[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1 As shown, the support frame body 1 is in the use state when it is on the soil ground. At this time, the auxiliary force-bearing plate 3 is installed on the supporting cylindrical rod 2 through a nut. The bottom end surface of the auxiliary force-bearing plate 3 contacts the soil ground, thereby increasing the force-bearing area of the support frame body 1 to prevent it from sinking into the soil ground. At the same time, the conversion adjustment cylinder 4 is threadedly engaged with the supporting cylindrical rod 2 and descends, so that the conversion adjustment cylinder 4 drives the lifting insertion rod 5 to descend and extend through the fixed anti-slip column 6 and insert into the soil ground, thereby preventing the support frame body 1 from generating horizontal displacement.

Figure 4 As shown, the support frame body 1 can be changed and adjusted according to the ground structure, so that the support frame body 1 can be applied to both cement ground and soil ground. When the lifting support rod 9 is raised and lowered, the lifting adjustment cylinder 8 is rotated by a tool to engage with the lifting support rod 9 threadedly, so that the lifting support rod 9 can be raised and lowered through the threaded engagement.

[0032] Example 2:

[0033] The difference from Example 1 is that the regular hexagonal groove of the fixed anti-detachment column 6 can also be set as a regular heptagonal groove, so that the fixed anti-detachment column 6 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the fixed anti-detachment column 6.

[0034] Example 3:

[0035] The difference from Example 1 is that the regular hexagonal prism of the fixed anti-rotation column 7 can also be set as a regular heptagonal prism, so that the fixed anti-rotation column 7 can only be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and disassembling the fixed anti-rotation column 7.
