The invention discloses a supporting leg telescoping linkage mechanism which comprises a sliding track, a movable supporting leg, a supporting cylinder, a curve guiding track and a stroke amplifying mechanism, wherein the supporting cylinder comprises a cylinder tube and a piston rod; the movable supporting leg slides in the sliding track and is connected with the supporting cylinder; the curve guiding track is connected with the movable portion of the supporting cylinder; one end of the stroke amplifying mechanism is connected with the curve guiding track and generates relative motion in the curve guiding track; the other end of the stroke amplifying mechanism is connected and fixed with the sliding track; and one point in the middle portion of the stroke amplifying mechanism is chosen to be connected and fixed with the movable supporting leg. Driving force perpendicular to the cylinder is converted to driving force in the horizontal direction, so that a main driving mechanism in the horizontal direction of the movable supporting leg can be replaced, the system structure of the whole mechanism is simplified, the driving mechanism which drives the movable supporting leg to stretch and retract horizontally is omitted, and the manufacturing cost of the mechanism is reduced.
