[0026] Sliding side pipe 5 to both sides, so that the device reaches appropriate length, connect clamping plate 7 and corresponding fixed hole 9 by bolt, fix side pipe 5, pass two outer fixed rings 6 from one side in turn with connecting hose, connect connecting hose 2 and external pipe 4 by fixed pipe 3.
[0027] Slide cavity 10 enables side pipe 5 to smoothly slide on the outside of assembly pipe 1, greatly facilitates the adjustment of the length of the device, so that users can adjust the length of the entire device by simply sliding side pipe 5, to meet various complex connection scenarios, clamping plate 7 corresponds with fixed hole 9, and clamping plate 7 can be firmly connected with fixed hole 9 on fixed plate 8 by bolt, so as to fix the position of side pipe 5, not only improve the stability of the device, but also make the installation and disassembly process more convenient and fast.
[0028] Please refer to Figures 1-5Two outer fixed rings 6 are respectively sleeved outside the connecting rubber pipe 2 and the external connecting pipe 4, a plurality of clamping assemblies 11 are fixedly connected inside the outer fixed ring 6, the clamping assembly 11 comprises a mounting sheet 1101 fixedly connected to the inner side of the outer fixed ring 6, two support spring sheets 1102 are fixedly connected to the outer side of the mounting sheet 1101, two clamping spring sheets 1103 are fixedly connected to the other ends of the two corresponding support spring sheets 1102, two reinforcing spring sheets 1104 are fixedly connected to the two ends of the adjacent sides of the two corresponding support spring sheets 1102, a protective sleeve 12 is fixedly connected to the inner side of the outer fixed ring 6 outside the clamping assembly 11, a sealing ring 13 is fixedly connected to the inner side of the protective sleeve 12, the two sealing rings 13 are in close contact with the connecting rubber pipe 2 and the external connecting pipe 4 respectively, the two ends of the outer side of the protective sleeve 12 are located on the two sides of the mounting sheet 1101 respectively, the top end of the inner side of the protective sleeve 12 is fixedly connected with the clamping spring sheet 1103, the number of the clamping assemblies 11 inside the same outer fixed ring 6 is six, which are annularly distributed inside the outer fixed ring 6, the clamping spring sheet 1103 is curved outward, and the two reinforcing spring sheets 1104 inside the same clamping assembly 11 are fixedly connected with the corresponding mounting sheet 1101 and clamping spring sheet 1103 respectively.
[0029] When passing through the outer fixed ring 6, the pipeline will extrude the sealing ring 13, so that the clamping spring sheet 1103 pushes the support spring sheet 1102 to deform, so that the clamping spring sheet 1103 displaces outward, which is convenient for work, and then the fixed pipe 3 is inserted into the inner side of the assembly pipe 1, the clamping spring sheet 1103 is pushed by the support spring sheet 1102, so that the clamping spring sheet 1103 pushes the protective sleeve 12 and the sealing ring 13 to clamp the outer sides of the connecting rubber pipe 2 and the external connecting pipe 4, and the sealing property of the inside of the device is ensured by the protective sleeve 12 and the sealing ring 13, and the connection is protected.

This deformation not only adapts to the thickness of the pipeline, but also ensures that the clamping assembly 11 can tightly wrap the pipeline to prevent loosening during use. The resilience of the support spring sheet 1102 not only offsets the extrusion force of the pipeline on the clamping spring sheet 1103, but also pushes the clamping spring sheet 1103 to fit the pipeline more tightly through the self-restoring force of the deformation. This dynamic balance not only ensures the stability of clamping, but also ensures the sealing effect of the pipeline at the connection. The close cooperation of the protective sleeve 12 and the sealing ring 13 can effectively prevent external factors from eroding and damaging the clamping assembly 11, and the sealing ring 13 is tightly attached between the pipeline and the clamping assembly 11, forming an impregnable sealing barrier to ensure the absolute sealing of the connection, making the device exhibit high adaptability and sealing performance.
