Four retaining portions  43 , two posts  45  inserted into the two sliding slots  313 , a protrusion  46  accommodated in the accommodating portion  315  are disposed on the inner surface of the enclosure  40 . Each retaining portion  43  includes a jointing piece  431  and three ribs  435  arranged one side of the jointing piece  431 . In one embodiment, the jointing piece  431  is L-shaped, and a space  436  is defined in the jointing piece  431 . A screw hole  461  is defined in the protrusion  46 , corresponding to the fixing hole  3151  of the accommodating portion  315 . Three screw holes  47  are defined in the enclosure  40 , corresponding to the three fixing holes  314  of the main body  31 . 
     Referring to  FIGS. 3-4 , in assembly, the pivot piece  33  of the mounting member  30  passes through the hole  41 , from the inside to the outside of the enclosure  40 , and is located on the bottom of the hole  41 . The retaining portion  43  is accommodated in the first portion  3112  of the positioning slot  311 , and the ribs  435  of the retaining portion  43  abut the edge of the positioning slot  311 . The post  45  is located an upper end of the sliding slot  313 , and the protrusion  46  is received in an upper end of the accommodating portion  315 . The mounting member  30  is pulled upwards, and the pivot piece  33  is slid upwards in the hole  41  until the retaining portion  43  is accommodated in the second portion  3114  of the positioning slot  311 ; the ribs  435  of the retaining portion  43  abut the edge of the second portion  3114 , the post  45  is located a lower end of the sliding slot  313 ; and the protrusion  46  is received in a lower end of the accommodating portion  315 . Therefore, the stopper portion  312  is engaged in the space  436  of the enclosure  40 , and the post  45  is located at a down end of the sliding slot  313 . The protrusion  46  is located at a down end of the accommodating portion  315 . The four fixing holes  314 ,  3151  are aligned with the four screw holes  47 ,  461 . Four fixing members  60  are inserted into the four fixing holes  314 ,  3151  and the four screw holes  47 ,  48 , to secure the mounting member  30  to the enclosure  40 . 
     Each wear washer  23  abuts the outside of each side panel  215 , and the positioning portion  235  of the wear washer  23  is engaged in the notch  2155 . Each engaging member  22  abuts each wear washer  23 . Each pivot piece  33  abuts the engaging member  22 , the catch  223  of the engaging member  22  is positioned in the indentation  335 , and the block  2112  of the hinge  20  abuts the cambered surface  333 . Each resistance washer  25  abuts inside of each side panel  215  of the hinge  20 , and the two fastening pieces  253 ,  255  are inserted into the clipping hole  2153  and the notch  2155 . The resistance washer  26  and the rubber washers  27 ,  28  in turn abut the resistance washer  25 . The fixing holes  221 ,  231 ,  251 ,  261 ,  271 ,  281  are aligned with the through hole  2151  of the side panel  215  and the pivot hole  331 , a fastening component  70  is screwed into the fixing holes  221 ,  231 ,  251 ,  261 ,  271 ,  281 , the through hole  2151 , and the pivot hole  331 , and the mounting member  30  is thus secured to the hinge  20 . The pivot piece  33  can be rotated between a first position and a second position. In the first position, the positioning portion  2112  of the hinge  20  is located in a first end of the cambered surface  333  of the mounting member  30 , and a first acute angle is formed between the connecting panel  213  of the hinge  20  and the main body  31 . In the second position, the positioning portion  2112  of the hinge  20  is located in a first end of the cambered surface  333  of the mounting member  30 , and a second acute angle less than that of the first acute angle is formed between the connecting panel  213  and the main body  31 . 
     The mounting panel  211  of the hinge  20  is placed on the panel  11 . The mounting holes  2114  of the mounting panel  211  are aligned with the securing holes  112  of the panel  11 . Two securing components  50  are inserted into the mounting holes  2114  and the securing holes  112 , and the hinge  20  is thus secured to the support  10 . 
     Referring to  FIG. 5 , when the viewing angle of the display (not shown) secured the enclosure  40  needs to be adjusted, the mounting member  30  can be rotated and positioned in any position between the first and second positions. The engaging members  22 , the wear washers  23 , the resistance washers  25 ,  26 , and the rubber washers  27 ,  28  produce friction on the fastening component  70  and the pivot pieces  33 .
