The invention belongs to maintenance and overhaul technologies for nuclear power station equipment and particularly discloses underwater pneumatic pliers. The underwater pneumatic pliers comprise a long connection rod, a pliers body angle adjusting part and a cylinder, and further comprise an adapter sleeve connected with the cylinder and pliers bodies connected with the adapter sleeve. The pliers bodies comprise the upper pliers body and the lower pliers body. The upper end of the upper pliers body is connected with the upper end of the lower pliers body through a shaft. An expansion rod is arranged on the cylinder and is capable of moving in the adapter sleeve in the axial direction, the end of the expansion rod is in shaft connection with one end of an adapter rod, and the other end of the adapter rod is in shaft connection with the lower end of the lower pliers body. According to the underwater pneumatic pliers, the cylinder and an air source are used as air feeding devices, and compression air is used as power so that air source power can be obtained conveniently; meanwhile, control equipment such as a control hand valve and a control air tube is used for achieving remote control. The underwater pneumatic pliers have the advantages of being clean and clear free of hydraulic oil leakage polluting a water pond and the like; compared with a pure machine tool, the underwater pneumatic pliers are small in size, low in weight, high in work efficiency and reliable in motion realization.
