Abstract
An offset coupling includes a first coupling disc, a second coupling disc, and a multi-link structure. The first coupling disc includes a first pivoting portion, a second pivoting portion, and a third pivoting portion surround a first central axis. The second coupling disc includes a fourth pivoting portion, a fifth pivoting portion, and a sixth pivoting portion surround a second central axis. The multi-link structure includes a first linkage group, a second linkage group, and a third linkage group, two first cranks of the first linkage group are respectively pivotally connected to the first pivoting portion and the fourth pivoting portion, two second cranks of the second linkage group are respectively pivotally connected to the second pivoting portion and the fifth pivoting portion, and two third cranks of the third linkage group are respectively pivotally connected to the third pivoting portion and the sixth pivoting portion.
