The ball body is provided with a Z shaft sliding groove and an XY shaft sliding groove perpendicular to the Z shaft sliding groove, and the ball body and the Z shaft can relatively rotate around the Z shaft. The Z shaft, the X shaft and the Y shaft are perpendicular to one another, and the X shaft and the Y shaft are placed horizontally and can only rotate along the respective axes. The connecting end of the X shaft and the ball body and the connecting end of the Y shaft and the ball body are both fixedly connected with sliding strips, an arc-shaped sliding groove is formed in the movable sliding channel, the two side faces of the sliding strips are in contact with the two side faces of the arc-shaped groove to form clearance fit, and the sliding strips slide in the arc-shaped groove. The two side faces of the sliding block are in contact with the two side faces of the XY shaft sliding groove in the ball body to form clearance fit, and the sliding block can slide in the XY shaft sliding groove. One ball joint can drive three shafts which are perpendicular to one another to rotate, a spatial rotating angle can be decomposed to all the perpendicular shafts timely and accurately, and the problem that a spatial three-dimensional rotating angle is changed to be a planar two-dimensional rotating angle is solved. The ball joint three-dimensional shaft is simple in structure and ingenious in structure, and has high practical value.
