The working process of the utility model is: the water receiving pipe 5 is connected with the water source through the threaded section 51 . When the water intake pipe 1 is not inserted into the middle connector 2, the spring 8 lifts the support frame 7, so that the water intake sealing ring 6 is pressed against the lower end surface 333 of the rear connector 3, that is, the connection between the water intake sealing ring 6 and the rear connector 3 The lower end surface 333 constitutes a sealing pair, which cuts off the water channel so that water cannot enter the middle connector 2 . When it is necessary to take water from the water source, insert the water intake pipe 1 into the middle connector 2, and rotate the water intake pipe 1 downward at the same time, so that the screw-in surface 132 on the water intake pipe 1 rotates around the screw-in protrusion 25 of the middle connector 2 Simultaneously, push out the support frame 7 downwards; when screwing in a certain distance, the screw-in protrusion 25 of the middle connector 2 falls into the fixed surface 133 of the water intake pipe 1, so that the water intake pipe 1 is automatically fixed. Now, because the support frame 7 is jacked up downwards, it drives the water intake sealing ring 6 to move downward, and the water flow flows into the water intake pipe through the gap on the limit cylindrical surface of the support frame 7 and the water intake 20 on the water intake pipe 1 . As shown in Figure 12, the arrows in the figure indicate the direction of the water flow channel. the
