[0034] When two pipes need to be connected, it is only necessary to insert the second extension fixture 8 into the annular groove 13, push the third connecting pipe 5 to the corresponding position, and then insert the column 15 into the first groove 9 to complete the installation. When disassembling, the column 15 is pulled out of the first groove 9, and then the third connecting pipe 5 automatically returns to its original position under the rebound of the second spring 20, so that disassembly is achieved, which is more convenient and effective.

[0035] Embodiment 2

[0036] On the basis of the first embodiment, a slide groove 4 is provided, and a plurality of slide grooves 4 are provided, and the plurality of slide grooves 4 are equidistantly arranged linearly on the surface of the first connecting tube 1. The number of sliders 19 is consistent with the slide groove 4, and the slider 19 slides in the slide groove 4. A plurality of first vertical blocks 11 are provided, and the plurality of first vertical blocks 11 are equidistantly arranged linearly on the surface of the first connecting tube 1. The surface of the vertical block is fixedly connected with a first column 12, and the surface of the first column 12 is sleeved with a second spring 20. The other end of the second spring 20 is sleeved on the second column 17 and the end is fixed to the end surface of the second groove 16. The second column 17 is fixed to the end surface of the second groove 16. The first vertical block 11, the first column 12 and the second spring 20 are located inside the second groove 16.

[0037] During use, when pushing the third connecting tube 5, the slider 19 can slide in the slide groove 4 to avoid blockage, and the third connecting tube 5 can be easily moved. The second spring 20 can give the third connecting tube 5 a pulling force when the third connecting tube 5 completes positioning, thereby enhancing the stability of the third connecting tube 5. When disassembly is required, the second spring 20 can give the third connecting tube 5 an elastic force, thereby driving the third connecting tube 5 to automatically return to its original position, which is more convenient and effective.

[0038] Embodiment 3

[0039] On the basis of the second embodiment, a second sealing ring 14 is fixed on the inner surface of an annular groove 13, a second extension fixture 8 is inserted into the annular groove 13, a first sealing ring 10 is fixed on the end surface of the second connecting pipe 2, the first sealing ring 10 is located on the periphery of the second extension fixture 8, two second grooves 16 are provided, the two second grooves 16 are evenly located on the surface of the second connecting pipe 2, a column 15 is inserted into the second groove 16, a through hole 18 is provided on the surface of the first extension fixture 3, the through hole 18 matches the second groove 16, the column 15 is inserted into the through hole 18, a first spring 7 is sleeved on the surface of the column 15, a vertical plate 6 is fixedly connected to the end surface of the column 15, the vertical plate 6 is in the shape of a square plate, one end of the first spring 7 is fixedly connected to the surface of the first extension fixture 3, and the other end of the first spring 7 is fixedly connected to the lower surface of the vertical plate 6;

[0040] When in use, the second extension fixture 8 can be inserted into the annular groove 13, and the end face of the second extension fixture 8 abuts against the second sealing ring 14, and the end face of the first connecting pipe 1 abuts against the first sealing ring 10. The presence of the two sealing rings can achieve sealing of the pipeline to avoid leakage. When it is necessary to move the column 15, it is only necessary to manually pull the vertical plate 6, and then the column 15 returns to its original position under the action of the first spring 7. The structure is simple and practical.

[0041] Working principle: In actual use, when two pipes need to be connected, it is only necessary to insert the second extension fixture 8 into the annular groove 13, push the third connecting pipe 5 to the corresponding position, and then insert the column 15 into the first groove 9 to complete the installation. When disassembling, the column 15 is pulled out of the first groove 9, and then the third connecting pipe 5 automatically returns to its original position under the rebound of the second spring 20, so that disassembly is more convenient and effective. This avoids the problem that traditional PVC pipes can only be removed by cutting after being fixed and connected by glue. Such installation and connection method is not only troublesome but also inconvenient for later disassembly, resulting in waste of resources.
