Zusammenfassung:The utility model relates to a mechanical field, particularly a light-duty and distance variable lifting and supporting device. An original product is an air spring, and a supporting rod can not be controlled to retract after extended out and can only be retracted by pressurizing forcefully. A combination valve is arranged inside a telescopic rod by the light-duty and distance variable lifting and supporting device. The two-way control of extension and retraction can be realized. The light-duty and distance variable lifting and supporting device has the advantages of compact structure and flexible and convenient use. The light-duty and distance variable lifting and supporting device also has interchangeability with the air spring, and can be widely used for industries of automobiles, textiles, medical service, construction, etc.
