The pawl is designed as plunger 2 sliding in guide a which is rigidly attached to lever 1. Ratchet wheel 3 and lever 1 turn independently of each other about fixed axis A. When lever 1 is turned counterclockwise about axis A, plunger 2 turns ratchet wheel 3 in the same direction. Plunger (pawl) 2 is disengaged from ratchet wheel 3 by turning handle 4 about axis B toward lever 1.
