Abstract: A protective cover unfolding and positioning device has a position restoring element installed at a folding portion adjacent to upper and lower support portions of a first protective plate for providing a restoring resilience for bending or folding the upper and lower support portions. A telecommunication product or an electronic device may be disposed obliquely on a peripheral surface of a second protective plate peripheral surface, The weight of the telecommunication product or electronic device exerted on the first protective plate upper, the lower support portions and the restoring resilience provided by the position restoring element to the upper and lower support portions Maintain stability of the that the telecommunication product or electronic device.

Abstract: An improved protective cover includes a first protective board and a second protective board coupled to each other, and foldable and unfoldable with respect to each other, and the first protective board being provided for carrying and positioning a telecom product, characterized in that the first protective board includes at least one transverse folding portion formed on a peripheral surface of the first protective board for separating the first protective board into an upper support portion and a lower support portion; and the second protective board includes at least one transverse positioning slot formed on a peripheral surface of the second protective board. Therefore, when the second protective board is folded and buckled to the first protective board, the telecom product placed on the first protective board is protected.
