By setting the third limiting frame 910, the roller 911 can be limited, so that the roller 911 is in contact with the outer surface of the pipe. When the roller 911 is squeezed against the inner wall, the roller 911 can rotate stably. The gear ring 912 is meshed with the gear column 94. The outer surface of the fixing frame 99 is penetrated by a threaded ring 913. The inner cavity of the threaded ring 913 is rotatably connected with a threaded rod 914. The end of the threaded rod 914 is rotatably connected with a rotating sleeve 915. The outer surface of the rotating sleeve 915 is fixedly connected with a cutting knife 916. By setting the threaded ring 913, the threaded rod 914 can be limited, so that the distance between the rotating sleeve 915 and the cutting knife 916 and the end of the pipe can be changed. The rotating sleeve 915 The setting can ensure that the cutting knife 916 is always in contact with the pipe when the threaded rod 914 rotates, and will not rotate with the threaded rod 914. When in use, the operator inserts the positioning block 96 into the inner cavity of the positioning frame 37, and then rotates the threaded rod 914 until the cutting knife 916 is in tight contact with the pipe. Then, the servo motor 92 is connected to the power supply and the switch of the servo motor 92 is turned on, so that the rotating rod 93 drives the gear column 94 to start rotating.
