     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0032]    Referring to  FIGS. 1 and 2 , a preferred embodiment of a slide bracket of the present invention includes a bracket ( 1 ), a locating holder ( 2 ), a hanging block ( 3 ), a retaining member ( 4 ), a spring ( 5 ), and a resilient member ( 6 ). 
         [0033]    The bracket ( 1 ) is provided with an end plate ( 11 ) and an opening ( 111 ) is provided on the end plate (I  1 ). One or a plurality of opening ( 111 ) may be disposed depending on the mounting of the bracket ( 1 ). As illustrated, two openings ( 111 ) are provided on the bracket ( 1 ). A pair of pivoting tags ( 12 ) each provided with an axial hole ( 121 ) is disposed on the bracket ( 1 ) and a pin ( 13 ) is disposed to penetrate through the pair of pivoting tags ( 12 ). A limiting member ( 14 ) is disposed on the back of the end plate ( 11 ) and a retaining plate ( 15 ) is disposed near the pair of pivoting tags ( 12 ). 
         [0034]    The locating holder ( 2 ) is connected to the front of the end plate ( 11 ) of the bracket ( 1 ) and contains two chambers ( 21 ) corresponding to the number of the opening ( 111 ) as illustrated. 
         [0035]    The hanging block ( 3 ) includes a first post ( 31 ) and a second post ( 32 ) connected to each other. The first post ( 31 ) is made in the form of square (or cylindrical, but not illustrated). The second post ( 32 ) is made in a cylindrical form. The first post ( 31 ) of the hanging block ( 3 ) penetrates through the opening ( 111 ) of the bracket ( 1 ) into the chamber ( 21 ) of the locating holder ( 2 ) for the hanging block ( 3 ) to expand for movement. The spring ( 5 ) is inserted into the chamber ( 21 ) to function against the first post ( 31 ) of the hanging block ( 3 ) for it to automatically return: A flange ( 311 ) is disposed on the first post ( 31 ) to hold against the opening ( 111 ) of the bracket ( 1 ). 
         [0036]    The retaining member ( 4 ) is pivotally connected to the pivoting tags ( 12 ) of the bracket ( 1 ), and has a locking end ( 41 ) facing the back of the end plate (  11 ) of the bracket ( 1 ). The retaining member ( 4 ) is provided with the resilient member ( 6 ) which is a resilient plate having a clamping part ( 61 ) at one end to clamp on the retaining member ( 4 ) and a locating part ( 62 ) at the other end to hold against the retaining plate ( 15 ) disposed on the bracket ( 1 ) to provide return elasticity to the retaining member ( 4 ). 
         [0037]    The means for the retaining member ( 4 ) to be given with the return elasticity is not limited to that as described above. As illustrated in  FIG. 3 , a resilient member ( 6   a ) is a torsion spring containing a force-applying end ( 61   a ) to hold against the retaining member ( 4 ) and a locating end ( 62   a ) to hold against the retaining plate (( 15 ) on the bracket ( 1 ). 
         [0038]    Now referring to  FIG. 4 , in mounting the bracket to a support ( 9 ) provided with multiple of mounting holes ( 91 ) each made in a square form, the first post ( 31 ) of the hanging block ( 3 ) is inserted into the mounting hole ( 91 ) of the support ( 9 ) with the locking end ( 41 ) of the retaining member ( 4 ) holding against the support ( 9 ) while having the retaining member ( 4 ) and the end plate ( 11 ) of the bracket ( 1 ) to hold and secure the support ( 9 ). When adapted to a support ( 9 ′) provided with multiple round mounting holes ( 91 ′) as illustrated in  FIGS. 5  and  6 , the bracket ( 1 ) has the second post ( 32 ) of the hanging block ( 3 ) to be inserted into the round mounting hole ( 91 ′) of the support ( 9 ′) with the first post ( 31 ) of the hanging block ( 3 ) to automatically retract in the chamber ( 21 ) of the locating holder ( 2 ) and to compress against the spring ( 5 ) disposed in the chamber ( 21 ). 
         [0039]    In another preferred embodiment of the present invention as illustrated in  FIGS. 7 and 8 , a first post ( 31   a ) and a second post ( 32   a ) of a hanging block ( 3   a ) are designed such that allows both posts to be inserted to each other. The first post ( 31   a ) is disposed with an axial hole ( 312   a ) for the first post ( 31   a ) to receive insertion of the second post ( 32   a ). Meanwhile, the second post ( 32   a ) has its inner end to be connected to a locating holder ( 2   a ). A restraining ring ( 33   a ) is disposed in the axial hole ( 312   a ) of the first post ( 31   a ) to be inserted onto the second post ( 32   a ). A chamber ( 21   a ) of the locating holder ( 2   a ) contains a first spring ( 51   a ) and a second spring ( 52   a ) with the former functioning on the first post ( 31   a ) and the latter functioning on the restraining ring ( 33   a ). The first post ( 31   a ) is provided with a flange ( 311   a ) to hold against the opening ( 111 ) of the bracket ( 1 ). A gradation part ( 321   a ) is disposed to the second post ( 32 ) to relatively hold against the inner perimeter of the restraining ring ( 33   a ). Two tapered surfaces ( 313   a,    331   a ) are respectively disposed to the axial hole ( 312   a ) and the restraining ring ( 33   a ), and the circumference of the restraining ring ( 33   a ) is provided with axial slots ( 332   a ). 
         [0040]    As illustrated in  FIG. 9 , when adapted to the support ( 9 ) provided with multiple mounting holes ( 91 ) each made in a square form, the bracket ( 1 ) has the first post ( 31   a ) of the hanging block ( 3   a ) to be inserted into the mounting hole ( 91 ) of the support ( 9 ) and the retaining member ( 4 ) to hold against the support ( 9 ). To prevent the first post ( 31 .a) from being automatically retracted too easily so as to facilitate insertion into the mounting hole ( 91 ) of the support ( 9 ), the first post ( 31   a ) when being pushed against alone as illustrated in  FIG. 10 , the tapered surface ( 313   a ) of the first post ( 31   a ) will compress the tapered surface ( 331   a ) of the restraining ring ( 33   a ). Because the second spring ( 52   a ) is holding against the restraining ring ( 33   a ), the restraining ring ( 33   a ) provided with the slots ( 332   a ) is forced to retract inward when pushed by the tapered surface ( 313   a ) of the first post ( 31   a ); and the retaining ring ( 33   a ) in turn holds against the gradation part ( 321   a ) of the second post ( 32   a ) to restrict the first post ( 31   a ). 
         [0041]    When adapted to the support ( 9 ′) provided with multiple mounting holes ( 91 ′) with each made in a round form as illustrated in  FIG. 11 , the bracket ( 1 ) has the front section of the second post ( 32   a ) of the hanging block ( 3   a ) to be inserted into the mounting hole ( 91 ′) of the support ( 9 ′). As the hanging block ( 3   a ) is pushed in further towards the support ( 9 ′) as illustrated in  FIG. 12 , the restraining ring ( 33   a ) is first pushed and retracted to allow its end provided with the axial slots ( 332   a ) to penetrate through the gradation part ( 321   a ) of the second post ( 32   a ) and further into the hanging block ( 3   a ). As illustrated in  FIG. 13 , the first post ( 31   a ) of the hanging block ( 3   a ) is also pushed to retract by the support ( 9 ′) to allow the second post ( 32   a ) to be pushed even further into the mounting hole ( 91  ′) of the support ( 9 ′) while the retaining member ( 4 ) is also holding against the support ( 9 ′).
