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.

Abstract: A display comprises a display unit, and an elevator support structure, wherein the elevator support structure comprises a base, a first connecting element, a second connecting element, and a middle hinge assembly. The first connecting element is pivotally connected to the display unit, wherein the first connecting element rotates relative to the display unit around a first axis. The second connecting element is connected to the base, wherein the second connecting element rotates relative to the base around a second axis. The middle hinge assembly is pivotally connected to the first connecting element and the second connecting element, wherein the first connecting element rotates relative to the middle hinge assembly around a third axis, the second connecting element rotates relative to the middle hinge assembly around a fourth axis. The first, second, third and fourth axes are perpendicular to the display area.

Abstract: An axle mechanism capable of adjusting an elevation includes a support member, a lower hinge device at the bottom of the support member, an upper hinge device at the top of the support member, and a dual link rod module for connecting the upper and lower hinge devices. If the support member adjusts its elevation and front and rear distance, the turning radius of the dual link rod module is used as a moving range of the support member, such that two sets of pulling plates at the top produce a pushing action and an opposite pulling action to synchronously rotate the shaft rings on both sides of the top and drive the two movable rods to rotate without changing the original angle of the two upper support stands.
