It comprises an in-put shaft hinged to its yoke through one axis, and an out-put shaft also hinged to its yoke through another axis, and these two yokes (13) were combined together by only one axis position, perpendicular to that two yoke axes like a cross, so that this combined axis will bend just like the angle bisector of that two shafts to maintain its constant velocity by a few methods, firstly, by using a section of gear teeth mesh at both ends of the shafts' teeth were so polished so that it can turn longitudinally as usual gear, and also sideways, to provide a larger solid angle of turning from ordinary 45 degrees into 60 or even more.
