The invention provides an externally connected type text shooting instrument which is provided with a shooting head part, a shooting lens arranged on the shooting head part, a bracket and a base, wherein the shooting head part is supported by the bracket and the base. The externally connected type text shooting instrument is characterized in that the bracket is a multi-stage hoisting bracket; the bottom of the bracket is provided with a foldable USB (universal serial bus) plug-in element; and the USB plug-in element is provided with a tail end with a pin hole and is rotatably hinged with a USB connector. The ratable USB plug-in element is multifunctional: firstly, when the USB plug-in element is started and is connected to an external device, the USB plug-in element can be used as an efficient fastener for stabilizing the whole device, and only a base cover is required instead of other balancing support bases, therefore simplifying the structure and reducing the weight; secondly, no other USB data line is required, and the USB plug-in element can be directly connected to the port of the external device; and finally, all the parts from the bracket to the shooting head part can be folded in a multi-section mode. The shooting instrument can be folded to a great extent and is small, simple and portable.
