           [0009]      FIG. 6  is a cross-sectional view of  FIG. 5 , taken along the line VI-VI, showing the plug fixing apparatus in a locking state. 
           [0010]      FIG. 7  is similar to  FIG. 6 , but showing the plug fixing apparatus in an unlocking state. 
       
    
    
     DETAILED DESCRIPTION 
       [0011]    The disclosure, including the accompanying drawing, is illustrated by way of examples and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
         [0012]      FIG. 1  and  FIG. 2  illustrate an exemplary embodiment of a plug fixing apparatus for fixing a plug  12  of a power cord  10  to a socket  32  of a power supply  30 . The plug fixing apparatus comprises a locking member  50  and a screw  70 . The plug  12  comprises a connecting portion  14  at one side. 
         [0013]      FIG. 1  and  FIG. 4  illustrate that the power supply  30  defines a sliding slot  34  above the socket  32 , and comprises a receiving portion  34   a  inside the power supply  30  bounding the sliding slot  34 . The receiving portion  34   a  includes a spring  342  and a sliding member  344  which is connected to a distal end of the spring  342  and slidable up and down inside the receiving portion  34   a.  A screw hole  346  is defined in the sliding member  344 . 
         [0014]    The locking member  50  comprises a fixing piece  52 , a supporting piece  54  vertically extending outward from a bottom of the fixing piece  52 , and a blocking piece  56  vertically extending down from a distal of the supporting piece  54  and parallel to the fixing piece  52 . The fixing piece  52  defines a fixing hole  520  adjacent to the supporting piece  54 . A distal end of the blocking piece  56  away from the supporting piece  54  forms a blocking portion  58 . The blocking portion  58  is an arc-shaped opening. 
         [0015]    The power supply  30  is fixed in a chassis  100 . The chassis  100  comprises a top board  102  covering the power supply  30 . A folding piece extends from the top of the chassis  100 . The folding piece defines a through hole  110 . The top board  102  defines a through hole  104  aligning with the through hole  110 . The chassis  100  defines an opening for allowing the power supply  30  to pass through. 
         [0016]      FIG. 3  and  FIG. 4  illustrate that in assembly, a top of the fixing piece  52  is aligned with the through holes  110  and  104 . The screw  70  extends through the fixing hole  520  and the sliding slot  34  and engages in the screw hole  346 , to fasten the locking member  50  to the sliding member  344 . 
         [0017]    Referring to  FIG. 5  through  FIG. 7 , upwardly push the locking member  50  to compress the spring  342 , the top of the fixing piece  52  extends through the through holes  110  and  104 . Insert the plug  12  of the power cord  10  into the socket  32  of the power supply  30 , release the locking member  50 , the locking member  50  slides down by the restoring force of the spring  342 , and the connecting portion  14  of the power cord  10  is locked in the blocking portion  58  of the locking member  50 , thereby the power cord  10  is fixed to the power supply  30 . The blocking portion  58  engages with the connecting portion  14  of the power cord  10 , and prevents the power cord  10  from loosening from the power supply  30 . 
         [0018]    To pull out the plug  12  from the socket  32 , upwardly push the locking member  50 , the top of the fixing piece  52  extends through the through holes  110  and  104  to make the locking member  50  disengage from the connecting portion  14 . Thereby, the power cord  10  can be detached from the power supply  30 . 
         [0019]    It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
