When connecting the fire hose, a layer of soft protective material must be padded when the hose interface is put on, and then tightened with galvanized iron wire or a hose clamp. Most of the current fire hose connections are tightened with galvanized iron wire or a hose clamp, which makes the connection not fast enough, the fire hose cannot be extended quickly, and the fire cannot be extinguished in time, which affects the speed of firefighting and is inconvenient for users.
