[0025] In the specific implementation process, it is particularly worth noting that the staff fixes the empty box 6 to the top of the wall through the mounting holes on the two side connecting plates 16. The staff fixes the exhaust pipe 1 to the external pipe through the six mounting holes on the fixing plate 2. Then, the fan 3 is started, and the air inside the computer room enters the exhaust pipe 1 through the filter screen 5, starting to exhaust the computer room. After completion, just stop the fan 3. The filter screen 5 can filter dust. The staff rotates the handle 7, the handle 7 drives the worm 8 to rotate, the worm 8 drives the worm gear 9 to rotate, the worm gear 9 drives the gear 10 to rotate, the gear 10 drives the pin shaft to rotate, the gear 10 drives the racks 11 on the upper and lower sides to move relatively, the two racks 11 drive the columns 12 to move, the two columns 12 move in the empty box 6, and the two columns 12 drive the arc plates 13 to move. The two arc plates 13 contact the exhaust pipe 1 to realize the support of the exhaust pipe;

[0026] Furthermore, a first spring 14 is fixedly connected between each of the two columns 12 and the empty box 6. The material of the first spring 14 is carbon spring steel, and the elastic coefficient of the first spring 14 is selected according to actual needs as long as it meets the work requirements.

[0027] In the specific implementation process, it is particularly worth noting that the material of the first spring 14 is carbon spring steel, and the elastic coefficient of the first spring 14 is selected according to actual needs as long as it meets the work requirements. After the two columns 12 drive the arc plates 13 to contact the exhaust pipe 1, the two first springs 14 rebound, and further fix the arc plates 13 through the elastic force;

[0028] Furthermore, sliders 15 are fixedly connected to the outer walls of the two racks 11, and the outer walls of the two sliders 15 are slidably clamped to the inner wall of the empty box 6. When the two racks 11 move, the two racks 11 drive the sliders 15 to move, and the two sliders 15 slide in the chutes on the upper and lower sides of the inner wall of the empty box 6;

[0029] In the specific implementation process, it is particularly worth noting that when the two racks 11 move, the two racks 11 drive the sliders 15 to move, and the two sliders 15 slide in the chutes on the upper and lower sides of the inner wall of the empty box 6 to realize the guidance of the racks 11;

[0030] Specifically, first, the staff fixes the empty box 6 to the top of the wall through the mounting holes on the two side connecting plates 16. Then, the staff fixes the exhaust duct 1 to the external pipe through the six mounting holes on the fixing plate 2. After that, the staff rotates the handle 7.

The clamping column 19 is inserted into the inside of the filter screen frame 4 to fix the filter screen frame 4.

[0034] In the specific implementation process, it is particularly worth noting that the material of the second spring 18 is carbon spring steel. The elastic coefficient of the second spring 18 is selected according to actual needs as long as it meets the working requirements. When the filter screen frame 4 is inserted into the exhaust pipe 1, the outer wall of the filter screen frame 4 moves with the clamping post 19. The clamping post 19 first descends, driving the second spring 18 to compress. When the clamping post 19 moves to a position close to the filter screen 5, the second spring 18 rebounds and drives the clamping post 19 to move through the elastic force. The clamping post 19 inserts into the interior of the filter screen frame 4 to fix the filter screen frame 4, thus realizing the improvement of the firmness of the filter screen frame 4.

[0035] Specifically, the staff pulls the filter screen frame 4, and the filter screen frame 4 drives the filter screen 5 to move, removing the filter screen frame 4 from the exhaust pipe 1 to clean the filter screen 5. After the cleaning is completed, the staff reinserts the filter screen frame 4 into the interior of the exhaust pipe 1 to realize the cleaning of the filter screen 5. When the filter screen frame 4 is inserted into the exhaust pipe 1, the outer wall of the filter screen frame 4 moves with the clamping post 19. The clamping post 19 first descends, driving the second spring 18 to compress. When the clamping post 19 moves to a position close to the filter screen 5, the second spring 18 rebounds and drives the clamping post 19 to move through the elastic force. The clamping post 19 inserts into the interior of the filter screen frame 4 to fix the filter screen frame 4, thus realizing the improvement of the firmness of the filter screen frame 4.
