The expansion angle of the upper adjustment arm is adjusted using the central connecting block, and then it is placed flat on the installation position using the adaptive support legs. If there are obstructions between the upper adjustment arm and the central connecting block, the operator can adjust the misaligned mounting block on one side using the connecting shaft until the lever is in the appropriate position, then rotate the fastening bolt to complete the fixation. If the terrain at the installation location is complex and has elevation differences, the operator can use the three sets of adaptive support legs in different positions to contact the ground at different heights, and increase the extension range by stretching the misaligned mounting block on one side. Once the position is determined, the operator steps on the pressing plate to insert the positioning pin into the ground.

[0017] Through the above-described setup and process, the structure, during use, can improve the lateral flexibility of the support structure through the cooperation of staggered mounting blocks, connecting shafts, fastening bolts, and levers, and increase the stability of the support structure's ends through positioning pins and pressing plates. This enhances the overall flexibility and stability of the structure. Attached Figure Description

[0026] The adaptive support foot 5 also includes a pressing plate 501 and a positioning pin 502. The pressing plate 501 is sleeved on the upper end of the adaptive support foot 5, and the positioning pin 502 is fixedly installed on the bottom of the pressing plate 501.

[0027] In this embodiment, the adaptive support foot 5 has an overall fin-like structure with a flat bottom and a triangular vertical plate in the middle. The pressing plate 501 has a strip-shaped groove structure on the side facing the adaptive support foot 5. The upper adjustment arm 4 also includes a middle connecting block 401, a misaligned mounting block 402, a connecting shaft 403, a fastening bolt 404, and a lever block 405. The upper adjustment arm 4 has a strip-shaped structure installed obliquely upward on the side end, and the strip-shaped structure is installed on the side of the upper adjustment arm 4 facing the middle connecting frame 6.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when the adaptive support leg 5 with fin-like structure is connected, its upper triangular vertical plate can connect with the lever block 405 without affecting the bottom plane support. The upwardly mounted strip structure on the side of the upper adjusting arm 4 can establish a stable connection with the middle connecting block 401.

[0029] In this embodiment, the middle connecting block 401 is movably connected to the end of the strip structure on the side of the upper adjusting arm 4, the misaligned mounting block 402 is movably connected to the end of the upper adjusting arm 4 and is installed in a horizontal form; the connecting shaft 403 passes through the upper adjusting arm 4, two sets of fastening bolts 404 are provided, and they are respectively threadedly connected to the misaligned mounting block 402 from both sides; the lever block 405 is movably connected to the upper end of the adaptive support foot 5 through the shaft.

[0030] Specifically, such as Figure 2 and Figure 4 As shown, the through-through of the connecting shaft 403 enables the lever 405 to have rotational support, and the fastening bolt 404 can fix its rotational position from both sides.

[0031] In this embodiment, the misaligned mounting block 402 has an overall "I" shaped structure, with the central horizontal partition structure as the center, and its two sides are respectively connected to the upper adjustment arm 4 and the lever block 405; the upper adjustment arm 4 and the adaptive support foot 5 are respectively provided in three sets.

[0032] The working principle and usage process of this utility model are as follows: When using this structure, the operator installs it in a fixed position. The expansion angle of the upper adjusting arm 4 is adjusted by the middle connecting block 401, and then it is placed flat on the installation position by the adaptive support foot 5. If there is an obstruction between the upper adjusting arm 4 and the middle connecting frame 6, the operator can adjust the misaligned installation block 402 on one side by connecting shaft 403 until the lever 405 is in the appropriate position, and then rotate the fastening bolt 404 to complete the fixation. If the terrain of the installation position is relatively complex and there is a height difference, the operator can use three sets of adaptive support feet 5 in different positions to contact the ground at different heights, and increase the extension range by stretching the misaligned installation block 402 on one side. After the position is determined, step on the pressing plate 501 to insert the positioning pin 502 into the ground.
