Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0016] Example 1 like Figure 1 , Figure 3As shown, a device for fastening accessories for photovoltaic brackets includes a first support frame 1, with a first sliding groove 2 inside the first support frame 1. The first support frame 1 has a U-shaped structure, and the first sliding groove 2 extends horizontally through the first support frame 1. The first support frame 1 facilitates cooperation with other brackets for overall installation, and the cooperation between the first support frame 1 and the first sliding groove 2 facilitates the subsequent movement of components on the first sliding groove 2, making it convenient to fix the photovoltaic panel (not shown in the figure) laterally.

[0017] like Figure 1 , Figure 2 and Figure 4 As shown, a fastening assembly 5 is provided inside the first slide groove 2. The fastening assembly 5 includes a slider 501 that is slidably connected to the inner wall of the first slide groove 2. A second support frame 502 is fixedly connected to the upper surface of the slider 501. The second support frame 502 is U-shaped to facilitate subsequent positioning of the photovoltaic panel. The second support frame 502 is slidably connected to the upper surface of the first support frame 1. By sliding the slider 501 in the first slide groove 2, the second support frame 502 is moved, facilitating subsequent fixation of the photovoltaic panel position by the second support frame 502. A second bolt 503 is threaded through the upper surface of the second support frame 502. A pressure plate 504 is rotatably connected to the bottom of the second bolt 503. By rotating the second bolt 503, the position of the pressure plate 504 is changed. By adjusting the position of the pressure plate 504, it is convenient to adjust the position of photovoltaic panels of different thicknesses. To prevent the photovoltaic panel from shifting during operation, the upper surface of the pressure plate 504 is provided with several bases 505 fixedly connected by screws. The screws facilitate the installation and replacement of the bases 505. Each of the bases 505 has a spring 506 fixedly connected to the top of the inner wall of the second support frame 502. In this embodiment, there are two bases 505 and two springs 506. The specific number can be changed according to the actual situation. The bases 505 are located on both sides of the second bolt 503. The bases 505 and the springs 506 are integrally set. The springs 506 are initially in a compressed state. By changing the position of the pressure plate 504, the length of the springs 506 is changed. The springs 506 press down on both sides of the pressure plate 504 to prevent the ends of the pressure plate 504 from tilting up and affecting the fixing effect of the pressure plate 504.

[0018] like Figure 1 , Figure 2 As shown, the bottom of the first support frame 1 is provided with a second slide groove 3, which is located directly below the slider 501. The slider 501 is T-shaped, and the bottom of the slider 501 abuts against the top of the first bolt 4. By using a wrench or other tools to rotate the first bolt 4, the bottom of the first bolt 4 abuts against the bottom of the first support frame 1. The bottom of the slider 501 is provided with a threaded hole. Then, the top of the first bolt 4 is threadedly connected to the threaded hole at the bottom of the slider 501 to fix the position of the slider 501 and prevent the position from shifting during subsequent operation.
