The embodiment of the invention discloses portable information conversion equipment which is configured to be in
signal connection with a terminal, and the terminal comprises a shell and a
second screen arranged on the shell. The portable information conversion equipment comprises a main body, a first screen, a communication part and a connecting part, and the communication part is used for forming
signal connection with a terminal so that the first screen can be in
butt joint with the terminal and information display can be achieved; the connecting part is used for detachably connecting the main body to the shell, and the first screen and the
second screen can face different directions. Therefore, the main body can be detachably connected to the shell of the terminal through the connecting part, so that the portable information conversion equipment and the terminal can be conveniently, quickly and simply assembled, and the integrated
electronic equipment is formed, thereby being convenient for a user to carry and use. And when the portable information conversion equipment needs to be independently used, the portable information conversion equipment can be conveniently detached from the shell of the terminal, so that the portable information conversion equipment can be conveniently applied to different application scenes.
