When the at least one mounting seat3is changed from the loosening position to the pressing position, the at least one mounting seat3is moved to correspond to the at least one anti-disconnection block25to inhibit outward deformation of the at least one anti-disconnection block25that is along the radial direction of the drain pipe body1.

Referring toFIG.14, embodiment 9 of the present disclosure is disclosed. The difference between this embodiment and embodiment 1 is that the at least one connecting seat2is integrally formed on the drain pipe body1by overmolding.

The aforementioned embodiments are merely some embodiments of the present disclosure, and the scope of the disclosure is not limited thereto. Thus, it is intended that the present disclosure cover any modifications and variations of the presently presented embodiments provided they are made without departing from the appended claims and the specification of the present disclosure.
