Claims

[Scope of utility model registration request]

A driving rod, a propulsion plate attached to the tip of the driving rod, and an expansion resistance formed along the center portion of the flat blade plate with a curved protruding strip fitted on the circumferential surface of the driving rod. a support rod attached to the peripheral surface of the distal end of the curved protruding strip of the expansion resistance plate; and a support rod formed to have approximately the same length as the support rod and attached to the base end of the wing plate of the expansion resistance plate. The expansion resistance plate consists of a connecting plate installed at the base end of the opening of the curved protruding strip, and an expansion indicator rod installed in the middle of the opening, which breaks under the load when the expansion resistance plate is bent. The distal end edge of the expansion resistance plate is attached to the driving rod circumferential surface via a rupture plate that is broken by the load of the expansion resistance plate. The supporting rod and the expansion indicator rod have wire binding rings formed at their respective free ends, and a space is provided on the circumferential surface of the curved protruding strip for escape of stress when the expansion resistance plate is bent. Horizontally elongated bent holes holding the curved protruding strips are formed at predetermined intervals in the axial direction of the curved protruding strips, and the distal end edge of the expansion resistance plate is arranged in a direction opposite to the protruding direction of the curved protruding strips. A stay anchor characterized by being directed.
