[0029] Working principle: The electrical components appearing in this application are externally connected to a power source and a control switch during use. After the present utility model is installed, first check the installation and fixation as well as the safety protection of the present utility model, and then it can be used; during use, the dust-proof component 4 and the connecting ring body 3 are sleeved outside the fire detector 1. Align the first convex block 10 with the second convex block 11, and insert each L-shaped clamping block 7 into the corresponding L-shaped clamping groove 5 respectively. The user pulls the rotary knob 14 outwards to slide the connecting shaft 17 outwards, and the insertion block 25 disengages from the insertion slot 24. Then the user rotates the rotary knob 14 to drive the connecting shaft 17 to rotate. Through the cooperation of the spline groove 18 and the spline block 19, the rotating shaft 13 and the gear 12 are driven to rotate. The gear 12 meshes with the toothed ring block 6 to rotate, the toothed ring block 6 drives the arc-shaped groove 8 to rotate, and the arc-shaped groove 8 drives the inner slider 9 and the L-shaped clamping block 7 to move, so that the L-shaped clamping block 7 is completely inserted into the L-shaped clamping groove 5, thereby completing the installation and fixation of the installation ring body 2 and the connecting ring body 3.

[0030] When the dust-proof component 4 is impacted by dust, the top block 45 moves inwards, causing the circular ring shell 44 to drive the annular slider 43 to slide in the annular groove 42, thereby driving the inner sliding plate 153 to slide and stretching the second spring 154, facilitating the subsequent rebound of the second spring 154, and enabling the dust-proof net cover 46 to return to its original position, providing sufficient protection for the fire detector 1.
