• and
• a second body detachably connected to the first body, the second body comprising a main functional unit;
• and
• wherein the main functional unit is detachably mounted to the frame;
• and the second body further comprises an elastic component connected to the main functional unit, the elastic component comprises an initial state and a deformed state, the elastic component is configured to generate an elastic force when in the deformed state to detach the main functional unit from the frame;
• wherein the main functional unit is a display module, and a display output area of the display module is arranged on a front side of the main functional unit;
• and
• wherein the display module comprises:
• a display assembly configured to display a first image;
• and
• a light transmission assembly configured to convert a light path of a first light beam which is emitted from the display assembly and corresponding to the first image, to form a second light beam corresponding to a magnified virtual image of the first image;
• wherein the display assembly comprises a first display area and a second display area, the first display area is configured to display the first image if the main functional unit is mounted to the frame, and the second display area is configured to display the first image if the main functional unit is detached from the frame;
