Abstract

The invention includes a box body ( 1 ), a cigarette outlet ( 10 ), a mechanism ( 2 ) and a cigarette-pushing mechanism ( 3 ). The cigarette-pushing mechanism ( 3 ) includes a bottom plate ( 30 ), a V-shaped bend ( 31 ) and a U-shaped cigarette-pushing plate ( 32 ). One end of the V-shaped bend ( 31 ) is movably fixed on the cigarette-pushing plate ( 32 ), and the other end of the V-shaped bend ( 31 ) is movably fixed on the bottom plate ( 30 ). A snap-fit ( 33 ) is provided on the bottom plate ( 30 ), and a groove ( 34 ), through which the snap-fit ( 33 ) passed, is provided on the cigarette-pushing plate ( 32 ). The bottom plate ( 30 ) and the cigarette-pushing plate ( 32 ) form an integrated structure through the engagement of the snap-fit ( 33 ) and the groove ( 34 ). The cigarette outlet ( 10 ) is provided with an elastic plastic sheet for dustproof and moisture proof.
