Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Technical Field 
         [0002]    The present invention relates to pliers for fastening a male element and a female element of a button on a piece of cloth. More particularly, the disclosed pair of button pliers is configured to hold the male and female elements with improved retaining seats and snap them together. 
         [0003]    2. Description of Related Art 
         [0004]    A pair of conventional button pliers as shown in  FIG. 1  and  FIG. 2  typically has its jaw members provided with a first retaining seat  6  and a second retaining seat  7 . The first retaining seat  6  includes a first pressing segment  61  while the second retaining seat  7  includes a second pressing segment  71 . The first pressing segment  61  has a central concave surface and the second pressing segment  71  includes a circular concave portion  711  that provides the second pressing segment  71  with a centripetally inclined surface. Thereby, when a male element  41  and a female element  42  of a button are placed in the first pressing segment  61  and the second pressing segment  71 , respectively, an operator can squeeze the pliers and thus snap the male and female elements  41 ,  42  to fabricate the button. However, as shown in  FIG. 2 , due to the central concave surface of the first pressing segment  61 , the male button element  41  only contacts a small area of the first pressing segment  61 , but not fits close with the first pressing segment  61 . Furthermore, due to the circular concave portion  711  of the second pressing segment  71 , the centripetally inclined surface only allows the second pressing segment  71  to contact a periphery of a fixing socket  421  of the female button element  42 , and hinders the female button element  42  from fitting close with the second pressing segment  71 , causing an interval  72  between the female button element  42  and the second pressing segment  71 , as shown in  FIG. 3  and  FIG. 4 . As a result of the above fitting problems, when fixing pins  411  of the male button element  41  come into contact with the fixing socket  421  of the female button element  42 , impact therebetween may possibly happen, and when the fixing pins  411  lodge in the fixing socket  421 , both the fixing pins  411  and the fixing socket  421  receive insufficient supporting force, causing the fixing pins  411  unable to fully enter the fixing socket  421 , as shown in  FIG. 5 , rendering unsecured combination of the resultant button. 
       SUMMARY OF THE INVENTION 
       [0005]    In view of the shortcomings of the prior art device, the present invention provides a pair of button pliers with improved retaining seats. The pair of pliers has two jaw members provided with a first retaining seat and a second retaining seat, respectively. Therein, the first retaining seat includes a first coupling segment and a first pressing segment. The first coupling segment is connected with one said jaw member of the pliers and the first pressing segment has a circular groove for fittingly receiving a male button element. The second retaining seat has a second coupling segment and a second pressing segment. The second coupling segment is connected with thither jaw member of the pliers, and the second pressing segment has a circular block for supporting a female button element. Thereby, when the jaw members of the pliers are squeezed, the first retaining seat and the second retaining seat come close to each other, so that the circular groove and the circular block of the pressing segments make the male and female elements combine into a whole button. 
         [0006]    The primary objective of the present invention is to provide the forgoing button pliers, wherein the circular groove and the circular block facilitate increasing contacting areas between the male button element and the first pressing segment , and between the female button element and the second pressing segment , so that the male and female elements are allowed to fit close with the first pressing segment and the second pressing segment , thereby the male and female elements can be firmly combined when the first retaining seat and the second retaining seat are brought to each other.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0017]    Referring to  FIG. 6 , the present invention provides a pair of button pliers with improved retaining seats. The pair of button pliers  10  is equipped with the retaining seats, namely a first retaining seat  20  and a second retaining seat  30 . 
         [0018]    As shown in  FIG. 6  and  FIG. 7 , the pliers  10  has a first jaw member  11  and a second jaw member  12 , which are provided with the first retaining seat  20  and the second retaining seat  30 , respectively. The first retaining seat  20  includes a first coupling segment  21  and a first pressing segment  22 . Therein, the first coupling segment  21  is screwedly coupled with the first jaw member  11  of the pliers  10 , while the first pressing segment  22  extends from the first coupling segment  21  toward the first jaw member  11 . The second retaining seat  30  includes a second coupling segment  31  and a second pressing segment  32 . Therein, the second coupling segment  31  is screwedly coupled with the second jaw member  12  of the pliers  10 , while the second pressing segment  32  extends from the second coupling segment  31  toward the second jaw member  12 . Furthermore, the first pressing segment  22  and the second pressing segment  32  are sleeved by elastic pads  221 ,  321 , respectively. The elastic  . pads  221 ,  321  serve to not only position a male element  41  and a female element  42  of a button for preventing the first pressing segment  22  and the second pressing segment  32  from coming off, but also act as buffers when the first retaining seat  20  and the second retaining seat  30  are snapped together for preventing the first retaining seat  20  and the second retaining seat  30  from mutual impact or attrition. 
         [0019]    Referring to  FIG. 8 , the first pressing segment  22  includes a, whose inner diameter is sized to fittingly match an inner diameter of the male button element so that the circular groove  23  can fitly receive the male button element  41 . In addition, the circular groove  23  circles an accommodating space  231 . 
         [0020]    The second pressing segment  32  has a circular block  33  for being received in the accommodating space  231  and serving to position a female button element  42 . The circular block  33  has a circular convex surface and a recess  331  extending along an axis of the second coupling segment  31  so as to match the contour of the female button element  42 . 
         [0021]    Particularly, the circular convex surface of the circular block  23  contacting the female button element  42  may be a circular portion having a top surface in the shape of flat inclined plane, concave inclined plane, or convex inclined plane. The circular block  23  in another shape may be used as long as it provides the circular convex surface to close fit the female button element  42 . 
         [0022]    In this embodiment, as shown in  FIG. 8  and  FIG. 9 , a piece of cloth  50  on which the button is to be installed is placed between the first retaining seat  20  and the second retaining seat  30 . Then, when the first retaining seat  20  and the second retaining seat  30  are brought together, the first pressing segment  22  and the male button element  41  contact right at a position corresponding to where an arc of the circular groove  23  is formed so that the male button element  41  is allowed to fit close with the first pressing segment  22 . Meantime, the second pressing segment  32  and the female button element  42  are such contacting the a inclined surface of the fixing socket  421  close abuts upon the circular block  33  so that the female button element  42  fits close with the second pressing segment  32 . Thereby, owing to the support from the circular groove  23  and the circular block  33  of the first and second pressing segments  22 ,  32 , when piercing through the cloth  50  and contacting the fixing socket  421  of the female button element  42 , the fixing pins  411  of the male button element  41  are forced to curl along a profile of the fixing socket  421 , thereby causing the male and female elements  41 ,  42  combined as a whole piece, as shown in  FIG. 10  and  FIG. 11 . 
         [0023]    The present invention has been described with reference to the preferred embodiment and it is understood that the embodiment is not intended to limit the scope of the present invention. Moreover, as the contents disclosed herein should be readily understood and can be implemented by a person skilled in the art, all equivalent changes or modifications which do not depart from the concept of the present invention should be encompassed by the appended claims.
