PROBLEM TO BE SOLVED: To provide a recoverable-reusable removing anchor having an opening-closing blade operation mechanism. SOLUTION: This removing anchor has a case 1, a blade passing part formed in the case for penetrating an expansively opening blade, at least one blade head 5 slidingly arranged in the case, at least one expansively opening blade 6 expansively openably arranged on the blade head 5, and at least one expansively opening blade guide 2 arranged in the case for expansively opening the expansively opening blade outside the case by penetrating through the blade passing part. The removing anchor is constituted so that the blade head moves in the case; the expansively opening blade expansively opens outside the case by penetrating through the blade passing part while being guided by the expansively opening blade guide; and when the blade head returns to a storage position in the case, the expansively opening blade is stored in the case.
