The invention provides an underwater propelling device. The underwater propelling device comprises a machine body, a power module and a connecting kit. The connecting kit is arranged between the machine body and the power module in a sleeving mode, and detachable assembly of the machine body and the power module is achieved. The connecting kit comprises a connecting module and a locking module. The connecting module comprises two connecting pieces which are connected end to end, the two connecting pieces are matched to define a hollow annular structure, one end of the hollow annular structure is arranged at the end of the machine body in a sleeving mode, and the other end of the hollow annular structure is arranged at the end of the power module in a sleeving mode. The locking module controls the connecting module to be switched between a first working state and a second working state, when the connecting module is in the first working state, the machine body can freely rotate relative to the connecting module, and meanwhile the power module can freely rotate relative to the connecting module; and when the connecting module is in the second working state, the machine body, the connecting module and the locking module are relatively locked and fixed into a whole. Meanwhile, the invention further provides a connecting piece and a connecting structure which adopt the quick-release connecting kit.
