[0020] Fixed grooves 12 are symmetrically fixedly installed on both sides of the air intake pipe 5, and a slide plate 19 is arranged inside the fixed groove 12. Slide blocks 20 are fixedly installed on the top and bottom of the slide plate 19, and the slide block 20 is slidably connected to the fixed groove 12. A connecting rod 13 is fixedly installed on one side of the slide plate 19, and one end of the connecting rod 13 passes through the fixed groove 12, and a pull plate 14 is fixedly installed on one end of the connecting rod 13. A second spring 18 is fixedly installed on one side of the slide plate 19 and located on the outside of the connecting rod 13, and one end of the second spring 18 is fixedly connected to one side of the fixed groove 12. A plug rod 16 is fixedly installed on one side of the pull plate 14, and the plug rod 16 is inserted into the interior of the cover 6 and the air intake pipe 5 at the same time.

[0023] The working principle of the utility model is:

[0024] When the utility model is used, the fixing plate 1 is fixed to the wall by the fixing bolts 3, and then the plug block 9 on the top of the smoke alarm body 2 is inserted into the inside of the socket 8. When inserting, the limit block 11 is pressed against the inner wall of the socket 8, and the first spring 10 is compressed. When the top of the plug block 9 abuts against the bottom of the fixing plate 1, the limit block 11 passes through the socket 8 under the action of the reset first spring 10. At this time, the smoke alarm body 2 is fixed under the fixing plate 1. When it is necessary to disassemble it, the two limit blocks 11 are pressed close to each other, and the two limit blocks 11 are stored in the inside of the installation groove 7.
