[0002] Pipes are indispensable basic materials in many fields such as modern construction, industrial manufacturing, agricultural irrigation, and urban water supply and drainage. Their importance is self-evident. Pipe cutting machines are used in the process of pipe processing. Existing pipe cutters generally have movable and rotating saw blades to cut pipes. Pipes are generally fed manually, which greatly burdens the processing efficiency. There are also machines that can feed automatically. When working, the pipe is pressed into the inside of the moving seat by the upper pressure structure, and then the moving seat drives it to move. When cutting next time, the upper pressure structure is released, the moving seat retreats, and then it is driven to move by the lower pressure. The simple structure improves the processing efficiency, but during the retreat of the moving seat, its lower side wall will always be in contact with the lower surface of the pipe and rub against it, which can easily scratch the pipe or cause its own wear, resulting in general use effect.
