[0038] Secondly, in this embodiment, the first side cover plate 22 is connected to the cover plate 21, and the first side cover plate 22 is folded along the sixth fold line 211. The center of the first side cover plate 22 is provided with a circular opening 224, and the first side cover plate 22 is provided with a ninth fold line 221 along the axis of the opening 224. The first side cover plate 22 is folded along the ninth fold line 221 to form a double-layer structure, and after folding, the opening 224 forms an arc-shaped notch.
[0039] The second side cover plate 23 and the third side cover plate 24 are connected to the cover plate 21, and the second side cover plate 23 and the third side cover plate 24 are folded along the seventh fold line 212 and the eighth fold line 213, respectively. In addition, the second side cover plate 23 and the third side cover plate 24 are respectively provided with the tenth fold line 231 and the twelfth fold line 241, and the second side cover plate 23 and the third side cover plate 24 are folded along the tenth fold line 231 and the twelfth fold line 241, respectively, to form a double-layer structure.
[0040] The second side cover plate 23 and the third side cover plate 24 are respectively provided with a first support plate 232 and a second support plate 242. The first support plate 232 and the second support plate 242 are folded along the eleventh fold line 233 and the thirteenth fold line 243, respectively. After the first side cover plate 22, the second side cover plate 23 and the third side cover plate 24 are closed, the first side cover plate 22 is folded along the ninth fold line 221, and the first support plate 232 and the second support plate 242 are stacked on top of it.
[0041] The first side cover plate 22 is provided with a fourth insertion part 222 and a fifth insertion part 223. After the first side cover plate 22, the second side cover plate 23 and the third side cover plate 24 are closed, the fourth insertion part 222 and the fifth insertion part 223 are respectively inserted into the double-layer structure formed by folding the second side cover plate 23 and the third side cover plate 24.
[0042] In this embodiment, the first support plate 232 and the second support plate 242 are provided with semi-circular notches, which, when combined, form a notch corresponding to the arc-shaped notch on the first side cover plate 22.
[0043] In addition, in this embodiment, the first side cover plate 22 is also provided with a second adhesive part 225. The first side cover plate 22 is folded along the ninth fold line 221, and the first support plate 232 and the second support plate 242 are stacked thereon.

Usually, since the fourth insertion part 222 and the fifth insertion part 223 are small in size, the second side cover plate 23 and the third side cover plate 24 can be directly glued by the third adhesive part 234 and the fourth adhesive part 244 after folding, without having to be glued to the cover plate 21.
[0045] In some other embodiments, if the second side cover plate 23 and the third side cover plate 24 are respectively provided with a first support plate 232 and a second support plate 242, the first side cover plate 22 does not have a fourth insertion part 222 and a fifth insertion part 223. Instead, the first side cover plate 22 is folded along the ninth fold line 221, and the first support plate 232 and the second support plate 242 are stacked on top of each other for connection. In this case, the first support plate 232 and the second support plate 242 can also avoid obscuring the arc-shaped notch during the stacking process by reducing their size, without having to provide a corresponding semi-arc-shaped notch.
[0046] Meanwhile, in other embodiments, if the first side cover plate 22 is provided with a fourth insertion part 222 and a fifth insertion part 223, the second side cover plate 23 and the third side cover plate 24 are not provided with a first support plate 232 and a second support plate 242 respectively. They are connected by inserting the fourth insertion part 222 and the fifth insertion part 223 into the double-layer structure formed by folding the second side cover plate 23 and the third side cover plate 24 respectively.
[0047] The above description is only a preferred embodiment of the present utility model. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
