7. The display device for dynamic monitoring of the power auxiliary service market according to claim 6, characterized in that: Two clamping rings (25) are sleeved on the column (10). The two clamping rings (25) are arranged opposite to each other along the axial direction of the column (10). A clamping gap (63) is formed between the two clamping rings (25). The clamping gap (63) is used to accommodate the clamping part (24). The two clamping rings (25) can be arranged to move toward or away from each other along the axial direction of the column (10) to adjust the size of the clamping gap (63) so that each clamping ring (25) abuts against the clamping part (24).

8. The display device for dynamic monitoring of the power auxiliary service market according to claim 7, characterized in that: The column (10) is provided with a first transmission groove (60), and a second transmission screw (61) and two third transmission blocks (62) are provided in the first transmission groove (60). The two third transmission blocks (62) and the two clamping rings (25) are provided in a one-to-one correspondence, and each of the third transmission blocks (62) is connected to the corresponding clamping ring (25). Each of the third transmission blocks (62) can be movably sleeved on the second transmission screw (61), and the second transmission screw (61) extends along the axial direction of the column (10). The second transmission screw (61) is rotatably provided around the axis of the second transmission screw (61) to drive the two third transmission blocks (62) to move toward or away from each other along the axial direction of the column (10).

9. The display device for dynamic monitoring of the power auxiliary service market according to claim 1, characterized in that: There are multiple first support frames (20) and multiple second support frames (30), and the multiple first support frames (20) and the multiple second support frames (30) are arranged in a one-to-one correspondence. The multiple first support frames (20) are arranged in sequence along the circumferential direction of the column (10), and any two adjacent first support frames (20) are connected to each other.

10. The display device for dynamic monitoring of the power auxiliary service market according to claim 1, characterized in that: A magnetic strip is provided on the first connecting column (22) of each of the first supporting frames (20), and the magnetic strip extends along the extension direction of the first connecting column (22). The magnetic properties of the magnetic strips on the first connecting columns (22) of any two adjacent first supporting frames (20) are opposite, so that the first connecting columns (22) of any two adjacent first supporting frames (20) are magnetically connected.
