A plurality of mounting grooves 32 are provided on the inner wall of the connecting sleeve 31, and movable wedge blocks 33 are movably installed in the plurality of mounting grooves 32. A driving member that can drive the movable wedge blocks 33 to move is provided on the connecting sleeve 31. A sprinkler head 34 is fixedly installed at the lower end of the water supply branch pipe 3, and a top column 35 adapted to the water retaining assembly is fixedly installed inside the connecting sleeve 31.

[0033] The water retaining assembly includes a fixed inner cylinder 22, a compression spring 23 and a movable ball 24. The fixed inner cylinder 22 is fixedly installed in the plug-in tube 2. The lower end of the fixed inner cylinder 22 is smaller than the upper end. A convex ring is fixedly installed inside the plug-in tube 2. The compression spring 23 is fixedly installed on the convex ring. The movable ball 24 is fixedly installed at the end of the compression spring 23. The movable ball 24 fits with the inner wall of the fixed inner cylinder 22 under the elastic force of the compression spring 23. When the connecting sleeve 31 is sleeved on the outside of the plug-in tube 2, the top column 35 pushes the movable ball 24 upward, and the movable ball 24 is released from contact with the wall of the fixed inner cylinder 22.

[0034] The driving member includes two limiting rings 311, a movable ring 312, a plurality of first magnetic blocks 313, a plurality of second magnetic blocks 314 and a plurality of spring pieces 315. The two limiting rings 311 are fixedly mounted on the connecting sleeve 31. The movable ring 312 is sleeved on the connecting sleeve 31.
