When the extension length of the cross rod 14 from the first sleeve 11 needs to be increased by using the telescopic regulation mechanism, because the second pull rope 49 is in a loose state initially, under the action of the third spring 43, most of the second spiral block 42 extends out of the second spiral groove 47, strong wind blows the first rotating blade 6, the arc-shaped plate 5 and parts above the first rotating blade to rotate, part of the bottom of the second spiral block 42 extends into the ground, the arc-shaped plate 5 rotates to drive the third sleeve 36 to rotate, in the process that the third sleeve 36 rotates on the ground, earth on the ground gives a reverse axial acting force to the second spiral block 42 and the third sleeve 36, under the acting force, the cross rod 14 continuously extends out of the first sleeve 11, the extension amount of the cross rod 14 from the first sleeve 11 is increased, the third sleeve 36 rotates to drive the rotating shaft 17 to rotate, the rotating shaft 17 rotates to drive the second rotating blade 18, and the second rotating blade 18 rotates, the grass on the ground can be pulled out by matching with the rectangular through hole 20 on the second sleeve 16, and the telescopic regulating mechanism can pull out the grass in a wider range; when the length of the cross rod 14 extending out of the first sleeve 11 needs to be shortened, the electromagnet 40 is started, the electromagnet 40 adsorbs the second movable block 38 until the first pull rope 48 is in a loose state, the second pull rope 49 is in a tightened state, most of the first spiral block 41 extends out of the first spiral groove 46, most of the second spiral block 42 extends into the second spiral groove 47, the bottom of part of the first spiral block 41 is inserted into the ground, the cross rod 14 is also provided with a reverse axial acting force in the rotating process of the third sleeve 36, and the acting force enables the cross rod 14 to continuously extend into the first sleeve 11.

Further, as shown in the drawings, a plurality of pulleys 50 are mounted on the outer wall of the circular tube 37 according to the embodiment, and the first pull rope 48 and the second pull rope 49 are wound around the corresponding pulleys 50. The pulley 50 can make the sliding of the first and second pulling ropes 48 and 49 smoother.

Furthermore, as shown in the drawings, a first gear ring 23 is installed at the bottom of the supporting plate 9 in the embodiment, the first gear ring 23 is formed by assembling two vertically symmetrical half gear rings, a first gear 24 is installed on the generator 22, the first gear 24 and the first gear ring 23 are engaged with each other, and the electric energy generated by the generator 22 is stored in a storage battery 26. The strong wind blows the first rotating blade 6 to rotate, the first rotating blade 6 rotates and drives the supporting plate 9 and the first gear ring 23 to rotate, the first gear ring 23 can drive the generator 22 to rotate through the first gear 24, and the electric energy generated by the generator 22 is stored in the storage battery 26.
