[0013] (1) Through the designed motor, reciprocating screw, inner block, driving block and driving frame, the driving frame is placed on the front and back sides of the main body of the LED display screen. The motor drives the reciprocating screw to rotate. The reciprocating screw and the inner block cooperate to make the driving block reciprocate on the reciprocating screw, thereby driving the driving frame to reciprocate outside the display screen to drive away birds, effectively preventing birds from staying on the display screen and producing feces, thereby damaging the display screen and blocking the display. Through the designed transparent plate, the surface of the driving frame is transparent to avoid blocking the display screen. Through the designed connecting assembly and end frame, one end of the reciprocating screw is rotatably connected to the end frame through the connecting assembly, and supported by the end frame to prevent one end of the reciprocating screw from being suspended in the air and easily tilted to affect the drive. Through the designed guide rod and guide hole, the reciprocating movement of the driving block is guided and supported. BRIEF DESCRIPTION OF THE DRAWINGS
