[0002] A lawn mower is a tool used to remove weeds and messy vegetation on lawns. It is also called a lawn mower, lawn mower, lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. It consists of a cutter disc, an engine, running wheels, a walking mechanism, blades, armrests, and a control part. The cutter disc is mounted on the running wheels, the cutter disc is equipped with an engine, and the engine output shaft is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of weeding workers and reduces a lot of human resources.

[0003] When using a lawn mower, you need to hold the handrail to push the machine for weeding. You need to keep balance during the weeding process. You need to hold the lawn mower firmly on the pole to ensure that your hands have sufficient support. Due to the vibration of the machine and personal factors, it is easy for the hand to loosen on the handrail. If you do not tighten it again in time, the operation may be dangerous.
