[0041] Working principle: When using a hand-held cutting machine for cutting operations, start the fan 5, and let the fan 5 suck the dust generated during cutting into the interior of the sedimentation chamber 4 through the dust suction pipe 3. The dust will be blocked by the filter cloth 6 and then settle into the interior of the collection box 16. After a period of use, dust will accumulate on the surface of the filter cloth 6. At this time, hold the pulling plate 8 and lift the pulling plate 8, which will drive the pulling rod 7, and then drive the placement plate 9 to rise. The pushing spring 15 will also push the limiting plate 12, thus pushing the cleaning plate 11 to closely fit the surface of the filter cloth 6. When the placement plate 9 moves up and down, the dust accumulated on the surface of the filter cloth 6 will be cleaned. The cleaned dust will settle into the interior of the collection box 16. By allowing the pushing spring 15 to push the limiting plate 12 when the placement plate 9 is driven to move up and down, the cleaning plate 11 is pushed to closely fit the surface of the filter cloth 6, which can clean the dust accumulated on the surface of the filter cloth 6, ensure the air circulation, and ensure the dust suction efficiency of the fan 5, enabling the cutting machine to maintain high efficiency when collecting and processing dust. When too much dust accumulates in the collection box 16, pull the pull ring 23 by hand, which will drive the fixed plate 20 and make the fixed column 21 leave the interior of the card slot 17. At this time, the collection box 16 can be taken out from the interior of the sedimentation chamber 4. After cleaning the dust in the collection box 16, insert the collection box 16 back into the interior of the sedimentation chamber 4. Then release the hand pulling the pull ring 23, and the pulling spring 22 will pull the fixed plate 20 to reset the fixed plate 20 and make the fixed column 21 engage with the card slot 17 again to fix the collection box 16. By allowing the fixed plate 20 to drive the fixed column 21 to engage and disengage with the card slot 17, the collection box 16 can be quickly disassembled and installed, making the cleaning process of the collection box 16 more convenient and improving the cleaning efficiency of the collection box 16.
