The invention discloses a hydraulic pressure spring device for adjustment of artificial limb joint movement. The device comprises a hydraulic driving mechanism and a flexible energy storage mechanism which is arranged in a liquid chamber of the hydraulic driving mechanism; the flexible storage mechanism matches with the piston motion of the hydraulic driving mechanism, through which a flexible hydraulic driving pattern is formed. The hydraulic pressure spring device for adjustment of artificial limb joint movement can give an artificial limb joint movement part some buffer and support during the vertical movement, and can make speed and angle produced during the artificial limb joint movement close to that produce during the healthy limb joint movement. Besides, the hydraulic pressure spring device for adjustment of artificial limb joint movement has a high cost performance, can replace similar-type foreign products, and has very high stability and reliability.
