[0002] At present, the portable foldable solar photovoltaic power generation devices on the market are not convenient enough when the user needs to fold the power generation device, and are not efficient enough when the user needs to adjust the direction of the power generation device.

[0003] To solve the above problems, there is currently a solution for a portable foldable solar photovoltaic power generation device (announcement number CN218499090U). The portable foldable solar photovoltaic power generation device, through the set limit block, the set output rod, the set extended rotating assembly and the set limit rod, can facilitate the user to efficiently store and fold its fixed base plate and solar panel, thereby meeting the user's needs for efficient folding and storage.

When the photovoltaic panel is unfolded, a pressure block is used to maintain the unfolded state of the photovoltaic panel. However, the size of the pressure block is limited. After exceeding the limit range of the pressure block, the photovoltaic panel rotates downward due to its own weight and the angle of the photovoltaic panel cannot be adjusted, resulting in a limited adjustment range and angle of the photovoltaic panel, which still needs to be improved.
