[0023] Specifically, the rotating shaft 2 is used to drive the movable ring 5 to slide on the external thread 3, thereby achieving the pulling of the telescopic frame 7. After being pulled, the telescopic frame 7 can unfold its structure so that the brush plate 8 can be pushed outward. The brush plate 8 will continue to push out until it is completely in contact with the inner wall of the pipe. In this process, the movable ring 5 will slide inside the fixed sleeve 10, and the positioning column 9 will also slide with the movement of the movable ring 5, thereby limiting the position of the movable ring 5. During the cleaning process, the recovery bucket 15 will play a role in collecting dirt. Since the brush plate 8 can fit tightly to the inner wall of pipes of different calibers, when cleaning dirt, the brush plate 8 can effectively scrape off the dirt on the inner wall of the pipe. This ensures the effectiveness of the cleaning work. At the same time, tight fitting and efficient cleaning of pipes of different calibers are achieved.

[0025] Specifically, the plug plate 14 can be rotated on one side of the connecting plate 12 by the connecting shaft 13, so that the plug plate 14 can be inserted into the recovery bucket 15 by rotating the plug plate 14, thereby fixing the recovery bucket 15, thereby achieving the effect of connecting the recovery bucket 15.

[0026] Reference Figure 1 and Figure 3 , the outer wall of the rotating shaft 2 is slidably connected with a recovery bucket 15, and the outer wall of the insert plate 14 is slidably connected to the inside of the recovery bucket 15; the inside of the recovery bucket 15 is slidably connected with a slide rod 16, one end of the slide rod 16 is rotatably connected with a top block 17, and the other end of the slide rod 16 is fixedly connected with a first push plate 18; the outer wall of the top block 17 is slidably connected to the inside of the recovery bucket 15, and the outer wall of the first push plate 18 is slidably connected to the inside of the rotating shaft 2; the outer wall of the slide rod 16 is sleeved with a second spring 24, one end of the second spring 24 is fixedly connected to the inside of the rotating shaft 2, and the other end of the second spring 24 is fixedly connected to the first fixing ring 19; the inside of the recovery bucket 15 is slidably connected with a pull rod 20, and the inside of the pull rod 20 is fixedly connected with a pull ring 21; the outer wall of the pull rod 20 is sleeved with a first spring 23, one end of the first spring 23 is fixedly connected to the inside of the recovery bucket 15, and the other end of the first spring 23 is fixedly connected to the second fixing ring 22;

[0027] Specifically, first pull the pull ring 21 to make the pull rod 20 slide inside the recovery bucket 15.
