[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-5The utility model embodiment is a telescopic metal power pole based on flange connection, which includes: a first column 1, the interior of the first column 1 is fixedly connected with a second fixing block 4 for connecting and fixing the first column 1 and a threaded rod 6, the top of the second fixing block 4 is fixedly connected with a threaded rod 6 for adjusting and fixing the structure, the outer ring of the threaded rod 6 is threadedly connected with a positioning hole 8 for positioning and fixing the structure, the positioning hole 8 is opened inside a third fixing block 7 for fixing and connecting the second column 5, the outer ring of the third fixing block 7 is fixedly connected with the second column 5 for supporting and connecting the structure, the outer ring of the second column 5 is penetrated by a first bolt 9 for fixing and connecting the structure, the outer ring of the first bolt 9 is threadedly connected with a fourth fixing block 10 for fixing and connecting the structure The outer ring of the fourth fixing block 10 is fixedly connected to the fifth fixing block 11 for fixing and connecting the structure. The top of the fifth fixing block 11 is penetrated by a second bolt 12 for fixing and connecting the structure. The outer ring of the second bolt 12 is threadedly connected with a nut 13 for adjusting and fixing the structure. The bottom end of the first column 1 is fixedly connected to a base 2 for supporting and connecting the structure. The top of the first column 1 is fixedly connected to a first fixing block 3 for connecting and fixing the structure. The number of the first bolt 9 and the second bolt 12 is several for fixing and connecting the structure. The sizes of the second column 5 and the fourth fixing block 10 are matched to ensure the stability and matching of the structure. The diameter of the first column 1 is greater than the diameter of the second column 5 to ensure the stability and strength of the structure.

[0026] Working principle: Ensure that the first column 1 is fixed on the base 2, the first fixing block 3 is fixed on the top of the first column 1, and the threaded rod 6 is rotated so that its outer thread matches the positioning hole 8. The threaded rod 6 can be rotated manually or with a tool. When the outer thread of the threaded rod 6 is aligned with the positioning hole 8, the second column 5 can be moved up and down through the thread of the threaded rod 6. When the threaded rod 6 is screwed upward, the second column 5 moves upward; when the threaded rod 6 is screwed downward, the second column 5 moves downward. The up and down movement range of the second column 5 is limited by the length of the threaded rod 6. After the second column 5 moves to the desired position, the position of the second column 5 can be fixed by tightening the first bolt 9. The first bolt 9 passes through the outer ring of the second column 5 and matches the inner thread of the fourth fixing block 10.
