Beschreibung
Zusammenfassung:	The pressure-adjustable gas spring comprises a cylinder body and a piston rod movably arranged at the head end of the cylinder body, the interior of the cylinder body is divided into a gas storage cavity and an oil storage cavity, and a pressure adjusting device is arranged at the tail end of the cylinder body; the pressure adjusting device comprises a pressure adjusting piston arranged in the cylinder body, a guide piece fixed to the tail end of the cylinder body and a pressure adjusting rod in threaded connection with the guide piece, and the pressure adjusting rod drives the adjusting piston to move in the axial direction of the cylinder body so as to adjust the volume of the air storage cavity. According to the scheme, the dynamic force of the air spring is adjusted through the pressure adjusting device, the bearing range of the air spring is changed, the air spring is suitable for supporting or traction of heavy objects of different specifications under the condition that the air spring is not replaced,
