In fact, the blocking member 1 may be a member that is not bent by the locking band 211, as long as it can reliably block the leakage position.

The plugging component 1 can be provided with a pressure relief structure for reducing the pressure of high-pressure fluid leaked from the leakage position of the pipeline A to be repaired, and further, the plugging component 1 can be ensured to be capable of plugging the leakage position quickly and efficiently. Here, the embodiment of the present invention does not limit the specific structural form of the pressure relief structure, as long as the corresponding pressure relief effect can be achieved.
