[0002] A lawn mower, also known as a weeding machine, a grass cutting machine, a lawn trimmer, etc., is a mechanical tool for trimming lawns, vegetation, etc. The following is a detailed introduction to the lawn mower: The lawn mower mainly consists of a cutter head, an engine, walking wheels, a walking mechanism, blades, a handrail, and a control part. In addition, it also includes main components such as a cutter, a cutter drive device, a cutter lifting device, a safety device, and a grass shielding device. The two-stroke low-power engine has the characteristics of simple structure, light weight, and large power density, and is suitable for lawn mowers.

[0003] Based on the above, the inventor found the following problems: When the existing lawn mower is in use, a two-stroke low-power engine is often adopted. The cutter head of the lawn mower is driven to rotate by a drive device through a rotating shaft to cut grass leaves. In the transmission process, the two-stroke low-power engine needs to be paired with a transmission belt to achieve power transmission. After the lawn mower is used for a long time, internal parts are prone to damage and need to be replaced. During the maintenance process of an ordinary lawn mower, it is inconvenient to adjust the position of the two-stroke low-power engine, so that the transmission belt cannot reach the specified tension, resulting in the occurrence of phenomena such as the transmission belt being loose or slipping, affecting the use effect and reducing the working efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a two-stroke low-power engine for a lawn mower is provided, with the expectation of achieving a more practical value. Summary of the Utility Model
