A multiple-axis vertebra fixed rod includes a first joint rod, one end of which is the pole end, another end is the joint end, the joint end near the pole end essentially is formed as ball-arc a second joint rod, which is similar to the first joint rod a first joint cup having a cup body, at least portion of bottom of said cup body essentially is formed as ball-arc shape and curvature of which is essentially identical to the curvature of ball-arc of the joint rods joint end so as to form a universal joint when combined with the ball-arc of the joint rods joint end. Ball arc of said cup body has a through hole that allows pole end of the joint rod to pass from the first joint cup interior through to exterior a second joint cup, which is similar to the first joint cup and a joint part, one side of which is combined with the joint end of the first joint rod, another side is combined with the joint end of the second joint rod. The first joint cup and the second joint cup are combined with screw or engaging mechanism.
