When one end of the second joint 4 abuts against the inside of the first joint 2, the limiting rod 5 is released. By using the reset spring 9, the limiting rod 5 can be automatically entered into the limiting hole 6 on the second joint 4, so that the pipes can be connected. When the pipes need to be disassembled for maintenance, the limiting rod 5 is pulled to make one end of the limiting rod 5 away from the limiting hole 6, and then the second pipe 3 is pulled. When the second joint 4 on the second pipe 3 is away from the first joint 2 on the first pipe 1, that is, The first pipe 1 and the second pipe 3 can be disassembled, so as to facilitate their disassembly and maintenance, which is beneficial to improving their practicality. After the first pipe 1 and the second pipe 3 are fixedly installed, the sealing sleeve 12 on the second pipe 3 is rotated so that the internal thread 13 on the sealing sleeve 12 is threadedly connected with the external thread 14 on the outer surface of the first joint 2, and the sealing sleeve 12 can be fixed between the second joint 4 and the first joint 2. Then, by using the second sealing ring 15 in the sealing sleeve 12, the first joint 2 and the second joint 4 can be sealed, which reduces the risk of leakage and is beneficial to improving its sealing performance.
