The supporting and fixing main rods 6 include a supporting and fixing part 1 and a ground supporting part 2, with the ground supporting part 2 integrally set below the supporting and fixing part 1.

[0036] In this embodiment, the support and fixing part 1 has a cylindrical structure with a smooth inner wall. The support and fixing part 1 is used to fix the measuring tripod 7 and adjust the height of the measuring tripod 7, such as... Figure 2 As shown, since the bottoms of the three legs of the measuring tripod 7 are all pointed, and a pedal 71 is provided above the pointed top, the bottoms of the three legs of the measuring tripod 7 are inserted into the support fixing part 1 and locked onto the inner wall, and the pedal 71 is locked onto the upper end face of the support fixing part 1, thereby fixing the measuring tripod 7 above the support fixing part 1, thereby increasing the height of the measuring tripod 7.

[0037] The ground support 2 is an inverted cone with the tip of the inverted cone facing the ground. The bottom surface of the inverted cone is integrally formed on the lower end surface of the support and fixing part 1, and the diameter of the bottom surface is the same as the diameter of the lower end surface of the support and fixing part 1. The ground support 2 is used to stably support the support and fixing part 1. The tip of the ground support 2 is inserted into the ground for fixation, thereby stabilizing the measuring tripod 7.

[0038] Each supporting main rod 6 is provided with two fixing connectors 3, and the fixing connectors 3 are welded and fixed to the middle of the supporting main rod 6. The two fixing connectors 3 on the supporting main rod 6 are respectively set perpendicular to the supporting main rod 6, and the included angle between the two fixing connectors 3 is 60°. All fixing connectors 3 are at the same height of the supporting main rod 6, which facilitates the stability of the device.

[0039] Preferably, the fixing connector 3 is in the shape of a cuboid, and bolt holes are provided on the fixing connector 3.

[0040] In this embodiment, the telescopic connecting rod 4 is cuboid, and a plurality of bolt holes are arranged on the telescopic connecting rod 4, the telescopic connecting rod 4 is arranged between adjacent support fixed main rods 6, and the two ends of the telescopic connecting rod 4 are fixedly connected with the fixed connecting pieces 3 through the fixing pieces, so that the three support fixed main rods 6 are fixed, and the height and the adjacent distance of the support fixed main rods 6 are adjusted.

[0041] The telescopic connecting rod 4 is used for adjusting the height of the support fixed main rod 6, specifically, the telescopic connecting rod 4 is arranged obliquely, and then is rotated by a certain angle clockwise or counterclockwise, the two sides of the telescopic connecting rod 4 are fixedly connected with the fixed connecting pieces 3, so that the two fixed connecting pieces 3 can be at different heights, and at the same time, the two support fixed main rods 6 also have a relative height difference, that is, the height of the support fixed main rod 6 is adjusted.

[0042] The telescopic connecting rod 4 is used for adjusting the adjacent distance of the support fixed main rod 6, specifically, the bolt holes arranged along the length direction of the telescopic connecting rod 4 are arranged on the telescopic connecting rod 4, the bolt holes at different positions are fixedly connected with the fixed connecting pieces 3 on the two sides, so that the transverse distance between the two fixed connecting pieces 3 can be changed, and at the same time, the transverse distance between the two support fixed main rods 6 can also be changed, that is, the shape of the triangle formed by the support fixed main rods 6 is changed.

[0043] As shown in Figure 3 When the measuring instrument and the measuring foot stand 7 are located in a low-lying area, the height is limited, and the measuring instrument cannot measure the left scale 8, at this time, the utility model is supported at the bottom of the measuring foot stand 7, and the measuring instrument is lifted, as shown in Figure 4 At this time, the measuring instrument can observe the left scale 8 because it is lifted. Specifically, the height and the adjacent distance of the support fixed main rod 6 are adjusted through the telescopic connecting rod 4 and the fixed connecting piece 3 to adapt to the position and the height of the erected measuring foot stand 7, then the support fixed main rod 6 is fixed to the ground through the ground supporting part 2, then the bottom of the measuring foot stand 7 is inserted into the inside of the support fixed main rod 6 and is clamped on the inner wall, and at the same time, the pedal 71 is clamped on the upper end surface of the support fixed part 1, the measuring foot stand 7 is clamped tightly through hand pressing or foot stepping the pedal 71, so that the measuring foot stand 7 is fixed, and the height of the measuring foot stand 7 is adjusted to measure, if the height of the adjusted support fixed main rod 6 is not the same, the length of each foot stand of the measuring foot stand 7 is adjusted, so that the measuring instrument on the measuring foot stand 7 is arranged horizontally.

[0044] In this embodiment, the fixing piece is a butterfly bolt 5, the butterfly bolt 5 is provided with a fixed nut, the butterfly bolt 5 passes through the bolt holes on the telescopic connecting rod 4 and the bolt holes on the fixed connecting piece 3 in sequence, and then the support fixed main rod 6 is fixed, so that the support fixed main rod 6 forms a high-strength triangular component.

[0045] Based on the close connection of the telescopic connecting rod 4 and the fixed connecting piece 3, the height and the adjacent distance of the supporting and fixing main rod 6 are adjusted through the corresponding bolt holes, the situation of the field terrain is well adapted, the influence of factors such as limited field of view and obstacles is avoided, the field of view of target measurement is expanded while the height measuring support 7 is increased, target recognition is more accurate, the authenticity and accuracy of measurement data are improved, and the measurement efficiency is greatly improved.

[0047] The installation process when the embodiment is measured is as follows:

[0048] According to the field terrain, the height and the adjacent distance of the supporting and fixing main rod 6 are adjusted through the telescopic connecting rod 4 to adapt to the requirements of the field measurement field of view and height;

[0049] After adjusting the height and the adjacent distance, the ground supporting part 2 of the supporting and fixing main rod 6 is fixed to the ground, preventing it from being suspended or not effectively fixed, so that it closely fits the ground; the bottom of the measuring support 7 is respectively clamped into the inner wall of the supporting and fixing part 1 of the supporting and fixing main rod 6, the measuring support 7 is clamped tightly by hand pressure or foot pedal 71, the measuring support 7 is adjusted to be horizontal to the measuring instrument, and after centering and leveling, the measurement operation can be started;

[0050] During the measurement process, the device cannot be disassembled or the height and the adjacent distance cannot be adjusted; after the measurement is completed, only the butterfly bolt 5 is loosened, the adjacent supporting and fixing main rod 6 is adjusted to the same height, and the device is moved to the next measurement point for continuous use;

[0051] After use, the butterfly bolt 5 is completely loosened, and the supporting and fixing main rod 6 and the telescopic connecting rod 4 are bundled with a rain cloth to prevent loss.
