According to this embodiment, the front engagement means  45  is comprised of two beveled notches  451  bilaterally formed in the front side of the outer barrel member  402 .  
         [0024]     The resilient retaining rod  5  is mounted in the inner barrel member  401  of the locating barrel  4  and fixedly fastened to the rear side of the inner barrel member  401  with two screws  71 , comprising a transversely protruding front retaining portion  51  insertable into the longitudinal slot  42  of the inner barrel member  401  and a transversely protruding middle press portion  52 .  
         [0025]     According to this embodiment, the inner barrel member  401  of the locating barrel  4  has an opening  43  in the peripheral wall in line with the longitudinal slot  42  near the rear side. The outer barrel member  402  has an opening  44  in the peripheral wall corresponding to the opening  43  of the inner barrel member  401 . The middle press portion  52  of the resilient retaining rod  5  is insertable through the openings  43  and  44  to the outside of the locating barrel  4 . Further, the back holder shell  122  of the base  12  has a small through hole  125  corresponding to the middle press portion  52  of the resilient retaining rod  5 .  
         [0026]     The coupling barrel  3  has the front end thereof fixedly fastened to the display panel  11  between the front face panel  111  and the back cover  112 . According to this embodiment, the coupling barrel  3  has the front end terminating at a mounting plate  33  fixedly fastened to the front face panel  111  and the back cover  112  with screws  72 , and the rear end terminating at engagement means  31 .

The coupling barrel  3  further has a longitudinal slot  32  corresponding to the longitudinal slot  42  of the inner barrel member  401 .  
         [0027]     Referring to FIGS.  3 ˜ 5  and  FIGS. 1 and 2  again, when wishing to affix the display panel  11  to the base  12 , the coupling barrel  3  is sleeved onto the tubular body  41  of the inner barrel member  401  to force the protrusions  311  into the beveled notches  451  of the outer barrel member  402  and to prevent relative rotary motion between the coupling barrel  3  and the locating barrel  4 , allowing the transversely protruding retaining portion  51  of the resilient retaining rod  5  to engage into the longitudinal slot  42  of the inner barrel member  401  and the longitudinal slot  32  of the coupling barrel  3 . Therefore, the display panel  11  is locked to the base  12  as shown in  FIG. 5 .  
         [0028]     Referring to  FIG. 6  and  FIGS. 1 and 2  again, when wishing to remove the display panel  11  from the base  12 , a pointed object (see the arrowhead sign in  FIG. 6 ) is inserted through the small through hole  125  (see  FIG. 1 ) to force the middle press portion  52  of theresilient retaining rod  5  backward and to further disengage the front retaining portion  51  inserted into the longitudinal slot  32  of the coupling barrel  3  (see  FIG. 6 ), and then the coupling barrel  3  is removed from the locating barrel  4  to separate the display panel  11  from the base  12 . When wishing to separate the display panel  11  from the base  12 , the user must use a pointed object and insert it through the small through hole  125  to disengage the resilient retaining rod  5  from the coupling barrel  3 . This design can prevent the accidental disengagement of the retaining rod  5  from the coupling barrel  3 , such as by a child.  
         [0029]     In order to present reverse action of the resilient retaining rod  5  after the middle press portion  52  of the resilient retaining rod  5  has been forced backward, the user can rotate the coupling barrel  3  relative to the inner barrel member  401  through an angle, for example, 30° to stop one protrusion  311  against the front retaining portion  51  of the resilient retaining rod  5 , facilitating removal of the coupling barrel  3  from the locating barrel  4 .  
         [0030]     The aforesaid design of quick detachable bearing bracket is simple, cost effective and labor saving. After dismounting of the display panel  11  from the base  12 , the user can fasten the display panel  11  to the base  12  again in a different angular position.  
         [0031]      FIG. 7  is a perspective assembly view of the second embodiment of the present invention. This second embodiment is substantially the same as the aforesaid first embodiment with the exception that the locating barrel  811  of the quick detachable bearing bracket is formed integral with the base, referenced by  81 . The locating barrel  811  has the same structure as the locating barrel  4  of the aforesaid first embodiment. The base  81  can be hung on the wall, or stood on the top of a table. After disconnection of the display panel  11  from the locating barrel  811 , the display panel  11  can be fastened to the locating barrel  811  again in another angular position.  
         [0032]      FIG. 8  is a perspective assembly view of the third embodiment of the present invention. According to this embodiment, the base, referenced by  82 , has a mounting face  821  that can be affixed to a wall  6  for enabling the display panel  11  to be placed on the wall  6 .
