[0042] As an optional embodiment, refer to Figure 3 and Figure 5 When the support assembly 21 and the rotating assembly 22 are assembled, the fourth annular boss 223 is inserted into the mating groove 214, while the first annular boss 212 is limited between the third annular boss 222 and the fourth annular boss 223 to improve the accuracy of the relative rotation of the support assembly 21 and the rotating assembly 22. The center hole of the support assembly 21 and the center hole of the rotating assembly 22 are simultaneously connected to the pin 26. The setting of the pin 26 avoids the relative movement of the support assembly 21 and the rotating assembly 22 in the axial direction. The mounting plates at both ends of the pin 26 are respectively placed in the clearance grooves opened on the corresponding side of the support plate 211 and the clearance grooves opened on the corresponding side of the rotating plate 221 to prevent the mounting plates at both ends of the pin 26 from interfering with other components.

The connecting edge of the guide cylinder 122-2 is welded to the upper part of the first rotating rod 122-1. The guide cylinder 122-2 extends along the length of the first rotating rod 122-1. When the first driving rod 122 is assembled with the first guide rod 121, the guide cylinder 122-2 is fitted onto the outside of the upper first guide rod 121. The cooperation between the guide cylinder 122-2 and the first guide rod 121 is used to guide the movement direction of the first rotating rod 122-1 and to prevent deformation of the first rotating rod 122-1 during movement.

The scale 28 is adapted to the reference line 29 printed or engraved on the side wall of the connecting plate 27. Before use, the reference line 29 is aligned with the zero point of the scale 28, with the zero point located in the middle of the scale 28. During use, the tilt angle of the connecting plate 27 is determined by the offset of the reference line 29.

[0055] Reference Figure 8 This embodiment provides a positioning device, including the aforementioned angle adjustment mechanism, as well as a moving part 3 and a fixed base 4; a connecting plate 27 is disposed on the moving part 3, and the moving part 3 is used to move the connecting plate 27 in the horizontal and vertical directions. The moving part 3 is disposed on the fixed base 4, and the fixed base 4 is configured as an electromagnetic base, which facilitates the assembly and disassembly of the fixed base 4 from the position to be measured; furthermore, an anti-slip layer is added to the bottom of the fixed base 4, and when the electromagnetic base does not need to be opened for fixation, the anti-slip layer can prevent the fixed base 4 from sliding at the position to be measured.

[0056] The moving component 3 includes a horizontal moving assembly 31, which includes a first guide block 311. A first guide post 313 and a first lead screw 314 are respectively disposed through the first guide block 311. The first guide post 313 is symmetrically arranged on both sides of the first lead screw 314. The arrangement of the first guide post 313 provides guidance and support for the movement of the first guide block 311. A first mounting plate 312 is fixedly connected to both ends of the first guide post 313. The first mounting plate 312 is fixed to both sides of the top surface of the fixed base 4.

[0057] One end of the first lead screw 314 passes through one of the first mounting plates 312, and a first hand crank 315 is fixedly connected to the through end. Shaking the first hand crank 315 can make the first lead screw 314 rotate synchronously, thereby driving the first guide block 311 to move back and forth along the first lead screw 314.

[0058] The vertical moving component 32 includes a second guide block 321, the side of which is bolted to the support plate 211.

[0059] The second guide block 321 has a second guide post 323 and a second lead screw 324 respectively passing through it. The second guide post 323 is symmetrically arranged on both sides of the second lead screw 324. The arrangement of the second guide post 323 provides guidance and support for the movement of the first guide block 311. The two ends of the second guide post 323 are respectively provided with second mounting plates 322. The second mounting plate 322 located at the bottom is fixedly connected to the top surface of the first guide block 311.

[0060] The top end of the second lead screw 324 passes through the top second mounting plate 322, and the through end of the second lead screw 324 is fixedly connected to the second hand crank 325. Shaking the second hand crank 325 can make the second lead screw 324 rotate synchronously, thereby driving the second guide block 321 to move up and down along the second lead screw 324.

[0061] When using the device, first place it in the preset installation position, then move the horizontal moving component 31 to the front and the vertical moving component 32 to the lowest zero position, align the baseline 29 with the zero point of the scale 28, and finally place the transmitting antenna on the connecting plate 27 to complete the preparation work before use.

[0062] During testing, the transmitting and receiving antennas are connected. If the signal received by the receiving antenna determines that the transmitting antenna's position is offset from the required installation position, the horizontal moving component 31 is moved to the required position, and then the vertical moving component 32 is moved to the required position. The screw 225 is loosened, and the first rotating rod 122-1 and the second rotating rod 132 are simultaneously turned downwards or upwards. The first rotating rod 122-1 or the second rotating rod 132 pushes the driving block 224, causing the connecting plate 27 to rotate to the required angle. The screw 225 is then tightened, and its extended end abuts against the side wall of the first annular boss 212 to fix the position of the rotating component 22. The above operations are performed in the direction requiring adjustment; if no adjustment is needed, no operation is required. After position calibration, the movement data is recorded, and the projected position of the transmitting antenna is marked. If the transmitting antenna needs calibration in the left-right direction, the device can be moved 90 degrees to position the transmitting antenna at the projected position, and then the aforementioned operations are performed. After marking the horizontal and vertical positions of the transmitting antenna, the precise position of the transmitting antenna is obtained. The final projected position of the transmitting antenna is used as the reference point for equipment installation. At the same time, the flatness and height of the installation position are corrected by referring to the adjustment values.

[0063] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
