Slider 1 moves along fixed guides p-p whose axis coincides with axis Ax. Slider 1 is connected by a sliding pair to link 5 which, in turn, is connected by turning pair B to link 3 having the form of a bent lever with the angle nBm equal to 90°. Arm Bn of link 3 moves in slider 4 which is connected by turning pair D to slider 1. Arm Bm of link 3 moves in slider 2 which turns about fixed axis A. When slider 1 moves along guides p-p, point B describes parabola q-q with the equation y²=2px, where p is the distance from the focus of the parabola to its directrix.
