When the moving part 32 reciprocally moves relative to the connecting part 31 to approach the supporting part 21, the area of the air outlet part 22 that can be increased by the wind shielding structure 3 can be increased. By controlling the movement of the moving part 32 relative to the connecting part 31, the distance between the wind shielding structure 3 and the supporting part 21 can be quickly adjusted to change the air cooling distance, which is also conducive to improving the versatility of the cooling device.
