Having space, change 3 and blade 4 to be located in the space of fetch earth pipe 1 bottom and shoe 6 junction, on the one hand institute's spacing ensures
Blade 4 and change 3 are freely rotatable, on the other hand limit change 3 and move up and down；Shoe 6 is internally provided with cushion cap 63, on cushion cap 63
Uniformly laying 12 pin holes 62, arrange 1 keyway 31, inner side arranges 12 cotter slots 32 outside change 3, blade 4 includes leaf
Sheet body 41 and two pins 42 being perpendicular to blade body 41, two pins 42 lay respectively at blade body 41 two ends phase negative side
To layout, one of them pin 42 inserts the pin hole 62 on cushion cap 63, and another pin 42 snaps in the cotter slot inside change 3
32；The pipe 2 that narrows is assemblied in fetch earth pipe 1 and the outer wall of shoe 6, narrow pipe 2 can with fetch earth pipe 1 and shoe 6 the most freely rotatable,
Pipe 2 inwall that narrows is provided with key 22, and key 22 is by the keyway outside the spacing rectangular opening 61 being opened on shoe 6 wall and change 3
31 assembly connections, spacing rectangular opening 61 limits the rotational angle of change 3, thus controls the rotational angle of blade 4, narrows outside pipe 2
Wall is provided with agnail 23, and when rotating clockwise, agnail 23 resistance is less, and when rotating counterclockwise, agnail 23 is cut in soil, and resistance is relatively
Greatly, it is provided that limit the resistance that the pipe 2 that narrows rotates counterclockwise.
Blade 4 is in arc-shaped, and blade 4 internal diameter and pipe 1 internal diameter that fetches earth, shoe 6 internal diameter are identical, blade 4 external diameter and the pipe 1 that fetches earth
Identical with the diameter of thread of shoe 6 junction, blade 4 radian is less than 180 °, and blade 4 is relatively thin and has sufficient intensity, blade 4 number
For identical with the number of pin hole 62.
Change 3 internal-and external diameter is identical with blade 4 internal-and external diameter.
Shoe 6 bottom is coniform, and shoe 6 internal-and external diameter is consistent with pipe 1 internal-and external diameter that fetches earth.
Narrow pipe 2 internal diameter with fetch earth pipe 1 and shoe 6 external diameter identical.
Pipe 1 outer wall that fetches earth has the pipe clamp groove 11 that fetches earth, and shoe 6 outer wall has shoe draw-in groove 64, and narrow pipe 2 upper and lower side inwall
