[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0025] Embodiment 1: A surveying and mapping auxiliary device, as Figures 1 - 4 shown, includes a surveying and mapping instrument 1. The surveying and mapping instrument 1 is connected with a load-bearing block 3 through a connecting bolt 2. The lower end of the load-bearing block 3 is rotatably connected with at least three support rods 4 through an extension rod 5. The extension rod 5 is slidably arranged inside the support rod 4, and the extension rod 5 can extend upward to the outside. A buffer 9 is fixedly arranged in the lower half of the inside of the support rod 4. The buffer 9 is located below the extension rod 5, and the buffer 9 is used for sinking buffering. The staff connects the surveying and mapping instrument 1 with the load-bearing block 3. When rotating the support rod 4, the extension rod 5 is driven to rotate together, and then the support rod 4 is connected with the placement surface. When the surveying and mapping instrument 1 slides downward driven by the support legs, it will drive the load-bearing block 3 to slide downward together. At the same time, by setting the extension rod 5 to be connected with the support rod 4 through the set connection structure, the extension rod 5 can provide a certain amount of support. If the connection structure slips, the extension rod 5 slides inside the support rod 4, and then the extension rod 5 will slide downward and touch the buffer 9, so that the buffer 9 can buffer part of the impact force of the extension rod 5, and then the surveying and mapping instrument 1 can be supported when sliding downward, avoiding damage to the surveying and mapping instrument 1.

[0026] As Figures 1 - 4As shown, a fixed bottom plate 7 is fixedly arranged on the inner wall of the support rod 4. A connecting block 8 is fixedly installed on the upper surface of the fixed bottom plate 7. A buffer 9 is fixedly arranged at the upper end of the connecting block 8. A sliding groove 11 is formed inside the support rod 4, and the sliding groove 11 is slidably connected with the extension rod 5. By arranging the fixed bottom plate 7 and the connecting block 8, the buffer 9 can be connected to the support rod 4 through the connecting block 8. Thus, when the extension rod 5 slides downward and contacts the buffer 9, the buffer 9 can buffer a part of the impact force. By arranging the sliding groove 11 and making the sliding groove 11 slidably connected with the extension rod 5, the extension rod 5 can slide more smoothly.

[0027] As Figures 1 - 2 shown, a fastening bolt 10 is screwed onto the extension rod 5. The extension rod 5 is limited and fixed to the support rod 4 through the fastening bolt 10. A number of adjustment grooves 6 are formed on the extension rod 5, and the fastening bolt 10 is screwed into the adjustment grooves 6. The adjustment grooves 6 are used for the gear adjustment of the extension rod 5. At the same time, the extension rod 5 is screwed onto the support rod 4 through the fastening bolt 10, which can fix the position of the extension rod 5 and prevent the extension rod 5 from sliding inside the support rod 4 after installation. At the same time, the adjustment grooves 6 formed on the extension rod 5 enable the staff to adjust the height of the extension rod 5 during installation, so as to be more suitable for the current environment.

[0028] As Figures 1 - 4 shown, a first threaded hole 12 is formed at the lower end of the surveying instrument 1, and a second threaded hole 13 is formed on the load-bearing block 3. A connecting bolt 2 is screwed into the first threaded hole 12, and the connecting bolt 2 is screwed into the second threaded hole 13 away from the first threaded hole 12. The connecting bolt 2 is used for connecting the surveying instrument 1 and the load-bearing block 3. By arranging the connection between the surveying instrument 1 and the load-bearing block 3 through the connecting bolt 2, it is convenient for the staff to install and separate the surveying instrument 1, the load-bearing block 3 and the support rod 4, so as to protect the surveying instrument 1 during transportation and avoid damage to the surveying instrument 1 due to its overall length during transportation.

[0029] Working principle: The staff connects the surveying instrument 1 and the load-bearing block 3. When rotating the support rod 4, the extension rod 5 is driven to rotate together, and then the support rod 4 is connected to the placement surface. When the surveying instrument 1 slides downward driven by the support legs, the load-bearing block 3 will be driven to slide downward together. At the same time, by arranging the connection between the extension rod 5 and the support rod 4 through the fastening bolt 10, the extension rod 5 can provide a certain support. If the fastening bolt 10 slips, the extension rod 5 will slide inside the support rod 4, and then the extension rod 5 will slide downward and touch the buffer 9, so that the buffer 9 can buffer a part of the impact force of the extension rod 5, and thus the surveying instrument 1 can be supported when sliding downward to avoid damage to the surveying instrument 1.

[0030] 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 substitutions or changes, shall be covered by the protection scope of the present utility model.
