Auxiliary clamping device of isothermal adsorption tank

The utility model discloses an auxiliary clamping device of an isothermal adsorption tank, which relates to the field of clamping devices and comprises a fixing frame, third rotating shafts are rotatably arranged at two ends of the fixing frame, a plurality of first arc-shaped rotating plates are rotatably arranged on outer rings of the two third rotating shafts, and a plurality of second arc-shaped rotating plates are rotatably arranged on the outer rings of the first arc-shaped rotating plates. In the actual operation of the tank body pressing device, when the air cylinder continues to apply pressure to enable the telescopic end to stretch out, the second arc-shaped rotating plate continues to apply extrusion force to the surface of the tank body at the moment, the tank body makes contact with the arc-shaped base plate at the moment, and therefore the tank body can be pressed. The arc-shaped base plate can extrude the telescopic piece and the elastic air bag under pressure, the elastic air bag is extruded t
