[0007] As a further improvement of the above scheme, the end rod mechanism includes an end rod body and an end plate, the end plate is symmetrically connected to the top of the fixed frame, the end rod body passes through the hole on the end plate, the outer surface of the end rod body is connected to the end plate, the upper end of the end rod body is fitted with a tension spring, the lower end of the tension spring is connected to the end plate, the upper end of the tension spring is connected to the bracelet, and the bracelet is connected to the upper end of the end rod body; through the tension of the tension spring, the end rod body is inserted into the hole of the end plate, and an upward tension is applied to the bracelet. The end rod body is displaced upward, and its lower end loses the function of blocking the movement of the limit frame, and the limit frame will slide out of the fixed frame. If the bracelet has no external force, the end rod body will be displaced downward under the tension of the tension spring to block the displacement of the limit frame, and the end plate limits the end rod body to prevent the end rod body from completely separating from the end plate.

[0008] As a further improvement to the above solution, the outer end of the bolt plug shall not exceed the outer surface of the limit frame to avoid sliding displacement of the limit frame.

[0009] Compared with the prior art, the utility model has the following advantages: simple structure, reasonable design, novel and unique concept, adopts a groove-rail frame structure, and the filter is positioned more accurately by snapping on. The filter frame is restricted to prevent the frame from shaking, thereby ensuring the service life of the filter and preventing the filter from being damaged due to shaking of the frame. At the same time, the filter of the present application is convenient and quick to replace. BRIEF DESCRIPTION OF THE DRAWINGS
