[0038] Here’s how it works:
[0039] First, adjust the length of the weeding device according to the user's height, rotate the threaded rod 111, so that the threaded tube 111 rotates on the fixed thread 101 on the extension rod 10, so that the tilting block 113 gradually presses down the end of the rotating block 122, so that the main rod 4 can be pushed into the internal cavity of the extension rod 10. When the length of the weeding device is appropriate, the threaded tube 111 can be rotated in the opposite direction. Under the pushing action of the limit spring 123, the rotating block 122 rotates, so that the locking block 124 fixedly connected to the rotating block 122 is locked into the corresponding locking hole 15, and the length adjustment of the weeding device is completed.
[0040] Then, the motor 2 is started, so that the cutting knife 31 fixedly connected to the output end of the motor 2 rotates, so that the weeds in the designated area can be cut and cleaned. At the same time, the anti-collision strip 14 at the front end of the weeding device can prevent the cutting knife 31 from hitting stones, causing damage to the blade of the cutting knife 31. The baffle 6 can prevent the weeds cleaned by the cutting knife 31 from being thrown to the staff behind. When a large area of weeds needs to be cleaned, the cutting chain 33 can be threadedly connected to the cutting knife, so as to expand the cutting area and facilitate the cleaning of a large area of weeds.
[0041] When cleaning work is performed on a flat area, the support frame 72 can be rotated so that the support rod 74 is engaged with the locking block 8, and then the nut 82 is threadedly connected to the first locking hole 81 to fix the support rod 74 on the locking block 8, so that the weeding device can be pushed to remove weeds.
[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
