[0027] The adjustment assembly includes a mounting ring 12, which is slidably connected to the outside of the first support rod 3. Two fixing blocks 13 are fixedly connected to the outside of the mounting ring 12. The two fixing blocks 13 are internally threaded with second bolts 14. A housing 15 is fixedly connected to the outside of the mounting ring 12.

[0028] A groove 16 is provided between the housing 15 and the interior of the first support rod 3. A limiting block 17 is slidably connected inside the groove 16. A pull rod 18 is fixedly connected to one side of the limiting block 17. The outer side of the pull rod 18 is slidably connected to the interior of the housing 15. A spring 19 is provided on the outer side of the pull rod 18. Grooves 20 are provided at equal intervals on the outer side of the second support rod 10. One side of the limiting block 17 abuts against one side of the inner wall of the groove 20.

[0029] The adjustment assembly includes a second sleeve 22, which is slidably connected to the outside of the column 2. A second mounting block 23 is fixedly connected to the outside of the second sleeve 22 at equal intervals. A collar 24 is fixedly connected to the outside of the first support rod 3. A third mounting block 25 is fixedly connected to the outside of the collar 24. A connecting rod 26 is provided between one side of the second mounting block 23 and the third mounting block 25. A second screw 28 is provided inside the connecting rod 26.

[0030] The outer side of the second sleeve 22 is fixedly connected to the second threaded block 27, and the inner thread of the second threaded block 27 is connected to the third screw 29. The outer side of the column 2 is provided with positioning holes at equal intervals, and the outer side of the third screw 29 is connected to the inner thread of the positioning hole.

[0031] In the above technical solution, considering that existing tripods are large in size and generally need to be disassembled into multiple parts for easy transportation, requiring considerable time to assemble the various parts during use and being inconvenient to operate, the specific operation is as follows: By setting a limiting component and an adjusting component, when assembling the tripod, firstly, the first sleeve 4 is placed on the column 2 and moved upward to the designated position, and the second sleeve 22 will also be placed on the column 2. Then, the first screw 9 in the first threaded block 8 is screwed into the column 2, thereby fixing the first sleeve 4 to the column 2. Then, the pull rod 18 is pulled outward, the spring 19 is compressed, the limiting block 17 enters the receiving groove 16, and then the second support rod is... Pull the first support rod 10 outward from the bottom of the first support rod 3 to a suitable length, then release the pull rod 18. Under the rebound of the spring 19, it will fit against the outer wall of the second support rod 10. Slightly adjust the second support rod 10 up and down to allow the limiting block 17 to re-enter the groove 20 and fix the second support rod 10. Then adjust the other two sets of support rods in the same way to erect the tripod. Then slide the second sleeve 22 upward and use the connecting rod 26 to open the first support rod 3 to a suitable position. Then screw the third screw 29 in the second threaded block 27 into one of the positioning holes to fix the second sleeve 22. Finally, place the installed tripod horizontally on the ground and place the surveying instrument on the mounting plate 1 for use. By setting the limiting component and the adjustment component, the installation process of the tripod is simplified, and the assembly and disassembly are quick, reducing waiting and adjustment time. Because the adjustment structure is simple, it is easy for users to operate, requires no complicated tools, and the size is reduced after disassembly, making it convenient for transportation and storage.

[0032] Reference Figures 1 to 7In a preferred embodiment, a keyway 21 is provided on the outer side of the second support rod 10, and a flat key is provided inside the first support rod 3; a pedal 11 is fixedly connected to the outer side of the second support rod 10; by providing the flat keyway 21, the sliding trajectory of the second support rod 10 can be controlled to ensure that the limiting block 17 and the groove 20 always remain in the corresponding state; the pedal 11 can provide a foothold for the user to apply force, thereby fixing the support rod to the soil and increasing the stability of the tripod.

[0033] Working principle: When assembling the tripod, first, place the first sleeve 4 onto the column 2 and move it upwards to the designated position. The second sleeve 22 will also be placed onto the column 2. Then, screw the first screw 9 in the first threaded block 8 into the column 2, thus fixing the first sleeve 4 to the column 2. Next, pull the pull rod 18 outwards, compressing the spring 19 and causing the limiting block 17 to enter the receiving groove 16. Then, pull the second support rod 10 outwards from the bottom of the first support rod 3 to the appropriate length. Then, release the pull rod 18. Under the rebound of the spring 19, it will fit against the outer wall of the second support rod 10. Slightly adjust the second support rod 10 up and down to allow the limiting block 17 to re-enter the groove 20 and fix the second support rod 10. Then, adjust the other two sets of support rods in the same way to erect the tripod. Finally, slide the second sleeve 22 upwards. After using the connecting rod 26 to open the first support rod 3 to a suitable position, screw the third screw 29 in the second threaded block 27 into one of the positioning holes to fix the second sleeve 22. Finally, place the assembled tripod horizontally on the ground and place the surveying instrument on the mounting plate 1 for use. When disassembling, simply pull the pull rod 28 again to move the limit block 17 out of the groove 20, and the second support rod 10 can be retracted into the first support rod 3. Then loosen the third screw 29 and pull the second sleeve 22 down to the bottom positioning hole. The connecting rod 26 causes the first support rod 3 to rotate and move towards the column 2. Then tighten the third screw 29 to fix the second sleeve 22, completing the folding and storage of the tripod.
