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.

The chelate structure was examined by AFM scaning, single strand structure at AFM gram is Ala-Gln, two combined single strand is Ala-Gln-Zn~(2+), and atomic radius of Ala-Gln-Zn~(2+)'s conjunctive atom is about 0.24 to 0.25nm, which is near to Zn~(2+), so the conjunction atom is Zn~(2+). Thus the coordination reaction and the molar ratio 2:1 is proved again.
