Abstract:
A quick holder includes a bottom housing, a cover, two clamping members, and a tensile spring. The tensile spring is urged between the retaining posts of the two clamping members conveniently, so that the two opposite clamping members may be used to clamp the paper by a single tensile spring, thereby simplifying the whole structure, and thereby decreasing the difficulty of assembly.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a quick holder, and more particularly to a quick holder that may be assembled quickly, easily and conveniently, and has a simplified construction. 
     2. Description of the Related Art 
     A conventional holder in accordance with the prior art of which the applicant is aware is disclosed in U.S. Pat. No. 5,544,396, and is briefly shown in FIG.  1 . The conventional holder as shown in FIG. 1 comprises a base  80 , two clamping members  82  each pivotally mounted on the base  80 , and two springs (not shown) each having a first end secured on an inner wall of the base  80  and a second end secured on a lower end of each of the two clamping members  82 . Thus, the paper may be clamped by the two clamping members  82  by the elastic action of the two springs. However, it is necessary to mount each of the two springs between the inner wall of the base  80  and the lower end of each of the two clamping members  82 , thereby causing inconvenience and difficulty in assembly. In addition, the two clamping members  82  probably cannot be operated by the two springs in a synchronous manner, thereby affecting operation of the holder. 
     SUMMARY OF THE INVENTION 
     The present invention has arisen to mitigate and/or obviate the disadvantage of the conventional holder. 
     The primary objective of the present invention is to provide a quick holder that may be assembled quickly, easily and conveniently, and has a simplified construction. 
     Another objective of the present invention is to provide a quick holder, wherein the tensile spring is urged between the two opposite clamping members conveniently, so that the two opposite clamping members may be used to clamp the paper by a single tensile spring, thereby simplifying the whole structure, and thereby decreasing the difficulty of assembly. 
     In accordance with the present invention, there is provided a quick holder, comprising a bottom housing, a cover, two clamping members, and a tensile spring, wherein: 
     the cover is mounted on the bottom housing, and has a periphery formed with two radially opposite pin holes for passage of a combination pin; 
     each of the two clamping members is pivotally mounted on the combination pin, each of the two clamping members has a bottom respectively provided with a pivot ear pivotally mounted on the combination pin, the pivot ear of each of the two clamping members is extended rearward and is provided with a retaining post; and 
     the tensile spring is urged between the retaining posts of the two clamping members. 
    
    
     Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings and initially to FIGS. 2-4, a quick holder in accordance with a preferred embodiment of the present invention comprises a bottom housing  10 , a cover  20 , and two clamping members  30  and  40 . 
     The bottom housing  10  is an oblong or circular disk, and has an outer diameter substantially equal to an inner diameter of the cover  20 . The bottom housing  10  has an outer wall provided with a plurality of locking blocks  11 , and has a center formed with a through hole  12 . The quick holder further comprises a bottom disk  50  provided with a cone-shaped slit insertion head  501  inserted into the through hole  12  of the bottom housing  10 , so that the bottom disk  50  is secured on a bottom of the bottom housing  10 . Preferably, the bottom disk  50  has a bottom combined with a magnet  51 . Alternatively, the bottom disk  50  has a bottom combined with an adhesive plate  52 . Alternatively, the bottom disk  50  is made to have a sucker configuration. 
     The cover  20  is mounted on the bottom housing  10 , and has an inner wall formed with a plurality of locking holes  21 . Each of the locking blocks  11  of the bottom housing  10  is inserted into a respective one of the locking holes  21  of the cover  20 , so that the cover  20  is closely combined with the bottom housing  10 . The cover  20  has a top face formed with a circular through hole  22  for passage of the two clamping members  30  and  40 . The cover  20  has a periphery formed with two radially opposite pin holes  23  for passage of a combination pin  24 . 
     Each of the two clamping members  30  and  40  is pivotally mounted on the combination pin  24 . Each of the two clamping members  30  and  40  has an upper portion provided with an oblique guide face  31  and  41  and a mediate portion provided with a holding rib  32  and  42 . Each of the two clamping members  30  and  40  has a bottom respectively provided with a pivot ear  33  and  43  pivotally mounted on the combination pin  24 . The pivot ear  33  and  43  of each of the two clamping members  30  and  40  is extended rearward and is provided with a retaining post  34  and  44 . The quick holder further comprises a tensile spring  60  urged between the two opposite retaining posts  34  and  44  of the two clamping members  30  and  40 . 
     In assembly, the combination pin  24  is extended through the two radially opposite pin holes  23  of the cover  20 , and is extended through the pivot ear  33  and  43  of each of the two clamping members  30  and  40 , so that each of the two clamping members  30  and  40  is pivotally mounted on the cover  20 . In addition, the tensile spring  60  is urged between the two opposite retaining posts  34  and  44  of the two clamping members  30  and  40  conveniently. 
     Thus, the quick holder in accordance with the present invention may be assembled quickly, easily and conveniently, and has a simplified construction. 
     In operation, referring to FIGS. 4 and 5 with reference to FIGS. 2 and 3, the upper portions of the two clamping members  30  and  40  are in contact with each other by the tensile action of the tensile spring  60 , so that the holding ribs  32  and  42  of the two clamping members  30  and  40  are in contact with each other as shown in FIG.  4 . Then, a sheet of paper  1  may be inserted into the gap between the holding ribs  32  and  42  of the two clamping members  30  and  40  by guidance of the oblique guide faces  31  and  41  of the two clamping members  30  and  40  to press the two clamping members  30  and  40  to move outward and to compress the tensile spring  60 , so that the paper  1  may be clamped between the two clamping members  30  and  40 . After insertion of the paper  1 , the two clamping members  30  and  40  may be pushed to return to the original position by the restoring force of the tensile spring  60 , so that the paper  1  may be clamped between the holding ribs  32  and  42  of the two clamping members  30  and  40  as shown in FIG.  5 . 
     Although the invention has been explained in relation to its preferred embodiment as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
