A plurality of end holes 5 are provided on the upper end face of the protective shell 4, and a plurality of side holes 6 are provided on the side of the protective shell 4; the end holes 5 are circular, and the side holes 6 are vertical bar-shaped; the end holes 5 and side holes 6 opened on the protective shell 4 allow air to smoothly enter the protective shell 4, so that the protective shell 4 will not affect the smoke detection module 10's perception of smoke while providing protection.

[0027] One side of the protective shell 4 is also provided with an avoidance opening 3 for avoiding the data plug connector 2, and the avoidance opening 3 is rectangular in shape; the set avoidance opening 3 can be used to avoid the data plug connector 2 to prevent the protective shell 4 from affecting the data plug connector 2.

[0028] A plug hole 19 is provided in the middle of the connecting plate 11, and a lock ring 18 is fixedly connected to the middle of the upper end surface of the connecting plate 11. The lock ring 18 is concentric with the plug hole 19, and the interior of the mounting plate 1 is provided with a locking component for cooperating with the plug hole 19 to fix the connecting plate 11; the locking component includes two connecting grooves 14, and the two connecting grooves 14 are respectively opened at positions on both sides of the upper end surface of the mounting plate 1, and the connecting grooves 14 are slidably connected with the inner slide 16 of the groove, and the upper end of the inner slide 16 is fixedly connected with the arc-shaped locking block 12 that cooperates with the plug hole 19, and the opposite side of the two inner slides 16 is fixedly connected with the sliding plate 8, and the sliding plate 8 is slidably connected to the mounting plate 1, and the connecting grooves 14 are respectively opened at positions on both sides of the upper end surface of the mounting plate 1. A spring 15 is installed in the cavity of the slide plate 16 in the groove away from the sliding plate 8; the curvature of the curved edge of the arc-shaped locking block 12 fits with the curvature of the inner wall of the locking ring 18. When the connecting plate 11 needs to be fixed, first press the sliding plate 8 to make the two slide plates 16 in the groove and the arc-shaped locking block 12 close to each other, and then insert the two arc-shaped locking blocks 12 into the plug-in hole 19. After insertion, release the sliding plate 8, and the arc-shaped locking block 12 is reset under the action of the spring 15, so that the curved surface of the arc-shaped locking block 12 fits the inner wall of the locking ring 18, and the locking is completed by using the step formed by the locking ring 18 and the plug-in hole 19.
