DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] Reference Figure 1-Figure 3 , a chainsaw pruning structure of a garden drone, including a chainsaw body 4, on which two sawtooth bars 5 arranged up and down are installed, and the driving action of the chainsaw body 4 on the sawtooth bars 5 to make them move back and forth left and right is a prior art, and its working principle is not explained in detail here, a support assembly is connected to the chainsaw body 4, and the support assembly includes a straight connecting rod 1 and an arc-shaped connecting rod 2, and one end of the straight connecting rod 1 and the arc-shaped connecting rod 2 are rotatably connected together, and the support assembly is used to connect the drone to the chainsaw body 4, and a rotating groove 12 is opened on the straight connecting rod 1, and a driving motor 13 is rotatably installed in the rotating groove 12, and when the threaded rod 10 rotates, the driving motor 13 is rotatably installed in the rotating groove 12 to adapt to the change of angle;

[0026] A driving motor 13 is rotatably installed on the straight connecting rod 1, and a threaded rod 10 is fixedly connected to the driving end of the driving motor 13. A movable component is slidably connected to the surface of the arc-shaped connecting rod 2, and the movable component includes a slider 9 and a connecting sleeve 11. The threaded rod 10 is threaded through the connecting sleeve 11, and a slide groove 3 is provided on the arc-shaped connecting rod 2. Two sliders 9 are provided and rotatably installed on both sides of the connecting sleeve 11. The two sliders 9 are slidably connected on both sides of the slide groove 3. When the driving motor 13 drives the threaded rod 10 to rotate through the driving end, the relative position of the connecting sleeve 11 can be changed. As the connecting sleeve 11 moves, the angle of the arc-shaped connecting rod 2 can be changed through the sliders 9 on both sides, thereby changing the angle between the arc-shaped connecting rod 2 and the straight connecting rod 1.

[0027] The electric saw body 4 is rotatably connected to the lower end of the arc-shaped connecting rod 2. An elastic mechanism is arranged between the electric saw body 4 and the arc-shaped connecting rod 2. The elastic mechanism includes a spring 8. The arc-shaped connecting rod 2 is divided into an upper part, a middle part, and a lower part. The movable component is slidably connected in the middle position. The upper part and the lower part are arranged parallel to each other. The arc-shaped connecting rod 2 forms a U-shaped structure through the upper part, the middle part, and the lower part. The angle of the middle part is adjusted to achieve the overall angle. There is space in the middle of the U-shaped structure, which is convenient for cutting. There is enough space to avoid extra branches.

[0028] Sharp teeth are provided on both sides of the sawtooth bar 5, and the angles of the two sawtooth bars 5 are staggered with each other. When the electric saw body 4 is started, the two sawtooth bars 5 move back and forth alternately to achieve the shearing effect on the branches. A connecting block 14 is provided at the upper end of the straight connecting rod 1, and a plurality of holes are opened on the connecting block 14. The upper end of the straight connecting rod 1 is connected to the drone through the connecting block 14, and the installation connection effect is achieved by bolts passing through the holes.

[0029] In the embodiment of the applied technical solution, the structure is fixedly installed at the lower position of the drone through the connecting block 14. When it is necessary to cut specific branches, the position of the electric saw body 4 is adjusted according to the position of the branches. The arc-shaped connecting rod 2 is an arc-shaped structure. When the electric saw body 4 is moved, it can directly cross the surrounding branches, which facilitates the movement and penetration of the electric saw body 4. The electric saw body 4 is started to realize the back and forth movement of the two saw teeth 5, so that the branches can be sawed off to achieve the pruning effect.

[0030] The driving motor 13 can drive the threaded rod 10 to rotate through the driving end. The rotation of the threaded rod 10 can realize the change of the relative position of the connecting sleeve 11. In the process of changing the position, the connecting sleeve 11 can drive the sliders 9 on both sides to move simultaneously, and then the sliders 9 move back and forth on the surface of the arc-shaped connecting rod 2. The relative distance between the connecting sleeve 11 and the driving motor 13 changes, and the angle between the arc-shaped connecting rod 2 and the straight connecting rod 1 will change adaptively. By changing the angle of the arc-shaped connecting rod 2 relative to the straight connecting rod 1, the angular position of the serrated bar 5 can be changed to meet the needs of different pruning conditions and improve the adaptability to vegetation pruning.

[0031] 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.
