When the threaded sleeve moves downward, it drives the drilling machine to move downward to drill holes in the steel pipe. This makes it possible for the hole-opening equipment to position the steel pipe without the need for multiple driving components to cooperate and clamp, thereby reducing the production and use costs and the failure rate.
