[0046] Through the bending change of the inner layer 31, it meets the switching between the folding state and the unfolded state of the cooperative electronic device 5, avoiding the influence of the protective shell on the use of the electronic device 5. At the same time, by using the inner layer 31 to form a pulling force, the pulling force acts on the first middle cover 1 or the second middle cover 2, facilitating the swinging and resetting of the first middle cover 1 or the second middle cover 2, and thus facilitating the switching between the unfolded state and the folding state of the first middle cover 1 and the second middle cover 2.
