[0027] As shown in the sectional view of the C-purlin 1, the C-purlin 1 is provided with an upper opening, the width of the opening is smaller than the inner width, and the two sides of the upper opening of the C-purlin 1 are provided with downwardly extending flanges 11 for strengthening the opening position and positioning the mounting plate 3 to prevent rotation.

[0028] As shown in the sectional view of the C-purlin 1, the C-purlin 1 is provided with an upper opening, the width of the opening is smaller than the inner width, and the two sides of the upper opening of the C-purlin 1 are provided with downwardly extending flanges 11 for strengthening the opening position and positioning the mounting plate 3 to prevent rotation.

[0029] As shown in the sectional view of the C-purlin 1, the C-purlin 1 is provided with an upper opening, the width of the opening is smaller than the inner width, and the two sides of the upper opening of the C-purlin 1 are provided with downwardly extending flanges 11 for strengthening the opening position and positioning the mounting plate 3 to prevent rotation. Figure 7 As shown in the sectional view of the C-purlin 1, the C-purlin 1 is provided with an upper opening, the width of the opening is smaller than the inner width, and the two sides of the upper opening of the C-purlin 1 are provided with downwardly extending flanges 11 for strengthening the opening position and positioning the mounting plate 3 to prevent rotation.

Since the mounting plate 3 is not in contact with any parts at this time, it is not subject to external force. Therefore, the mounting plate 3 can also be rotated 90 degrees by rotating the fastening screw 4. Then pull the fastening screw upward to engage the slot 31 on the upper surface of the mounting plate 3. On the folded edge 11 of the C-shaped purlin 1, so that the mounting plate 3 cannot rotate, the upper pressure member 2 is moved vertically along the purlin (or along the length of the side of the photovoltaic panel), so that the long slot 24 is locked on the fastening screw 4. At this time, the pressure plate 23 is above the photovoltaic panel. The washer 4 is placed in the positioning countersunk hole 25, and the fastening screw 4 is tightened to achieve the pressing of the photovoltaic panel. Since the washer 4 is located in the positioning countersunk hole 25, the fastening screw 4 cannot come out of the long slot 24, thus ensuring the stability of the structure.
