[0002] A filter is a device used to filter ambient air. Its core component is the filter element, which needs to be installed and fixed inside the filter. However, because the filter element accumulates dust when processing exhaust gas, it needs to be replaced or cleaned regularly. Existing filter element structures typically use multiple screws to secure the filter element frame to the frame. While this connection method is simple and secure, it suffers from low connection efficiency. Furthermore, tools required to tighten the bolts cannot reach into confined spaces, making assembly and disassembly inconvenient. Utility Model Content

[0008] Furthermore, a rotating shaft body is fixed on the connecting plate; synchronous wheels are fixed on both the rotating member and the rotating shaft body; the synchronous member is a synchronous belt; and the synchronous belt is connected to each synchronous wheel.

[0012] Furthermore, the number of the rotating extrusion members is three.

[0013] After adopting the above structure, the beneficial effects of the utility model are as follows: before the filter element body is inserted into the installation cavity, the rotating extrusion module is misaligned with the installation cavity; after the filter element body is inserted into the interior of the installation cavity from the side opening, the rotating extrusion module moves so that the rotating extrusion module faces the filter element body and presses the filter element body tightly against the inner wall of the installation cavity; when the filter element body needs to be removed, the rotating extrusion module moves again and is misaligned with the filter element body.
