Flexible connector cast iron pipe

The utility model relates to the technical field of cast iron pipes, and discloses a flexible connector cast iron pipe which comprises a rubber corrugated pipe. According to the flexible connector cast iron pipe, the effects that the rubber corrugated pipe is easy to bend and the cast iron pipe is easy to connect are achieved, the fixing plate block and the two connecting mechanisms are fixedly arranged on the outer surface of the rubber corrugated pipe in a sleeving mode respectively, and the clamping plate clamps the steel wire rope by rotating the nut; the two steel wire ropes are fixedly arranged in the two fixing pieces correspondingly to be stable, a motor drives a rotating rod to rotate, so that a rotating wheel rotates, the two steel wire ropes move, the two steel wire ropes drive the fixing pieces to move, and the two connecting mechanisms drive the two sides of the rubber corrugated pipe to be bent towards the middle position; and through the hinged stop block, the pawl fixedly arranged in the sleev
