A spring 25 is fixedly connected between the two positioning seats 21, and the guide seat 26 slides left and right in a limited manner inside the positioning seat 21, further playing a fixing role after it is unfolded and positioned to prevent its position from shaking, and the positioning seats 21 squeeze each other, and the position of the positioning seat 21 is also positioned by its sliding limit.

[0027] Furthermore, adjustment holes are evenly opened on the outer wall of the column 1, and the outer wall of the column 1 is connected to the positioning plate 11 by screws, and the positioning plate 11 is provided with positioning holes adapted to the adjustment holes. Through this position adjustment processing, the support angles of the support tube 12 and the support rod 13 can be adjusted, thereby achieving the optimal support angle adjustment according to needs.

[0028] Furthermore, the outside of the positioning plate 11 is hinged with a support tube 12, and the inside of the support tube 12 is inserted with a support rod 13. A threaded hole is opened on one side of the support tube 12, and the internal thread of the threaded hole is provided with a bolt. The support tube 12 and the support rod 13 are connected by threaded extrusion, so that the length of the support tube 12 and the support rod 13 can be flexibly adjusted, thereby realizing adaptive adjustment of the support angles of the short cross bar 3 and the long cross bar 32 by adjusting the support lengths on both sides differently.

[0029] Furthermore, two adjusting cross bars 31 are inserted into the interior of the short cross bar 3 , and the two adjusting cross bars 31 are symmetrically distributed on both sides of the short cross bar 3 , and a support rod 13 is hinged at the bottom of one end of the adjusting cross bar 3 away from the short cross bar 3 .

[0030] Furthermore, an adjustment hole is provided on the adjustment cross bar 31, a positioning hole is provided on the short cross bar 3, and a bolt is passed through the positioning hole and the adjustment hole.

When using the utility model, the device is first assembled, and before installing the photovoltaic panels, the support angles of the short cross bars 3 and the long cross bars 32 are adjusted.
