The vertical rod is sleeved with a height adjustment ring which can move up and down along the vertical rod. The height adjustment ring is fixedly connected with an inner ring of a bearing. A connecting block is fixedly arranged on the outer wall of an outer ring of the bearing. The connecting block is connected with a telescopic rod in a hinged mode. The telescopic rod is perpendicular to the vertical rod. The telescopic rod is sleeved with a line scribing pen which can move leftwards and rightwards along the telescopic rod. Firstly, a circular-truncated-cone-shaped carrier platform is placed at a hole of a cover plate, the circular-truncated-cone-shaped carrier platform is located at the hole of the cover plate and does not fall, and the outer wall of the circular-truncated-cone-shaped carrier platform is tightly attached to the wall of a well. The vertical rod is inserted in an insertion hole of the vertical rod, and the insertion hole of the vertical rod is coaxial with the circular-truncated-cone-shaped carrier platform. In this way, the center of the insertion hole of the vertical rod is the circle center of a shaft. The height of the pen point of the line scribing pen is adjusted by adjusting the height adjustment ring according to the construction condition. The length of the telescopic rod is adjusted according to the construction condition, and a circle is drawn by means of the line scribing pen. The construction range can be cut and reinforced by constructors according to a drawn range.
