[0025] Please see Figures 1-4 This utility model provides a land surveying mark positioning structure, including a positioning platform 1. The positioning platform 1 is connected and fixed to the top of the support of the surveying machine by bolts or other means. A positioning plate 2 is slidably connected to the upper surface of the positioning platform 1 in the left and right direction. A positioning groove 5 is opened on the upper surface of the positioning plate 2. A slider 7 is slidably connected between the inner walls of the positioning groove 5. A positioning plate 3 is fixed to the top of the slider 7. A placement groove 4 is opened on the upper surface of the positioning plate 3 for placing the land surveying machine. A threaded shaft 6 is rotatably connected to one side wall of the positioning groove 5. A threaded hole 9 is opened on one side wall of the slider 7. The other end of the threaded shaft 6 passes through the threaded hole 9 and is fixed to a rotating plate 8. The threaded shaft 6 and the slider 7 are connected by a threaded transmission. The operator can rotate the rotating plate 8 to move and adjust the positioning plate 3. Since the threaded transmission has a self-locking force, the slider 7 can move and stop at will.

[0026] An adjusting shaft 10 is rotatably connected to one side of the outer wall of the positioning platform 1. A rotating plate 11 is fixed to the other end of the adjusting shaft 10. An adjusting gear 22 is tightly fixed to the outer wall of the adjusting shaft 10. An adjusting strip 20 is fixed to the outer wall of the positioning plate 1. An adjusting rack 21 is provided along the length of the side wall of the adjusting strip 20 near the adjusting gear 22. The adjusting rack 21 and the adjusting gear 22 are meshed and connected for fine adjustment of the surveying machine in the left and right directions.

[0027] The outer wall of the positioning platform 1 is fixed with a fixing seat 14. A fixing channel that runs through the left and right sides is opened on one side wall of the fixing seat 14. An insert 12 is slidably connected to the inner wall of the fixing channel. The outer wall of the adjusting shaft 10 is provided with symmetrically distributed slots 13 along the circumferential direction. The slots 13 and the insert 12 are engaged to further limit and fix the position of the adjusting shaft 10.

[0028] The other end of the insert 12 is fixed with a pull strip 15 for further fixing the position of the insert 12. A limit seat 16 is fixed to one side of the outer wall of the fixing seat 14. A limit channel is opened on the upper surface of the limit seat 16 in the vertical direction. A limit strip 17 is slidably connected to the inner wall of the limit channel. A pull block 19 is fixed to the top of the limit strip 17. A limit hole 18 is opened on the upper surface of the insert 12 in the vertical direction, and the limit strip 17 passes through the limit hole 18, thereby fixing the position of the insert 12, thereby fixing the position of the adjusting shaft 10, and thus fixing the position of the positioning plate 12.

[0029] This solution includes the following working process: When positioning the surveying machine, it is placed inside the placement slot 4, and the positioning platform 1 is connected and fixed to the top of the land surveying machine. When adjusting the positioning position of the marker, the pull block 19 is moved, which moves the limiting strip 17, separating it from the limiting hole 18. Then, the pull rod 15 is pulled, which moves the insert strip 12, separating it from the slot 13. The rotating plate 11 is rotated, which drives the adjusting shaft 10 to rotate. The adjusting shaft 10 drives the adjusting gear 22 to rotate, and the meshing transmission between the adjusting gear 22 and the adjusting rack 21 drives the adjusting strip. The adjustment bar 20 moves, and the positioning plate 11 moves. By recording the number of rotations of the rotating plate 11, the left and right movement distance can be finely adjusted. Then, the insertion bar 12 is moved and engages with the slot 13. The limiting bar 17 is moved downward and passes through the limiting hole 18 to fix the position of the adjustment shaft 10, thereby fixing the position of the positioning plate 12. Then, the rotating plate 8 is rotated, which drives the threaded shaft 6 to rotate. The threaded shaft 6 drives the slider 7 to move through the threaded transmission. The slider 7 drives the positioning plate 23 to move. The positioning plate 23 drives the surveying machine to make fine adjustments in the front and back directions, and then performs positioning and surveying processing.
