[0002] Geographic survey is the work of mapping topographic maps of geographical structures, that is, measuring the projection position and elevation of objects and terrain on the earth's surface on the horizontal plane, reducing them at a certain ratio, and drawing them into topographic maps with symbols and annotations. During the survey, survey equipment can be set up in the field to survey the terrain of the current area. However, during the use of the survey equipment in the prior art, the sliding connection between the support leg and the telescopic leg is limited by the friction between the bolt and the telescopic leg. During use, it needs to be tightened, but the threaded matching method is easy to loosen after the telescopic leg is vibrated, resulting in unstable equipment support and affecting the equipment survey. Therefore, it is necessary to improve the prior art. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model adds structures such as a positioning rod, a spring and a guide sleeve on the support frame. During use, the positioning rod can be driven by the elastic force of the spring to be inserted into the interior of the telescopic frame, and then penetrate the telescopic frame and be inserted into the other side of the guide sleeve. When the equipment is vibrated, the positioning rod will not slide out of the interior of the telescopic frame, so that the equipment can be more stable after being supported.
