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