[0002] At present, in the photovoltaic field, photovoltaic modules are generally installed on photovoltaic brackets. Existing photovoltaic brackets generally support multiple purlins through crossbeams. Purlins are used to connect connectors (such as middle pressure blocks and side pressure blocks) used to fix photovoltaic modules. Holes are punched on the crossbeams to connect purlin positioning parts through bolt assemblies. Purlin positioning parts are used to position the purlins. Due to the different sizes of photovoltaic modules, the spacing between adjacent purlins is different. Therefore, it is currently necessary to punch holes in the crossbeams according to the size of the photovoltaic modules used at the installation site. The punching operation is generally performed in the crossbeam production factory, which greatly affects the installation efficiency of the photovoltaic bracket.
