In this setting, when the asynchronous motor 201 is running, it will be able to drive the rotating rod 2011 to rotate, and when the rotating rod 2011 rotates, it will be able to drive the mobile sleeve 2015 to rotate, because the mobile sleeve 2015 is provided with a guide slot 2013, and the guide slider 2014 is slidably provided on the guide slot 2013, and because the guide slider 2014 is connected to the slider 2022 in the second sliding mechanism through the telescopic rod 2023, it is possible to ensure that the guide slider 2014 moves horizontally.

[0047] Embodiment 2: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figures 1 to 8 As shown, a vegetation pruning device for garden engineering construction, the second cutting knife 3011 and the third cutting knife 3012 are respectively fixedly installed with a first rotating shaft 302 and a second rotating shaft 3021 at one end close to the shear chassis 1023, and the first rotating shaft 302 and the second rotating shaft 3021 are respectively installed with a second bearing 3022 at one end away from the second cutting knife 3011 and the third cutting knife 3012.

The first rotating shaft 302 and the second rotating shaft 3021 can drive the second cutting knife 3011 and the third cutting knife 3012 to rotate, and the vegetation can be trimmed at this time.

[0048] like Figures 1 to 8 As shown, in a specific embodiment, the first conveyor belt 3023 and the second conveyor belt 3024 are respectively sleeved on the first rotating shaft 302 and the second rotating shaft 3021, and the other ends of the first conveyor belt 3023 and the second conveyor belt 3024 are respectively sleeved on the connecting rod 2042, and a sealing plate 3013 is installed in the shear chassis 1023 on the side of the first conveyor belt 3023 and the second conveyor belt 3024 close to the first cutting knife 301, the second cutting knife 3011 and the third cutting knife 3012. In this arrangement, it is ensured that when the rotating rod 2011 rotates, it can also drive the connecting rod 204 to rotate, and the connecting rod 204 can drive the connecting rod 2042 to rotate through the universal joint 2041, and the first cutting knife 301 can be driven to rotate through the connecting rod 2042.

[0050] Embodiment 3: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figures 1 to 8 and Fig.10 As shown, the second rotating components 402 are disposed on the opposite side walls of the shear chassis 1023, and the inner cavities of the two second rotating components 402 are both provided with placement plates 4013, and the second rotating components 402 and the placement plates 4013 are plugged with latches 4022, and a positioning plate 4021 is disposed on one side wall of the second rotating component 402. In this arrangement, it is ensured that when the placement plates 4013 rotate to a certain angle, they will not continue to rotate, and the arrangement of the latches 4022 ensures that the placement plates 4013 can be limited.

[0051] like Figures 1 to 10 As shown, further, each first rotating assembly 2034 and each second rotating assembly 402 includes two limit plates 4023, each limit plate 4023 is respectively fixedly connected to the connecting plate 2031, the second rectangular mounting cylinder 1022 and the shear chassis 1023, and each limit plate 4023 is installed with a bearing at one end opposite to the other, and the inner cavity of the two bearings is provided with a rotating rod 4024. In this configuration, the components of the first rotating assembly 2034 and the second rotating assembly 402 are determined to ensure that they can respectively drive the movable rod 2033 and the placement plate 4013 to rotate.

[0052] The implementation principle of a vegetation pruning device for garden engineering construction in this embodiment is as follows:

[0053] First, the staff pushes the mobile support unit 100 to move. When the mobile support unit 100 moves to the vegetation of the garden project construction, when it is necessary to trim the individual garden vegetation, the staff takes out the latch 4022 provided on the vegetation straightening unit 400, and rotates the first C-shaped plate 401 and the second C-shaped plate 4011, so that the first C-shaped plate 401 and the second C-shaped plate 4011 can wrap the garden vegetation;

[0054] At this time, the staff controls the asynchronous motor 201 to start through the controller. When the asynchronous motor 201 is running, it can drive the rotating rod 2011 to rotate. When the rotating rod 2011 rotates, it can drive the movable sleeve 2015 to rotate. Because the movable sleeve 2015 is provided with a guide slot 2013, and the guide slot 2013 is slidably provided with a guide slider 2014, because the guide slider 2014 is connected by the telescopic rod 2023 and the slider 2022 in the second sliding mechanism, it can ensure that the guide slider 2014 moves horizontally. At the same time, because the connecting plate 203 is fixedly installed on the telescopic rod 2023, when the connecting plate 203 moves, it can drive the movable rod 2033 through the connecting plate 2031 with the assistance of the first rotating component 2034 to pull the second rectangular installation cylinder 1022 to adjust the angle in the inner cavity of the first rectangular installation cylinder 1021 with the assistance of the third sliding mechanism;

[0055] When the rotating rod 2011 rotates, it can also drive the connecting rod 204 to rotate, and the connecting rod 204 can drive the connecting rod 2042 to rotate through the universal joint 2041, and the first cutting knife 301 can be driven to rotate through the connecting rod 2042. When the first cutting knife 301 rotates, the first transmission belt 3023 and the second transmission belt 3024 can respectively drive the first rotating shaft 302 and the second rotating shaft 3021 to rotate, and the first rotating shaft 302 and the second rotating shaft 3021 can drive the second cutting knife 3011 and the third cutting knife 3012 to rotate, and the vegetation can be trimmed at this time. Because the angle of the second rectangular mounting tube 1022 can be adjusted, the up and down rotation angle of the second rectangular mounting tube 1022 in the first rectangular mounting tube 1021 is about 30 degrees, so the angle of the shear chassis 1023 can be adjusted, so that the angles of the first cutting knife 301, the second cutting knife 3011 and the third cutting knife 3012 can be adjusted, so they can be adjusted;

[0056] When the angle of the shear chassis 1023 is adjusted, the position height can be changed through the first C-shaped plate 401 and the second C-shaped plate 4011, so that one end of the first C-shaped plate 401 and the second C-shaped plate 4011 can pull the vegetation, ensuring that the vegetation will not be forced to move backward to a certain extent when pruning the vegetation.
