second body

50,51 both sides also are respectively equipped with a mounting groove 54, and a pair of accessory 6 is immobilizated in respectively in the mounting groove 54, can fix the two ends of a lanyard (not shown) on the described accessory 6 respectively and carry to make things convenient for the user.

During assembling, at first will store the module 2 and second body 51 and be installed in second inner housing 11, this moment accessory 6 will be installed on the both sides of second body 51 respectively; Secondly push rod 3 is installed in the opening 2001 and second fitting recess 513 on second body 51 on the storage module 2, slide block 310 on the described push rod 3 is positioned at described second driver slot 5130, simultaneously gear 4 is socketed on the pivot 300 on the push rod 3, at this moment, a side of gear 4 and the second tooth bar 2011 mutually interlock of storage on the module 2; Once more first body 50 and first inner housing 10 are fastened on respectively on second body 51 and second inner housing 11, at this moment, first tooth bar 1002 interlock mutually on the opposite side of described gear 4 and first body 10; At last first,

second shell body

12,13 is posted by first, second

inner housing

10,11 peripheries respectively, thereby is combined into the utility model flash memory device 8.

As Fig. 1, Fig. 8 with Figure 9 shows that the utility model flash memory device 8 push rods 3 promote plugs 22 and are hidden in or the protruding motion state diagram that exposes housing 1, in the time of in plug 22 is hidden in housing 1, slide block 310 on the described push rod 3 is positioned at the end that helicla flute (not label) is away from housing 1, at this moment, one side of described gear 4 and first tooth bar 1002 on first inner housing 10 are away from the end interlock mutually of plug 22, and second tooth bar 2011 is close to the end interlock mutually of plug 22 on the opposite side of gear 4 and the storage module 2; Because rotating mechanism 5 is to be immobilizated in the housing 1 in the utility model flash memory device 8, and rotating mechanism 5 can not move with respect to the first direction A of housing 1 along housing 1, then rotate described rotating mechanism 5 around axle center X, the helicla flute (not label) of slide block 310 on the described push rod 3 in rotating mechanism 5 travels forward with respect to housing 1 along first direction A, simultaneously, described push rod 3 driven gears 4 move forward; Because described housing 1 is static along first direction A with respect to rotating mechanism 5, then described first tooth bar 1002 with respect to rotating mechanism 5 along first direction A transfixion, described storage module 2 be positioned at housing 1 and not with housing 1 fixing, be that described storage module 2 can move along first direction A with respect to housing 1, the opposite side of described again gear 4 and the second tooth bar 2011 mutually interlock of storage on the module 2, be that described gear 4 is static with first tooth bar 1002 of one side interlock, and with its opposite side mutually second tooth bar 2011 of interlock according to the motion of gear 4 and can produce transmission, when then described push rod 3 driven gears 4 travel forward, described gear 4 can rotate forward along first tooth bar 1002, simultaneously, the rotation of gear 4 will drive second tooth bar 2011 transmission forward, then storage device 2 travels forward and drives plug 22 and moves forward with respect to housing 1, when described rotating mechanism 5 clockwise rotates 180 when spending around axle center X, described plug 22 can protrude out housing 1 fully, and described slide block 310 is held on the stop section 53 in case the non-return commentaries on classics.Static and gear 4 one sides are to rotate along first tooth bar 1002 because of first tooth bar 1002, then can first tooth bar, 1002 places as gear 4 proal motion axle center, the direction of motion of supposing push rod 3 is passed 1 G on the gear 4, then this G is identical along movement velocity and the movement travel of first direction A with push rod 3, if this G and first tooth bar 1002 are r along the distance of second direction B, promptly this G is r apart from the distance in this motion axle center, the opposite side of the gear 4 that matches with second tooth bar 2011 and the distance between this motion axle center are n times apart from r, the movement velocity that other establishes this G on the gear 4 is v, run duration is t, linear velocity formula according to the object that moves in a circle: v=2 π r/t, the movement velocity that then can draw the opposite side of the gear 4 that matches with second tooth bar 2011 is a n of the movement velocity at G place times, again according to movement travel=time * speed, because the run duration of gear 4 each points is identical, the stroke that can draw 2011 motions of gear 4 opposite side transmissions second tooth bar is some G n times along first direction A movement travel, be push rod 3 n times along first direction A move distance, thereby storage module 2 is effectively amplified along the distance that first direction A moves, thereby can reduce to promote the active force of push rod 3 motions.The direction of motion of push rod 3 is to pass the center of circle of gear 4 in the utility model flash memory device 8, and a promptly described G is gear 4 centers of circle, establishes between gear 4 centers of circle and the motion axle center apart from being R, the then proal speed v of gear 4 circle centre positions=2 π R/t; And the distance of the opposite side of gear 4 from the motion axle center is 2R, then the proal linear velocity of gear 4 opposite sides is 2 times of gear 4 circle centre position movement velocitys, the opposite side transmission second tooth bar 2011 proal speed of this gear 4 also are 2 times of circle centre position movement velocity simultaneously, in the utility model flash memory device 8 with rotating mechanism 5 around axle center X dextrorotation turnback, push rod 3 can be S along the first direction movement travel, then can draw the opposite side transmission second tooth bar 2011 proal strokes that gear 4 cooperates with second tooth bar 2011 is 2S, thereby make that the movement travel of storage module 2 is effectively amplified, this moment, plug 22 can protrude out housing 1 fully conveniently to peg graft with butt connector (not shown), as long as promptly apply the very little active force that promotes push rod 3 forward, just can make the big distance of storage device 2 motions, protrude out housing 1 thereby drive plug 22.

In addition; around axle center X 180 degree that circle round, described push rod 3 moves towards first direction A in the other direction along described helicla flutes (not shown), returns in the housing 1 thereby drive storage device 2 with described rotating mechanism 5; at this moment, plug 22 just is hidden in the housing 1 so that the purpose of good dust-proof protection to be provided.

Can draw thus, described push rod 3, first tooth bar 1002 that gear 4 and first body 10 that matches with gear 4 both sides are interior and second tooth bar 2011 on the storage device 2 are combined to form the one stroke enlarger, static relatively by first tooth bar 1002, but and second tooth bar, 2011 relative motions, thereby only need apply less moving push rod 3 small distances of trying hard to recommend, just can make gear 4 drive storage device 2 and move bigger distance by transmission second tooth bar 2011, and then the bigger distance of plug 22 motion exposes or is hidden in the housing 1, damages push rod and handled easily thereby avoid undue force to cause; In addition; the utility model flash memory device 8 is by rotating whirligig 5 fixed angles around axle center X; it in the utility model preferred embodiment the Rotate 180 degree; make the user can conveniently control rotational angle and use dynamics; driving plug 22 protrudes out or is hidden in the housing 1; do not use any dustproof accessory of formula that adds thereby can reach, can provide the good dust-proof protection to this plug, and be convenient for carrying.
