Decapping structure of high pressure container and high pressure container employing same

The invention provides a decapping structure of a high pressure container and the high pressure container employing the same. The decapping structure of the high pressure container comprises a valve body. The valve body is provided with a communicating pipe, a cut-off pin, an exhaust channel and an exploder, wherein one end of the communicating pipe communicates to a gas outlet of a bottle body while the other end of the communicating pipe is closed; the cut-off pin is used for cutting the communicating pipe off, and is provided with a stress end and a cut-off end; the exhaust channel communicates to a fracture of the communicating pipe after the communicating pipe is cut, so that gas in the bottle body is exhausted through the communicating pipe and the exhaust channel; the exploder is used for applying an external force to the cut-off pin by generating high pressure gas after detonation; and the cut-off end of the cut-off pin is columnar, a groove matched with the cut-off end in shape to form a convex-conca
