[0003] Based on the above, the inventors have found the following problems: the existing electric pipe cutting machines need to cut pipes of different diameters, but the electric pipe cutting machines are not convenient for quickly adjusting the distance between the cutting blade and the pipe so that the cutting blade and the pipe cutting position are aligned. At the same time, when cutting a longer pipe, since the electric cutting machine only clamps and fixes one end of the pipe inserted into it, and the portion of the longer pipe that does not need to be cut is located outside the electric cutting machine, it is not convenient to support and fix the end of the longer pipe, and it is necessary to manually support the end of the longer pipe to ensure the overall stability of the pipe, thereby reducing the practicality of the electric pipe cutting machine.
