In this way, the fixed part of the trimming mechanism 32 can make a linear motion on the long slide 22, so as to achieve the width adjustment of lawn trimming. The moving part of the trimming mechanism 32 is limited by the serpentine slide 23. When the moving part moves to the end point where the serpentine slide 23 is parallel to the linear slide 22, it moves in the vertical direction of the long slide 22, so as to achieve the depth adjustment of lawn trimming, so that a large area of ​​lawn can be trimmed at a single position, and the movement of the device is reduced.

[0018] Combination Figure 7 and Figure 8 As shown, the trimming mechanism 32 includes a trimming knife 325 for trimming the lawn through a rotary motion. The trimming knife 325 is mounted on a sliding rod 324. The trimming knife 325 is vertically arranged to the sliding rod 324. The sliding rod 324 is mounted on a mounting frame 322. The sliding rod 324 can slide freely on the mounting frame 322. A first slider 326 is installed below the sliding rod 324 through an extension rod. The first slider 326 is slidably installed in the serpentine slide 23. A second slider 329 is provided below the mounting frame 322. The second slider 329 is slidably installed in the long slide 22. In this way, the trimming mechanism 32 can ensure stable movement on the seat plate 21.

[0019] The mounting frame 322 is provided with a guide rod 327, and the extension rod arranged below the sliding rod 324 is installed on the guide rod 327.
