     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIGS. 1 and 2, an adjustable apparatus holder is used in a carrier, for example, a tough leather pocket (not shown), and adapted to hold an apparatus (PDA, pocket computer, mobile telephone, or any of a variety of personal electronic apparatus, not shown). The adjustable apparatus holder comprises a flat base panel  1 , a first side plate  2 , a second side plate  3 , and a locking mechanism  4 . 
     The base panel  1  comprises a first (bottom) surface  11 , a second (top) surface  12  opposite to the first (bottom) surface  11 , a bottom receiving space  10  defined by the first (bottom) surface  11  between the flat raised middle part and two relatively lower side parts of the base panel  1 , a plurality of mounting holes  13  extended through the first (bottom) surface  11  and the second (top) surface  12  and symmetrically disposed at two sides for mounting, a plurality of first short cylindrical protruded portions  14  and a plurality of second short cylindrical protruded portions  15  perpendicularly downwardly projected from the first (bottom) surface  11  and suspended in the bottom receiving space  10 , a first side  16 , and a second side  17  disposed in parallel to the first side  16 . Through the mounting holes  13 , the base panel  1  can be fixedly secured to a carrier (not shown) by fastening elements, for example, screws. The direction passing across the first side  16  and the second side  17  is defined as the extension direction of the adjustable apparatus holder. 
     The first side plate  2  is an angled plate comprising a horizontal wall  21  inserted into the bottom receiving space  10  of the base panel  1 , and a vertical wall  22  extended from one side of the horizontal wall  21  at right angles and disposed corresponding to the first side  16  of the base panel  1 . The horizontal wall  21  has two elongated sliding slots  211  bilaterally arranged in parallel and respectively coupled to the first short cylindrical protruded portions  14  of the base panel  1  for enabling the first side plate  2  to be moved relative to the base panel  1  in the aforesaid extension direction, a middle opening  212  extended to one side thereof away from the vertical wall  22 , and two serrated engagement portions  213  arranged in parallel at two sides of the middle opening  212  and extended in the aforesaid extension direction. 
     The second side plate  3  comprises a plate body  33 , a barrel  31  integrated with the bottom side of the plate body  33 , and a male connecting member, for example, a bottom plug rod  32  perpendicularly extended from the periphery of the barrel  31  in the direction opposite to the plate body  33 . A pivot  311  pivots the barrel  31  to the second side  17  of the base panel  1  by a pivot  311 . Two torsional springs  312  are sleeved onto the pivot  311 , each having two opposite ends respectively stopped at the plate body  33  and the base panel  1  to hold the second side plate  3  in a vertical position substantially in parallel to the vertical wall  22  of the first side plate  2 . 
     The locking mechanism  4  is provided in the middle opening  212  of the first side plate  2  within the bottom receiving space  10  of the base panel  1 . The locking mechanism  4  comprises a link  41  and two engagement blocks  42 . The link  41  comprises a female connecting member, for example, a plughole  411  disposed in one end (namely, the front end) and fastened to the male connecting member (the bottom plug rod)  32  of the second side plate  3 , and two side openings  412  disposed at two sides near the other end (namely, the rear end) for receiving the engagement blocks  42 . Each of the engagement blocks  42  comprises a plurality of oblique sliding slots  421  respectively coupled to the second short cylindrical protruded portions  15  of the base panel  1 , and a serrated engagement portion  422  adapted to engage the serrated engagement portions  213  of the first side plate  2  respectively. The oblique sliding slots  421  extend obliquely at an angle relative to the extension direction of the adjustable apparatus holder. 
     Referring to FIGS. 3 and 4, after installation of the adjustable apparatus holder in a carrier (not shown), the second (top) surface  12  of the base panel  1 , the vertical wall  22  of the first side plate  2  and the plate body  33  of the second side plate  3  can hold an electronic apparatus firmly in the carrier. When the plate body  33  of the second side plate  3  is kept in the vertical position (perpendicular to the base panel  1 ), the engagement blocks  42  are respectively bilaterally forced outwards from the link  41 , keeping the serrated engagement portions  422  of the engagement blocks  42  in engagement with the serrated engagement portions  213  of the first side plate  2 , and therefore the first side plate  2  is locked, i.e., the distance between the vertical wall  22  of the first side plate  2  and the plate body  33  of the second side plate  3  is fixed. 
     Referring to FIG.  5  and FIG. 3 again, when the plate body  33  of the second side plate  3  is tilted from the second side  17  of the base panel  1 , the bottom plug rod  32  of the second side plate  3  pushes the link  41  backwards (in the direction from the second side  17  of the base panel  1  toward the first side  16  thereof), thereby causing the engagement blocks  42  to be respectively received within the side openings  412  to disengage the serrated engagement portions  422  from the serrated engagement portions  213  of the first side plate  2 , for enabling the first side plate  2  to be moved relative to the base plate  1  to adjust the pitch between the vertical wall  22  of the first side plate  2  and the plate body  33  of the second side plate  3  according to the size of the electronic apparatus to be held. After loading of the electronic apparatus, the second side plate  3  is released from the hand, and the torsional springs  312  pull the second side plate  3  back to its former vertical position, and therefore the engagement blocks  42  are returned into engagement with the serrated engagement portions  213  of the first side plate  2  again. 
     A prototype of adjustable apparatus holder has been constructed with the features of FIGS.  1 ˜ 5 . The adjustable apparatus holder functions smoothly to provide all of the features discussed earlier. 
     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
