The invention discloses a combined universal pulley. The combined universal pulley consists of three parts, namely, an inner pulley part, an outer pulley part and a suspension part; a rope wheel I is arranged on a bearing I in a sleeving manner; the bearing I is arranged at shaft-shaped positioning parts of two hemispheric positioning blocks; a wire rope I winds in a wire slot of the rope wheel I; the inner pulley part is placed in a special positioning groove which consists of two outer pulley positioning blocks, and can slide three-dimensionally in the groove; a rope wheel II is arranged on a bearing II in a sleeving manner; the bearing I is arranged at shaft-shaped positioning parts of the two outer pulley positioning blocks; a wire rope II winds and slides in a wire slot of the rope wheel II; a pulley sleeve positioning screw is connected with a pulley sleeve and connected with annular grooves of the two outer pulley positioning blocks in a sleeving manner, so that the purpose that the position of a pulley is adjusted universally in a certain area is achieved; a connecting rod, a locking rod, a locking nut and a positioning pin sleeve are connected together by using a connecting shaft and mounted in an arc-shaped groove of the pulley sleeve, and then the connecting shaft is limited by a connecting nut; the connecting rod slides in the arc-shaped groove of the pulley sleeve. Therefore, a suspended heavy object is kept in a vertical state because of the action of the gravity.
