Description

Camera accessory and camera system Technical Field The present application relates to the field of camera technologies, and in particular, to a camera accessory and a camera system. Background In the existing camera, a bolt structure on a camera body is usually utilized, and a bolt groove on a camera accessory is matched to lock the camera accessory and the camera body, so that relative rotation of the camera accessory after the camera accessory is mounted on the camera body is limited. But the latch structure is too small, the locking effect is poor, and the stability is poor. Disclosure of Invention The application provides a camera accessory, which is used for realizing the purpose that the camera accessory is firmly locked on a camera body. The camera accessory comprises a second mounting seat and a locking structure, wherein the second mounting seat comprises a plurality of second claws, the second mounting seat is configured to rotate relative to the first mounting seat between a first state and a second state, the second claws are inserted between the first claws in the first state, the second claws are clamped with the first claws in the second state, the locking structure is movably arranged on an outer ring surface of the second mounting seat, which is engaged with the first claws, when the second mounting seat rotates between the first state and the second state relative to the first mounting seat, the locking structure is retracted into the outer ring surface, when the second mounting seat rotates relative to the first mounting seat, the second mounting seat is buckled with the first claws to limit the second mounting seat to rotate from the second state to the first state. In one embodiment, the camera accessory further comprises an accessory shell, a second mounting seat and an unlocking key, wherein the second mounting seat is arranged at the end part of the accessory shell, the unlocking key is arranged on the side surface of the accessory shell and connected with the locking structure, and acts on the locking structure to enable the locking structure to retract into the outer annular surface so as to unlock the locking structure and the first clamping jaw.
