Abstract A six-freedom parallel mechanism with nearly orthogonal three axes is composed of static table body, movable table body and 6 drive rods which can stretch out and draw back in length and are pivoted to static and movable table body via the ball hinges at their both ends. It featurs that said 6 drive rods are respectively in or thogonal or nearly orthogonal at X, Y and Z directions, two for each direction. Said movable table body can be positioned at the central space position of 6 drive rods or their upper or lower parts. When it is at the central position, X, Y and Z axes are decoupled, so resulting in simple regulation, easy control and wide application.
