[0027] When in use, the auger rod is installed inside the rotating column 206, and then a downward pressure is applied to the top plate 301 by a machine to push the top plate 301 to move downward. When the top plate 301 moves downward, it will give the auger rod a downward thrust, and at the same time it will drive the gear rod 302 to move downward.
