The invention discloses an automatically resettable buoy comprising a coil spring. The automatically resettable buoy comprises a buoy body, an anchor chain and an anchor block; the anchor block is connected with the lower end of the anchor chain; the center of the upper end of the buoy body is provided with the coil spring; two vertical sleeve pipes are symmetrically arranged on the lateral sides of the buoy body respectively; the upper end of each sleeve pipe is provided with a rolling wheel frame which is fixed at the upper end of the buoy body; each rolling wheel frame is provided with a rolling wheel; the anchor chain comprises a lower anchor chain and two upper anchor chains; the lower end of each upper anchor chain is connected with the upper end of the lower anchor chain; the upper end of each upper anchor chain penetrates the corresponding sleeve pipe and rolling wheel to wind the coil spring. According to the automatically resettable buoy comprising the coil spring, the automatic adjustment on the length of the anchor chain can be implanted in the process of dramatic changes of the water level and accordingly the extreme conditions of leapfrogging of the anchor block, submerging of a buoy body or drifting-away of the buoy body of the buoy are avoided and meanwhile the fracture or knotting force of the buoy due to the fixed anchoring length can be avoided and accordingly the drifting or swing radius of the buoy can be within the permitted range.
