[0031] As Figures 1 to 4 shown:

[0032] Combined with the above content: The positioning component 7 includes a guide rail 71, a bidirectional lead screw 72, two moving seats 73, two lead screw nuts 74, and a first reciprocating motor 75. The guide rail 71 is fixedly arranged in the middle of the top of the workbench 4. The inside of the guide rail 71 is rotatably connected with the bidirectional lead screw 72 through a bearing. Both sides of the inner wall of the guide rail 71 are slidably connected with the moving seats 73.

[0039] In this embodiment: The anemometer and wind vane are affected by the airflow to cause the wind cups to rotate. During the rotation process, the wind cups sequentially contact a plurality of touch switches 16, thereby causing a plurality of lighting lamps 15 to flash sequentially, so as to realize the detection of the balance of the anemometer and wind vane.

[0040] In an alternative embodiment: The plurality of buffer plates 14 and the two arc-shaped gaskets 10 are both made of elastic rubber material.

Then, turn on the first motor switch on the surface of the switch panel 17. After the first reciprocating motor 75 starts, it drives the bidirectional lead screw 72 to rotate, and then through the two lead screw nuts 74, the two moving seats 73 slide relatively along the inner wall of the guide rail 71. When the two arc-shaped gaskets 10 respectively contact the bracket of the anemometer and wind vane, the anemometer and wind vane are fixed on the surface of the workbench 4. Then, extend the push rods of the three electric push rods 13 so that the three touch switches 16 are in the same horizontal plane as the rotating frame of the anemometer and wind vane. Then, start a plurality of second reciprocating motors 84 to rotate a plurality of gears 85, and then make a plurality of toothed plates 83 slide along the inner walls of a plurality of slide rails 82 respectively. When a plurality of touch switches 16 all move to the side of the wind cups, the anemometer and wind vane are affected by the airflow to cause the wind cups to rotate. During the rotation process, the wind cups sequentially contact a plurality of touch switches 16, thereby causing a plurality of lighting lamps 15 to flash sequentially. When some of the lighting lamps 15 cannot flash, there is a problem with the balance of the detected anemometer and wind vane. Finally, correct the anemometer and wind vane with the tools in the two sliding drawers 6.
