The first connecting rod drives the connecting seat to move through the second rotating shaft. The connecting seat drives the second connecting rod to move. Since the second connecting rod is fixedly connected to the rotating ring, and the rotating ring is sleeved on the surface of the third connecting rod, the second connecting rod will rotate around the surface of the third connecting rod through the rotating ring. At the same time, the second connecting rod will drive the arc-shaped tightening block to move, so that the arc-shaped tightening block presses against the filter bag, so that the filter bag contacts the surface of the mounting plate, thereby realizing the limiting fixation of the overall structure.

[0021] 6. The present invention provides a flexible vibration structure, which can be screwed into the interior of the second connecting rod through the third screw. The second screw sleeve cooperates with the third screw thread. Since the second screw sleeve is fixedly connected to the counterweight block, the fixed connection of the entire structure is convenient.

[0022] 7. The present invention provides a power-assisting rod and a limiting ring.

[0044] The flexible vibration structure 10 includes a third screw 101, the threaded end of the third screw 101 passes through the second connecting rod 93 and extends to the bottom of the second connecting rod 93, the bottom of the surface of the third screw 101 is threadedly connected to the second screw sleeve 102, and the bottom of the second screw sleeve 102 is fixedly connected to the counterweight block 103.

When the third screw 101 and the second screw sleeve 102 are disengaged, the spring 13 will flexibly connect the second connecting rod 93 and the second screw sleeve 102. Therefore, when air passes through the counterweight 103, the counterweight 103 will drive the second screw sleeve 102 and the spring 13 to shake slightly. Through the shaking of the counterweight 103, the dust on the surface of the filter bag 2 can be removed.

[0047] Working principle: When the user needs to replace the filter bag 2, first put the filter bag 2 on the surface of the support column 4, place the filter bag 2 between the pressure ring 32 and the arc ring 31, and screw the first screw 33. The first screw 33 is engaged with the thread of the arc ring 31, and the first screw 33 drives the pressure ring 32 to squeeze the filter bag 2, so that the filter bag 2 is fixed between the pressure ring 32 and the arc ring 31. Place the guide block 61 and the pressure block 62 on both sides of the surface of the support column 4, and screw the second screw 63. The second screw 63 is engaged with the thread of the guide block 61, and the second screw 63 will squeeze the pressure block 62.

The first screw 52 is fixed on the surface of the support column 4 to facilitate the installation of the transmission assembly 5. By rotating the limiting ring 12, the limiting ring 12 drives the power rod 11 to rotate, and the power rod 11 drives the transmission plate 51 to rotate. By rotating the transmission plate 51, the transmission plate 51 drives the first screw 52 to rotate, and the first screw 52 rotates inside the first screw sleeve 53. Since the first screw sleeve 53 is fixedly connected to the support rod 54, the support rod 54 can be fixed to the surface of the support column 4 by the locking structure 6. The first screw 52 drives the bearing 7 and the connecting plate 8 to move. When the connecting plate 8 moves, the connecting plate 8 drives the first connecting rod 91 to move through the first rotating shaft. The first connecting rod 91 is driven by the second rotating shaft. The movable connecting seat 92 moves, and the connecting seat 92 will drive the second connecting rod 93 to move. Since the second connecting rod 93 is fixedly connected to the rotating ring 94, and the rotating ring 94 is sleeved on the surface of the third connecting rod 95, the second connecting rod 93 will rotate around the surface of the third connecting rod 95 through the rotating ring 94. At the same time, the second connecting rod 93 will drive the arc-shaped pressing block 96 to move, so that the arc-shaped pressing block 96 presses against the filter bag 2, so that the filter bag 2 contacts the surface of the mounting plate 1, thereby achieving the limit fixation of the overall structure. At the same time, the power rod 11 can be inserted into the inner part of the limiting ring 12 at a distance, and the limiting ring 12 can be rotated at a distance. At the same time, the hook can be hung inside the limiting ring 12 for convenience. The movement of the overall structure, when the third screw 101 is screwed into the interior of the second connecting rod 93, the second screw sleeve 102 is threadedly matched with the third screw 101. Since the second screw sleeve 102 is fixedly connected to the counterweight 103, the spring 13 is prevented from being in a working state when it is not working. When the filter bag 2 is installed on the mounting plate 1, when the third screw 101 and the second screw sleeve 102 are disengaged, the spring 13 will flexibly connect the second connecting rod 93 and the second screw sleeve 102. Therefore, when air passes through the counterweight 103, the counterweight 103 will drive the second screw sleeve 102 and the spring 13 to shake slightly. Through the shaking of the counterweight 103, the dust on the surface of the filter bag 2 can be removed.
