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.
