[0002] A reciprocating saw is a machine that uses a motor to drive the saw blade to reciprocate at high speed. It has an electronic speed regulation function and can cut at different speeds for different materials; during the reciprocating movement of the saw blade, the reciprocating saw can imitate the user When cutting, the saw blade is moved up and down to achieve efficient and labor-saving cutting; a rotatable bottom plate is installed at the bottom of the reciprocating saw, which is convenient for users to use various tools; It is difficult to cut straight materials; in addition, it is difficult to cut standard arcs when cutting arcs; for this reason, people have designed some auxiliary tools, but before cutting, the auxiliary tools need to be clamped on the material plate, The operation is cumbersome, and when encountering irregularly shaped materials, it is difficult for auxiliary tools to locate
