After immobilizing E in a plane, engage the lower ends of the engagement edges 4a of the resistance plate 4 from above each of the engagement tracks 3 fixed to the fixing member 1, and use an appropriate hitting tool such as a hammer. Then, the upper end of the resistance plate 4 is struck to make it slide downward along the engagement track 3. However, when the resistance plate 4 is struck, the fixed member 1 may sway due to the striking impact, or the Due to the shaking, the impact of hitting is caused by the resistance plate 4.
The situation that hinders the effective transmission of information is that the fixing member 1 is surrounded by earth and sand.
This is prevented by being immobilized by d′.
