Link 1 rotates about fixed axis x-x and is connected by a screw pair to link 2 which slides along fixed guide p. Lever 3 turns about fixed axis A and has pin a which enters groove b of link 1. The displacement of link 2 is the sum of its displacement due to the rotation of screw 1 about axis x-x and its displacement due to the axial traverse of link 1 along the same axis when lever 3 is turned.
