[0031] A hose connector 5 is welded to the surface of the connector 4, and a spring 2 is welded to the surface of the ferrule 3.

[0032] When it is necessary to install the lining core 14;

[0033] First, the hydraulic brake hose 1 is driven by an external force to move into the first hole 9. Subsequently, the connector 4 is driven by an external force to move. The movement of the connector 4 drives the thread groove 12 to move to the surface of the external thread ring 6 and be connected to the external thread ring 6. At the same time, the two second slots 13 move to communicate with the corresponding first slots 8. Subsequently, the lining core 14 is driven by an external force to move. The movement of the lining core 14 drives the two clamping strips 15 to move. The two clamping strips 15 respectively move and are clamped inside the corresponding second slots 13. Subsequently, the two clamping strips 15 continue to move into the first slots 8. Finally, it shows that the lining core 14 is disposed inside the hydraulic brake hose 1, and the two clamping strips 15 on the lining core 14 are respectively in contact with the corresponding first slots 8 and second slots 13.

[0035] Working principle:

[0036] When the liner core 14 needs to be installed;

[0037] First, the hydraulic brake hose 1 is driven by an external force to move into the interior of the hole one 9. Subsequently, the connector 4 is driven by an external force to move. The connector 4 drives the threaded groove 12 to move to the surface of the external thread ring 6 and connect with the external thread ring 6. At the same time, the two card slots two 13 move to communicate with the corresponding card slots one 8. Subsequently, the liner core 14 is driven by an external force to move. The liner core 14 drives the two card strips 15 to move. The two card strips 15 respectively move and are stuck in the interiors of the corresponding card slots two 13. Subsequently, the two card strips 15 continue to move into the interiors of the card slots one 8.
