       FIG.  1    is a perspective view according to an embodiment of a head fitting film for club head protection of the present invention, and  FIG.  2    is a use state view according to an embodiment of a head fitting film for club head protection of the present invention. 
     The present invention is described with reference to  FIGS.  1  to  2   . 
     A head fitting film for club head protection of the present invention includes a protective film  10 , an adhesive layer  20 , and a release paper  30  to be able to prevent a club head from being scratched and simultaneously adjust the weight and the center of gravity of the club head for head fitting by being attached to the outer surface of the club head. 
     The protective film  10  is made of synthetic resin film having elasticity and a predetermined thickness to be able to protect a club head by being closely attached to the surface of a club head. 
     In this case, the protective film  10  may be attached to surround the entire of a club head or may be attached to surround a portion of a club head. 
     It would be preferable that the synthetic resin film, which is the main material of the protective film  10 , is film made of synthetic resin such as polyester, polypropylene, polyvinyl chloride, and cellulose, and having a thickness of 1 mm or less and weight of 1 to 4 g, but it should be noted that the present invention is not limited thereto. 
     Accordingly, it is possible not only to more closely and firmly attach the protective film  10  to club heads formed with various curves, but also to prevent damage to a club head by absorbing impact, which is generated when a club head hits a golf ball, due to excellent elasticity of the protective film  10 . 
     As another example, materials such as metal and carbon may be mixed with the material of the synthetic resin film when fabricating the protective film  10 . 
     Accordingly, the wear resistance and durability of the protective film  10  are improved, and the weight is increased relative to a small thickness, thereby not only easily performing head fitting using the protective film  10 , but also preventing the surface of a club head having the protective film ( 10 ) attached thereto from being scratched because the protective film has a characteristic of being strong against friction. 
     As another example, the synthetic resin film may be fabricated such that the glossiness is lustrous, semi-lustrous, and non-lustrous types when fabricating the protective film  10 . 
     Further, the synthetic resin film may be fabricated such that the transparency is transparent, translucent, and opaque when fabricating the protective film  10 . 
     Further, there is no doubt that the material of the synthetic resin film may be fabricated in various colors including color paints when fabricating the protective film  10 . 
     Accordingly, it is possible decorate club heads in designs that users want using various glossiness, transparency, and colors, so it is possible to satisfy aesthetic tastes of users. 
     Meanwhile, the protective film  10  is divided into multiple segments corresponding to the external shapes of club heads. 
     Accordingly, the weight and center of gravity of a club head are adjusted in accordance with the number of segments and the position of the protective film  10  that is attached to the club head. 
     The adhesive layer  20  is formed on a side of the protective film  10 , thereby 
     providing an adhesive force for closely attaching and fixing the protective film  10  to a club head. 
     It would be preferable, as a method of forming the adhesive layer  20  on a side of the protective film  10 , to spray and apply an adhesive to a side of the protective film  10  in the process of fabricating the protective film  10 , but the present invention is not limited thereto. 
     The release paper  30  can be detachably attached under the adhesive layer  20  and protects the adhesive layer  20 , thereby preventing the adhesive layer  20  from being contaminated in the distribution process of the head fitting film for club head protection of the present invention, and when the protective film  10  is attached to a club head, the release film  30  is removed and then the adhesive layer  20  is directly bonded to the surface of the club head. 
     In this case, to easily remove the release film  30 , it is preferable to further apply a lubricant or further form a lubrication coating layer on a side of the release film  30  that is supposed to be brought in direct contact with the adhesive layer  20 , but it should be noted that the present invention is not limited thereto. 
     Meanwhile, the protective film  10  is divided into multiple segments corresponding to the external shapes of club heads. 
     That is, club heads are generally different in the shape, depending on the kinds of the clubs. For example, the club head of a driver that is used when hitting drive is composed of a face formed on the front of the club head to hit a golf ball, a crown formed on the top of the club head, a sole formed on the bottom of the club head, a tow formed on the outer surface of the club head, a heel formed on the inner surface of the club head, and a neck protruding upward from the inside of the club head to connect the club head and a shaft to each other, in which these parts are formed with different curvatures and shapes. 
     Accordingly, since it is technically very difficult to surround the entire of a club head with one sheet of protective film  10  formed to be flat, the protective film  10  is divided into multiple segments in accordance with the shapes of the parts of a club head, thereby more closely and firmly attaching the protective film  10  on the surfaces of club heads having various shapes and curves by selectively attaching the segments to the parts of the club heads, respectively. 
     Further, it is possible to increase the weight of a club head or adjust the center of gravity of a club head, depending on the attachment position of the protective film  10 . 
     That is, when the protective film  10  is attached to the tow formed on the outer surface of a club head, the weight of the club head is increased and simultaneously the center of gravity is biased to the outside of the club head, and when the protective film  10  is attached to the heel formed on the inner surface of a club head, the weight of the club head is increased and simultaneously the center of gravity is biased to the inside of the club head. 
     Accordingly, the attachment position of the protective film  10  is adjusted in the process of head fitting for increasing weight by attaching the protective film  10  to a club head in accordance with a swing path that a user has taken to through repeated swings and a corresponding flying path of a golf ball, thereby reducing generation of a slice that is generated when a golf ball is hit with a club head open or a hook that is generated, reversely, when a golf ball is hit with a club head closed. 
     Further, when the protective film  10  is attached to the crown formed on the top of a club head, the weight of the club head is increased and simultaneously the center of gravity is moved upward in the club head, and when the protective film  10  is attached to the sole formed on the bottom of a club head, the weight of the club head is increased and simultaneously the center of gravity is moved downward in the club head, thereby reducing an excessive down blow or side blow. 
     As described above, the head fitting film for club head protection of the present invention is closely and firmly attached to the outer surface of a club head in a bonding type, thereby not only preventing the club head from being scratched or damaged, but also adjusting the weight and the center of gravity of the club head quickly, simply, and finely through selective attachment. Accordingly, there is an effect that it is possible to satisfy all of the athletic ability, taste, preference, feeling of hit, etc. of each user. 
     Further, since it is possible not only to reduce generation of a slice or a hook, but also to improve carry through effective fitting of weight and a center of gravity, there is an effect that the present invention helps improve the ability of golf. 
     Further, since head fitting is quickly and simply made, the convenience of head fitting is greatly improved and simultaneously head fitting is possible at a low cost, so there is an effect that economic efficiency is excellent. 
     Further, since the head fitting film for club head protection of the present invention can be easily fabricated in various sizes or designs, it can be produced as various kinds of products in accordance with the shapes of the club heads of various golf clubs such as a driver, a wood, an iron, and a putter, whereby there is an effect that it is possible to increase a commercial value by producing products corresponding to various golf clubs depending on users. 
       FIG.  3    is a protective film perspective view according to a second embodiment of a head fitting film for club head protection of the present invention, and  FIG.  4    is a protective film use state view according to the second embodiment of a head fitting film for club head protection of the present invention. 
     A head fitting film for club head protection is described with reference to  FIGS.  3  to  4   , but a detailed description of components having repeated configuration and same reference numerals as the embodiment described above will be omitted. 
     The protective film  10  may further have a cut groove  101  at the edge. 
     That is, at least one or more cut grooves  101  are formed at the edge of the protective film  10 , so the protective film  10  can be more closely attached to the surface of a club head by adjusting the opening of the cut grooves  101  along the curve of the surface of the club head in the process of attaching the protective film  10  to the surface of the club head. 
     The cut groove  101  has straight portions  101   a and a curved portion  101   b.    
     The straight portions  101   a are formed at both sides of the cut groove  101  to be connected to the opening of the cut groove  101 . 
     The curved portion  101   b is formed to connect the straight portions  101   a at both sides inside the straight portions  101   a.    
     Accordingly, when the opening of the cut groove  101  is adjusted in accordance with the curve of the surface of a club head in the process of attaching the protective film  10  to the surface of the club head, it is possible to prevent the inside of the cut groove  101  from coming off even though the opening of the cut groove  101  is adjusted by the curved portion  101   b.    
       FIG.  5    is a use state cross-sectional view according to a third embodiment of a head fitting film for club head protection of the present invention. 
     A head fitting film for club head protection is described with reference to  FIG.  5   , but a detailed description of components having repeated configuration and same reference numerals as the embodiment described above will be omitted. 
     The protective film  10  may further include a weight sheet  40 . 
     It would be preferable that the weight sheet  40  is formed in a smaller size than the protective film  10  to have a thickness of 1 mm or less and weight of 1 to 4 g using a metal sheet, or a rubber sheet, an urethane sheet, or a carbon sheet mixed with metal powder and is attached to the inner surface of the protective film  10  so that the weight and center of gravity of a club head are more easily adjusted, but it should be noted that the present invention is not limited thereto. 
     Further, it is preferable that weight is printed or embossed or engraved on the surface of the weight sheet  40 . 
     Accordingly, the weight sheet  40  has weight that makes it possible to easily adjust weight for head fitting using a size and a thickness smaller than those of the protective film  10 , so it is possible to more easily and quickly perform head fitting by selectively attaching the weight sheet  40 . 
     Further, the weight sheet  40  may be stacked in multiple layers. 
     In this case, it is preferable that a bonding layer  401  is further provided between the weight sheets  40  stacked in multiple layers. 
     Accordingly, the amount of stacking of the weight sheet  40  is adjusted by selectively attaching/detaching the weight sheet  40  stacked through the bonding layer  401  in head fitting, weight is more easily adjusted. 
       FIG.  6    is a use state cross-sectional view according to a fourth embodiment of a head fitting film for club head protection of the present invention. 
     A head fitting film for club head protection is described with reference to  FIG.  6   , but a detailed description of components having repeated configuration and same reference numerals as the embodiment described above will be omitted. 
     The protective film  10  may further include a forming wire  50 . 
     The forming wire  50  is inserted along the edge of the protective film  10  and it is preferable that the forming wire  50  is made of a metallic material. 
     Accordingly, when the forming wire  50  is bent in accordance with the surface shape and the curvature of a club head in the process of attaching the protective film  10  to the surface of the club head, the edge of the protective film  10  in which the forming wire  50  is inserted is maintained in the shape bent by the forming wire  50  as the forming wire  50  is bent in accordance with the surface shape and the curvature of the club head, whereby the attached state of the protective film  10  that is attached to the surface of the club head is more firmly maintained. 
     Further, the forming wire  50  is made of a metallic material having strength higher than that of the protective film  10 , whereby even if the protective film  10  is partially damaged due to contact between the ground and the club head having the protective film  10  attached thereto, direct contact of the ground with the club head is prevented by the forming wire  50  positioned on the surface of the club head, so it is possible to more effectively prevent the club head from being scratched or damaged. 
     Embodiments of the present invention are not implemented by only the devices and/or operation methods described above, and may be implemented through programs for achieving functions corresponding to the configuration of embodiments of the present invention, or recording media in which the programs are recorded, and the present invention may be easily achieved by those skilled in the art from the embodiments described above.
