[0002] In the current construction projects, water conservancy projects and agricultural irrigation, PVC well drilling pipes are an important pipe material, which has been widely used due to its excellent corrosion resistance, light weight, high strength and easy installation. However, in actual use, it is often necessary to expand the PVC well drilling pipe according to the needs of the project to adapt to different working environments and flow requirements.

By sliding the slide plate 4 on the slide bar 3, the lateral movement of the two groups of mounting plates 1 can be controlled.

[0027] The number of the mounting seats 6 is several groups and they are arranged in a ring shape. A plurality of groups of mounting seats 6 arranged in a ring shape are installed, and the plurality of groups of sockets 8 installed in this way can form a ring-shaped area to adapt to the PVC drilling pipe.
