At the same time, by adjusting the positioning piece 817 to be stuck in different positioning holes 815, the length of the sliding rod 811 extending out of the gear plate 809 can be controlled, so that the cleaning block 812 can abut against the outside of the pipeline 7 to be tested, for different sizes The pipe 7 to be tested of different sizes is cleaned. At the same time, the motor 2 901 drives the circular gear 3 904 to rotate through the rotating shaft 2 903. The circular gear 3 904 drives the mounting ring 906 to rotate through the gear ring 905, thereby driving the pipe 7 to be tested to rotate through the arc clamping block 909. At the same time, the telescopic tube 907 and the spring 2 908 can rotate the pipes 7 to be tested of different sizes. The motor 2 901 drives the circular gear 4 911 to rotate. The circular gear 4 911 drives the circular gear 5 912. The circular gear 5 912 drives the power ring 916 to rotate through the gear belt 915, thereby continuously pushing the pipe 7 to be tested to move. At the same time, the rotating shaft 4 922 drives the rotating rod 1 923 and the rotating rod 2 924 to drive the push plate 925 to move back and forth. The push plate 925 drives the air bag 926 to squeeze intermittently, thereby continuously generating airflow to be blown out from the blowing port 929. At the same time, the reciprocating mechanism can drive the connecting pipe 927 to move back and forth through the linkage block 810, thereby continuously blowing away impurities cleaned from the surface of the pipe 7 to be tested.
