[0003] At present, multi-stage perforating guns on the market all need to be connected by wires along the pipe string from the beginning to the end. At the joint of the perforating gun, the wires of the two perforating guns need to be connected, or connected two by two through pins. In actual use, when the two ends of the multi-stage perforating gun are conducting electricity, the multi-stage perforating guns are mostly connected through the pins in the bidirectional wire passer, which makes it impossible for the bidirectional wire passer to independently connect the two ends of the multi-stage perforating gun in one direction. As a result, the two ends of the multi-stage perforating gun still need to be connected by wires when they are connected in one direction, which makes it inconvenient to install the two ends of the perforating gun, troublesome to wire, and there is a probability that the rotating two ends between the perforating guns will cause the problem of twisted wires.
