Title: Hanging card mechanism for a socket

Description:
FIELD OF THE INVENTION  
      The present invention relates to a hanging card mechanism for a socket, and more particularly to a hanging card mechanism having two steps of the function of guarding against thief and an easier combination.  
     BACKGROUND OF THE INVENTION  
      Recently, a conventional hanging card, and particularly a hanging card for a socket, which is generally used on the market, only has basic function with hanging or decoration and has no the function which avoids stealing. Thus, when the hanging card and the socket are demonstrated, the socket could be pulled out and stolen by thief. For above reason, another hanging card is designed to have the function which avoids stealing. Although the mechanism of the hanging card has the function which can avoid stealing, there are the following disadvantages in an embodiment of the hanging card:  
      1. When the hanging card is joined with the socket, the hanging card must be align to the socket and further exactly joined with the socket so as to cause a user to be troublesome and inconvenient.  
      2. The movement of the hanging card corresponding to the socket is not smooth, and often the hanging card is incompletely snapped into the socket so as to cause the hanging card not to avoid stealing.  
      3. There is only one step of function of guarding against thief. When the hanging card is cut, the hanging card is only discarded and not recovered against, so as to cause the problem of environmental protection and waste the nature resource.  
      Accordingly, there exists a need for a hanging card mechanism for a socket to solve the above-mentioned disadvantages.  
     SUMMARY OF THE INVENTION  
      It is an object of the present invention to provide a hanging card mechanism having two steps of the function of guarding against thief and an easier combination and improving disadvantages of the conventional hanging card.  
      In order to achieve the foregoing objects, the present invention provides a hanging card mechanism for a socket. The socket is joined with the hanging card mechanism. The hanging card mechanism has two steps of the function of guarding against thief and includes a card body and a base. The card body includes a card having a bottom, a driving head expanding from the bottom of the card, and an inclined conical portion connected to the driving head. The base is circular and groove-shaped and includes a bottom, two snapping pieces disposed at the bottom and being symmetrical to each other, an inner bottom surface, and a groove disposed the inner bottom surface, such that the inclined conical portion of the driving head is inserted into and joined with the groove.  
      The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      Referring to FIGS.  1  to  6 , they depict a hanging card mechanism  10  for a socket  50  according to the present invention, wherein the hanging card mechanism  10  has two steps of function of guarding against thief and the bottom of the hanging card mechanism  10  is connected to the socket  50 . The present invention is characterized as follows:  
      The hanging card mechanism  10  includes a card body  20  and a base  30 . The card body  20  includes a card  21 , a driving head  25  which is expanding from the bottom of the card  21 , and an inclined conical portion  22  which is connected to the driving head  25 . The base  30  is circular and groove-shaped and includes two snapping pieces  31  which are disposed at the bottom thereof and symmetrical to each other. The base  30  is provided with a groove  32  which is disposed the inner bottom surface thereof, such that the inclined conical portion  22  of the driving head  25  is inserted into and joined with the groove  32 .  
      Furthermore, the diving head  25  is provided with at least one setting piece  26  which is deposed at two sides thereof, and the base  30  provided with at least one hole  33  which is corresponding to the setting piece  26 , such that the setting piece  26  is snapped into and joined with the hole  33 .  
      In addition, the snapping piece  31  of the base  30  is provided with at least one flange  34  so as to be snapped into and joined with the groove (not shown) which is disposed in the socket  50 .  
      Furthermore, the base  30  is provided with a block  25  which is disposed beside the groove  32 , and the driving head  25  is provided with a half arc groove  27  which is disposed in the bottom thereof, such that the block  25  and the half arc groove  27  are interactive to drive the hanging card mechanism  10  to be opened or closed.  
      Referring to FIGS.  1  to  6  again, they depict the combination of the hanging card mechanism  10  for the socket  50  according to an embodiment of the present invention. As the inclined conical portion  22  is inserted into the base  30 , the setting piece  26  of the driving head  25  will be snapped into and jointed with the base  30  so as to have a first step of the function of guarding against thief. Furthermore, after the inclined conical portion  22  is inserted into the groove  32  of the base  30 , the snapping piece  31  provided with the flange  34  will be pushed outward and then the flange  34  will be snapped into a groove (not shown) which is disposed in the interior of the socket  50  and corresponding to the flange  34 , so as to has a second step of the function of guarding against thief and be not pulled out by external force. Then, the combination of the hanging card mechanism  10  and the socket  50  are completed.  
      As described above, the hanging card mechanism  10  according to the present invention has two steps of the function of guarding against thief. When the socket  50  is requested to separated from the hanging card mechanism  10 , an A portion of the base  30  will be cut firstly. After the A portion is cut, the block  35  will be corresponding to the half arc groove  27  to be rotated so as to drive the inclined conical portion  22 . When the inclined conical portion  22  is rotated to 90 degrees, the inclined conical portion  22  does not push the snapping piece  31  and the flange  34  is reset to original position. Simultaneously, the flange  34  is not snapped into the groove of the socket  50 , such that the socket  50  will be separated from the snapping piece  31  of the base  30  and pulled out to be used. The base  30  and the socket  50  are closed, as shown in  FIG. 5 , and the base  30  and the socket  50  are opened, as shown in  FIG. 6 .  
      Furthermore, the advantage of the present invention is that the hanging card mechanism  10  does not need to be discarded after the socket  50  is separated from the hanging card mechanism  10 . Thus, the hanging card mechanism  10  differs from the conventional hanging card. Although the function of guarding against thief disappear when the A portion of the base  30  is cut, the hanging card mechanism  10  can be still used because the main structure of the hanging card mechanism  10  is not broken yet. The hanging card mechanism  10  can be still joined with the socket  50  and hanged by using the hanging card  21 , so the present invention solves the problem of environmental protection and economizes the nature resource.  
      In addition, as compared with the conventional hanging card, the hanging card mechanism according to the present invention has not only two steps of the function of guarding against thief but also an easier combination and an operation with less force. The shape of the hanging card mechanism is graceful, the structure of the hanging card mechanism is firm, and the hanging card mechanism can be recovered and used again to avoid buying a new one, such that a consumer can decrease the cost of the hanging card.  
      As a whole, the hanging card mechanism according to the present invention improves the driving method of the conventional hanging card and therefore the present invention has utility, the function of guarding against thief and non-obviousness.  
      Although the invention has been explained in relation to its preferred embodiment, it is not used to limit the invention. It is to be understood that many other possible modifications and variations can be made by those skilled in the art without departing from the spirit and scope of the invention as hereinafter claimed.
