FIELD: engineering of means for holding a length of rope, possible use in various industrial branches, where it is required to use a length of rope, held with stopping effect, for example, for locking objects, requiring usage of flexible link in form of length of rope. ^ SUBSTANCE: device is provided with screw and nut, meant for providing additional force effect on one of the rollers, which is positioned on a groove, abutting end surface of which is positioned closer to input aperture of longitudinal through channel. Screw is preliminarily made in form of longitudinal body of cylindrical shape, a portion of side surface of which on the side on one of its ends is threaded, and its diameter is greater than diameter of remaining smooth cylinder-shaped surface of screw. A portion of screw with threaded surface is positioned in the groove. ^ EFFECT: increased reliability. ^ 3 cl, 4 dwg |
