This equipment can do (rotation, transvers and longitudinal shift) unidirection movement and interaction of two degrees of freedom or more degrees of freedom. Its core technology for dynamic seal technology, has many advantage like high pressure resistance, reliable structure, failure protecting and alarming, etc.

　　It can also promote specimen under high pressure of 20Mpa to move up and down, back and forth and 360 °rotation, and combine of any two movement or three at the same time.
