The invention discloses a fixing apparatus for Freon pressurizing liquefaction. The fixing apparatus comprises a bearing rod, wherein a plurality of rod grooves are arranged on the middle portion of the bearing rod, one side of the rod grooves is provided with a plurality of bearing grooves, one end of the bearing rod is provided with a braking rod, both sides of the bearing rod are respectively provided with a side plate, one side of the bearing rod is provided with a position limiting plate, the edge of one side of the position limiting plate is provided with a plurality of position limitinggrooves, a position limiting plate seat is arranged below the position limiting plate, an apparatus seat is arranged below the position limiting plate seat, one side of the apparatus seat is providedwith a fixing plate, and the other side of the bearing rod is provided with a fixing rod. According to the present invention, the user directly installs the pressurizing device on the fixing apparatus through the bearing grooves, and connects the gas inlet pipe to the pressurizing device, such that the high pressure can be generated when the gas is pressurized; and the position limiting plate canmaintain the stable state of the bearing rod through the position limiting grooves and the rod grooves so as not to generate displacement.
