   The present invention provides the sucking disc  12  at the bottom of the seat  10  to attach to the plane surface of an object. Thus the fixing mount according to the present invention is fixed at the surface of the object to use. The sucking disc  12  is disengaged from the surface of the object when the fixing mount is not in use. 
   The horizontal rotary device  20  according to the present invention is used to adjust the horizontal angle. Referring to  FIGS. 6 and 7 , when the horizontal rotary device  20  is rotated, the cogs  111  of the gear section  11  push the projections  212  of the elastic pieces  211  towards the hollow gap  210 . When the projection  212  is rotated to a place between two cogs  111 , the deformed elastic piece  211  returns to its original state and the projection  212  engages with two cogs  111 . The elastic pieces  211 , the projections  212  and the cogs  111  of the gear section  11  interact each other to reach an appropriate horizontal angle. 
   The pitch-adjusting device  30  of the present invention is used to adjust the pitch angle. Referring to  FIGS. 9 ,  10 A and  10 B, when the pitch-adjusting device  30  is in a stationary state, the first positioning pole  382  is inserted into the first positioning fixation hole  311  at the side of the pitch-adjusting seat  31 . When the first pressing element  36  is pressed inward, the bolt  35  pushes the first positioning unit  38  outward and the first positioning pole  382  moves out of the first positioning fixation hole  311 . The pitch-adjusting seat  31  is then free to rotate around the bolt  35  to adjust the pitch angle of the pitch-adjusting device  30 . When an appropriate angle is reached, release the first pressing element  36 . The first elastic unit  37  returns to its original state and pushes the first pressing element  36  outward. Then the bolt  35  pulls the first positioning unit  38  inward and the first positioning pole  382  is inserted into one of the first positioning fixation hole  311  at the side of the pitch-adjusting seat  31 . Therefore, the pitch-adjusting device  30  is fixed at a stationary state and an appropriate pitch angle. 
   The swing-adjusting device  40  of the present invention can adjust the swing angle freely, whose rotating axis is orthogonal to the rotating axis of the pitch-adjusting device  30 . Referring to  FIGS. 12 ,  13 A and  13 B, when the swing-adjusting device  40  is in a stationary state, the second positioning pole  462  is inserted into the second positioning fixation hole  411  at the side of the swing-adjusting seat  41 . When the second pressing element  44  is pressed inward, the fastening pin  43  pushes the second positioning unit  46  outward. The second positioning pole  462  on the second positioning unit  46  moves out of the second positioning fixation hole  411 . The swing-adjusting seat  41  is then free to rotate around the fastening pin  43  to adjust the swing angle of the swing-adjusting device  40 . When an appropriate angle is reached, release the second pressing element  44 . The compressed second elastic unit  45  returns to its original state and pushes the second pressing element  44  outward. Then the fastening pin  43  pulls the second positioning unit  46  inward and the second positioning pole  462  is inserted into one of the second positioning fixation hole  411  at the side of the swing-adjusting seat  41 . Therefore, the swing-adjusting device  40  is fixed at a stationary state and an appropriate swing angle. 
   A communication equipment such as mobile phone, PDA, GPS, etc is mounted on the platform of the equipment seat  42  of the swing-adjusting device  40  and locked into the equipment assembly hole  421  of the equipment seat  42 .
