The resilient retainer ( 86 ) is provided with two retaining feet ( 861 ) corresponding to the top and bottom of the wedging base ( 84 ′) at the rear end of the outer track ( 83 ). A retaining surface ( 862 ) is disposed on the end of each of the retaining feet ( 861 ). 
         [0040]    To assemble the preferred embodiment in practical use as illustrated in  FIG. 5 , the slide assembly ( 8 ) is separately incorporated with a front bracket ( 91 ) and a rear bracket ( 92 ). The front bracket ( 91 ) and the rear bracket ( 92 ) are mounted to supports ( 93 ), respectively. The two mounting members ( 5 ) respectively disposed on both ends of the main body ( 1 ) are connected to the slide assembly ( 8 ). As illustrated in  FIGS. 6 and 7 , the front arm ( 11 ) of the main body ( 1 ) is inserted by means of the mounting member ( 5 ) into the folded edges ( 841 ) of the wedging base ( 84 ) disposed at the rear end of the inner track ( 81 ) and holds against the retaining bits ( 842 ); meanwhile, the engaging button ( 7 ) on the mounting member ( 5 ) is inserted into and holds against the retaining piece ( 843 ) of the wedging base ( 84 ) by means of the bolt ( 72 ). Similarly, the rear arm ( 12 ) of the main body ( 1 ) is inserted by means of the mounting member ( 5 ) into the wedging base ( 84 ′) disposed at the rear end of the outer track ( 83 ); the mounting member ( 5 ) inserts through the folded edges ( 841 ′) of the wedging base ( 84 ′) to hold against the retaining bits ( 842 ′); and the engaging button ( 7 ) on the mounting member ( 5 ) has the bolt ( 72 ) to hold against the retaining piece ( 843 ′) of the wedging base ( 84 ′) to secure the mounting member ( 5 ) in position. As illustrated in  FIG. 8 , one end of the support frame ( 2 ) slides in the outer track ( 83 ) by means of the support block ( 3 ) connected to the inner rod ( 22 ) of the support frame ( 2 ); the other end of the support frame ( 2 ) is connected by insertion to the locating member ( 85 ) disposed at the rear end of the middle track ( 82 ) by means of the support locking member ( 4 ) connected to the outer rod ( 21 ) of the support frame ( 2 ) as illustrated in  FIG. 9 ; and the engaging button ( 7 ) on the support locking member ( 4 ) has the bolt ( 72 ) inserted into the through hole ( 851 ) of the locating member ( 85 ) as illustrated in  FIG. 7 . 
         [0041]    Upon placing the support block ( 3 ) into the outer track ( 83 ) as illustrated in  FIG. 10 , the support block ( 3 ) is inserted into the rear end of the outer track ( 83 ) so that the protruding bit ( 33 ) of the support block ( 3 ) compresses against and passes through the retaining feet ( 861 ) of the resilient retainer ( 86 ). Once the support block ( 3 ) passes through the resilient retainer ( 86 ) and the support block ( 3 ) moves backward, the support block ( 3 ) is prevented from falling off the outer track ( 83 ) since it will be stopped on the retaining surface ( 862 ) of each of the retaining feet ( 861 ) by means of the protruding bit ( 33 ). To remove the support block ( 3 ) as illustrated in  FIG. 11 , have the support block ( 3 ) to retreat to the retaining surface ( 862 ) of each retaining foot ( 861 ) for both press portions ( 32 ) to correspond to both retaining feet ( 861 ); meanwhile, by holding down both press portions ( 32 ) of the support block ( 3 ) for them to hold against both retaining feet ( 861 ) thus to release the protruding bit ( 33 ) of the support block ( 3 ) from both retaining surfaces ( 862 ) of the retaining feet ( 861 ) for removing the support block ( 3 ) out of the rear end of the outer track ( 83 ). 
         [0042]    According to the preferred embodiment, when the cable management arm operates by following pull and stretch of the slide assembly as illustrated in  FIG. 12 , the front arm ( 11 ) of the main body ( 1 ) and the support locking member ( 4 ) connected to the outer rod ( 21 ) of the support frame ( 2 ) will be displaced by following pull and stretch of the inner track ( 81 ) and the middle track ( 82 ); and the support block ( 3 ) connected to the other end of the support frame ( 4 ) through the inner rod ( 22 ) slides freely on the outer track ( 83 ). Meanwhile, both the outer rod ( 21 ) and the inner rod ( 22 ) of the support frame ( 2 ) will be pulled and stretched out and the support frame ( 2 ) inclines to a certain angle; the middle arm ( 13 ) of the main body ( 1 ) slides for a certain distance on the support frame ( 2 ) through the sleeve ( 14 ); and the sleeve ( 14 ) turns for a certain angle in relation to the middle arm ( 13 ). Consequently, as illustrated in  FIG. 13 , when both the inner track ( 81 ) and the middle track ( 82 ) are completely stretched out at different angle, the front arm ( 11 ) and the rear arm ( 12 ) of the main body ( 1 ) practically indicate a straight line to have the largest space and distance for stretching out. Meanwhile, the sleeve ( 14 ) located in the middle of the main body ( 1 ) slides from one end of the support frame ( 2 ) close to the support block ( 3 ) to another end of the support-locking member ( 4 ) close to the support locking member ( 4 ).
