Conductive metal pulley for pulling and releasing wire

The utility model discloses a conductive metal pulley for pulling and releasing a lead, which belongs to the technical field of pulling and releasing a lead rope and comprises an outer frame, a conductive shaft is rotatably mounted in the outer frame, a conductive pulley is fixedly mounted on the conductive shaft, a lifting groove is arranged on the inner side of the outer frame, three fixed guide rods are fixedly mounted on the outer frame, and the fixed guide rods are fixedly mounted on the lifting groove. And a threaded column is rotationally mounted on the conductive pulley. The utility model has the advantages that when a secondary traction wire needs to be added, the conductive pulleys on the outer frame are placed on the sequential traction rope, the threaded column is rotated at the moment, the annular limiting plate on the threaded column moves through the rotation of the threaded column, and the annular limiting plate ascends and descends in the lifting groove; the position of the annular limiting p
