The fixing ring 110 is used for connecting a lens, the first mounting ring 120 is rotationally connected with the fixing ring 110, the second mounting ring 130 is rotationally connected with the first mounting ring 120 and is located on the side of the first mounting ring 120 away from the fixing ring 110, the first filter 140 is arranged on the first mounting ring 120, the second filter 150 is arranged on the second mounting ring 130 and is located on the side of the first filter 140 away from the fixing ring 110, and the positioning piece 160 is rotationally connected with the second mounting ring 130 and is configured to abut against the first mounting ring 120. Wherein, the rotation shaft of the first mounting ring 120 and the rotation shaft of the second mounting ring 130 are arranged in coincidence, and when the positioning piece 160 abuts against the first mounting ring 120, the first mounting ring 120 and the second mounting ring 130 can synchronously rotate relative to the fixing ring 110.

[0048] In the multifunctional filter 100, the first filter 140 can be driven to rotate relative to the second mounting ring 130 through the first mounting ring 120, the second filter 150 can be driven to rotate relative to the first mounting ring 120 through the second mounting ring 130, and when the positioning piece 160 abuts against the first mounting ring 120, the first mounting ring 120 and the second mounting ring 130 can be synchronously driven to rotate relative to the fixing ring 110 through the positioning piece 160, so that the adjustment mode of the multifunctional filter 100 is increased, and the application range of the multifunctional filter 100 is expanded.
