Furthermore, the accessory A comprises a main board A and two side boards A, the two side boards A are respectively and vertically connected with the left side edge and the right side edge of the main board A, through holes A are formed in the side boards A, the positions of the through holes A correspond to those of the through holes A, the accessory B comprises a front panel B and two side panels B, through holes B are formed in the side panels B, and a shaft rod penetrates through the through holes A and the through holes B so that the accessory B can freely rotate around a shaft; and a cross rod is arranged on the accessory B and is used as a hooking point with the accessory C and also used as a transmission point.

The accessory C comprises a C main board, a C upper hook board and a C lower hook board, wherein the C upper hook board is L-shaped, the C upper hook board is arranged at the top end of the C main board and used for hooking with a filter, the C lower hook board is arranged at the bottom end of the C main board, and the C lower hook board is arranged at an angle of 45 degrees with the C main board and used for hooking with a cross rod on the accessory B. In order to enable the accessory C to rotate freely without rubbing with other parts in the using process, the width of the accessory C can be made smaller, or notches are arranged on two sides of one end of the accessory C close to the lower hook plate of the accessory C, so that the accessory C is prevented from contacting with other parts (such as screws) on two sides.

The device can select the installation position and the number on the supporting frame according to the actual situation.

Has the advantages that: the filter is convenient to detach and replace while the connection between the filter and the support frame is ensured to be sufficiently and firmly; fittings of different lengths can be replaced to accommodate different models of filter requirements.
