The invention is then placed in the shaft of the wireline well 1 such that the guide ring 12 with roller a16 is located just above the wellhead of the wireline well 1 and roller B45 is located at the inner corner of the wireline well 1. And then reversely rotating the two thread sleeves 7 in the two telescopic rod structures 4 to extend the two telescopic rod structures 4. When the two telescopic rod structures 4 drive the four arc plates 11 to meet the well wall through the two rods A3 and the four support legs 10, the threaded sleeve 7 is continuously rotated, so that the four arc plates 11 are tightly pressed against the well wall to fix the cable well 1 in the vertical shaft.
