BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to an improved hair clip structure, mainly comprising a base plate which has an elastic middle bracket and an upper clipping plate at one end, and an elastic middle bracket and an upper clipping plate being coupled together the other end, and a first latching member and a second latching member being disposed at the position proximate to their coupling position, such that the curved surface at the middle section of the elastic middle bracket generates a more definite and significant curvature change by the fixing of the first latching member and the second latching member in position when the upper clipping plate and the base plate are clipped. 
     2. Description of the Related Art 
     Please refer to FIGS. 10 and 11 for the traditional hair clip, which includes a base plate  7 , an upper clipping plate  8  and a middle bracket  9 , and the number of hair clipped by the hair clip of this type depends on the only space that the upper clipping plate  8  and the base plate  7 . In addition, when the hair pushes the middle bracket  9 , both ends of the hair clip move sideways, and the middle section of the middle bracket  9  is lowered. Therefore, when the prior art hair clip is in use, the hair is clipped by means of the pressure between the middle bracket  9  and the upper clipping plate  8 . However, this kind of design suits better for the clipping lots of hair. When it comes to lesser hair, the pressure at the middle bracket  9  is not sufficient to hold the hair and let the hair clip fall out of the hair, and hence gives a poor clipping effect. 
     To resolve the above-mentioned shortcoming, an improved hair clip was invented, which is disclosed in the U.S. Pat. No. 4,976,277. The hair clip has a base  100 , and a corresponding bracket  101  being disposed at an end of the base  100 , and a hook  102  being extended inward is disposed on the bracket  101 , and a supporting frame  103  being disposed at the other end, and such supporting frame  103  has a corresponding coupling hole  104 , which is coupled to an upper plate  110 . An outwardly protruded axial section  111  is disposed on each of the both sides on an end of the upper plate  110 , and the axial section  111  just passes through the coupling hole  104  so that the other end of the upper plate  111  is capable of having the open and closed positions, and a curved elastic middle bracket  120  being disposed between the upper plate  110  and the base  100 . Both sides of an end of the elastic middle bracket  120  has a arc-shaped protruding ear  121  and a latching plate  122  being extended from the middle of the same end towards the protruding ear  121 , such that the end of the upper plate  110  having the axial section  111  can be embedded into the spaced formed by the protruding ear  121  and the latching plate  122 , and the elastic middle bracket  120  can swing within certain range by using the axial section  111  of the upper plate  110  as the center. Furthermore, the opposite end to where the upper plate  110  and the elastic middle bracket  120  are coupled has corresponding holes  112 ,  123  but not on the same plane. When it is used, it forms the latching holes  112 ,  123  with a height difference on different planes according to the quantity of hair, and selects one of the holes to latch onto the hook of the bracket  101 . It changes the curvature of the elastic middle bracket  120  to have an effect better than the above-mentioned hair clip. However, when the elastic middle bracket  120  is embedded into one end where the upper plate  110  and the base  100  are coupled, or directly coupled, with the upper plate  110  onto one end, the upper plate  110  is coupled with a movable method. Therefore, when the hair is clipped between the elastic middle bracket  120  and the upper plate  110 , the elastic middle bracket  120  will move to one end due to the pressure on the upper plate  110  and the pushing force of the hair, and hence it cannot clip the hair securely. It is not perfect for the use when the hair clip gradually falls off from the hair. 
     SUMMARY OF THE INVENTION 
     In view of the shortcomings and poor clipping effect of the traditional hair clip as described in the previous section, the inventor of the present invention based on years of experience in the related industry conducted extensive research to enhance the structure and design of the hair clip herein which is hereby submitted for patent application. 
     The primary objective of the present invention is to provide an improved hair clip structure, mainly comprising a base plate which has an elastic middle bracket and an upper clipping plate at one end, and a middle elastic bracket and an upper clipping plate being coupled together the other end, and a first latching member and a second latching member being disposed at the position proximate to their coupling position, such that the curved surface at the middle section of the elastic middle bracket generates a more definite and significant curvature change by the fixing of the first latching member and the second latching member in position when the upper clipping plate and the base plate are clipped, and further prevents the hair clip from being fallen off. 
     Another objective of the present invention is to provide an improved hair clip structure, wherein each side of the elastic middle bracket has at least one corresponding protruded section, and a plurality of interlaced bars are disposed between the protruded section of the elastic middle bracket, thereby when the hair clip is clipped, the bars will evenly distribute the hair in the protruded section to enhance the clipping effect.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The present invention discloses an improved hair clip structure. Please refer to FIGS. 1 and 2 which show the preferred embodiment of the present invention, and the structure comprises a base plate  1  having a corresponding pressing plate  11  each on both sides of the base plate  1 , and a latching hook  111  is freely extended inward and corresponding to the pressing plate  11 , and the corresponding coupling plate  12  being disposed on both sides at another end. The free end of the coupling plate  12  has a corresponding coupling hole  121 , and a corresponsive sliding groove  122  being disposed at the position where the coupling holes  121  and the base plate  1  are coupled. 
     In addition, an upper clipping plate  2  is disposed on the base plate  1 , and an axial section  21  being extended outward and disposed on both sides of an end of the upper clipping plate  2 . The axial section  21  just passes through the coupling holes  121 , so that it makes the upper clipping plate  2  and the base plate  1  being coupled together. A cylindrical member  22  is disposed at another end; the upper clipping plate  2  has a latching hole  23  next to the cylindrical member  22 ; and a first latching member  24  (which is a concavely bent section in this embodiment) is disposed next to the latching holes  23 . 
     Furthermore, an elastic middle bracket  3  is disposed between the upper clipping plate and the base plate  1 . A corresponsive sliding axis  31  is disposed on each of both sides of the elastic middle bracket  3 . The sliding axis  31  is embedded into the sliding groove  122  of the base plate  1  so that the sliding axis  31  can properly move in the sliding groove  122 . An arc-shaped elastic section  311  is extended outward and disposed at the end of the elastic middle bracket  3  proximate to the sliding axis  31 . When it is used, the elasticity of the arc-shaped elastic section  311  keeps the elastic middle bracket  3  at the highest position of the sliding groove  122 , and the other end has a cylindrical member  32  to work with the cylindrical member  22  of the upper clipping plate  2  such that end of the elastic middle bracket  3  having the cylindrical member  32  is transversally embedded into the cylindrical member  22  of the upper clipping plate  2 , and is coupled to the end of the upper clipping member having the cylindrical member. Further, a latching hole  33  is disposed on the elastic middle bracket  3  at the location proximate to the cylindrical member  32 , and the latching hole  33  is not on the same plane as that of the latching hole  23  on the upper clipping plate  2 . A first latching member  24  and a corresponding second latching member  34  are disposed next to the latching hole  33 , and the latching members are protruded sections for this embodiment. In addition, a concave arc-shaped press surface  35  is disposed at the middle section of the elastic middle bracket  3 . 
     Please refer to FIGS. 2,  3 , and  4 . When the hair clip is in use, we select to use a latching hook  111  of the pressing plate  11  on one end of the base plate  1  for passing through the latching hole  23  of the upper clipping plate  2  (as shown in FIG. 4) depending on how much hair are going to be clipped, or select the latching hole  33  (as shown in FIG. 3) to generate two different clipping gaps for the upper clipping plate  2  and the base plate  1 . When there is less hair, the latching hook  111  latches into a fixed position at the latching hole  23  of the upper clipping plate  2 , so that the concave arc-shaped press surface  35  of the elastic middle bracket  3  forms a larger curvature and generates a bigger clipping force. On the contrary, when there is more hair, the latching hook  111  latches into the fixed position at the latching hole  33  of the elastic middle bracket  3 , so that the concave arc-shaped press surface  35  of the elastic middle bracket  3  forms a smaller curvature to adopt and clip more hair in the hair clip. 
     Furthermore, when the upper clipping plate  2  and the base plate  1  are clipped together, the elastic middle bracket  3  by means of the elasticity of the arc-shaped elastic section  311  fixes one end of the sliding axis  31  into the highest position of the sliding groove  122 ; and by means of the positioning of the first latching member  24  and the second latching member  34 , it fixes the end where the elastic middle bracket  3  and the upper clipping plate  2  are coupled. When the elastic middle plate  3  is pressed, it will not slide back and forth along the base plate  1  such that the curvature change generated on the concave arc-shaped press surface  35  is more definite. 
     Further, please refer to FIGS. 5,  6 , and  7 , which show another embodiment of the elastic middle bracket  3  of the present invention, wherein a protruding section  351  (in the shape of a cone for this embodiment) is disposed at each of the lateral sides of the concave arc-shaped press surface  35  of the elastic middle bracket  3 . A hollow open groove is disposed between the protruding sections, and bars  352  which are interlaced with the protruding section  351  is disposed in the open groove. When the hair clip is clipped, the bars  352  evenly distribute the hair between the adjacent protruding sections  351  to enhance the clipping effect. In addition, a positioning convex plate  331  is formed on a side of the latching hole  33  of the elastic middle bracket  3  such that the cylindrical member  32  on one end of the elastic middle bracket  3  is transversally embedded into the coupling hole formed on the cylindrical member  22  at the end of the upper clipping plate  2 . When the elastic middle bracket  3  and the upper clipping plate  2  are clipped, the elastic middle bracket  3  can be fixed in position by inserting the positioning convex plate  331  into a side of the latching hole of the upper clipping plate  2 . 
     Furthermore, please refer to FIGS. 8 and 9, which show another preferred embodiment. The structure comprises a base plate  4  having a corresponding pressing plate  41  on both of its sides, and the free end of the pressing plates  41  has an inwardly extended and corresponding latching hook  411 , and both sides of another end has a corresponding coupling plate  42 , and the free end of the coupling plates  42  has a corresponding coupling hole  421 . A corresponding sliding groove  422  is disposed between the end where the coupling holes  421  of the coupling plate  42  and the base plate  4  are connected. 
     Additionally, the base plate  4  has an upper clipping plate  5 , and both sides of an end of the upper clipping plate  5  has an outwardly extended and corresponding axial section  51  which exactly passes through the coupling hole  421 , so that the upper clipping plate  5  can be coupled with the base plate  4 . A bent end  52  is disposed on the other end, and a latching hole  53  is disposed on the upper clipping plate  5  at the position proximate to the bent end  52 . A first latching member  54  (which is a large cylindrical member in this embodiment) is disposed next to the latching hole  53 . 
     Furthermore, an elastic middle bracket  6  is disposed between the upper clipping plate  5  and the,base plate  4 , and a corresponding sliding axis  61  is disposed on each of the both sides of an end of the elastic middle bracket  6 . The sliding axis  61  is just embedded into the sliding groove  422  of the base plate  4 , so that the sliding axis  61  can move properly in the sliding groove  422 . An outwardly extended arc-shaped elastic section  611  is disposed on an end of the sliding axis  61 . When the hair clip is in use, the elasticity of the arc-shaped elastic section  611  will keep the elastic middle bracket  6  at the highest position of the sliding groove  422 . The other end of the sliding axis  61  has an embedded end  62  which works together with the bent end  52  of the upper clipping plate  5 , such that the end having the embedded end  62  of the elastic middle bracket  6  can be transversally embedded into the bent end  52  of the upper clipping plate  5  and coupled to the end having the bent end  52  of the upper clipping plate  5 . Further, the elastic middle bracket  6  has a latching hole  63  at a position adjacent to the embedded end  62 , and the latching hole  63  is not on the same plane with that of the latching hole  53  on the upper clipping plate  5 . A first latching member  54  being disposed next to the latching hole  53  works together with a second latching member  64  (this embodiment uses a small cylindrical member). In addition, the middle section of the elastic middle bracket  6  have a wave-shaped press surface  65  such that when the elastic middle bracket  6  and the upper clipping bracket  5  are coupled, by means of the positioning effect of the first latching member  54  and the second latching member  64 , the elastic middle bracket  6  and the upper clipping plate  5  can be securely coupled. When the upper clipping plate  5  and the base plate  4  are coupled, the change of the wave-shaped press surface  65  at the middle section of the elastic middle bracket  6  is more definite and secure. 
     Please refer to FIGS. 8 and 9. When the hair clip is in use, the user can select to pass the latching hook  411  at the pressing plate  41  on one end of the base plate  4  into the latching hole  53  of the upper clipping plate  5 , or into the latching hole  63  of the elastic middle bracket  6 , such that the upper clipping plate  5  and base plate  4  generate two different clipping gaps. When there is less hair, the latching hook  411  can be hooked into the latching hole  53  of the upper clipping plate  5  so that the larger curvature formed at the wave-shaped press surface  65  of the elastic middle bracket  6  generates a larger clipping force. On the contrary, when there is more hair, the latching hook  411  can be hooked into the latching hole  63  of the elastic middle bracket  6  such that the wave-shaped arced surface forms a smaller curvature and completely clips all of the hair in it. 
     In addition, a blocking plate  423  is disposed at the rear side of the coupling plate  42  of the base plate  4  to restrict and block the arc-shaped elastic section  611  of the elastic middle bracket  6  in order to accomplish better effect. 
     In summation of the above description, the present invention herein enhances the performance than the conventional structure and further complies with the patent application requirements and is submitted to the Patent and Trademark Office for review and granting of the commensurate patent rights.
