Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1;

the pipeline comprises a pipeline 1, wherein an outer ring 11 is installed on one side of the pipeline 1, a moving piece 3 is installed inside the outer ring 11, the moving piece 3 is connected inside the outer ring 11 in a sliding mode, a fixed block 5 is installed inside the outer ring 11, and a rubber ring 6 is installed on one side of the fixed block 5;

by moving the moving member 3, the moving member 3 extrudes the rubber ring 6, one end of the rubber ring 6 is connected with the fixed block 5, the other end of the rubber ring 6 is attached to the pipeline 1, the moving member 3 extrudes the rubber ring 6, one end, far away from the fixed block 5, of the rubber ring 6 moves inwards, the rubber ring 6 deforms and is attached to the pipeline in the pipeline 1, the rubber ring 6 is attached to the pipeline in the pipeline 1 more deeply along with the movement of the moving member 3, the rubber ring 6 is attached to the pipeline in the pipeline 1 more tightly, the sealing performance is increased after the pipeline is fixed, the rubber ring 6 cannot be abraded, and when the pipeline is taken out, the moving member 3 is pulled back to the original position, the rubber ring 6 returns to the original position, and the pipeline is taken out, so that the rubber ring 6 cannot be abraded;

the driving part 2 is arranged on the surface of the outer ring 11, the outer ring 11 is connected with the driving part 2 through threads, and one end of the driving part 2 is attached to the moving part 3;

by rotating the driving part 2, the driving part 2 extrudes the moving part 3, and the moving part 3 is driven to move in the outer ring 11;
