Bent lever 3 turns about fixed axis C. Cylinder 1 is connected by turning pair B to lever 3. Rod 4 of the piston sliding in the cylinder is connected by turning pair A to link 2. Link 2, connected by turning pair D to lever 3, has pin a which slides along circular slot b. When piston 4 moves into cylinder 1, the distance between axes A and B is reduced, and links 2 and 3 take the positions shown by dash lines. In the working position of the brace, points C, D and K are on a straight line.
