Compared with the prior art, the utility model has the following advantages:

1. The utility model has the advantages of simple structure, good use effect, convenient movement of the bracket, reduced work intensity of surveying and mapping workers, improved work efficiency, time-saving and labor-saving, and can be popularized and applied.

2. The bottom end of the supporting leg of the utility model is installed with a universal wheel assembly through the rotation of the hinge, and the supporting leg above the hinge is equipped with a fixed bolt to fix the universal wheel assembly on the supporting leg so that it is in a retracted state. Put away the fixing hole, which meets the requirement that the bracket can stand stably on the ground in the state of surveying and mapping, and prevents the bracket from deviating and affecting the measurement accuracy; the support leg located under the hinge is provided with a universal wheel assembly that is fixed by a fixing bolt. The mobile fixing hole fixed on the supporting leg to make it in use ensures that the universal wheel assembly is fixedly connected with the supporting leg during the sliding process of the universal wheel, and the bracket will not shake.

3. The utility model can adjust the depth of the telescopic rod inserted into the support sleeve through the fixed pin, adjust the length of the support leg, and indirectly adjust the height of the surveying instrument placed on the support platform to ensure that the support can be within a certain height range use, and improve the measurement accuracy.

4. The utility model has a good use effect and does not require the surveyors to lift the bracket to adjust the surveying position back and forth, which saves the physical strength of the surveyors, enables the surveyors to concentrate more, ensures the accuracy of the surveying data, and better meets the needs of the surveyors .

The technical solutions of the present utility model will be further described in detail through the drawings and embodiments below.
