專利摘要 A pressure release mechanism has a securing end, a detaching end and an activation piston. An inner cylinder and an outer cylinder in communication with the inner cylinder are defined in the securing end. A concave annular recess is defined in the inner periphery of the outer cylinder. A spring is compressed in the inner cylinder. The activation piston has a first extension and a second extension respectively extending from opposite ends and an annular groove defined to receive therein an O-ring. Multiple holes ate radially defined in the detaching end to receive balls. A cylinder in communication with the outer cylinder of the securing end is defined in the detaching end, and an axial hole is defined in the detaching end to communicate with the cylinder and the external environment. When the activation piston is movably received in the detaching end cylinder and the securing end outer and inner cylinders, the balls in the holes are held in the concave annular recess. When the balls are released from the annular recess due to the movement of the first extension, the securing end is detached from the detaching end.
