[0048] The existing method for fixing the fire extinguisher to the ceiling is to directly fix the fire extinguisher as a whole on the ceiling through a fixing frame. During the process of fixing the fire extinguisher to the fixing frame, the fire extinguisher is prone to shaking, which makes the fixing process laborious.

[0049] Based on the above problems, the following embodiments are proposed.

[0050] Embodiment 1:
