Abstract: A pressable portable storage device includes an outer housing, a main body fixedly accommodated inside the outer housing, an inner housing slidably accommodated in a sliding space between the main body and the outer housing, an elastic unit connected between the main body and the inner housing, and a linear spring. The main body has a terminal port exposed outside the outer housing. The inner wall of the outer housing is formed with a protrusion. The linear spring has a first end disposed on the inner housing and a second end formed with a guiding hook pointing toward the inner wall of the outer housing. When the inner housing slides to sleeve the terminal port, the guiding hook moves along an outer edge of the protrusion to drive the linear spring to deform for providing a first spring force, and the elastic unit deforms for providing a second spring force.
