Claim:
A universal serial bus (USB) flash drive pen device, comprising: a USB plug assembly having a flash controller and a flash memory device; a pusher assembly including a rotator having one or more tabs disposed thereon; and a housing for housing at least a portion of the USB plug assembly and the pusher assembly, the housing having a tunnel and an inner tube extended from the tunnel disposed within the housing, wherein an intersection between the tunnel and the inner tube includes one or more angled corners, wherein when the USB plug assembly is deployed, the pusher assembly is pushed from a back end of the housing to deploy the USB plug assembly through a front end of the housing, wherein the rotator travels forward through the tunnel into the inner tube until tips of the one or more tabs of the rotator past the intersection of the tunnel and inner tube upon which, the tips of the one or more tabs of the rotator are interlocked with the angled corners of the intersection to maintain the USB plug assembly in a deployed position, and wherein when the USB plug assembly is retracted by pressing the pusher assembly again, the rotator rotates causing the tips of the tabs of the rotator to be unlocked from the angled corners of the intersection upon which, the rotator travels backward from the inner tube through the tunnel towards the back end of the housing, which in turn retracts the USB plug assembly into the housing.
