After the water pipe sealing test is completed, the pressure on the push plate can be released to reset the spring, thereby driving the rubber damper and the push rod to return to their original positions, which is convenient for the next use.

[0025] 2. In the present application, the first sealing damper and the second sealing damper can be replaced by cooperating with the screw and the threaded sleeve, so as to facilitate sealing of water pipes of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS
