[0074] Exemplarily, the following describes the process of using the pressing piece 2 to press the photovoltaic frame 200 in the limiting groove 104 in combination with the accompanying Figures 1 to 4

[0075] ​Firstly, the pressing plate 201 of the pressing part 2 is placed above the bottom plate 101, the bottom plate 101 is parallel to the pressing plate 201, the first connecting hole 202 on the pressing plate 201 is aligned with the connecting hole on the bottom support part 1 or the purlin 100, the first fixing part 204 (such as a bolt, a nut or the like) is used to pass through the first connecting hole 202 on the pressing plate 201, and the bottom support part 1 or the purlin 100 is connected, so that the pressing plate 201 presses the top of the photovoltaic frame 200 in the two limiting grooves 104, and the two side plates 203 of the pressing part 2 are correspondingly located above the first support plate 102, and the outer side of the photovoltaic frame 200 in the limiting groove 104 is supported.

[0076] That is, through the cooperation of the pressing plate 201 and the side plate 203, the pressing plate 201 applies downward pressure, the two side plates 203 support the displacement of the outer side of the photovoltaic frame 200, the pressing part 2 can double-fix the photovoltaic frame 200 from the top and the outer side, ensure the stability of the photovoltaic module after installation, and prevent loosening or falling off due to external forces such as wind pressure and snow pressure. In addition, the two side plates 203 can also assist the pressing part 2 to quickly position, and simplify the installation process.

[0077] In some embodiments provided by the utility model, as shown in Figures 1 to 15 The first fixing part 204 is connected with the purlin 100, and the bottom support part 1 further comprises a connecting plate 106, the connecting plate 106 is located between the two first support plates 102 and connected with the two first support plates 102 respectively, and the connecting plate 106 is parallel to the bottom plate 101 and located between the bottom plate 101 and the pressing part 2.
