Abstract: A structure of supporting shaft rod includes a retaining member having a retaining sheet and a retaining shaft rod; and a mobile supporting member having two supporting racks. The retaining shaft rod is inserted through a mobile buckling sheet and a retaining buckling sheet of two latching units. Each mobile buckling sheet has a pair of mobile protruding bumps. Each retaining buckling sheet has a pair of retaining protruding bumps corresponding to the pair of mobile protruding bumps. A wearing-resistant ring is located between the mobile buckling sheet and the corresponding retaining buckling sheet. The retaining shaft rod is inserted through the wearing-resistant ring. An outer circumference of the wearing-resistant ring is located between interior surfaces of the pair of mobile protruding bumps of the mobile buckling sheet and the pair of retaining protruding bumps of the corresponding retaining buckling sheet and an exterior surface of the retaining shaft rod.
