The universal wrench has a handle and a wrench body with reciprocally displaceable jaws and part- gripping teeth. An abutment end portion of the handle has circularly arranged teeth that cooperate with teeth on a rack provided on one of the jaws. The rack is reciprocally guided in the other jaw. A spring is secured to the handle and to this other jaw. A latch pin presses against the lower circular surfaces of this other jaw to secure the handle in different pivoting positions.
