     DETAILED DESCRIPTION 
       [0010]    The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. 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. 
         [0011]    Referring to  FIGS. 1 and 2 , a test support apparatus in accordance with an embodiment is shown. The test support apparatus includes a base  10 , a support bracket  20  pivotally mounted to the base  10 , two securing clamps  30  secured to the support bracket  20 , two positioning arms  50 , and two positioning members  60 . In one embodiment, the test support apparatus is used fro clamping an expansion card  40 . 
         [0012]    The base  10  includes a base body  11  and two first pivot portions  13  extending from one side of the base body  11 . Each first pivot portion  13  defines a first pivot hole  131  in the free end of the first pivot portion  13 . In one embodiment, the base body  11  is rectangular. There is an obtuse angle between each first pivot portion  13  and the base body  11 . The base body  11  defines a first elongated sliding slot  111  passing through the base body  11 . 
         [0013]    The support bracket  20  includes a support panel  21  and two second pivot portions  23  extending from one side of the support panel  21 . In one embodiment, the support panel  21  is rectangular. There is an obtuse angle between each second pivot portion  23  and the support panel  21 . The support panel  21  defines two positioning holes  214 . Each second pivot portion  23  defines a second pivot hole  231  corresponding to the first pivot hole  131 . The support panel  21  defines a second elongated sliding slot  211  passing through the support panel  21 . Each clamp  30  defines a securing hole  31  corresponding to the positioning hole  214 . 
         [0014]    Two securing members  70  are used for securing the two clamps  30  to the support panel  21 . Each securing member  70  includes a securing shaft  71  and a securing nut  73 . The securing shaft  71  defines outer screws. The securing nut  73  defines inner screws for engaging the outer screws of the securing shaft  71 . Each positioning arm  50  defines an elongated positioning slot  51 . 
         [0015]    Each positioning member  60  includes a positioning shaft  61  and a positioning nut  63 . The positioning shaft  61  includes a head portion  611 , a shaft portion  613  extending from the head portion  611 , and a securing portion  615  extending from the shaft portion  613 . The securing portion  615  defines outer screws. The positioning nut  63  defines inner screws for engaging the outer screws of the positioning shaft  61 . 
         [0016]    Referring to  FIG. 2 , in assembly, the support bracket  20  is placed on the base  10  to enable the second pivot hole  231  to be aligned with the first pivot hole  131 . A pivot shaft  81  of a pivot member  80  passes through the second pivot hole  231  and the first pivot hole  131 . A pivot nut  82  of the pivot member  80  is screwed to the pivot shaft  81  to pivotally attach the second pivot portion  23  to the first pivot portion  13 . 
         [0017]    The positioning slot  51  of each positioning arm  50  is aligned with the first elongated sliding slot  111  of the base body  11  and the second elongated sliding slot  211  of the support panel  21 . The two positioning shafts  61  pass through the positioning slot  51  of one positioning arm  50 , the first elongated sliding slot  111 , and the second elongated sliding slot  211 , and then pass through the positioning slot  51  of the other positioning arm  50 . The two positioning nuts  63  are screwed to the two securing portions  615  of the two positioning shafts  61 , thereby securing the support bracket  20  to the base  10 . There is an angle defined between the support panel  21  and the base  10 . 
         [0018]    The two clamps  30  are placed on the support bracket  20  to enable the securing holes  31  of the clamps  30  to be aligned with the positioning holes  214  of the support panel  21 . The securing shafts  71  of the two securing members  70  pass through the securing holes  31  and the corresponding positioning holes  214 . The securing nuts  73  are screwed to the securing shaft  71  to enable the two clamps  30  to be movably attached to the support panel  21 . 
         [0019]    The securing nuts  73  are rotated along a first rotation direction to adjust the distance between the clamps  30  and the support panel  21  to receive the expansion card  40 . The securing nuts  73  are rotated along a second rotation direction substantially opposite to the first rotation direction to adjust the clamps  30  to resist the expansion card  40 . At this time, the expansion card  40  is sandwiched between the two clamps  30  and the support panel  21 . 
         [0020]    Referring to  FIGS. 3 and 4 , when the angle between the support panel  21  and the base  10 , needs to be adjusted, the positioning nuts  63  are rotated along a third rotation direction to enable the positioning shaft  61  to move in the first elongated sliding slot  111 , in the second elongated sliding slot  211 , or in the positioning slot  51 . Then the positioning nuts  63  are rotated along a fourth rotation direction substantially opposite to the third rotation direction to secure the positioning shaft  61  tightly, thereby changing the angle between the support panel  21  and the base  10 . 
         [0021]    It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
