[0002] The flame identification device is a flame detector, also known as a photosensitive fire detector. It is used to respond to the optical characteristics of fire, that is, to detect the light intensity of the burning flame and the flickering frequency of the flame. After detecting a fire, it will sound an alarm to remind people.

[0003] When installing a flame detector, in order to avoid detection blind spots, it is generally installed in a corner so that all locations in the house are within the detection range. During installation, the flame detector is usually fixed to the wall by bolts, but the bolt connection will make the disassembly and assembly of the flame detector more time-consuming, and then when the flame detector is subsequently disassembled and maintained, it will take a long time to disassemble and assemble the flame detector, thereby reducing the maintenance efficiency of the flame detector.
