The filter holder according to claim 2, wherein the first moving body and the second moving body are integrally formed elastic bodies capable of completing rotation of the second moving body relative to the first moving body and rotation of the second holder by means of elastic deformation of the elastic bodies themselves.

6. The filter holder according to claim 2, wherein the first holder is provided with a receiving groove, the moving member is slidably provided in the receiving groove, the moving member can extend out of the receiving groove to move the second holder away from the first holder, and the moving member can retract into the receiving groove.

7. The filter holder according to claim 6, wherein one of the first moving body and the first holder is provided with a slider, and the other is provided with a slide groove; the sliding block is accommodated in the sliding groove and can move along the sliding groove under the drive of the moving piece, so that the moving piece extends out of the accommodating groove; the moving piece further drives the sliding block to reversely move along the sliding groove, so that the moving piece retracts into the containing groove.

8. The filter holder according to claim 7, wherein one of the first moving body and the first holder is provided with a clip, the other is provided with a clip groove, and the clip groove is formed at the bottom of the chute; the clamping column is accommodated in the clamping groove and can move along the clamping groove under the drive of the moving piece, so that the moving piece extends out of the accommodating groove, and when the clamping column moves to the limit, the clamping column abuts against the groove wall of the clamping groove, so that the moving piece is limited to be separated from the accommodating groove; the moving piece can also drive the clamping column to reversely move along the clamping groove, so that the moving piece retracts into the containing groove.

9. The filter holder according to claim 1, wherein the first holder is provided with a first magnet by which the first holder can be magnetically attracted to a housing of an electronic device.

10. A light filtering device, comprising:

a filter holder according to any one of claims 1 to 9; and

the filter lens is detachably connected to the second bracket; the second bracket is provided with a second magnet, the filter lens is provided with a third magnet, and the filter lens can be fixed on the second bracket through magnetic attraction between the third magnet and the second magnet; the filter can also overcome the magnetic attraction between the third magnet and the second magnet to disengage from the second bracket.
