After the positioning work of the assembly ring 3061 is completed, the assembly ring 3061 is threadedly connected to the main pipeline connector. Then, the hand-held column 303 is used to drive the main through ring 302 to move toward the inside of the main pipeline. During the movement, the main through ring 302 will separate foreign matter from the main pipeline. When the main through ring 302 cannot move further, pull the main through ring 302 back to its original position. After the main pipeline is unblocked, connect the assembly ring 3061 to the main pipeline The parts are separated, and then the assembly ring 3061 that matches the branch pipe is replaced. The new assembly ring 3061 is threadedly connected to the branch pipe connector after being positioned through two positioning bolts 3062 and two positioning holes. Then, the branch ring 305 is driven by pressing the circular plate 310 to insert into the branch pipe to separate the foreign matter from the branch pipe. When the branch ring 305 can no longer move, the force applied to the pressing circular plate 310 is removed. Then, the above branch pipe unclogging steps are repeated to complete the unclogging work of all branch pipes. Finally, the foreign matter in the multi-channel pipe 2 can be poured out or sucked out. Each pipe only needs to be cleaned once, and there is no need to clean it multiple times, which reduces the workload of the unclogging work.
