In the high-pressure buffering metal hose, the connector is directly connected with the steel pipe through the use of a slip, so that the high-pressure buffering metal hose becomes an integral whole, and when the high-pressure buffering metal hose is subjected to high-pressure impact, the bellows in the high-pressure buffering metal hose can play a telescopic expansion function. However, the outer reinforcing ring and the protective net limit the telescopic amount and the expansion amount, so that the buffering effect is good. The steel pipe connector welding position is prevented from being cracked and leaking due to high-pressure impact, and the conveying safety of the whole pipeline is well protected.

[0003] However, the above-mentioned scheme still has defects, because the elbow is not limited, which leads to the fact that the angle between the bellows, the steel band net and the elbow changes constantly, which leads to the fact that the connecting position of the bellows, the steel band net and the elbow is prone to breakage, reduces the service life of the bellows and the steel band net, and brings a poor use experience to the user.
