BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a golf club head, and more particularly to a technology of attaching an inner board to the internal surface of the striking surface of a golf club head. [0003] 2. Description of the Prior Arts [0004] Golf club heads are generally classified into two types. A first type golf club head A as shown in FIG. 1 comprises a head portion 300, at the front of the head portion 300 is formed a groove 301 in which is provided a striking board 400 by soldering method. However, when the striking board 400 strikes the golf ball, strong vibrations will be caused, thus probably leading to a broken of the striking board 400 from the head portion 300. [0005] A second type golf club head A as shown in FIG. 2 comprises a front head portion 100 and a rear head portion 200. At the front of the front head portion 100 is defined a striking surface 101 for striking the golf ball. However, the striking surface 101 must be thick so as to produce a striking force strong enough for striking the golf ball. Hence, the center of gravity of the golf club head A moves forwards, accordingly, the stability of the golf club, the flying stability of the golf ball and the distance that the golf ball travels cannot be effectively controlled. Furthermore, the position of the center of gravity of the golf club head A cannot be designed arbitrarily according to needs. [0006] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. SUMMARY OF THE INVENTION [0007] The primary objective of the present invention is to provide a golf club head, on the internal surface of the striking surface of the head portion of the golf club head is formed an annular wall, and an inner board disposed between the annular wall and the striking surface shifts the center of gravity of the golf club head backwards, so that the height and the depth of the center of gravity of the golf club head can be designed according to needs so as to improve the flexibility of the balance weight of the golf club head, thus the stability of the golf club, the flying stability of the golf ball and the distance that the golf ball travels can be optimized. [0008] The secondary object of the present invention is to provide a golf club head whose inner board and striking surface are made of different materials, and the inner board is made of lightweight material having strong strength, so as to improve the strength and the elasticity of the striking surface of the golf club head. [0009] The further object of the present invention is to provide a golf club head, on an internal surface of its striking surface are formed an annular wall and at least a tightening pin, and the tightening pin is inserted in the inner board to tighten it, increasing the combination strength between the inner board and the striking surface. [0010] The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention. BRIEF DESCRIPTION OF THE DRAWINGS [0011] FIG. 1 is an exploded cross sectional view of a conventional golf club head; [0012] FIG. 2 is an exploded cross sectional view of another conventional golf club head; [0013] FIG. 3 is a cross sectional view of a part of a golf club head in accordance with the present invention; [0014] FIG. 4 is a perspective view of the golf club head in accordance with the present invention; [0015] FIG. 5 is a cross sectional view of the golf club head in accordance with the present invention; [0016] FIG. 6 is an enlarged view of a part of FIG. 5. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0017] Referring to FIGS. 3 and 4, a golf club head B in accordance with the present invention is shown and includes a head portion 10 at the front of which is integrally formed a striking surface 11 having a thin thickness. On the internal surface of the striking surface 11 are arranged an annular wall 12 and at least a tightening pin 13. Between the annular wall 12 and the striking surface 11 is provided at least an inner board 20, and the tightening pin 13 is inserted in the inner board 20 to tighten it, and so as to enable the inner board 20 to abut close against the internal surface of the striking surface 11 (as shown in FIGS. 5 and 6). The inner board 20 can be made of light metal material, such as aluminum, magnesium and the like, or the lightweight materials having strong strength and high elasticity, such as plastic, carbon fiber, nylon and the like. [0018] The inner board 20 between the striking surface 11 and the annular wall 12 is combined with the internal surface of the thin striking surface 11, so as to increase the strength and the elasticity of the striking surface 11 while reducing the weight thereof. [0019] As compared with the prior arts, the golf club head of the present invention has the following advantages: [0020] First, the internal surface of the striking surface 11 is combined with the inner board 20, and the center of gravity of the golf club head B moves backwards, so that the height and the depth of the center of gravity of the golf club head B can be designed according to needs so as to improve the flexibility of the balance weight of the golf club head B. Thus, the stability of the golf club, the flying stability of the golf ball and the distance that the golf ball travels can be optimized. Continue reading about Golf club head...
