Patent ID: 7856695

Claim:
A structure of supporting shaft rod comprising: a retaining member having a retaining sheet and a retaining shaft rod, the retaining sheet has a pair of sheet flanks protruding outwardly, the retaining shaft rod is inserted through the pair of sheet flanks, each of two ends of the retaining shaft rod are inserted through one of two resilient supporting units, a first end of each the two resilient supporting units is connected to the retaining member and a second end of each the two resilient supporting units is connected to a mobile supporting member; the mobile supporting member has two supporting racks, each of the two supporting racks has a lug protruding from a top end thereof and corresponding to one of the two resilient supporting units, the retaining shaft rod is inserted through each lug, each of two ends of the retaining shaft rod is respectively provided with one of two latching units, each of the two latching units has a mobile buckling sheet and a retaining buckling sheet, the mobile buckling sheet is located at an outer side of a corresponding lug of each of the two supporting racks, the retaining shaft rod is inserted through the mobile buckling sheet and the retaining buckling sheet of the each of the two latching units, each mobile buckling sheet has a pair of mobile protruding bumps protruding outwardly, each retaining buckling sheet has a pair of retaining protruding bumps protruding outwardly and corresponding to the pair of mobile protruding bumps of a corresponding mobile buckling sheet, each of the two ends of the retaining shaft rod is respectively provided with at least one resilient unit and then is connected to an end sealing member; wherein, when the mobile supporting member is rotated, the pair of mobile protruding bumps of one of the mobile buckling sheets passing across the pair of retaining protruding bumps of the retaining buckling sheet provided adjacently to the mobile buckling sheet, and a storing status of the mobile supporting member is released and an initial operation status is therefore formed, wherein a wearing-resistant ring is located between the mobile buckling sheet and the corresponding retaining buckling sheet of each of the two latching units, 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.
