[0033] The implementation principle of an aspirating smoke detector that is easy to install in this application is:

[0034] First, when fixing the mounting plate 5 on the wall, the mounting plate 5 is pushed horizontally. At this time, the mounting tube 7 on one side of the mounting plate 5 is displaced into the hole reserved in the wall. At this time, the "L"-shaped block 9 inside the mounting tube 7 is convenient for displacement through the inclined surface when displacing into the hole reserved in the wall. However, when pulling out the mounting tube 7, the No. 1 rotating block 12 inside the No. 2 "U"-shaped fixing block 11 is connected to the No. 2 rotating block 13 inside the No. 1 "U"-shaped fixing block 10 through the spring 16. At this time, the spring 16 is convenient for changing the angle during squeezing. At this time, the "L"-shaped block 9 is squeezed by the spring 16 and is rotated and engaged on the inner wall of the wall through the connecting shaft 8 to complete the fixation.

[0035] Secondly, when fixing the detector body 1 on the mounting plate 5, the mounting plate 5 is rotated to the inside of the arc-shaped limit groove 2 through the arc-shaped limit groove 2 on one side of the detector body 1. At this time, the mounting plate 5 is limited by the limit baffle 3 inside the arc-shaped limit groove 2, and can be rotated to the optimal installation angle.

[0036] Finally, by passing the connecting fixing plate 6 through the holes reserved in the positioning block 4 and the installation hanging plate 5, the connection work can be performed to provide stability after installation.
