A pull rod 405 is fixed on one side, and the movable block 404 is driven to move by the pull rod 405. A clamping rod 406 is fixed on the opposite side of the front and rear movable blocks 404. The dustproof mechanism 4 also includes a filter screen 410 attached to the lower surface of the shell 308, which is used to filter dust and prevent dust from entering the interior of the shell 308. Four plug rods 408 are fixed on the upper surface of the filter screen 410, and a clamping groove 407 is provided on the opposite side of the front and rear plug rods 408. The dustproof mechanism 4 also includes four slots 409 opened on the lower surface of the shell 308.

[0030] Among them, the insertion rod 408 is slidably connected to the inside of the slot 409 to limit the filter 410, the clamping rod 406 is slidably connected to the inside of the clamping slot 407 to install and fix the filter 410, and sliding holes are opened on the opposite sides of the left and right bin bodies 401. The pull rod 405 is slidably connected to the inside of the sliding hole, and the movable block 404 is conveniently pulled to move through the pull rod 405.

[0031] In addition, the opposite sides of the front and rear springs 403 are respectively fixed to the opposite sides of the two movable blocks 404, and the opposite sides of the front and rear springs 403 are respectively fixed to the opposite sides of the inner cavities of the front and rear bins 401.

[0034] The working principle of the above embodiment is:

[0035] (1) When the position of the fan 309 needs to be adjusted, the motor 301 is started. The motor 301 drives the first rotating rod 302 to rotate, and the first rotating rod 302 drives the turntable 306 and the second rotating rod 304 to rotate together. The second rotating rod 304 rotates to drive the fixing frame 305 to move. The fixing frame 305 drives the T-shaped block to move through the connecting rod 307. The T-shaped block slides inside the T-shaped groove to limit the fixing frame 305 from making an upward and downward linear movement. The fixing frame 305 drives the shell 308 to move through the connecting rod 307. The shell 308 drives the T-shaped rod to move in the sliding hole to increase the stability of the shell 308 when moving. The fan 309 is driven to move together through the shell 308 to change the position of the fan 309, so that the fan 309 can blow air to dissipate heat for objects at different heights and improve the heat dissipation effect.

[0036] (2) When the filter 410 needs to be installed, the two pull rods 405 are pulled at the same time. The pull rods 405 drive the movable block 404 to move and squeeze the spring 403 and the telescopic rod 402. When the movable block 404 moves, it drives the clamping rod 406 to move together. At this time, the insertion rod 408 is inserted into the inside of the slot 409, and the pull rod 405 is released. The movable block 404 is reset under the elastic action of the spring 403, driving the clamping rod 406 to move, so that the clamping rod 406 is clamped into the inside of the clamping slot 407, and the filter 410 is installed and fixed, which is convenient for the use of the filter 410.
