The multiple square holes 24 are respectively defined through the multiple second protrusions 23, and each square hole 24 has a square outline.
With reference to FIGS. 1 to 4, the satellite antenna 30 is threaded to the top surface of the second plate 21 by bolts. The second plate 21 is disposed between the satellite antenna 30 and the first plate 11. The satellite antenna 30 has a radome 31 for receiving electronic components of the satellite antenna 30.
With reference to FIGS. 1 to 4, each of the adjusting assemblies 40 has a linkage unit 41 and a knob 42. The linkage unit 41 is a bolt and has a threading section and a bolt head. The threading section of the linkage unit 41 is mounted through the second plate 21. The bolt head and the threading section of the linkage unit 41 are isolated from the second plate 21. The bolt head of the linkage unit 41 abuts against the top surface of the second plate 21. The first plate 11 is disposed between the second plate 21 and the knob 42. The knob 42 is screwed with the threading section of the linkage unit 41 and abuts against the bottom surface of the second plate 21. The four adjusting assemblies 40 surround the abutting protrusion 22 of the second tray 20 and are disposed adjacent to an edge of the second plate 21.

With reference to FIGS. 7 to 10, in the second embodiment of the present invention, each of the adjusting assemblies 40 also has the linkage unit 41 and the knob 42. The first and the second embodiments have the following differences. The linkage unit 41 of each adjusting assembly 40 has a first threading section 412 and a second threading section 413. A thread of the first threading section 412 and a thread of the second threading section 413 are oriented in opposite directions. The knob 42 is disposed at a middle section of the linkage unit 41, between the first threading section 412 and the second threading section 413, and has multiple grooves formed in a circumferential surface of the knob 42.
Furthermore, with reference to FIGS. 7 to 10, in the second embodiment, each of the adjusting assemblies 40 further has a first mount 43 and a second mount 44. The first mount 43 is connected to the first plate 11 and has a universal end 431 and a first threading hole 432 respectively disposed at two opposite ends of the first mount 43. The universal end 431 and the first threading hole 432 are isolated from each other by the first plate 11. The universal end 431 abuts against the bottom surface of the first plate 11 and is a cone gradually tapered toward the first plate 11. The second mount 44 is fixed to the bottom surface of the second plate 21, extends toward the first plate 11, and has a second threading hole 441.
With reference to FIGS. 7 to 10, the first threading section 412 and the second threading section 413 of each adjusting assembly 40 are respectively threaded in the first threading hole 432 of the first mount 43 and the second threading hole 441 of the second mount 44.
With reference to FIGS. 11 and 12, when the knob 42 of at least one adjusting assembly 40 is spun, the first plate 11 and the second plate 21 are pulled close to each other via the adjusting assembly 40, and the orientation of the satellite antenna 30 mounted to the second plate 21 is adjusted as well.
With reference to FIGS. 11 and 12, in the second embodiment, each adjusting assembly 40 may further have two nuts 45 respectively screwed with the first threading section 412 and the second threading section 413 of the linkage unit 41 of the adjusting assembly 40. After the orientation of the satellite antenna 30 is adjusted, the two nuts 45 can be spun and respectively abut against the first mount 43 and the second mount 44 for fixing the first mount 43 and the second mount 44 to make sure that the orientation of the satellite antenna 30 cannot be changed spontaneously.
With reference to FIGS. 3, 4, 9, and 10, in the first embodiment and the second embodiment, the level instrument 50 is connected to the second plate 21.
