Connecting pieces 1-1-1, 1-2-1 and 1-3-1 are set on both sides of the bottom plate 1-1, the left baffle 1-2 and the right baffle 1-3.

[0027] In this embodiment, the left baffle 1-2 and the right baffle 1-3 are respectively connected to the left swing cover 1-4 and the right swing cover 1-5, and the size of the left swing cover 1-4 and the right swing cover 1-5 is 1 / 2 of the bottom plate 1-1.

[0028] Connecting pieces 1-4-1 and 1-5-1 are arranged on both sides of the left swing cover 1-4 and the right swing cover 1-5.

[0029] The solid lines at the edges of the figure are contour lines, and the solid lines inside are fold lines, which are formed by pressing.

[0030] All connecting pieces have the same width (vertical length of the connecting piece in the figure), and the width is about 1 / 6 of the height of the packaging box.

[0031] The left baffle connecting piece 1-2-1 is the same length as the left baffle 1-2, the right baffle connecting piece 1-3-1 is the same length as the right baffle 1-3, and there is a spacing between the bottom plate connecting piece 1-1-1 and the left baffle connecting piece 1-2-1 and the right baffle connecting piece 1-3-1, and the spacing is equal to the width of the connecting piece; similarly, the spacing between the left rocker cover connecting piece 1-4-1 and the left baffle connecting piece 1-2-1 is equal to the width of the connecting piece, and the spacing between the right rocker cover connecting piece 1-5-1 and the right baffle connecting piece 1-3-1 is equal to the width of the connecting piece.
