[0002] Smoke alarms prevent fires by monitoring the concentration of smoke. They use ion smoke sensors inside. Ion smoke sensors are technologically advanced sensors that are stable and reliable. They are widely used in various fire alarm systems. They can automatically send out alarm signals during the smoke generation period when there is a fire hazard, and promptly remind people to put out the fire before a disaster occurs.

[0003] The existing smoke alarm lacks a convenient installation mechanism that is conducive to installation and disassembly during actual use. When the smoke alarm is actually installed and disassembled, its operation is generally not convenient. Before installing the smoke alarm, a positioning plate needs to be installed first. The positioning plate will be fixed with screws during installation, and workers need to drill holes. However, the holes are usually drilled by workers after visual inspection. There may be a certain deviation between the position of the hole and the position of the installation hole on the smoke alarm, which will affect the subsequent installation. Utility Model Content
