Using the first bolt 17, which mates with the threaded hole in the dust collector, the mounting ring 16 can be fixed in the appropriate position. Then, by simultaneously pulling the two handles 14 with both hands, the two support plates 13 move simultaneously, thereby moving the two sliding plates 6 outside the horizontal plate 5. During this movement, the moving rod 901 moves inside the cylinder 10, compressing the support spring 903 in conjunction with the circular plate 902. At this time, the limiting block 7 moves horizontally. Then, in conjunction with the positioning plate 15 and the positioning groove, the limiting block 7 and the positioning groove are easily aligned. Slide the limit switch, then release the two pull handles 14. Under the support and rebound of the support spring 903, the two limit blocks 7 and the limit grooves 11 at the support block 8 are interlocked and limited, which can effectively ensure that the limit blocks 7 and the limit grooves 11 are effectively limited, thereby effectively limiting the bottom of the round tube 2 and the filter bag body 1. This can stably fix the bottom of the filter bag body 1, preventing shaking during operation due to the lack of a fixing device at the bottom. The bottom of the filter bag body 1 no longer frequently rubs against the inside of the dust collector, thus effectively preventing the filter bag body 1 from being damaged and significantly improving its durability. Finally, the top of the filter bag body 1 can be installed by using the second bolt 1202 in conjunction with the threaded hole set on the top of the dust collector.
