Abstract
The present disclosure provides a retractable and foldable table leg structure, including a frame and a supporting leg. The frame defines a receiving cavity. The supporting leg includes a first supporting rod, a second supporting rod, a third supporting rod and a fourth supporting rod. The third supporting rod is slidably connected with the first supporting rod. The fourth supporting rod is slidably connected with the second supporting rod. The first supporting rod and the second supporting rod are rotatably connected with the frame, respectively. The supporting leg is configured to rotate to be received within the receiving cavity, and is adjustable in height by sliding the third supporting rod and the fourth supporting rod.
