[0032] Specifically, when the protective cover 10 is installed, the mounting rod 12 and the mounting seat 13 are installed and positioned together. After the initial installation, the mounting rod 12 is rotated, and the mounting rod 12 drives the bottom limit rod 14 and the limit plate 15 to rotate. The limit plate 15 is rotated to the side of the limit block 16 to achieve tight installation.

The dust cover 24 filters the air entering the fan 20. When used for a long time, if the fan 20 fails, the positioning ring 23 is rotated, and the positioning ring 23 and the positioning rod 21 are threaded together.
