Besides that, active part has mechanisms for drawing off the hooks at retracted position and mechanisms for releasing the latches at extended position, hook extended position retainer and handle connected with one of movable members of hook motion mechanism. Teeth of preliminary gripping latches are received by holes found in zone of engagement of sleeve and funnel. Latches and hooks are spring-loaded in direction towards axis of sleeve and hook motion mechanism is spring-loaded in direction of hook retraction. Hook ends are received by longitudinal slots of seat and have additional degree of freedom across direction of extension. Passive part of unit has shoulders with stops for hook ends which are located on head of pin and grooves with stops for latch teeth are available. EFFECT: extended functional capabilities; enhanced reliability. 7 cl, 10 dwg
