[0013] 1. The display screen protection plate is provided with a knob, a main bevel gear, a slave bevel gear, a bidirectional screw, a nut seat and a limit rod. The main bevel gear is driven to rotate by turning the knob, and then the slave bevel gear and the bidirectional screw are driven to rotate. The rotating bidirectional screw cooperates with the thread of the nut seat to displace the nut seat and the limit rod. When one end of the limit rod is inserted into the upper limit groove of the shell, it can be snapped, and then the protection plate is quickly limited, replacing the traditional bolt connection method. When the protection plate is limited or released, the user only needs to turn the knob by hand, and there is no need to use tools to screw multiple bolts, which is highly efficient.
