DETAILED DESCRIPTION OF THE EMBODIMENTS

(10) The rotatable pushing cover 7 is locked by the spring head 4 and the top support 3 and is in a closed state. At this time, the cylinder body of the rotatable pushing cover 7 is in a close contact with the hemispherical spring head 4, and the cover pushing spring 1 in the spring cap 5 is in a free opening state, as shown in FIG. 1 or FIG. 2 and FIG. 11.

(11) Since the upper surface of the rotatable pushing cover 7 is a rough surface, through manually pushing the rotatable pushing cover 7 in a horizontal direction, the rotatable pushing cover 7 slides horizontally along the horizontal sliding groove 11. Meanwhile, the rotating torsional spring 2 is pulled to generate a resilience force. When the rotatable pushing cover 7 slides to the highest point of the spring head 4, the cover pushing spring 1 is in a compression state, and the elastic force is maximum, as shown in FIG. 3.

(12) When the rotatable pushing cover 7 slides over the highest point of the spring head 4, the snap-fit block 72 is separated from the cigarette case snap-fit hole 10 at this time, as shown in FIG. 4 or FIG. 5 and FIG. 12. In this case, the rotating torsional spring 2 is in a tension state, and the resilience force is maximum. Since the snap-fit block 72 is separated from the cigarette case snap-fit hole 10, the rotating torsional spring 2 drives the rotatable pushing cover 7 to rotate, the maximum rotation angle can reach 90 degrees, and the rotatable pushing cover 7 reaches a free opening state, as shown in FIG. 6 or FIG. 7.

(13) The steps of closing the rotatable pushing cover 7 are as follows. The rotatable pushing cover 7 is pressed down manually. Since the upper surface of the rotatable pushing cover 7 is a rough surface, the rotatable pushing cover 7 is driven to slide reversely and horizontally, to make the snap-fit block 72 engaged with the cigarette case snap-fit hole 10, and thus closing the rotatable pushing cover 7 to present a closed state.
