[0002] With the rapid development of the automotive industry, pipe fittings, as important automotive components, have received increasing attention. After production, pipe fittings undergo airtightness testing. This typically involves securing the pipe with a fixture, then using matching sealing plugs to seal and inflate both ends. The air pressure is then used to determine if the pipe is leak-tight.

[0003] However, although the existing leak detection device can determine whether a pipe is leaking by using air pressure, it is inconvenient to determine where the leak is occurring in the pipe, mark the location of the leak, and is inconvenient to use. In addition, the existing leak detection device does not have a rotating structure and cannot rotate the pipe after clamping it, making it inconvenient to inspect the pipe. Therefore, there is an urgent need for a leak detection device for automotive pipes to solve the above problems. Utility Model Content
