         [0025]    With reference to  FIGS. 2-4 , the base assembly  10  comprises a base  11  with a hollow supporting column  110  disposed at the center thereof and having a column recess  111  on a sidewall of the supporting column  110 . The base assembly  10  further comprises a base cap  12  having a base opening at a side surface and covering on the base  11 . A first toothed portion  120  is provided on the top surface of the base cap  12  and arranged in circularly and horizontal. The base assembly  10  further comprises a suction disk  13  made of a tenacious material. The suction disk  13  is provided with a disk arm  130  extended upward at the center of the suction disk  13 . Upper section of the disk arm  130  has a pinhole  131 . A base spring  14  is installed around the disk arm  130 . The base assembly  10  further comprises a positioning pin  16  and a locking tab  15  having two lugs  150 . Each of the lugs  150  has a lughole  151  and a projection  152  under the lug  150 . The disk arm  130  is installed into the supporting column  110  from the bottom of the base  11  through the base spring  14 . The positioning pin  16  pivotally joints with the supporting column  110 , the disk arm  130  and the locking tab  15  through the lugholes  151 , the column recess  111  and the pinhole  131 . When the suction disk  13  is placed on a plane surface and the locking tab  15  is flicked to a first position (flicked downward), the projections  152  is pressed on the base  11  and the disk arm  130  is raised upward by the lugs  150 . Accordingly, the suction disk  13  is sucked on the plane surface due to the negative pressure between the bottom of the suction disk  13  and the plane surface. Otherwise, the projections  152  disengage from the base  11  when the locking tab  15  is flicked to the second position (flicked upward). The disk arm  130  moves downward by the lugs  150  to release the suction disk  13  from the plane surface. 
         [0026]    The horizontal rotating assembly  20  of the present invention comprises a rotating base  21  with two stop member connecting parts  210 , having two first elastic members  211  telescoped thereby. At least one elastic piece  26  is disposed on the bottom of the rotating base  21 . The horizontal rotating assembly  20  connects to the base cap  12  by inserting a connecting screw  25  into a connecting bar  24 , the rotating base  21  and then the top of the base cap  12 . A rotating cap  22  comprises a cap opening  224  at the center, two cap recesses  221  and two cap holes  220 , and connects with the rotating base  21  by a cap-fixing pin  222 . Two stop members  23  are telescoped to the stop member connecting parts  210  on the rotating base  21  by passing through the cap recesses  221  of the rotating cap  22 . The stop members  23  move along an axial direction of the rotating base  21 . 
         [0027]    The first angle adjusting assembly  30  comprises a first angle adjusting base  31  having a second angle adjusting assembly recess  34  on the top surface thereof, a second toothed portion  310  on the bottom surface thereof, and a cavity  311  and a cavity  312  disposed on the opposite side thereof. The teeth of the second toothed portion  310  are arranged in a direction parallel to a rotation axis of the first angle adjusting assembly  30 . Two through holes  313  and  314  are arranged in the cavities  311  and  312  respectively. The first angle adjusting assembly  30  connects with the horizontal rotating assembly  20  by a connecting part  32  and a first screw  33 . 
         [0028]    The second angle adjusting assembly  40  of the present invention comprises a second angle adjusting base  41  having a third toothed portion  410  disposed circularly on both side surfaces thereof and connects with the second angle adjusting assembly recess  34  of the first angle adjusting assembly  30  by a second screw  44 , a second elastic member  45 , and positioning members  42  and  43 . 
         [0029]    As show in  FIG. 5 , the positioning pin  16  connects the suction disk  13 , the base  11  and the locking tab  15  by passing through the lugholes  151  of the locking tab  15 , the column recess  111  on the supporting column  110  and the pin hole  131  on the disk arm  130 . The suction disk  13  is in contact with the ground when the locking tab  15  is in the second position (as show in  FIG. 6A ). The suction disk  13  is disengaged from the surface plane. When the locking tab  15  is pressed to the first position (as show in  FIG. 6B ), the projections  152  are pressed on the base  11 , the positioning pin  16  drives the disk arm  130  upward, and the disk arm  130  pull the center of the suction disk  13  upward. There is a negative pressure between the suction disk  13  and the plane surface. Thus the fixation device sucks on the plane surface. 
         [0030]    As shown in  FIG. 7A , the rotating base  21  connects to the base assembly  10  by the connecting bar  24  and the connecting screw  25 . As shown in  FIGS. 7B and 8 , the horizontal rotating assembly  20  is rotatable along the central axis of the base assembly  10  after the rotating base  21  connects to the base assembly  10 . The elastic pieces  26  and the first toothed portion  120  are engaged thereby ensuring the horizontal rotating assembly  20  stops at the desired position. 
         [0031]    As shown in  FIG. 9 , the first angle adjusting assembly  30  connects with the horizontal adjusting assembly  20  by the connecting part  32  and the first screw  33 . The stop members  23  are disposed at a lateral surface of the horizontal rotating assembly  20 . The stop members  23  move along the axial direction of the rotating base  21  and are pushed back to an initial position by the first elastic members  211  when they are released. As shown in  FIGS. 10A and 10B , the second toothed portion  310  disengages from the stop members  23  when the stop members  23  move downward to leave the initial position. Therefore, the angle of the first angle adjusting assembly  30  is adjustable. The stop members  23  engage with the second toothed portion  310  of the first angle adjusting base  31  when the first elastic members  211  push the stop member  23  back to the initial position. Thus, the angle of the first angle adjusting assembly  30  is fixed. Lower part of the first angle adjusting assembly  30  is a cylindrical structure. A cylindrical axis is the rotation axis of the first angle adjusting assembly  30  and is perpendicular to the central axis of the base assembly  10 . 
         [0032]    As shown in  FIGS. 11 ,  12 A and  12 B, the second angle adjusting base  41  of the second angle adjusting assembly  40  is disposed in the second angle adjusting assembly recess  34  of the first angle adjusting assembly  30  by the second screw  44 , the second elastic member  45  and the positioning members  42  and  43 . The positioning member  42  moves outward with the second screw  44  when the positioning member  43  is pressed. The position member  42  disengages from the third toothed portion  410 . Therefore, the second angle adjusting assembly  40  is free to rotate as shown in  FIG. 12B . The positioning member  42  is pushed back to its initial position and engaged with the third toothed portion  410  by the second elastic member  45  when the positioning member  43  is released. Lower part of the second angle adjusting assembly  40  is a cylindrical structure. A cylindrical axis is the rotation axis of the second angle adjusting assembly  40  and is perpendicular to the rotation axis of the first angle adjusting assembly  30 . 
         [0033]    As mentioned, the fixation device described above with the communication equipments installed on the second angle adjusting assembly  40  is sucked on a surface by the suction disk  11  of the base assembly  10 . The rotation of the horizontal rotating assembly  20 , the first angle adjusting assembly  30  and the second angle adjusting assembly  40  achieves the purposes for user&#39;s ergonomics, habits and the convenient operation. 
         [0034]    Although the present invention has been described with reference to the preferred embodiment thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
