[0002] A lawn mower is a commonly used gardening tool, which is often used to cut and trim weeds in lawns, gardens, pastures and other places. It has various structural designs, and the most common one is a handheld type. It is mainly composed of a motor, a transmission machine, a power supply and a cutter head, and the motor drives the cutter head to rotate at high speed. However, garden tools such as lawn mowers generally have the problems of single function and narrow application range. Except for a few cases, after users purchase such garden tools, the tools are idle most of the time. However, due to practical needs, they have to keep such tools on hand. In addition, for the long-term maintenance of garden courtyards and other places, users often need to keep a series of electric garden tools with various functions on hand. Each tool has a low utilization rate and is idle for a long time, which not only increases unnecessary cost burden, but also does not maintain the state of the tool due to long-term idleness.
