Similarly, when the user operates the display fixing base 4 to rise, the elastic force of the elastic member 3 changes with the rising force required by the display fixing base 4. No matter how much the display fixing base 4 rises, the operating force required by the user remains unchanged, which greatly enhances the user's operating experience and makes it easier for the user to operate.
