[0034] Working principle: When installing a fire sprinkler, first insert the sleeve 23 into the connecting rod 2 from the end away from the limit block 22, so that the limit block 22 is inserted into the sliding groove 24, and the connecting rod 2 is installed on the first screw hole 21 through threads, and then the threaded tube 11 is aligned with the water pipe. At this time, the rotating rod 28 is rotated around the rotating block 27 and the direction is kept parallel to the fire sprinkler, and the sleeve 23 is moved so that the limit block 22 slides on the sliding groove 24 and finally abuts against its surface to increase the lever arm, so that the rotating rod 28 and the connecting rod 2 and the sleeve 23 form an L shape, and then the rotating rod 28 is rotated around the fire sprinkler to complete the connection of the fire sprinkler.

[0035] When the glass body 13 is broken and the fire sprinkler head needs to be replaced, first remove the fastening screw 35 from the connecting tube 3 through the thread, and pull the connecting tube 3 out of the plug-in tube 31, then insert the connecting tube 3 with the intact glass body 13 installed into the plug-in tube 31, and align the second screw hole 32 and the plug-in hole 33 by rotating the threaded tube 11. At this time, insert the fastening screw 35 into the plug-in hole 33 and connect it to the second screw hole 32 through the thread, and finally abut against the surface of the mounting groove 34, thereby completing the replacement of the fire sprinkler head.
