Beschreibung
Zusammenfassung:	The gas spring structure comprises a nitrogen chamber and an oil chamber which are connected with each other, the nitrogen chamber comprises a nitrogen cavity outer cylinder, one end of the nitrogen cavity outer cylinder is connected with an upper connecting outer cylinder, the other end of the nitrogen cavity outer cylinder is connected with an oil chamber outer cylinder of the oil chamber, and a nitrogen cavity mandrel is arranged on the inner side of the nitrogen cavity outer cylinder in the axial direction of the nitrogen cavity outer cylinder and penetrates through the upper connecting outer cylinder; a cavity for containing nitrogen is formed between the nitrogen cavity outer cylinder and the nitrogen cavity mandrel, an upper pressure transmitting hole is formed in the position, opposite to the cavity, of the nitrogen cavity outer cylinder, and annular pressure enters the cavity through the upper pressure transmitting hole to achieve movement of the nitrogen cavity mandrel. An oil chamber mandrel is arr
