Most endoscopes maintain operating temperatures by sacrificing image performance and reducing power consumption. Summary of the Invention

[0009] Furthermore, the mounting hole and the pressing surface on the heat conducting plate pressing block are connected by cantilever structures on both sides, and the heat conducting plate passes between the cantilever structures on both sides. The cantilever structures are used to bear the main pressure of the heat conducting plate pressing block.
