Abstract

FIELD: mechanical engineering. SUBSTANCE: screw-driver has housing provided with grooves, spring-loaded rod mounted inside the housing, and working tip coupled with the rod. The housing is made up as a mushroom and has a massive head. The rod with two pins is spring-loaded from one side to the housing and from the other side to the working tip. One of the pins interacts with the longitudinal guides on the housing. The other pin interacts with the inclined grooves on the working pin. The surface of the housing is provided with cylindric bushing that overlaps the guide grooves. EFFECT: enhanced safety. 2 cl, 1 dwg
