Circulating object power unit

The invention discloses a circulating object power unit, which is characterized in that a connecting rod is firmly connected with two movable pulleys which are the same but opposite to each other, a storage unit and a balance chamber are firmly connected to two sides of the connecting rod and symmetrical to the connecting rod, a counterweight is connected in the balance chamber firmly, a cable is connected with a heavy bob after winding around the movable pulleys, the cable wound around a group of fixed pulleys is firmly connected with a cable led from an axle, and the cable led from the axle is connected with a guide container. A weight is an object moving in the storage unit and the guide container circularly. When the two movable pulleys are lifted and stop rotating under action of the heavy bob, a resistance object is moved out of the storage unit and enters the guide container, the guide container containing the resistance object drives the heavy bob to return to the initial position by amplifying functi
