[0016] Compared with the prior art, the advantages of the present utility model are as follows:

[0017] First, in the present utility model, through the provided installation component, when it is necessary to disassemble the filter plate, a pulling force is applied to the movable rod. The spring is in a compressed state, driving the limiting column to disengage from the installation frame and the inside of the limiting block. Under the action of gravity, when the limiting block is not restricted, the limiting block moves downward inside the installation frame, thereby driving the connecting plate to disengage from the inside of the fixed pipe.

The rotating column and the limiting rod are on the same horizontal line. A pulling force is applied to the limiting plate to pull out the limiting rod from the inside of the fixed frame. When the spring is in a compressed state, the movable rod is pulled outward, driving the guiding plate to move synchronously. After the movable block moves to one side of the fixed frame, the limiting rod is aligned with the limiting hole. A pushing force is applied to the limiting plate to insert the limiting rod into the fixed frame and the inside of the movable block. Then, a downward turning force is applied to the rotating column. This solution can stably fix the movable rod to the required position, thus facilitating the removal of the filter plate from inside the ventilation holes. Description of the Drawings
