Link 1 is designed in the form of a crankshaft having skew journals with axes a-a and b-b. The axes of the turning kinematic pairs, connecting links 1, 4 and 5, and 1, 2 and 3, intersect, respectively, at points A and B. Upon rotation of link 1 about its fixed axis, links 3 and 4 oscillate about axes c and d. The mechanism is symmetrical with respect to axis z-z.
