[0025] Based on the above scheme, when the device is in use, the sleeve member 2 is first sleeved on the end 12 of the pipe 1 through the sleeve hole 21 of the sleeve member 2, and then the connecting member 4 and the pipe clamping member 3 are rotated to make the clamping groove 31 of the pipe clamping member 3 clamped on the pipe body 11 of the pipe 1 to complete the positioning of the end 12 relative to the pipe body 11, so as to quickly find the end 12 of the pipe 1 when cutting the pipe 1, and after the cutting is completed, it is only necessary to reinstall the device on the pipe 1 to complete the re-fixation of the end 12 of the pipe 1, so as to avoid the situation that the pipe 1 is scattered and knotted, and facilitate the subsequent use and storage of the pipe 1.
