The invention provides a stretching joint of a truss structure, which has excellent assembling operability and can bear high load. The joint structure of the invention is obtained through connecting rod-shaped components on which an extending load is applied through connecting components. The joint structure is characterized in that: the rod-shaped components which are interconnected respectively have a step; each step has a snapping surface which is snapped with the connecting component; each connecting component has a snapping surface which contacts with the snapping surface of the step; through the snapping surfaces of the connecting components, the steps of the rod-shaped components which are interconnected are clamped for snapping with the step; and furthermore on condition that the stretching load is applied, the rod-shaped components comprising the step are separated from one another. |
