Flexible link 1 runs over pulleys 2 and 7, of equal diameter, and oscillates about fixed axis A. Link 3, designed as a complex lever, is connected by turning pairs D and C to pulleys 2 and 7 and by turning pairs E and H to links 6 and 4. Link 5 is connected by turning pairs F and G to link 6 and to link 4, designed as a bent lever which turns about fixed axis B. When flexible link 1 turns about axis A, links 3, 5 and 6 have complex motions and link 4 oscillates about axis B.
