[0024] In specific implementation, seamless steel pipes can be used to transport gases or liquids such as oil, natural gas, coal gas, and water. When processing seamless steel pipes, a pipe cutting device is required to cut them. When collecting the dust generated during the processing of the pipe cutting device, the exhaust fan 7 is started, and the exhaust fan 7 transmits the suction force to the top of the body 1 through the filter screen 9 and the through hole 17, so that the dust falling on the top of the body 1 is sucked into the collection box 8 for collection. The filter screen 9 blocks the dust and prevents the dust from entering the exhaust fan 7. When the cutting blade 4 rotates and moves downward to cut the steel pipe, the connecting arm 3 will also rotate. When the connecting arm 3 rotates, it will press down the pressure rod 15. When the pressure rod 15 moves, it will squeeze the second spring 16. At the same time, the bottom of the pressure rod 15 will rotate the rotating rod 13 through the roller. The cleaning brush 12 is pressed against the bottom surface of the filter 9, and the cleaning brush 12 is pressed against the bottom surface of the filter 9. When the cleaning brush 12 moves downward, the filter 9 on one side can be cleaned, and the first spring 11 is squeezed at the same time to prevent dust from being adsorbed on the filter 9 and clogging the filter 9. When the steel pipe is cut, the cutting blade 4 is rotated and reset. At this time, the second spring 16 is also reset to push the pressure rod 15 to move upward. After the cleaning brush 12 loses the squeezing force at the top, the second spring 16 is also reset to push the cleaning brush 12 to move upward and clean the filter 9 on one side again. When the pipe is cut, the collecting box 8 can be pulled out of the body 1 to clean the dust in the collecting box 8. The above operation can facilitate the cleaning of the dust generated during the processing of the pipe cutting device.

After docking, release the pull rod 23, and the third spring 21 will reset, pushing the limit block 20 to move and engage with the connecting rod 18 to complete the fixation of the movable seat 6.
