The two sides of the lower support plate 12 are fixedly connected to the L-shaped brackets 111 on both sides of the upper support plate 11 by screws so that a space for installing the sprinkler 20 is formed between the two.

[0024] In this embodiment, if Figure 1 and Figure 2 As shown, the sprinkler 20 is movably limited and installed in the mounting frame 10. The bottom 21 of the sprinkler 20 is placed on the lower support plate 12 and is provided with a nozzle head 22 that penetrates to the bottom of the lower support plate 12. The bottom 21 is preferably a spherical structure. The nozzle head 22 is provided with a spray hole. The lower support plate 12 is correspondingly provided with a through hole for the nozzle head 22 to pass through. Preferably, the lower support plate 12 is structured with a concave cavity 121 for accommodating the bottom 21 of the sprinkler 20, so that the bottom of the sprinkler 20 can be limited.
