[0024] The specific arrangement and function of the cleaning device 6 and the limiting device 7 will be described in detail below.
[0025] In this embodiment: a cleaning device 6 is arranged inside the threaded connector 3, and the cleaning device 6 includes a connecting plate 68 and an iron wire 61. The connecting plate 68 is arranged inside the threaded connector 3, and the iron wire 61 is fixedly connected to one end of the connecting plate 68. A pull handle 67 is rotatably arranged at the end of the connecting plate 68 away from the iron wire 61. The iron wire 61 is arranged inside the metal tube 1, and a circular connecting block 62 is fixedly connected to the surface of the iron wire 61.
[0026] Specifically, a plurality of equally spaced rotation grooves 63 are formed on the side surface of the circular connection block 62 , and a rotation block 64 is rotatably connected to the inner wall of the rotation groove 63 .
[0027] In this embodiment: by opening a rotating groove 63 on the side of the circular connecting block 62, a certain rotating space is provided for the rotating block 64, and the rotating block 64 can rotate, thereby reducing the situation where the rotating block 64 is fixed on the side of the circular connecting block 62, and the rotating block 64 is stuck when moving to clean the inside of the metal pipe 1, resulting in slow cleaning.
[0028] Specifically, a cleaning rod 65 is fixedly connected to one side of the rotating block 64 away from the rotating groove 63 . The cleaning rod 65 is provided to facilitate cleaning of stains adsorbed on the inner wall of the metal tube 1 .
[0029] Specifically, two stoppers 66 are fixedly connected to one side of the rotating block 64 . The two stoppers 66 are provided to limit the rotation angle of the rotating block 64 to a certain extent.
[0030] In this embodiment: a limiting device 7 is provided on the lower surface of the connecting plate 68 , and the limiting device 7 includes a rubber rod 71 and a limiting hole 73 . The rubber rod 71 is fixedly connected to the lower surface of the connecting plate 68 , and the limiting hole 73 is opened inside the threaded connector 3 .
[0031] In this embodiment, by providing a limiting hole 73 on the inner wall of the threaded connector 3 , the position of the rubber rod 71 can be limited, thereby reducing the possibility that the connecting plate 68 is easily rotated inside the threaded connection.

[0034] Working principle: The metal bellows is generally installed at the bottom of the kitchen sink to connect the sink with the sewer pipe, and to transport the debris inside the kitchen sink to the sewer pipe for circulation. When the device needs to be used, the user pulls the handle 67, and the movement of the handle 67 drives the wire 61 to move. When the wire 61 moves, it drives the circular connecting block 62 to move. When the circular connecting block 62 moves upward, it drives the rotating block 64 to move. The lower stopper 66 on the rotation abuts against the lower surface of the circular connecting block 62 to limit the rotating block 64, and the rotation drives the cleaning rod 65 to clean and dredge the inside of the metal pipe 1. By setting the cleaning device 6, the inner wall of the metal pipe 1 is effectively cleaned and dredged, which plays a role in cleaning the metal pipe 1, reduces the risk of grease being easily absorbed by the inside of the metal pipe 1 when the device is in use, causing oil stains to accumulate and block the inner wall of the metal pipe 1, resulting in the slow discharge of sewage from the metal pipe 1, thereby improving the practicability of the device.
[0035] When the device needs to be used, the user matches the rubber ball 72 with the limiting hole 73, and then presses the connecting plate 68 to drive the rubber rod 71 to move and apply pressure to the rubber ball 72. Then the rubber ball 72 passes through the limiting hole 73 and comes out at one end of the limiting hole 73. The rubber rod 71 limits the connecting plate 68 inside the limiting hole 73. By setting the limiting device 7, the iron wire 61 is effectively restricted, which plays a role in stabilizing the iron wire 61, reduces the situation where the iron wire 61 is difficult to limit when the device is in use, and is easy to fall into the metal pipe 1, thereby improving the stability of the device.
