[0002] Gardens are an indispensable part of the urban environment. They not only provide people with a place for leisure and entertainment, but also add beautiful landscapes to the city. The lawns in gardens can not only beautify the environment, provide leisure space, but also regulate the climate, improve air quality and protect the soil. Therefore, they play an important role in garden design and management. Generally, lawns grow relatively fast. In order to keep the lawn healthy and beautiful, lawn pruning has become one of the important tasks in gardens. Regularly pruning the lawn can not only control the growth of the lawn, but also improve its density and aesthetics, ensuring the cleanliness and comfort of the garden environment.

[0003] In the prior art, the tools or cutter head components used for pruning lawns can only cut or crush grass, and cannot be changed according to the required situation. For example, when the lawn is relatively tall, a tool with a cutting function is needed for cutting, and the longer grass clippings after cutting can be collected later. When the lawn is relatively short, a tool with a crushing function is needed to crush the cut grass clippings, and there is no need to collect them later. Summary of the Utility Model
