FIELD: optical instrumentation, sights. SUBSTANCE: mechanism includes lead screw with nut-pusher of elements of sight that establishes position of line of sight arranged in mount, flywheel, scale of angles of sight, base of sight with cylindrical guide put on body, bushing fixed on base with the use of flange that can turn. Lower part of mount of lead screw is conjugate to cylindrical bushing. Flywheel is made fast to bushing and upper part of mount of lead screw is located inside bushing to form screw pair and is fixed against turn in cylindrical bushing with key put in grooves cut in lower part of mount and cylindrical bushing of base. Scale of angles of sight is deposited on flywheel. Lead screw is provided with position lock. EFFECT: simplified process of adjustment, shortened adjustment time and enhanced functional reliability of mechanism. 5 cl, 1 dwg
