[0006] Second fire-fighting connectors are arranged on the two sides of the end of the pipe body close to the first fire-fighting connector in the radial direction;

[0007] Second tightening devices are installed on the second fire-fighting connectors;

[0008] A first cover is arranged at the end of the inner cavity of the first tightening device close to the first fire-fighting connector, and is used for plugging the first fire-fighting connector;

[0009] A second cover is arranged at the end of the inner cavity of the second tightening device close to the second fire-fighting connector, and is used for plugging the second fire-fighting connector.

[0010] Further, a first clamping ring is arranged on the inner wall of the first tightening device, and a first clamping groove matched with the first clamping ring is arranged on the first cover;

[0011] A first sliding channel is arranged on the inner wall of the first fire-fighting connector.

[0012] Further, a first sealing ring is arranged between the first fire-fighting connector and the first tightening device, and is used for sealing the connection between the first fire-fighting connector and the first tightening device.

[0013] Further, a second clamping ring is arranged on the inner wall of the second tightening device, and a second clamping groove matched with the second clamping ring is arranged on the second cover;

[0014] The inner wall of the second fire-fighting connector is provided with a second sliding groove.

[0015] Further, a second sealing ring is arranged between the second fire-fighting connector and the second tightening device to seal the joint between the second fire-fighting connector and the second tightening device.

[0016] Further, the first fire-fighting connector and the first tightening device are connected through a buckle;

[0017] The second fire-fighting connector and the second tightening device are connected through a buckle.

[0018] Compared with the prior art, the fire-fighting connector has the advantages that: the fire-fighting connector is arranged at one axial end and two radial sides of the pipe body, which makes up for the vacancy that the water suction operation cannot be completed due to poor parking position of the fire truck, and has good water suction effect and good water supply effect for fire fighting.
