The invention discloses a buoy provided with an annular slide block system and capable of automatically resetting. The buoy comprises a buoy body, an anchor chain and an anchor block. The annular slide block system is arranged on the buoy body and comprises at least three movable blocks which are arranged on a perpendicular face and rotate around a rotation center. Slide block sleeves are arranged at the outer ends of the movable blocks. A compression spring is connected between every two adjacent movable blocks. The anchor chain sequentially penetrates the sliding sleeves of all the movable blocks and is fixed to the last movable block. A guide sleeve is arranged below the joint position of the circle where the sliding sleeves are located and the vertical tangent line. The anchor chain penetrates the guide sleeve. The length of the anchor chain can be automatically regulated through the buoy when the water level violently changes, and therefore it is ensured that extreme situations such as anchor block leapfrogging, buoy body submerging or drifting can not happen to the buoy; and buoy breaking or knotting caused by the fixed mooring length can be avoided as well, and it is ensured that the buoy drifting and gyration radii are within the allowable range.
