[0037] When cutting, first start the displacement motor 16 to drive the slide rail 7 through the threaded connection of the displacement rod 17 and the slide 8, so that the slide 8 slides as a whole away from the cutting seat 2 at one end of the base 1, until the slide 8 cannot continue to slide at the end of the slide rail 7 where the displacement motor 16 is located. At this time, the pipe to be cut is hoisted to the upper side of the slide rail 7 and aligned with the cutting seat 2, and then the displacement motor 16 is started to make the slide 8 drive the mounting disc 9 fixed on the connecting rod 10 to enter the inside of the pipe to be cut.
