[0022] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a positioning device for a surveying instrument used in surveying engineering, including a tripod main body 1. A vertical rod 2 is fixed to the bottom surface of the tripod main body 1. A plurality of first connecting rods 3 are rotatably connected to the lower part of the outer side of the vertical rod 2. One end of the first connecting rod 3 far from the vertical rod 2 is rotatably connected to a second connecting rod 4. One end of the second connecting rod 4 is rotatably connected to the outer side of the tripod main body 1. One end of the first connecting rod 3 far from the vertical rod 2 is also rotatably connected to a third connecting rod 5. The lower end of the third connecting rod 5 is rotatably connected to a connecting rod 6. A support 7 is slidably connected to the outer side of the connecting rod 6. The lower end of the connecting rod 6 is rotatably connected to a fourth connecting rod 8. The lower end of the fourth connecting rod 8 is rotatably connected to a fifth connecting rod 9. One end of the fifth connecting rod 9 is fixed with a connecting plate 10. Rotating seats 11 are rotatably connected to both sides of the connecting plate 10. One end of the connecting plate 10 is fixed with a first support plate 12;

[0023] When the tripod legs are unfolded, the tripod legs open, causing the first connecting rod 3 and the second connecting rod 4 to also open at an angle. The lower end position of the first connecting rod 3 is raised and the connecting rod 6 is pulled upward through the third connecting rod 5. The connecting rod 6 pulls the fifth connecting rod 9 on the connecting plate 10 through the fourth connecting rod 8, causing the connecting plate 10 to rotate downward along the rotating seat 11. The connecting plate 10 drives the first support plate 12 to rotate downward, making the first support plate 12 turn into a horizontal state, thus forming a horizontal contact with the ground. By increasing the contact area, the stability of the tripod main body 1 is improved. After using the tripod main body 1, when the tripod legs are folded, the tripod legs close, causing the first connecting rod 3 and the second connecting rod 4 to also close at an angle. The lower end position of the first connecting rod 3 is lowered and the connecting rod 6 is pulled downward through the third connecting rod 5. The connecting rod 6 pushes the fifth connecting rod 9 on the connecting plate 10 through the fourth connecting rod 8, causing the connecting plate 10 to rotate upward along the rotating seat 11. The connecting plate 10 drives the first support plate 12 to rotate upward, making the first support plate 12 fit with the tripod legs, thus reducing the occupied space and facilitating carrying and transportation. Through the above process, when the tripod main body 1 is unfolded, the first support plate 12 automatically turns into a horizontal state. By forming a horizontal contact with the ground and increasing the contact area, the stability of the tripod main body 1 is improved. When the tripod main body 1 is stored, the first support plate 12 automatically turns into a folded state, facilitating storage and transportation.

[0024] Further, both sides of the first support plate 12 are rotatably connected with second support plates 13. Slots 14 are formed on the opposite sides of the two second support plates 13. An installation groove 15 is formed inside the first support plate 12. A gear 16 is rotatably connected to the middle of the inner side of the installation groove 15. Both sides of the gear 16 are meshed with racks 17. One end of each rack 17 passes through the inner side of the installation groove 15 and the inside of the first support plate 12 and is inserted into the inner side of the slot 14 in a plug-in fit. A transmission rod 18 is rotatably connected to the top surface of the first support plate 12. The lower end of the transmission rod 18 passes through the top surface of the first support plate 12 and extends into the interior of the installation groove 15 and is coaxially and fixedly connected to one end of the rotating shaft of the gear 16. A knob 19 is fixed to the upper end of the transmission rod 18. Anti-slip patterns are formed on the outer side of the knob 19. One end of the support 7 is fixedly connected to the outer side of the tripod body 1. One end of the rotating seat 11 is fixedly connected to the outer side of the tripod body 1;

[0025] By unfolding the two second support plates 13 and then rotating the knob 19, the knob 19 drives the gear 16 to rotate through the transmission rod 18. The gear 16 drives the two racks 17 to move towards both sides and are respectively inserted into the slots 14 on the two second support plates 13, thereby fixing the two second support plates 13. Through the above process, the supporting area in contact with the ground can be expanded, so as to adapt to softer soil and improve the application range of the device.

[0026] The specific usage mode and function of this embodiment: When the present utility model unfolds the tripod legs, the tripod legs open, causing the first connecting rod 3 and the second connecting rod 4 to also open at an angle. The lower end position of the first connecting rod 3 is raised and the connecting rod 6 is pulled upward through the third connecting rod 5. The connecting rod 6 pulls the fifth connecting rod 9 on the connecting plate 10 through the fourth connecting rod 8, causing the connecting plate 10 to rotate downward along the rotating seat 11. The connecting plate 10 drives the first support plate 12 to rotate downward, so that the first support plate 12 is turned into a horizontal state, thereby forming a horizontal contact with the ground. By increasing the contact area, the stability of the tripod body 1 is improved. After using the tripod body 1, fold the tripod legs. The tripod legs close, causing the first connecting rod 3 and the second connecting rod 4 to also close at an angle. The lower end position of the first connecting rod 3 is lowered and the connecting rod 6 is pulled downward through the third connecting rod 5. The connecting rod 6 pushes the fifth connecting rod 9 on the connecting plate 10 through the fourth connecting rod 8, causing the connecting plate 10 to rotate upward along the rotating seat 11. The connecting plate 10 drives the first support plate 12 to rotate upward, so that the first support plate 12 fits with the tripod legs, thereby reducing the occupied space and facilitating carrying and transportation;

[0027] By unfolding the two second support plates 13 and then rotating the knob 19, the knob 19 drives the gear 16 to rotate through the transmission rod 18. The gear 16 drives the two racks 17 to move towards both sides and are respectively inserted into the slots 14 on the two second support plates 13, thereby fixing the two second support plates 13.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
