The working principle of the utility model is as follows: firstly, the locking lugs 205 of the four groups of fixing components are all adjusted to be attached to the surfaces of the corresponding limiting plates 209, so that the positions of the locking lugs 205 relative to the limiting plates 209 are in a horizontal closed state (initial state), the embedded mounting plates 20 and the fixing components are integrally placed into the embedded boxes of the ceilings manually, and then the fixing bolts 206 are screwed clockwise manually through screwing tools;

the fixed bolt 206 drives the swivel and the fastening nut 207 which are in threaded connection with the fixed bolt to rotate simultaneously in the clockwise rotating process, the locking hanging lug 205 is driven to rotate along with the swivel to rotate simultaneously, and when the swivel rotates by a certain angle to enable the limiting block 2051 to be attached to the surface of the limiting plate 209, the locking hanging lug 205 is changed from an original horizontal closed state to a vertical open state (the clamping working state);

then, the fixing bolt 206 is manually screwed by the screwing tool continuously to rotate clockwise, during the clockwise rotation of the fixing bolt 206, the swivel moves downwards along the thread of the fixing bolt 206, so that the locking hanging lugs 205 move downwards along with the swivel, the fastening nuts 207 also move downwards along with the swivel and the locking hanging lugs 205, and the A surface of the fastening nuts 207 is kept in limit fixation through the B surface of the locking hanging lugs 205, so that the movement of the fastening nuts 207 in the circumferential direction is limited;

when the locking hanging lugs 205 move a certain distance and then are attached to the surface of the embedded box, the locking hanging lugs 205 and the embedded mounting plate 20 clamp the embedded box, the fixing bolts 206 are continuously screwed to enable the locking hanging lugs 205 and the embedded mounting plate 20 to clamp the embedded box completely, the locking hanging lugs 205 are fixed through the fastening nuts 207, the fact that internal threads of the rotating ring are cracked due to the fact that the rotating ring is easy to age after the rotating ring is used for a long time can be prevented through the fastening nuts 207, the locking hanging lugs 205 cannot clamp the embedded box, namely the cracked rotating ring cannot be continuously in threaded connection with the fixing bolts 206, the clamping force of the locking hanging lugs 205 to the embedded box is weakened, loosening occurs, the phenomenon that the embedded box falls occurs is caused, the fact that the rotating ring is limited through the fastening nuts 207 is not moved along the fixing bolts 206, and the clamping of the locking hanging lugs 205 to the embedded box is maintained.

After the embedded mounting plate 20 and the embedded box are fixed, the indication board 30 is manually inserted into the placing groove 107 of the movable mounting frame 103, so that the hanging strip 301 of the indication board 30 is attached to the inner bottom surface of the movable mounting frame 103, and then the manual cover plate 10 is sleeved and clamped on the periphery of the embedded mounting plate 20, so that the cover plate 10 is fixedly connected with the embedded mounting plate 20, and the emergency evacuation indication board 30 is mounted.

When an emergency occurs, the smoke alarm is started, the circuit board 70 controls the small-sized electric lock 801 to be powered off when the smoke alarm is started, so that the lock rod 802 of the small-sized electric lock 801 is retracted, the fixation of the movable mounting frame 103 is released, the movable mounting frame 103 slides downwards along the inner wall surface of the accommodating shell 101, the shielding of the air outlet hole 102 is released by the baffle 106, the movable mounting frame 103 slides downwards, the indication board 30 also moves downwards, a certain distance can be formed between the indication board and a ceiling, shielding of the indication board 30 after smoke gathering of the ceiling is reduced, the air supply unit (not shown in the drawing) externally supplies air to the ventilation pipe 202 when the smoke alarm is started, so that air flows into the accommodating shell 101 through the ventilation pipe 202, and the air flows obliquely out through the inclined air outlet hole 102 arranged in the accommodating shell 101, so that the air flow is further ensured not to be shielded when the smoke rises to the ceiling, and the smoke is blown away through the air flow.
