The installation sequence of the three parts from bottom to top is rectangular coordinate motion device 1, polar coordinate motion device 2, spherical coordinate motion device 3. Rectangular coordinate motion device 1 is the basic device, which can mainly provide forward and backward movement and upward and downward movement, which mainly consists of base 101, locking screw 102, locking pressing sheet 103, vertical support 104, lifting lead screw 105 and locking large nut 106. The forward and backward movement mainly relies on the locking screw 102 connected between the vertical support 104 and the locking pressing sheet 103, and slides forward and backward in the sliding groove of the base 101 to realize the locking operation of the forward and backward movement. The upward and downward movement mainly relies on the rotation of the through hole in the middle of the rotating support hollow frame 203 on the lifting lead screw 105 to realize the upward and downward movement, and when the rotating support hollow frame 203 slides to the specified position, the rotating support hollow frame 203 is pressed by the upward and downward locking large nut 106 to realize the locking operation of the upward and downward movement. Polar coordinate motion device 2 is a transitional connecting device, which can mainly provide swing movement around the fixed point, which mainly consists of rotating shaft 201, swing adjusting screw 202 and rotating support hollow frame 203. The upward and downward swing movement mainly relies on the adjustment relationship between the upward swing adjusting screw 202 and the downward swing adjusting screw 202, so that the supporting spherical joint 301 rotates around the rotating shaft 201 installed on the rotating support hollow frame 203 and is position-locked. The upward swing adjusting screw 202 and the downward swing adjusting screw 202 are screw adjusted. Spherical coordinate motion device 3 is an end connecting antenna device, which can mainly provide multi-freedom fine adjustment movement, which mainly consists of supporting spherical joint 301 and spherical locking screw 302. The supporting spherical joint 301 is installed with an antenna on the end face, and the local position and posture of the antenna are adjusted by adjusting the position and posture of the supporting spherical joint 301, and after the position is reached, the position of the supporting spherical joint 301 is locked by the spherical locking screw 302, which is locked by screw thread. Through the superposition of various movements, the position and posture change of different antennas can be realized to meet the use requirements. As shown in Figure 1 The antenna device is respectively a first antenna 4 and a second antenna 5.

When the antenna needs to be switched, the rotating support hollow frame 203 is only needed to be rotated to switch the antenna.
