The rear end face of the limit block 16 is movably connected to the limit plate 17, and the rear end face of the limit plate 17 is in contact with the front end face of the annular plate 13. The end of the limit plate 17 away from the limit block 16 is slidably connected to a stop cover 18, and the stop cover 18 is located inside the mounting frame 9. The front end face of the stop cover 18 is provided with a limit slot 21, and the front end face of the limit plate 17 is fixedly connected to a connecting column 22, and the connecting column 22 is located inside the limit slot 21. The movable slot 11 is divided into two parts, the front part is rectangular to facilitate the entry of the limit plate 17, and the rear part is annular to cooperate with the installation of the annular plate 13. When the stop cover 18 is installed, the stop cover 18 is used to push the limit plate 17, so that the limit plate 17 moves down from the entrance of the movable groove 11, contacts the limit block 16 and pushes it, so that it rotates under the action of the fixed column 14 and the torsion spring 15 until the annular plate 13 is squeezed. When the limit plate 17 is separated from the limit block 16, the limit block 16 is reset under the reaction force of the torsion spring 15, and when the annular plate 13 moves down, the first spring 12 is compressed, so that the first spring 12 is pressed. A spring 12 generates a reaction force on the annular plate 13; after stopping pushing the blocking cover 18, the first spring 12 pushes the limit plate 17 through the annular plate 13, so that it fits with the rear end surface of the limit block 16, so that the limit plate 17 is limited by the limit block 16 to achieve the installation of the blocking cover 18; when disassembling, it is only necessary to pull the connecting column 22 from both sides to the middle at the same time to separate the limit plate 17 from the movable groove 11, and the blocking cover 18 can be removed for cleaning, making installation and disassembly convenient.

When the connecting post 22 drives the limit plate 17 to slide into the interior of the chute 19, the limit plate 17 compresses the second spring 20, causing the second spring 20 to generate a reaction force on the limit plate 17. The limiting groove 21 also limits the movement path of the connecting post 22, preventing the limit plate 17 from moving too short a distance, which would damage the second spring 20 and affect its elasticity, thereby extending the service life of the present invention.

A rotor 6 is mounted on the exterior of the rotor frame 5, and a propeller 23 is fixedly connected to the inner sidewall of the rotor frame 5. The rotor 6 cooperates with the stator 3, allowing the rotor frame 5 to drive the propeller 23 to rotate, thereby achieving the propulsion function.

[0028] Mounting bracket 9 is internally movably connected to a screw 10, with the end of screw 10, facing away from mounting bracket 9, threadedly connected to the inner wall of second mounting slot 8. Screw 10 secures mounting bracket 9 to housing 1. During use, the cover 18 of this utility model blocks weeds, and the lack of a rotating shaft further enhances the utility model's anti-entanglement properties.

When the limit plate 17 is separated from the limit block 16, the limit block 16 is reset under the reaction force of the torsion spring 15, and the annular plate 13 moves down to compress the first spring 12, so that The first spring 12 generates a reaction force on the annular plate 13; after stopping pushing the blocking cover 18, the first spring 12 pushes the limit plate 17 through the annular plate 13, so that it fits with the rear end surface of the limit block 16, so that the limit plate 17 is limited by the limit block 16 to achieve the installation of the blocking cover 18; when disassembling, it is only necessary to pull the connecting column 22 from both sides to the middle at the same time to separate the limit plate 17 from the movable groove 11, and the blocking cover 18 can be removed for cleaning, making installation and disassembly convenient.
