Abstract
A joint structure includes a joint hollow body having a first plate and a second plate arranged opposite to each other, and the second plate has a penetrating hole for defining an axial direction with respect to the penetrating hole, and an external side plate is extended in the defined axial direction from the external periphery of the first plate and connected to the external periphery of the second plate, so as to enhance the structural strength of the joint hollow body and prevent the joint hollow body from having concentrated stress or being cracked easily.
