       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0072]      FIG. 1A  is a perspective view of one embodiment of the invention, and  FIG. 1C  is a perspective three-dimensional view of the invention. The user puts a communication apparatus  4  on a base  1 , then adjusts a right-side spacer  23  of a left-rotatory clamping arm  2  and a left-side spacer  33  of a right-rotatory clamping arm  3  to clamp the communication apparatus  4  by the left-rotatory clamping arm  2  and clockwise clamp arm  3 , according to the dimensions of the communication apparatus  4 . There is a direction control key  21  on the left-rotatory clamping arm  2 , and a Left key  22  on the upper side of the left-rotatory clamping arm  2 . There are a plurality of function keys  31 , comprising key A, B, C, D, on the right-rotatory clamping arm  3 , and the user can set these keys up according to different habits. And there is a Right key  32  on the right side of the right-rotatory clamping arm  3 , which enables the user to have another choice when setting up these function keys. There is a power switch  34  up the Right key  32 . There is a intelligent power indicating light  35  for indicating the user to change battery.  FIG. 1B  is another perspective view of one embodiment of the invention.  
         [0073]     Referring to  FIGS. 2A, 2B , and  2 C, when the user wants to user the apparatus of the invention, he needs to rotate the left-rotatory clamping arm  2  in 90 degree toward down direction, and to rotate the right-rotatory clamping arm  3  in 90 degree toward up direction, to move the arms away from the base  1 .  
         [0074]     If the user does not want to clamp the communication  4 , he can rotate the left-rotatory clamping arm  2  and the right-rotatory clamping arm  3  to maximum angle, then a fixing switch  81  springs out to fix the left-rotatory clamping arm  2  and right-rotatory clamping arm  3  in position. When the user presses the fixing switch  81 , he can release the fixed arms.  
         [0075]     Referring to  FIGS. 3A, 3B , and  3 C, when the user wants to draw in the apparatus of the invention, he takes the communication apparatus  4  out. Then he rotates the left-rotatory clamping arm  2  in 90 degree toward up direction, and rotates the right-rotatory clamping arm  3  in 90 degree toward down direction, to draw the arms in till the arms touch each other on the base  1 , which makes it convenient to be carried with the user.  
         [0076]     Referring to  FIG. 4 , when the user rotates the left-rotatory clamping arm  2  toward down direction, or rotates the right-rotatory clamping arm  3  toward up direction, it drives a left gear  71  or a right gear  72 . There are two linkages  7  and a recovering spring  9  linking the left gear  71  and the right gear  72 , which make the arms move in symmetrical mode. By the linkage  7 , the arms rotate in same angle and relative same position, and the recovering spring  9  will be pulled.  
         [0077]     When the user strongly rotates the left-rotatory clamping arm  2  or the right-rotatory clamping arm  3 , a buffer mechanism  5  reduces the strength and protect the apparatus from being damaged. When the user rotates the left-rotatory clamping arm  2  and right-rotatory clamping arm  3  to proper position, he can pull the fixing switch  6  to make a stop mechanism  61  touch the gear with an element, then fix the left-rotatory clamping arm  2  and right-rotatory clamping arm  3 .  
         [0078]     If the user does not want to clamp the communication  4 , he can rotate the left-rotatory clamping arm  2  and the right-rotatory clamping arm  3  to maximum angle, then a fixing switch  81  springs out to fix the left-rotatory clamping arm  2  and right-rotatory clamping arm  3  in position. When the user presses the fixing switch  81 , he can release the fixed arms.  
         [0079]     When the user wants to draw in the apparatus of the invention, he rotates the left-rotatory clamping arm  2  in 90 degree toward up direction, and rotates the right-rotatory clamping arm  3  in 90 degree toward down direction, to drive the left gear  71  and right gear  72  and draw the arms into proper position by the recovering spring  9  on the linkage  7 .  
         [0080]      FIG. 5  is a perspective view of structure of the invention. A battery  9  provides power via a DC/DC converter  10 . Then the power is delivered to a multipoint control unit  11 , and a wireless circuitry module  13 . When an input apparatus  12  transmits a control signal to the multipoint control unit  11 , the multipoint control unit  11  transmits the control signal to the wireless circuitry module  13 . The wireless circuitry module  13  then transmits the control signal to the communication apparatus  4  via an antenna  14 .  
         [0081]      FIG. 6  is a corresponding flow chart between hardware and software of the invention. It starts from processing  
         [0082]     “ 100  installing driving program”,  
         [0000]     then it goes to  
         [0083]     “ 101  judging if the installation were successful or not”,  
         [0000]     if not, it needs to reinstall driving program;  
         [0000]     if successful, it goes to  
         [0084]     “ 102  enabling the portable wireless control apparatus by the user”.  
         [0000]     After these, if it shows
