The invention discloses a locking piece type underwater rapid locking device. The locking piece type underwater rapid locking device comprises a connecting cover plate and a locking piece control mechanism. According to the structure of the locking piece control mechanism, a remotely operated vehicle (ROV) handle is arranged in an operating mounting hole of an ROV panel; a fixed sleeve is disposed inside the connecting cover plate, and locking pieces are correspondingly arranged in multiple lock holes in the outer wall of the fixed sleeve; the outer wall of the fixed sleeve is sleeved with a floating sleeve, and handle lock holes are formed in the wall of the floating sleeve; a bush is arranged on the surface of an inner cavity of the fixed sleeve, and a round through hole is formed both in the wall of the fixed sleeve and the wall of the bush; an inner cavity of the bush is provided with a locking shaft, and a semi-cylindrical lock groove is formed in the upper portion of the outer wall of the locking shaft; at least one round-angle trapezoidal groove is formed in the lower portion of the outer wall of the locking shaft, and the position of each round-angle trapezoidal groove corresponds to that of the corresponding locking piece; a guiding shaft is disposed at the upper end of the locking shaft, and a spring is arranged between the outer wall of the guiding shaft and a blind hole of the axis of the locking shaft in a sleeving mode. The locking piece type underwater rapid locking device is simple in structure and can work reliably.
