The invention discloses a carbon fiber composite material ball head node and a connecting method thereof. The ball head node comprises a ball head, T-shaped screws and concave nuts; the ball head, the T-shaped screws and the concave nuts are all made of carbon fiber materials, the ball head is of a hollow ball structure, a plurality of long holes are formed in the ball head, the length of each long hole is larger than the width of each long hole, and each long hole is provided with one T-shaped screw and one concave nut and is connected with one pipe fitting. The connecting method comprises the steps that the ball head is slightly clamped by the T-shaped screws and the concave nuts, then the direction of the axis of each T-shaped screw is adjusted to a design value, finally, each concave nut is tightened, and the thread meshing positions and the contact positions of the concave nuts and the ball head are coated with epoxy resin glue and cured. Other structures are not needed for supporting and assisting solid
