A portable storing device with universal serial bus (USB) mainly includes an upper cover, a lower cover, a circuit board, and a push-pull control unit. The upper cover is provided with hooks to engage with catches on the lower cover to form a box, in which the circuit board is located. When the push-pull control unit is extended into the upper cover to engage with and move the circuit board forward to project a USB connecting terminal on the circuit board from a front end of the box, a hooking portion on the push-pull control unit engages with a catch below the upper cover to hold the USB connecting terminal to the projected position on the box.
