Shark pincers with emergent release function

The invention relates to shark pincers with an emergent release function, belonging to the field of towing equipment for a ship. The shark pincers provided by the invention comprise a shark pincers executing system, a hydraulic master control system, a dynamical system and an emergent release device, wherein an oil outlet pipe of the power system is provided with a master oil-way check valve; and the emergent release device is connected in parallel to the oil outlet pipe between the master oil-way check valve and the hydraulic master control system. When the shark pincers normally work, the power system supplies oil to an energy accumulator of the emergent release device, so that a sufficient amount of high-pressure oil is accumulated in the energy accumulator. When the power source of the shark pincers fails, the high-pressure oil in the energy accumulator flows back to the hydraulic master control system to supply a power source to the hydraulic master control system, thereby finishing the emergent release
