Photovoltaic modules are laid on the outer surface of the building structure to provide electricity. The solar power generation system is integrated with roofs, skylights, curtain walls and other buildings to build green and environmentally friendly houses. Photovoltaic panel components are a power generation device that generates direct current when exposed to sunlight. They are composed of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Solar photovoltaic panel components are usually installed on the top of photovoltaic buildings, and mounting brackets are generally used to support and fix the photovoltaic panels.

[0003] For example, the "Photovoltaic Building Fixing Device" disclosed in patent publication number CN218387340U is fixedly connected to the lower outer surface of the solar panel through the side ear plate, and the lower outer surface of the fixing block is fixedly connected to the upper outer surface of the mounting rod. During installation, the limiting column is squeezed to make the limiting column slide along the slide groove, so that the limiting column squeezes the second compression spring inside the slide groove, and then the insert block is inserted into the slot. When the limiting column reaches the position of the limiting hole, the second compression spring is reset, so that the limiting column and the limiting hole are clamped and fixed to complete the installation.

[0004] However, in actual use, the clamping assembly on the mounting rod of the above structure is a fixed structure and cannot be adjusted in position. Therefore, the spacing between the mounting assemblies cannot be adjusted according to the width of the photovoltaic panels to be installed, which limits the scope of application of the fixing device.
