[0024] In one embodiment of the utility model: a threaded hole 47 is penetrated through the left end of the limit block 44, a straight hole 48 is penetrated through the right end of the limit block 44, a threaded rod 42 is arranged at the inner left end of the limit block 44, and the threaded rod 42 is threadedly connected to the threaded hole 47, and the straight rod 45 is arranged inside the straight hole 48 of the limit block 44.

[0025] In one embodiment of the present invention: the tops of the threaded rod 42 and the straight rod 45 are both fixedly connected to a limited top cover 46 .

[0026] In one embodiment of the present invention, the slider 49 is slidably connected to the interior of the limiting groove 43 .

[0027] In one embodiment of the utility model: the auxiliary mechanism 5 includes a fixed plate 51 and a fixed seat 52 fixedly mounted on the surface of the base 1, the fixed seat 52 is internally hinged with a hinge frame 53, the upper end of the fixed plate 51 close to the fixed seat 52 is fixedly connected with a telescopic spring 54, the other end of the telescopic spring 54 is fixedly connected to the hinge frame 53, the end of the hinge frame 53 away from the telescopic spring 54 is fixedly connected with a connecting shaft 55, and the end of the connecting shaft 55 away from the hinge frame 53 is fixedly connected with a clip 56.

[0028] In one embodiment of the present invention: four auxiliary mechanisms 5 are provided and distributed in a circular array.

[0029] In one embodiment of the present invention, the clip 56 is in contact with the rotating column 3 .

[0030] Example 1, please refer to the attached Figure 1 -Attached Figure 3 The left end of the limit block 44 is penetrated with a threaded hole 47, the right end of the limit block 44 is penetrated with a straight hole 48, the threaded rod 42 is arranged at the inner left end of the limit block 44, and the threaded rod 42 is threadedly connected with the threaded hole 47, and the straight rod 45 is arranged inside the straight hole 48 of the limit block 44. The threaded rod 42 and the threaded hole 47 are threadedly connected. Through the rotation of the rotating motor 41, the threaded rod 42 can drive the limit block 44 to move up and down. The wind direction rod 7 is arranged inside the limit block 44, and the direction can be quickly determined according to the rotation of the wind direction rod 7, which is convenient for rescue;

[0031] The tops of the threaded rod 42 and the straight rod 45 are fixedly connected to a limit top cover 46, which plays a role of limiting and fixing to prevent the limit block 44 from moving the wind direction rod 7 to a too high position.

[0032] Example 2, please refer to the attached Figure 1 -Attached Figure 4 A telescopic spring 54 is fixedly connected to the upper end of the fixed plate 51 near the fixed seat 52, and the other end of the telescopic spring 54 is fixedly connected to the hinge frame 53. According to the elasticity of the telescopic spring 54, the stability can be improved;

[0033] The clip 56 is in contact with the rotating column 3 , and the inner side surface of the clip 56 is smooth, which will not affect the rotation of the rotating column 3 .

[0034] Specifically, when wind direction identification is not performed, the rotating motor 41 drives the threaded rod 42 to rotate, and the limit block 44 moves downward along the threaded rod 42. The slider 49 and the straight rod 45 ensure the stability of the movement of the limit block 44. When the limit block 44 moves to the bottom, the wind direction rod 7 can be removed to protect it.

[0035] Specifically, the four clips 56 assist in clamping the rotating column 3. When the rotating column 3 tilts to one side due to strong wind, the reaction force of the telescopic spring 54 sends a thrust back, thereby preventing the bearing seat 2 from being damaged due to excessive pressure and ensuring the stability of the entire device during operation.

[0036] Working principle:

[0037] The direction is determined by the rotation of the wind direction rod 7, so as to quickly determine the position and implement rescue. When the wind direction is not identified, the rotating motor 41 drives the threaded rod 42 to rotate, and the limit block 44 moves downward along the threaded rod 42. The slider 49 and the straight rod 45 ensure the stability of the movement of the limit block 44. When the limit block 44 moves to the bottom, the wind direction rod 7 can be removed to protect it. During the operation of the wind direction rod 7, the four clips 56 assist in clamping the rotating column 3. When encountering strong wind force and the rotating column 3 tilts to one side, the reaction force of the telescopic spring 54 sends out a thrust back, which avoids the bearing seat 2 from being damaged by too much pressure, thereby ensuring the stability of the entire device during operation. At this point, the entire work process ends.

[0038] The above-mentioned front, back, left, right, top and bottom are all based on the figures in the specification. Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
