The upper ends of the poles with the openings are connected with the spiral springs attached onto the frame. The lower ends with attached duckfoot shovels are folded at the angle β=100-105° providing for the gouging angle within α=10-15°. The cutting edges of the shovels are sharpened at the angle of δ=20-30°.
