[0003] When pipes are produced in the factory, in order to test the quality of the pipes, the pipes need to be cut off and subjected to a water-tightness test to test the quality of the pipes.

[0004] The prior art patent document with publication number CN209432382U provides a portable device for pipeline water-tightness test, which can improve the sealing performance between the wellbore and the pipeline and improve the experimental effect through the cooperation between the first sealing gasket, the second sealing gasket, the sealing plate and the fixing bolts.

[0005] The above-mentioned prior art performs a water-tightness test by strengthening the sealing performance. However, when performing a water-tightness test on a pipeline in a factory, workers use bolts to fix a sealing plate at one end of the pipeline, strengthen the sealing performance through a sealing gasket, and inject water into the pipeline to perform a water-tightness test. The operation is relatively cumbersome and not convenient enough. It is not possible to perform a water-tightness test on the pipeline very simply, and it cannot meet people's needs. Therefore, we need a pipeline water-tightness test device. Utility Model Content
