Description

TECHNICAL FIELD The present disclosure relates to the technical field of photographic device, and in particular to a camera base plate. BACKGROUND In order to achieve good shooting effect, more and more photography enthusiasts use cameras or monitors combined with camera accessories, such as camera base plate, shoulder mount, quick release plate, and adapter bracket. The camera is provided with a battery compartment which defines an opening, and the opening is covered by a plate. Due to the limited capacity of the camera battery, it often needs to replace the camera battery during the shooting process. However, it is inconvenient to remove the camera from the camera base plate, so there is a need of the camera accessory (such as the camera base plate or camera protective frame), that is allowable for the replacement of the camera battery without removing the camera from the camera accessory. CN 211826862 U discloses a multifunctional camera base plate. The device includes a bottom plate and stretching side plates, a stretching groove is formed in the bottom plate; a fixed ring hole is formed in the stretching groove; wherein a stretching groove is formed in the bottom plate, a penetrating groove communicated with the stretching groove is formed in one side of the bottom plate, the stretching side plate is composed of a side plate body, a stretching block and a bolt, the side plate body is connected with the stretching block, the stretching block penetrates through the penetrating groove and is located in the stretching groove, and a first bolt hole matched with the first bolt is formed in the stretching block.
