The reciprocating saw is an electric saw which can be used for cutting various materials, and compared with a manual saw, the reciprocating saw saves time and labor and is very good in use. The reciprocating saw is a tool for sawing by a reciprocating saw blade. The reciprocating motion of the saw blade is realized by adopting the most common crank connecting rod mechanism to transmit, and converting the rotation of a crank into the reciprocating motion of a reciprocating rod on a straight line. The reciprocating saw mainly comprises two parts from the appearance, namely a saw blade and a machine body. Among these sites, the blade is most critical to the performance of the machine, and the shape, sharpness and wear resistance of the blade teeth are among the determining factors for the performance of the machine. Because the saw blade is located at the foremost end of the machine body, once the saw blade starts to work, the saw blade is punched at the foremost end, so the sharpness, the wear resistance, the shape of the saw teeth and the like of the saw blade directly influence the cutting effect of an object.
