[0035] When the filter is in use, the anti-reflection film 2 is provided to improve the transmittance of visible light. At the same time, the protective film 3 is provided to effectively protect the filter. In order to prevent the filter from being completely deformed during use, the distance between the multiple blocks 4 can be adjusted according to the specifications of the filter, so that the adjustment plate 7 can move laterally under the sliding cooperation of the support rod 6, and under the connection of the connecting frame 8, the multiple adjustment plates 7 can slide on the surface of the block 4, so that filters of different specifications can be stably inserted into the plug-in groove 13 on the side wall of the block 4, and through the plug-in cooperation of the positioning plate 10 and the positioning groove 12 on the side wall of the adjustment plate 7, and the elastic force of the first spring 11, the multiple blocks 4 can stably limit and clamp the filter to avoid deformation of the filter due to long-term use.

[0036] Example 2

[0037] Embodiment 2 is based on Embodiment 1, in order to separate the positioning plate 10 from the adjustment plate 7 when the position of the adjustment plate 7 is adjusted, so as to improve the convenience of adjustment.
