When the sprinkler is in use, the rotating rod 23 can be tightly attached to the chute 24 under the impact of the water flow, and the water flow will not impact the sprinkler 2 and cause it to separate.

[0032] According to some embodiments of the present invention, the connecting rod 21 is optionally provided with an inclined groove 25 at a position corresponding to the rotating rod 23. This facilitates the inward contraction of the rotating rod 23 so that it can be inserted into the chute 24 during removal, and also facilitates removal without getting stuck in the chute 24 and being difficult to remove. Only under the impact of water flow can the rotating rod 23 rotate and tightly adhere to the chute 24 to ensure the connectivity of the sprinkler 2.

[0033] According to some embodiments of the present invention, optionally, a non-slip pad 26 is provided on the top of the rotating rod 23 and the side opposite to the slide 24. In order to ensure its good connection and prevent it from falling during use.

[0034] According to some embodiments of the present invention, an iron sheet 15 is optionally provided in the groove 12 and a magnetic sheet 27 is provided on the top of the connecting rod 21. In order to ensure the connectivity between the sprinkler 2 and the nozzle body 1, the sprinkler 2 and the nozzle body 1 are not easily separated and are not easily detached during use.
