In this embodiment, the connecting pipe 1 is used to be installed in the mounting hole on the supporting foundation such as a plate, and the stabilizing member 3 is pressed against the mounting hole, and then fixed to the supporting foundation through the connecting ear 31, and then the connector 2 is screwed to the two ends of the connecting pipe 1, and the connector 2 is further circumferentially limited by the clamping block 4, and finally the conduits at both ends are connected to the corresponding connector 2 to complete the installation. The adapter is suitable for connecting conduits of different specifications, and is also suitable for connecting mounting holes of different specifications on the supporting foundation, and has high connection stability.

[0026] The connector 2 also includes a positioning portion 22 and a mounting portion 23.
