by arranging the compression spring 13, when the mobile phone is in a vertical state, the compression spring 13 is extruded by the mobile phone, and the compression spring 13 is in a compression state, so that if the mobile phone is dropped in the vertical direction by a user sliding the hand, one end of the installation blocking plate 12 is firstly grounded, the compression spring 13 can buffer the mobile phone, and the impact force on the mobile phone is reduced; the wear-resistant sheet 14 is used for preventing the compression spring 13 from scratching the mobile phone; the protection capability of the mobile power supply to the mobile phone is enhanced; in addition, the invention is provided with the positioning magnet 15 and the clamping magnetic ring 16; after the positioning block 7 enters the positioning slot 6, the positioning magnet 15 and the clamping magnetic ring 16 are magnetically attracted, so that the fixing buckle 5 is more stably fixed on the heat insulation plate 3, and the mobile phone is more stably protected by the fixing buckle 5; the protection capability of the mobile power supply to the mobile phone is further enhanced.

The front, the back, the left, the right, the upper and the lower are based on the observation angle of the person, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
