The invention has the following beneficial effects:

1. the invention has stronger convenience, safety and flexibility, and can safely and flexibly trim grasslands, landscape shrubs and high leaves.

2. The invention utilizes the pressure difference generated by air extraction and the thrust of wind to bend the close grass, shrub or leaf part into the mowing cavity and cut off by the mowing blade in the mowing cavity, thereby realizing the trimming of the grass, the shrub or the leaf.

3. The air draft device is of a backpack type, so that a user can operate the trimming device conveniently, and the strength requirement of the user is reduced.

4. The main body of the invention is a hollow rod body, has stronger operability, and is provided with the abutting part which can abut against the abdomen or the legs, thereby saving labor when lifting the hollow rod body.

5. The bending part is arranged, so that the operation habit and the human mechanics of a human body are met, and an operator can operate the electric tool more labor-saving and more natural.

6. The invention is provided with the inclined filter screen and the slag outlet, and scraps generated by cutting are intercepted at the filter screen and fall towards the slag outlet under the action of downward component force.

7. The hollow rod body between the slag hole and the abutting part is divided into two sections, and the two sections are rotatably connected through a rotating connecting sleeve, so that the slag hole can be ensured to face downwards by rotating the rod body part at the slag hole when the hollow rod body is rotated to trim high leaves.

8. The first filter pore plate and the second filter pore plate have a tiny distance; and the meshes on the two filter pore plates are staggered with each other, so that the holes on the two filter pore plates are respectively opposite to the plate surface, therefore, the fragments generated by cutting are not easy to be attracted by wind power to block the holes on the filter pore plates, and the fragments are convenient to slide off.

9. The upper side and the lower side of the opening in the length direction are provided with the cambered surfaces, and the cambered surfaces extend into the mowing cavity from the outer side surface of the front end of the mowing cavity, so that the blade can be effectively hidden, the safety is improved, and the leaf grass can be conveniently bent to enter the mowing cavity to be cut.

10. The invention has simple integral structure, can effectively realize the pruning operation, can effectively improve the operation distance by setting the hollow rod body as the telescopic sleeve rod, can reduce the volume at ordinary times and is convenient to carry and place.

11. The wind speed at the opening of the invention is larger, so the attraction of the invention is enough to bend the grass into the cutting groove cavity for cutting.
