High-pressure-resistant tooling joint

The invention relates to the field of ships and ocean engineering, in particular to a high-pressure-resistant tooling joint used for sealing and fixing pipes. The high-pressure-resistant tooling jointincludes a transmission mechanism. One end of the transmission mechanism is movably connected with a sealing plug used for sealing the end parts of the pipes. The other end of the transmission mechanism is movably connected with an adjusting wrench used for driving the sealing plug to move back and forth. The high-pressure-resistant tooling joint further includes a flange clamping plate used forfixing the pipes. The flange clamping plate is fixed on the transmission mechanism through a connecting arm. The sealing plug and the flange clamping plate are arranged relatively parallelly. The transmission mechanism is provided with at least two hanging lugs. The high-pressure-resistant tooling joint is simple in structure, convenient to use and easy to operate and is not limited by the construction space and the constr
