Embodiment

Fig. 2,3 is that movable case of the present utility model is with flash cell, the perspective exploded view of spring arm and two spring combinations and the schematic perspective view of combination, as shown in the figure, (seeing Figure 4 and 5) movable case 30, its two side is convexly equipped with protruding rail 30a, and be provided with groove 301 at its front end, be used for fixing flash cell 40, rear at groove 301 also is provided with build-in unit 31, be provided with two recess 311a and a recessed caulking groove 311 in its back-end, be used for the slotting portion 501 of spring arm body 50 is inserted fixed bit, be respectively equipped with projection 312 in the both sides of movable case, be used for inserting spring 60 solid; (seeing Fig. 6,7,8 and 9) rail housing 70, in the middle of it is the groove shape, be concaved with recessed rail 702 in its two side, be used for plugging together with the protruding rail 30a of movable case 30, it can be moved back and forth betwixt, convex with two protruding rails 701 that are provided with at interval in the centre, be used for matching with two recess 311a of the build-in unit 31 of movable case 30, can be back and forth movable thereon, in addition, front end 701 of two protruding rails is provided with movable rail 703, and it becomes Y shape, is used to guide the movable betwixt and location of top dog 503 of spring arm body 50 front ends; In addition, the dual-side of two protruding rails 701 is formed with groove, is used to make spring 60 to be arranged on telescopic movable therebetween.

As shown in Figure 8, the movable rail 703 of rail housing 70 along inclined direction extends to a place by initial part 703a, goes into recess down to back bending then, form location division 703b, extend to initial part 703a direction, it comprises pars convoluta 703c midway again, extends back initial part 703a then.

As shown in Figure 2, described spring arm body 50 is made by the elasticity material, and the front end of spring arm 502 is bent to form top dog 503, and its end is bent to form the portion 501 that inserts.

Fig. 9 is the enforcement action schematic perspective view of the improved USB flash disk connector extending and contracting of the utility model device; as shown in the figure; the top dog 503 of spring arm 502 front ends of spring arm body 50 is positioned at the initial part 703a of the movable rail 703 of rail housing 70; drive spring arm body 50 by preceding pushing away movable case 30; the compression spring 60 thereby flash cell 40 marches forward; wherein; the top dog 503 of spring arm 502 front ends of spring arm body 50 is before the guiding of movable rail 703 and then go into 703b hook location, recessed location division; thereby the USB connector of the flash cell 40 of its movable case 30 front ends can be protruded with computer and plug together; contract in when not using when hiding USB connector with protection flash cell 40; thereby need only before push away top dog 503 that movable case 30 drives spring arm 502 front ends of spring arm bodies 50 and advance and break away from location division 703b; the elasticity of spring arm 502 bodies of this spring arm body 50 former plumbness of just can rebounding automatically; simultaneously; the 60 suffered compressions of two springs are released and form bounce at this moment; the movable case 30 of pushing tow is return the location after automatically; wherein; spring arm body 50; flash cell 40 also retreats together; the top dog 503 of spring arm 502 front ends of this spring arm body 50 just can cushion the bounce of a lower spring 60 earlier earlier by the pars convoluta 703c of movable rail 703; and then return initial part 703a and locate; thereby promptly reach the effect of the USB connector of scalable hiding protection flash cell 40, dwindled the volume of USB flash disk again.

The above is a preferred embodiment of the present utility model, according to the change that design of the present utility model has been done, when its function and effect do not exceed spiritual that specification of the present utility model and accompanying drawing contain, must belong to scope of the present utility model.
