Abstract:
A connecting structure of a filter holder (10) and a light shield holder (20), comprising the filter holder (10) and the light shield holder (20). The light shield holder (20) is detachably connected to the filter holder (10). Two filter mounting members (11) are symmetrically provided on the filter holder (10), and a single filter mounting member (11) is provided with at least one limiting member (12); the light shield holder (20) comprises a holder body (21) and adjusting members (22) in one-to-one correspondence to the limiting members (12), and the adjusting members (22) are rotatably connected to the holder body (21). The adjusting members (22) are rotated to enable the adjusting members (22) to abut against the limiting members (12), so that the light shield holder (20) and the filter holder (10) form a fixed connection. The connecting structure of the filter holder (10) and the light shield holder (20) enables the light shield holder (20) to be fixedly connected to the filter holder (10), so that a filter and a light shield can be simultaneously mounted on a camera.
