Abstract:
1. An apparatus for connecting and disconnecting first and second objects, comprising: a hollow housing having one closed end to which the first object is connectable and an opened end; a coupling portion mounted in the housing so as to be movable in an axial direction of the housing, and to which the second object is connectable; a clamping portion coupled to the housing for clamping the coupling portion; a cylinder disposed in the housing for pressurizing the clamping portion so that a clamped state of the coupling portion by the clamping portion can be maintained; wherein the clamping portion comprises: a fixing portion coupled to the housing and the cylinder for fixing the cylinder to the housing so that the cylinder can maintain a pressurizing state onto the clamping portion, wherein the fixing portion is a tension bolt penetrating the closed end of the housing thus coupling to one side of the cylinder; and a gas generator integrally coupled to an outer surface of the housing so as to be in communication with an inner space of the housing for generating gas of high pressure above a predetermined threshold thereby breaking the tension bolt, releasing a clamped state of the coupling portion, and separating the coupling portion from the opened end of the housing.
