When using, by inserting insertion pipe 2 into main pipe 1, main pipe 1 can open the sealing assembly inside main pipe 1 to control the conduction, so that main water inlet channel 16 and main water outlet channel 17 are communicated, the device is in the open state, so as to facilitate the flow and discharge of water, by loosening and taking out insertion pipe 2, using elasticity and combining with the principle of acting force and reaction force, sealing assembly returns to the initial position, and the communication of main water inlet channel 16 and main water outlet channel 17 is blocked, the device is in the closed state, so as to automatically close the water outlet of the device, the operation is simple, convenient and practical, and the drainage can be quickly controlled.
