[0004] The existing patent (Announcement No.: CN216912296U) discloses that a worker manually places the metal pipe in a clamping and fixing device, clamps and fixes it by the clamping and fixing device, and manually drives the carrying slide plate to move toward the metal pipe, and cuts the pipe mouth of the metal pipe by the cutting device. The driving device drives the cutting device to move back and forth, thereby cutting the pipe mouth of the metal pipe in all directions. The utility model has a simple and compact structure and can be adapted to metal pipes of various types and sizes. The polished ends of the metal pipes are neat and have high cutting quality.
