[0017] 2. The present invention provides a fixing mechanism, and when fixing the protection box, the protection box and the meter body are installed in suitable positions through the mounting plate. During the installation, the anti-slip plate will slide downward under the action of pressure, and the anti-slip plate will push the push rod to deflect when moving downward, and the push rod will push the slider to slide to one side during the deflection. At this time, the slider will squeeze the push plate when sliding, and the push plate will deflect after being squeezed, and the push plate will push the fixed plate to move when deflecting, so that the tooth block acts on one side of the installation position, so as to improve the stability of the installation of the mounting plate through the tooth block, thereby facilitating the protection of the meter body and preventing the protection box from loosening due to external force, thereby causing damage to the meter body.
