A dual axle linkage mechanism on a door and casement window includes a plurality of rotary axle units, a supporting device and a driving device. The rotary axle units are disposed on a corner of the door and window. Each rotary unit has a spindle, an upper guiding block, a lower guiding block, a holding device, a retaining device and a restoring spring. Each supporting device has a frame and a guiding channel. Each driving device has a sliding block, a sliding blade and a spring strip. The driving device can move a pair of spindles on one side up or down in the frame, such that either side which has a spindle disposed therein can serve as a rotary axle of the door and window.
