Abstract

A gimbal system, a gimbal and a locking device are provided. The locking device is configured to be disposed on the shaft arm. The locking device includes an upper cover, a lower cover, a quick release plate and a locking assembly. The upper cover is disposed on the shaft arm. The lower cover is disposed on the side of the shaft arm opposite to the upper cover, and the upper cover and the lower cover can move together along the first direction. The quick release plate is used to install a load. The quick release plate is disposed on the side of the upper cover away from the lower cover. The quick release plate can move along a second direction on the upper cover. The locking assembly passes through the lower cover and the upper cover. When the locking assembly is tightened, the upper cover and the lower cover are locked and fixed to the shaft arm, and the quick release plate and the upper cover are locked and fixed on the upper cover.
