The utility model discloses a connecting structure for connecting a blood pump and a cable conduit and ventricular auxiliary equipment, and the connecting structure comprises a tail cover and a compression ring. The tail cover is matched with a shell of the blood pump, a butt joint boss is formed at the end, away from the shell, of the tail cover, and the end of the butt joint boss is arranged to be suitable for being arranged on a cable guide pipe in a penetrating mode. The pressing ring is configured to be suitable for being arranged at the end, used for being in butt joint with the tail cover, of the cable conduit in a sleeving mode and used for pressing the cable conduit to the butt joint boss. When the cable conduit tends to loosen or rotate relative to the tail cover, the cable conduit is subjected to friction resistance of the butt-joint boss and the tail cover at the same time so as to limit continuous movement of the cable conduit. Therefore, the connecting strength between the tail cover and the cab
