So design, make things convenient for the installation and the dismantlement of second joint 4.

In practical operation, the second joint 4 can be connected with other workpieces according to practical requirements, for example, the second joint 4 is connected with a water faucet, and the connection is not limited to this.

Referring to fig. 2, 4 and 5, when the water gun is connected to the first connector 3 and connected to the connector body 1, the first connecting portion 31 of the first connector 3 pushes the first core 21 to separate the sealing portion 221 of the second core 22 from the stopper 12, so as to conduct the flow channel 11, and allow water to flow into the water gun from the water pipe through the water pipe connecting end 42 of the second connector 4, the control core 2 and the water gun connecting end 32; when the water gun and the water gun connecting end 32 accidentally fall off or are not connected to the connector body 1, or the water pipe is accidentally opened, water flows into the flow channel 11 through the water pipe connecting end 42 of the second connector 4, and the water flow pushes the second core 22 to abut against the stop piece 12, so that the flow channel 11 is closed, and water leakage is prevented.

In another embodiment of the present invention, the second joint 4 may be fixedly provided to the joint main body 1 to be a part of the joint main body 1.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
