary gears, and the pair of secondary gears is engaged with each other; and

    a positioning-element, configured to be fixed to the hinging-body and structurally independent from the pair of position-limiting elements, wherein the positioning-element is pivoted to the pair of pivoting-shafts so as to be detachably assembled with the pair of position-limiting elements, the first body rotates relatively to the hinging-body through the first cradle rotates the pivoting-shaft fixed to the first cradle relatively to the positioning element so as to bring both the pair of primary gears and the pair of secondary gears for rotation, to make the second cradle rotate the pivoting-shaft fixed to the second cradle relatively to the positioning-element and to bring the second body for rotation relatively to the hinging-body.
