[0031] A latching seat 11 is fixedly connected to the outer surface of the smoke sensor 1. A fixing bracket 12 is fixedly connected to the side surface of the latching seat 11. A sliding rod 13 is fixedly connected to the inner surface of the fixing bracket 12. A spring 14 is provided on the outer surface of the sliding rod 13. A connecting bracket 15 is slidably connected to the outer surface of the sliding rod 13. A pin rod 16 is fixedly connected to the inner surface of the connecting bracket 15. A handle 17 is fixedly connected to the outer surface of the connecting bracket 15. A positioning groove 18 is provided on the upper surface of the latching seat 11. The inner surface of the positioning groove 18 is adapted to the latching block 9. The inner surface of the pin hole 20 is adapted to the pin rod 16. The outer surface of the buckle seat 11 is provided with an arc-shaped through hole 21. The inner surface of the arc-shaped through hole 21 is adapted to the arc-shaped insert 8. There are two buckle seats 11 and they are symmetrically distributed. The outer surface of the connecting frame 15 is slidably connected to the fixing frame 12.

[0032] Working principle: When it is necessary to inspect the internal components 2 of the smoke sensor 1, simply pull down the handle 17 to drive the connecting bracket 15 to slide down along the slide rod 13, compressing the spring 14. This will cause the pin rod 16 to disengage from the pin hole 20, thereby releasing the restriction on the flip base 7. Then, flip the flip base 7 around the fixed post 6 to drive the arc-shaped insert 8 to disengage from the arc-shaped insert hole 19 and the arc-shaped through hole 21, thus releasing the restriction on the smoke sensor 1. Finally, pull down the smoke sensor 1 to complete the disassembly of the smoke sensor 1, thereby allowing the internal components 2 of the smoke sensor 1 to be inspected. The smoke sensor 1 is exposed for easy maintenance. When it needs to be installed, first align the snap block 9 with the positioning slot 18 and insert it to quickly position the smoke sensor 1, thereby improving the installation speed. Then, pull the handle 17 again and rotate the flip base 7 around the fixing post 6 so that the arc-shaped plug 8 is inserted into the arc-shaped plug hole 19 through the arc-shaped through hole 21. When the plug hole 20 on the flip base 7 corresponds to the plug rod 16, release the handle 17. Under the restoring force of the spring 14, the plug rod 16 will automatically snap into the plug hole 20, thus completing the installation of the smoke sensor 1. It is simple, convenient and does not require tools.
