Main cone elastic guide press-loading device

The invention relates to a main cone elastic guiding pressing mechanism. The mechanism is characterized in that a lower supporting pressure head which can dynamically go upward along the axial point of a lower oil cylinder in a double acting compressor system, the lower supporting pressure head is a casing pipe structure, a guiding pressure head is coaxially arranged inside the inside the lower supporting pressure head pipe, the end surface of the tail end of the guiding pressure head is supported by a pressure spring inside the lower supporting pressure head pipe, and the guiding pressure head can axially slide inside the lower supporting pressure head pipe; the upper section of the guiding pressure head is a truncated cone body with larger upper end and smaller lower end, the upper section pipe of the lower supporting pressure head is a straight pipe section which can hold the truncated cone body, the truncated cone body in the upper section convexly of the guiding pressure head supported by the pressure sp
