Further, the first connecting portion 4031 and the second connecting portion 4032 are further provided with a plurality of threaded holes 445 and an avoiding step 446, so that the bending effect and performance of the foldable notebook are effectively improved.

Further, in the embodiment of the present invention, the first host housing 111 may be disposed at one side of the second host housing 112, and the first host housing 111 and the second host housing 112 may be separated from each other. The multifunctional operation of the folding notebook is realized by arranging the first and second

main body housings

111 and 112 in a separable and splittable structure.

Specifically, when the first host housing 111 is combined with the second host housing 112, which corresponds to the structure of the host housing in fig. 1, the host housing 10 has a larger expansion area.

Specifically, in the embodiment of the present application, both the first and second

main chassis housings

111 and 112 can be folded in a plurality of different directions. Specifically, in the embodiment of the present application, the first main housing 111 can be folded in two different directions, i.e., the first direction X1 and the second direction Y1, relative to the second main housing 112.

The first direction X1 and the second direction Y1 are two different folding directions. If the first direction X1 is a horizontal folding direction, the second direction Y1 is a vertical folding direction. By folding the first main body case 111 and the second main body case 112 in two different directions, the size of the folded notebook is reduced and portability of the apparatus is achieved.

Specifically, referring to fig. 3 in detail, in the first direction X1, within a plane formed by the main housing, such as a horizontal plane, since the first main housing 111 is detachably and movably connected to the second main housing 112, the first main housing 111 can be folded with respect to the second main housing 112 along the first direction X1.

With specific reference to fig. 6, fig. 6 is a schematic plan view of the main housing according to the embodiment of the present disclosure. A plane O formed on the main unit casing ₁ O ₂ In the first state, the first and second

main chassis
