At this time, the user drives the connecting plate 10 connected to the positioning shell 4 to rotate through the positioning plate 3. While the positioning shell 4 rotates, the toothed plate 5 connected to the inner cavity of the positioning shell 4 drives the transmission gear set 7 to rotate counterclockwise. While the transmission gear set 7 rotates, it drives the gear ring 8 to rotate clockwise. The gear ring 8 rotates clockwise. The transmission shell 9 drives the connecting plate 10 connected to it to rotate clockwise, and the clockwise rotating connecting plate 10 drives the ventilation shell 15 and the structure connected to it to move in a circle. When the user drives the sun visor 14 to move to the specified position, the user drives the connecting rod 12 into the inner cavity of the limiting shell 11 through the first fixed plate 13, and drives the two sun visors 14 closer. At the same time, the user starts the fan 16, and the fan 16 blows the air cooled by the cooling plate 17 out of the ventilation shell 15, thereby completing the heat dissipation for the staff after high-intensity work.
