[0002] A saw is a piece of mechanical equipment mainly used to cut wood, metal and other materials of different types and shapes. The working principle of a saw is to use a series of teeth on the saw blade to cut the material into the required shape and size. Saws are widely used in woodworking, metal processing, construction and manufacturing industries. Saws can be divided into two types: manual saws and automatic saws. Manual saws require workers to manually move the saw teeth to complete the cutting, while automatic saws can automatically complete the cutting work through computer programs. Depending on the purpose and material, saws can also be divided into woodworking saws, metal saws, stone saws, plastic saws, etc. In order to ensure that the saw machine always keeps a stable state when cutting wood, it needs to be limited when cutting wood. Traditional limiting methods mostly involve manually pressing the wood, which is very dangerous to operate. In order to improve this situation, a limiting device for a saw is proposed.
