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