[0030] Working Principle: A sealing sleeve 2 is installed at the bottom of the main sealing cover 1, with a snap-fit ​​top ring 15 fixed at its top. A bottom snap-fit ​​groove 11 is annularly opened at the bottom of the main sealing cover 1 near the edge. The top of the snap-fit ​​top ring 15 can snap onto the inner side of the bottom snap-fit ​​groove 11. At this time, the sealing sleeve 2 is initially positioned at a suitable position at the bottom of the main sealing cover 1. The top opening end of the hose is inserted into the groove structure at the bottom of the main sealing cover 1, and the top end of the hose is inserted into the inner sealing groove of the main sealing cover 1, so that the hose and the main sealing cover 1 are initially connected. The bottom end of the expansion inner tube 9 is vertically inserted into the inner side of the opening of the hose. A sealing ring 12 is snapped onto the outer side of the expansion inner tube 9. The sealing ring 12 is made of soft rubber material. When the expansion inner tube 9 is inserted into the inner side of the opening of the hose, the outer side of the sealing ring 12 will contact the inner side of the hose, forming a preliminary sealing effect to prevent liquid or gas from leaking from the gap between the hose and the expansion inner tube 9. The top connecting screw 5 is vertically inserted through the inner side of the top locking hole 4. A rotating top plate 6 is fixedly sleeved on the top of the top connecting screw 5 for convenient subsequent operation. A through locking hole 13 is provided at the top of the expansion inner tube 9, located at the center of the top of the expansion inner tube 9. The extended bottom end of the top connecting screw 5 is inserted into the inner side of the through locking hole 13. Simultaneously, a mating screw hole 14 is provided at the top of the extrusion inner block 10, which is locked to the inner side of the expansion inner tube 9. The bottom extension end of the top connecting screw 5 is threaded into the inner side of the mating screw hole 14. By rotating the top plate 6, the top connecting screw 5 rotates and moves downward within the mating screw hole 14, causing the extrusion inner block 10 to move downward within the expansion inner tube 9. Two rotating end blocks 3 are present, and the center of one end of each rotating end block 3 is fixedly sleeved at one end of the extrusion screw 7. By rotating the rotating end block 3, the extrusion screw 7 is driven to rotate in the screw hole on the outer side of the main sealing cover 1 and move inward. When the extrusion screw 7 moves inward, it will push the extrusion inner plate 8 to extrude the outer wall of the hose inward. At the same time, the extrusion inner block 10 moves downward and exerts downward pressure on the expansion inner tube 9, causing the expansion inner tube 9 to expand outward and further extrude the outer sealing ring 12, so that the sealing ring 12 fits more tightly against the inner wall of the hose, thereby achieving a stronger sealing effect and effectively preventing the leakage of substances inside the hose.
