[0007] Preferably, the connecting member includes a sliding hole opened on the arc ring, and a sliding rod is slidably connected to the sliding hole, a notch matched with the sliding rod is opened on the fixed plate, an end block is fixed to one end of the sliding rod, and a square block is rotatably connected to the other end, a screw is connected to the square block through a thread, and a circular groove matched with the screw is opened on the tube body.

[0008] Preferably, a spring is sleeved on the slide rod, and one end of the spring abuts against the end block, and the other end abuts against the side wall of the fixed disk.

[0009] Preferably, a round block is fixed on the square block, and an opening matching the round block is provided on the fixing plate.

[0010] Preferably, after the two tube bodies are butt-jointed, a sealing ring is provided on the mutually abutting portions of the fixing plates of the two tube bodies.

[0011] Preferably, a rubber gasket is provided at the portion where the end of the screw rod abuts against the inner wall of the circular groove.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0013] 1. The present application rotates the square block so that the round block is aligned with the opening, and releases the thrust on the slide rod. Under the elastic force of the spring, the round block can be inserted into the opening, and the end of the screw rod can be inserted into the circular groove. The screw rod is rotated, and the screw rod can push the two fixed disks closer to each other. The spring is compressed until the ends of the two pipe bodies fit together and the docking is completed. The connection of the two pipes is more convenient and quick, eliminating the cumbersome steps.

[0014] 2. The connection between the arc ring and the connecting ring and the pipeline in this application is relatively simple and quick. After the annular ring and the connecting ring are fixed to the pipeline, the two pipe bodies are accurately docked with the cooperation of the fixing rod 1 and the fixing rod 2. Therefore, when the two pipelines are fixed later, there is no need to dock the pipelines again, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
