The utility model discloses a strain clamp angle regulator installed on a strain clamp. The strain clamp comprises a crimping tube, a drainage plate and a steel anchor. The angle regulator comprises an angle regulating plate and a limit rod. The steel anchor comprises a pull ring and an anchor rod. The head end of the anchor rod penetrates into the tail portion of the crimping tube and the tail end of the anchor rod is connected with the pull ring. The pull ring is nested in the angle regulating plate and the upper portion of the angle regulating plate is provided with a through hole fitting the pull ring. The pull ring is disposed in the through hole and the angle regulating plate is fixed. The angle regulating plate is provided with a plurality of round holes having different angles relative to the axis of the crimping tube. The limit rod is matched with any round hole and the drainage plate and the limit rod fixes the drainage plate relative to the angle of the angle regulating plate. The strain clamp angle regulator has the advantages that the angle of the drainage plate is regulated correspondingly based on the well-regulated limit rod on the angle regulating plate and then the drainage plate is fixed to the crimping tube, so that the angle of inclination and design and acceptance standard requirements for required drainage plates in engineering construction of different lines are met.
