Portable gas chromatographic analyzer

The utility model provides a gas chromatographic analyzer convenient to carry, which belongs to the technical field of medical equipment and is characterized in that the bottom of an analyzer shell is attached to the upper part of a corrugated pad II, and when the device bumps up and down in a transfer process, the analyzer shell is squeezed by liquid in the corrugated pad II due to gravity and rushes into a pipeline I; in the second pipeline, the water flow extrudes a limiting gasket and a second spring, so that the limiting gasket moves towards one side of the second pipeline by a certain distance. According to the scheme, the analyzer shell is clamped into the base, then the motor rotates reversely to release the steel wire, then the corrugated pad is reset through the spring, and the corrugated pad stretches to enable one side surface of the corrugated pad to be attached to the analyzer shell, so that the periphery of the analyzer shell is fixed, and meanwhile, the periphery of the analyzer shell can be b
