Lever 1, rotating about fixed axis A, is rigidly attached to pinion a which meshes with link 2. Link 2 turns about fixed axis B and is designed as a quadrant with gear segment b. Connecting rod 4 is connected by turning pairs C and D to link 2 and to press slide 3 which moves along fixed guides c-c. When lever 1 is rotated, first in one direction and then in the other, slide 3 is reciprocated through intermediate links 2 and 4.
