Full Description:
BACKGROUND  
       [0001]     The invention relates to prying tools, and in particular, to prying tools separating engaged plastic objects efficiently.  
         [0002]     Liquid crystal displays (LCDs) are common electronic devices. Typically, plastic front and back covers of a LCD include corresponding engaging structures. The corresponding engaging structures are purposely designed such that the plastic front and back covers are engaged firmly. Thus, it may be difficult to separate the covers manually for replacement or repair.  
         [0003]     Usually, a flat screwdriver inserted between the plastic front and back covers is used to prize the plastic front and back covers. However, the plastic front and back covers can be damaged or deformed in this way, thus wasting time, efforts, and materials.  
       SUMMARY  
       [0004]     Prying tools are provided. A prying tool is used to separate engaged objects having a groove formed where the objects meet. An exemplary embodiment of a prying tool includes a pair of handles and a pair of prying slices. The pair of handles is interlaced and rotatably pivoting on each other. The pair of prying slices is disposed on the pair of handles respectively. The pair of prying slices can be partly inserted into the groove when tightly closed.  
         [0005]     Some embodiments of a prying tool include a pair of handles and a pair of prying slices. The pair of handles is interlaced and rotatably pivoting on each other. Each handle comprises a long arm portion and a short arm portion respectively on two sides of a pivot point on which the pair of handles pivots. The pair of prying slices is disposed on the pair of short arm portions respectively. The pair of prying slices can be partly inserted into the groove when tightly closed.

     DETAILED DESCRIPTION  
       [0012]     Prying tools are described in greater detail in the following.  
         [0013]     A principle aim of the invention is to provide a pair of prying slices on a pair of handles of a prying tool. The pair of handles is interlaced and rotatably pivoted on each other. After inserting the pair of prying slices into a groove of a liquid crystal display (LCD) where the plastic front cover and the plastic back cover meet, the plastic front cover and the plastic back cover thereof can be separated easily.  
         [0014]      FIG. 1   a  is a diagram of an embodiment of a prying tool  100 , wherein a pair of prying slices  102  is tightly closed.  FIG. 1   b  is a diagram of the prying tool  100 , wherein the pair of prying slices  102  is separated.  
         [0015]     The prying tool  100  includes a pair of handles  101 , a pair of prying slices  102 , and an elastic component  103 .  
         [0016]     The pair of handles  101  is interlaced and rotatably pivoted on each other. Each handle  101  includes a long arm portion  105  and a short arm portion  106  respectively on two sides of a pivot point  104  on which the pair of handles  101  pivots.  
         [0017]     The pair of prying slices  102  is disposed on the pair of short arm portions  106  respectively. Each prying slice  102  comprises a leading angle  107  (clearly shown in  FIG. 2   c  also).  
         [0018]     The elastic component  103  is a compression spring connected between the pair of long arm portions  105 .  
         [0019]     Moreover, the long arm portion  105  and the short arm portion  106  of each handle  101  and the corresponding prying slice  102  thereon are integral and made of metal.  
         [0020]     As shown in  FIG. 1   b,  when the pair of long arm portions  105  receives an external force  300 , the pair of prying slices  102  is separated.  
         [0021]     As shown in  FIG. 1   a,  when the external force  300  ceases, the elastic component  103  applies resilience on the pair of long arm portions  105  to tightly close the pair of prying slices  102 .  
         [0022]      FIG. 2   a  is a schematic diagram of the prying tool  100 , wherein the pair of prying slices  102  is inserted into a groove  203  of a liquid crystal display (LCD)  200 .  FIG. 2   b  is an enlarged diagram of a dotted-line portion A in  FIG. 2   a .  FIG. 2   c  is a cutaway view along a line B in  FIG. 2   a.    
         [0023]     The prying tool  100  can separate engaged objects, such as a plastic front cover  201  and a plastic back cover  202  of the LCD  200 .  
         [0024]     A groove  203  formed where the plastic front cover  201  and the plastic back cover  202  meet is about 1 mm in width.  
         [0025]     The pair of prying slices  102  of the prying tool  100  can be partly inserted into the groove  203  when tightly closed. Moreover, each prying slice  102  comprises the leading angle  107 , such that the pair of prying slices  102  can be inserted into the groove  203  more easily.  
         [0026]     When the pair of long arm portions  105  of the prying tool  100  receives the external force  300  (shown in  FIG. 1   b ), the pair of prying slices  102  is separated. Thus, the plastic front cover  201  and the plastic back cover  202  can be separated easily.  
         [0027]     Some embodiments of a prying tool utilize a pair of prying slices to separate a plastic front cover and a plastic back cover of a liquid crystal display (LCD) by inserting the pair of prying slices into a groove of the LCD where the plastic front cover and the plastic back cover meet.  
         [0028]     Some embodiments of a prying tool can be operated by a single hand to separate engaged objects conveniently and safely, avoiding damage or deformity.  
         [0029]     While the invention has been described by way of example and in terms of preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
