Conversely, by moving the movable cylinder forward, the pivot positions at both ends of both links approach, the angles change in the direction in which both links bend toward each other, and the pivot positions between both links protrude in the radial direction of the main shaft. By performing this operation in a hole of equal diameter previously formed in the ground, a hole is formed whose diameter is enlarged by the protrusion of the digging blade made up of both links, and the excavated soil is sucked out from the tip of the main shaft by a vacuum. Furthermore, by moving the main shaft in the axial direction with the excavation blade protruding, a hole whose diameter has been enlarged is formed by the length of the movement.
