then, the connecting pipe 2 is placed between the two sections of cut pipelines, then the cut sealing part 1 is taken away, because the two ends of the connecting pipe 2 can stretch out and draw back, when the cut sealing part 1 is taken away, the two ends of the connecting pipe 2 extend out, the pipe diameters of the two ends are set to be smaller than the inner diameter of the original pipeline, and then the two ends extend out, finally the two ends of the connecting pipe 2 enter the original pipeline, and further the two ends of the cut pipeline are communicated, so that the maintenance of the pipeline is completed, because the length of the cut part does not need to be measured, the length of the cut part can be automatically adapted, so that the efficiency of the pipeline maintenance is improved, the time for maintaining the pipeline is saved, the time for outward diffusion of media in the pipeline is reduced, and the waste of conveying media is reduced; when the pipeline is maintained, the fixed clamp frames 11 are placed on two sides of a damaged pipeline, the movable clamp frames 12 are stirred, the bayonets on the movable clamp frames 12 are clamped in the clamping grooves on the fixed clamp frames 11, the movable clamp and the fixed clamp frames 11 completely clamp the pipeline, the cutting and sealing device can be stably fixed on the pipeline, the smooth cutting process and the accuracy of a cutting position are guaranteed, and the bayonets and the clamping grooves are locked, so that the pipeline cutting device is simple in structure and easy to operate; after the cutting sealing device is fixed, the hand wheel 17 is rotated, the screw rod 16 and the cutter 15 move towards the direction of the pipeline, the pipeline is further cut off along with the rotation of the hand wheel 17, the damaged pipe is further cut off, meanwhile, the cutter 15 is in contact with the fixed clamping frame 11 and the side face of the movable clamping connection when the cutter 15 cuts off the pipeline, meanwhile, due to the fact that the first sealing ring 14 is arranged, the positions between the cutter 15 and the fixed clamping frame 11 and the movable clamping connection are in a sealed state, the medium in the pipeline is prevented from flowing outwards, the time that the pipeline is in an unsealed state is shortened when maintenance is conducted, and the waste of conveying media is reduced; when the sealing part 1 is cut off to cut off a damaged pipeline, the connecting pipe 2 is placed at a position coaxial with the original pipeline, the elastic part 22 is compressed, the movable pipe 21 retracts into the extension pipe 23, one end face of the movable pipe 21 abuts against one side face of the cutter 15, the hand wheel 17 is rotated, the cutter 15 is further away from the pipeline, when the cutter 15 is completely away from the pipeline, the movable pipe 21 loses the limit in the axial direction and extends outwards under the elastic action of the elastic part 22, the movable pipe 21 enters the original pipeline, the pipeline communication between the two cut ends is realized, the pipeline maintenance is completed, the length of the cut part can be automatically adapted without measuring the length of the cut part, the pipeline maintenance efficiency is improved, the pipeline maintenance time is saved, and the outward diffusion time of media in the pipeline is reduced, thereby reducing the waste of the conveying medium; because in the installation process, the movable pipe 21 is driven by the elastic part 22 to automatically pop up and enter the original pipeline, so that the pipeline is connected without manual installation, the pipeline maintenance time is shortened, and the pipeline maintenance speed is increased.

While the present invention has been described with reference to the embodiments shown in the drawings, the present invention is not limited to the embodiments, which are illustrative and not restrictive, and it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims.
