C) according to the mobile phone shell, a power supply and matched electronic elements are arranged in the plate-shaped block (2), and the barrel (18) is also arranged at the rear side of the shell body (1), so that the weight at the rear of the mobile phone shell is larger than that at the front, the probability of landing the back of the mobile phone shell is increased, the probability of screen falling down is reduced, the electronic elements are flatly arranged in the plate-shaped block (2), and the thickness of the whole mobile phone shell is reduced;
D) one side that shell body (1) was kept away from in board type piece (2) still is equipped with four elastic support rod (3), when needing to support the cell-phone, push away through removing and draw piece (12), can drive type of falling L stopper (10) and remove, thereby remove the limiting displacement to fixture block (11), in the effect of first spring (7), promote to remove short column (4) and remove, remove short column (4) and drive four elastic support rod (3) through four connecting rod (9) and remove, form supporting frame structure, this supporting frame structure plays supporting role in a plurality of directions cell-phone.
