After the clamping rod moves, it can squeeze the sleeve airbag, so that the airflow inside the sleeve airbag enters the inside of the conduit through the ventilation hard pipe and the ventilation hose. The thrust of the airflow can make the guide rod extend outward, thereby pushing the extension cover and the slide plate to the outside of the bearing seat, thereby increasing the contact area between the whole and the ground, and improving the overall stability; 3. A spike column is provided. The second clamping cap on the movable shaft is loosened and separated from the slide plate. Then the first clamping cap is tightened to clamp and limit the slide plate. After that, the guide rod is extended outward to push the extension cover to rotate around the movable shaft. After the extension cover rotates, the internal spike column can be inserted into the soil, thereby improving the stability of the surveying instrument body when surveying on the land.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Example 1: Please refer to Figure 1-Figure 9In order to ensure the stability of the existing surveying and mapping instruments during use, a rod is set at the bottom and inserted into the soil.

In actual landform surveying, it may be necessary to conduct surveying on cement or asphalt roads. When surveying on such roads, the rod cannot be inserted into the ground, thereby ensuring the stability of the surveying and mapping device, resulting in reduced adaptability of the surveying and mapping instrument itself. In order to solve this technical problem, the present embodiment discloses the following technical content, including a surveying and mapping instrument body 1, a support 2 is installed at the lower end of the surveying and mapping instrument body 1, and a plurality of support rods 3 are installed at the lower end of the support 2; and further comprising: a center rod 4 is fixedly installed at the bottom of the support rod 3, and the center rod 4 has a plurality of support rods 3 installed at the lower end of the support rod 2.

The wind wheel 71 is fixedly mounted on the guide rod 72, and the guide rod 72 is rotatably mounted on the support rod 3. The guide rod 72 is provided with a receiving groove 73, and a clamping rod 74 is installed on the side of the guide rod 72. One end of the clamping rod 74 located inside the guide rod 72 is connected to the guide rod 72 through the sleeve airbag 75. The airflow inside the sleeve airbag 75 is connected to the airflow inside the accommodating groove 73 through the circumferential air outlet holes 76.

[0029] When it is necessary to survey and map the topography, the stabilizing support component 5 is rotated at the bottom of the support rod 3 so that the stabilizing support component 5 is rotated on the center rod 4. When the stabilizing support component 5 is rotated to be parallel to the ground, the third clamping cap 6 on the center rod 4 is screwed so that the third clamping cap 6 clamps the stabilizing support component 5. At this time, the stabilizing support component 5 is placed on the ground to support the entire device. When surveying and mapping the topography on a cement or asphalt road surface, the second clamping cap 59 on the movable shaft 58 is screwed so that the second clamping cap 59 is clamped against the slide plate 53, thereby fixing the extension cover 57 on the slide plate 53. Then, the first clamping cap 56 on the connecting screw 55 is screwed to separate the first clamping cap 56 from the slide plate 53. At this time, when the wind blows from the outside, the wind force drives the wind wheel 71 and the guide rod 72 to rotate. After the guide rod 72 rotates, the clamping rod 74 is thrown outward under the action of centrifugal force. After the clamping rod 74 moves to the outside of the guide rod 72, it can squeeze the sleeve airbag 75, so that the airflow inside the sleeve airbag 75 enters the interior of the accommodating groove 73 through the air outlet 76, and the airflow inside the accommodating groove 73 enters the interior of the conduit 511 through the ventilation hard pipe 77 and the ventilation hose 78. When the airflow at the top increases, the driving rod 512 can be pushed to move toward the outside of the bearing seat 51. After the driving rod 512 moves, the extension cover 57 and the slide plate 53 can be pushed to move away from the bearing seat 51. By adjusting the movement of the bearing seat 51, the contact area between the whole and the cement or asphalt road surface can be increased, and the overall stability can be improved. When the surveying instrument body 1 needs to survey the topography on the land, the second clamping cap 59 on the movable shaft 58 is screwed to disengage the second clamping cap 59 from the slide plate 53, and the fixation between the extension cover 57 and the slide plate 53 is released. Then, the second clamping cap 59 on the connecting screw 55 is screwed. A clamping cap 56 is used to clamp the slide plate 53. After that, under the action of wind, the clamping rod 74 squeezes the sleeve airbag 75 under the centrifugal effect. The airflow inside the sleeve airbag 75 enters the interior of the conduit 511 through the ventilation hard tube 77 and the ventilation hose 78, thereby pushing the driving rod 512 to move. At this time, after the driving rod 512 moves, it can push the extension cover 57 to rotate around the movable shaft 58. As the extension cover 57 rotates, the spike column 510 on the inside can be inserted into the soil, thereby improving the stability of the surveying instrument body 1 when surveying on the land.

[0030] Embodiment 2: The technical contents disclosed in this embodiment are further improved on the basis of the above-mentioned embodiment 1. This embodiment discloses the following technical contents: a plurality of spiked columns 510 are evenly distributed inside the extension cover 57, and the plurality of spiked columns 510 are located between the extension cover 57 and the supporting seat 51 in the initial state.

[0031] In the initial state, the spike column 510 is located between the extension cover 57 and the bearing seat 51, so as to prevent the spike end of the spike column 510 from being directly exposed to the outside, and the spike end of the spike column 510 may cause harm to the staff when they carry the surveying instrument body 1 later.

[0032] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
