[0002] At present, the pruning of green belts in gardens generally relies on handheld trimmers to trim the green belts. Long-term pruning will cause arm pain, which is not conducive to long-term labor. At the same time, it is difficult to maintain the flatness of the pruning by hand-held pruning, which will affect the appearance. In addition, the pruning difficulty will be increased for green belts that are far away and cannot be reached by humans. At the same time, when pruning the lawn in the garden, it is necessary to change the equipment for pruning. For this purpose, it is necessary to carry different types of equipment for gardening operations, which increases the difficulty of carrying. For the pruning of the lawn, in order to save time and effort, a hand-push lawn mower is generally used for cutting. When encountering obstacles during the cutting process, it is necessary to turn back first and then push the lawn mower to bypass the obstacles from both sides. It is very inconvenient to push, and it is easy to damage the mowing blade when touching the obstacle.
