[0002] The water supply and drainage pipeline is a pipeline system project that transports and distributes industrial water supply and domestic drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. Water is an indispensable substance in daily life, and the transportation of water depends on the transportation of drainage pipes. Therefore, it is often necessary to install various drainage pipes on buildings. For the convenience of construction, drainage pipes often need to be spliced. Most of the existing pipes are connected by flanges. When connecting two pipes, the two flanges need to be accurately aligned first. If the threaded holes are misaligned, they cannot be fixed and installed. The installation method is relatively complicated and prone to offset, which will cause some gaps between the two flanges and cause water leakage at the connection of the drainage pipe.

A buckle groove 304 is opened at the bottom of the front end of the lock buckle 303, and the lock buckle 303 is engaged with the surface of the pin rod 302 at the corresponding end through the buckle groove 304.

[0027] During specific use: when the first clamp 101 and the second clamp 102 are combined, the mounting seats 301 at the other ends of the first clamp 101 and the second clamp 102 are close to each other, and a pin rod 302 is installed in the middle of the two mounting seats 301.
