Complex hosel structure for a golf club head having a high degree of vibrational absorbability and elastic deformability

A golf club head having a complex hosel structure, comprising:

• a golf club head body including a striking plate, a toe-side portion, a sole portion, a crown portion and a heel-side portion, a neck portion located at the heel-side portion and a first connectin portion formed on the neck portion;
• and
• a complex hosel including a first tubular, segmental wall and a second tubular, segmental wall which are combined along a longitudinal direction parallel to an axial direction, the first tubular, segmental wall and the second tubular, segmental wall being made from a first material and a second material which are different, with dimensions of the first tubular, segmental wall being identical with those of the second tubular, segmental wall, the complex hosel further including a second connecting portion;
• wherein the first connectin portion of the golf club head body and the second connecting portion of the complex hosel are connected each other when assembled.
