The invention discloses an anti-power-off monitoring device, comprising a bottom plate, wherein a battery is installed in the middle of the upper end of the bottom plate, electrode columns are connected to the left and right sides of the upper end of the battery, a movable plate that is installed at the left end of the battery includes a plate, a blind hole and a heat dissipation hole, a screw isfixedly connected to the left end of the movable plate, a stopper is connected to the left end of the screw, an adjustment plate is mounted on the left side of the movable plate, first circular holesare respectively opened on the upper, middle and lower ends of the adjustment plate, and a rubber ring is mounted on the right end of the adjusting plate. Due to the structure provided with a first spring, a second spring, a buffer plate and an elastic rubber rod, the anti-power-off monitoring device is capable of reducing the impact of external force on the battery, and avoiding the phenomenon that the battery is damaged after the external force hits the battery, which leads to the spontaneous combustion of the battery.
