[0032] Working principle: when the user needs to cut the pipe, first rotate the fixing assembly to the position corresponding to the cutter body 1, so that the screw assembly 2 26 and the screw assembly 1 17 are in a coaxial state, and then open the cutter body 1 and the fixing assembly 3 in turn. At this time, the user adjusts the clamping member 6 according to the size of the pipe. After adjustment, the cut pipe is directly placed between the two clamping members 6 from the opening, and the fixing assembly 3 and the cutter body 1 are closed in turn, so that the pipe can be held tightly. The user turns the screw to move the cutting device 2 to abut the pipe, turns on the cutting device 2 switch, holds the pipe with one hand and slightly rotates the cutting member with the other hand to make the milling cutter cut into the inside of the pipe. After the milling cutter penetrates the inner wall of the pipe, the cutting device 2 is rotated one circle to cut the pipe. The whole process is simple and the cutting efficiency is high. The clamping member 6 is easy to adjust to suit the sizes of pipes of different sizes, and the cost of use is lower.
