This utility model relates to the field of computer storage device technology and discloses a simplified USB flash drive structure that is easy to assemble. It includes a USB flash drive body, a shell attached to the surface of the body, and mounting posts fixedly connected to the surface of the body. Through the adaptation of the mounting posts to the through-slots and the cooperation of the mounting slider and the guide rail, personnel can quickly and accurately insert the USB flash drive body into the shell for assembly, avoiding the time-consuming and labor-intensive problems caused by traditional bolt-fixed assembly. Simultaneously, by pulling the pull handle, the transmission rod and movable plate retract the limiting rod, allowing the USB flash drive body to be inserted without obstruction. The reset of the telescopic spring automatically pushes the limiting rod through the slot, achieving rapid locking of the mounting posts. This not only simplifies the assembly steps, eliminating the need for complex tools or cumbersome operations, but also significantly improves assembly efficiency, reduces production costs and labor intensity, and facilitates subsequent disassembly and maintenance.
