A shoe capable of adjusting heel height, comprising:
- a front bracket;
- a rear bracket rotatably connected to the front bracket, and formed with a recess;
- a telescopic linkage rack pivotally connected to the rear bracket, and configured to be telescoped with the movement of the rear bracket, the telescopic linkage rack comprising a plurality of first shaft pins and a plurality of second shaft pins;
- a plurality of first connecting rods that are parallel one another;
- and a plurality of second connecting rods that are parallel one another, wherein each of the plurality of first connecting rods and each of the plurality of second connecting rods which are adjacent with each other are crossed to be pivotally connected to each other through one of the plurality of first shaft pins, and the plurality of first connecting rods and the plurality of second connecting rods are further pivotally connected to one another with an end-to-end manner through the plurality of second shaft pins, wherein, when the plurality of first connecting rods and the plurality of second connecting rods are rotated to gradually alter gaps between the plurality of first shaft pins from each other, the length of the telescopic linkage rack is correspondingly changed, and one of the first connecting rods is symmetrically pivotally connected to the rear bracket through the first shaft pin and the second shaft pin;
- an extendable support member fixedly connected to the telescopic linkage rack, and configured to be simultaneously telescoped in the same direction and in the same proportion with the telescoping degree of the telescopic linkage rack, wherein the extendable support member comprises a plurality of sleeves arranged concentrically and telescopically sleeved one another in sequence, and the telescopic linkage rack is received in the sleeves;
- a linking member pivotally connected to the front bracket and the extendable support member, and arranged spaced to the rear bracket, wherein the linking member is formed with a break, and the extendable support member is received within the recess and the break;
- and
- a locking mechanism configured to removably fix the extendable support member for limiting the telescoping of the extendable support member,
- one end of the front bracket is provided with a protruding rib, the rear bracket is pivotally connected to the one end of the front bracket through at least one first pivot, and pivotally connected to the telescopic linkage rack through at least two second pivots, the linking member is pivotally connected to the protruding rib through at least one third pivot, and pivotally connected to the extendable support member through at least one fourth pivot,
- wherein a four-bar linkage assembly is collectively defined by the protruding rib of the front bracket, the rear bracket, the telescopic linkage rack, the extendable support member and the linking member, and the at least one first pivot, the at least two second pivots, the at least one third pivot and the at least one fourth pivot are parallel one another,
- wherein when the rear bracket is rotated towards the front bracket, the four-bar linkage assembly collectively elongates the telescopic linkage rack in a gravity direction.
