Use a tool to toggle the four clamping blocks 33 through the through grooves opened on the two fixing plates 26, so that each inner rod 32 retracts into the corresponding outer cylinder 31. Then the clamping block 33 will be separated from the corresponding clamping groove 37, and then the dust collection net 35 will be separated from the fixing plate 26, so as to remove the dust collection net 35 to clean the intercepted dust. Then, similarly, by corresponding the cleaned dust collection net 35 with the fixing plate 26, and through the outward expansion of the outward expansion spring 34, the clamping block 33 is re-engaged with the clamping groove 37 to complete the installation of the dust collection net 35 and the fixing plate 26. Then, similarly, the driving source 7 is used to drive the connecting rod 21 to reverse compared with before, so as to drive the two adjusting lead screws 24 to reverse compared with before, and then drive the fixing plate 26 and the dust collection net 35 to be translated back into the air inlet pipe 5.
