Lens limiting assembly, camera body, and camera module

A lens limiting assembly (100), used for limiting a lens (310) whose outer side is provided with a clamping portion (314). The lens limiting assembly (100) comprises an elastic element (10), a lens assembly ring (20), and a locking ring (30). The lens assembly ring (20) is fixedly disposed on the elastic element (10). The lens assembly ring (20) is provided with a limiting portion (22) and a first inclined surface (24). After the lens (310) is rotationally assembled in the lens assembly ring (20), the clamping portion (314) is clamped below the limiting portion (22) and the elastic element (10). The locking ring (30) is provided with a hook (32). The hook (32) abuts between the first inclined surface (24) and the elastic element (10). When the locking ring (30) rotates towards a direction, at least one part of the hook (32) moves on the first inclined surface (24) and presses the elastic element (10) along with the increase of the height of the first inclined surface (24), the elastic element (10) presses the clamping portion (314) of the lens, and accordingly, the lens (310) is locked.
