Monitoring apparatus

Abstract

A monitoring apparatus includes a main body, a mounting plate, and a fixing plate. The mounting plate is connected to the main body and has a first bending rib structure protrusively formed thereon. The fixing plate is fixed to a mounting target and is disposed opposite to the mounting plate. The fixing plate has a first opening structure formed thereon corresponding to the first bending rib structure and a second bending rib structure laterally extending from the first opening structure. When the mounting plate is connected to the fixing plate to make the first bending rib structure pass through the first opening structure, the first bending rib structure rotates with rotation of the mounting plate relative to the fixing plate to be engaged with the second bending rib structure, so as to fix the mounting plate to the fixing plate.
