[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a foldable back stand for smartphones, including a phone body 1 and a phone back cover 3. Edge protection pads 2 are fixedly connected to the four corners of the phone body 1 and the phone back cover 3, and the edge protection pads 2 serve to buffer and prevent slipping. A storage ring 4 is detachably connected to the back of the phone back cover 3, which facilitates the storage and folding of the stand. The back of the storage ring 4 is threadedly connected to the back of the phone back cover 3 by screws 8. The threaded connection ensures the stability and detachability of the storage ring 4. A folding storage component is provided on the storage ring 4, and an elastic positioning component is provided between the annular support frame 5 and the annular storage groove 9.

[0028] Reference Figure 3 , Figure 4 The folding storage component includes a slider 6, which is arc-shaped to facilitate sliding on a storage ring 4. An annular storage groove 9 is provided on the back of the storage ring 4, and an annular limiting groove 10 is provided on the inner wall of the annular storage groove 9 to limit the sliding trajectory of the slider 6. The outer wall of the slider 6 is slidably connected to the inner wall of the annular storage groove 9. A shaft 13 is rotatably connected through the side of the slider 6, and an annular support frame 5 is fixedly connected to both ends of the shaft 13. The annular support frame 5 supports the main body of the mobile phone 1, and a dial 7 is fixedly connected to the top of the annular support frame 5 to facilitate user operation of the rotation of the annular support frame 5. The outer wall of the slider 6 is slidably connected to the inner wall of the annular limiting groove 10 via a limiting block 15. The outer surface of the annular support frame 5 contacts the inner wall of the annular storage groove 9. The surface of the shaft 13 contacts the inner wall of the slider 6 via a rubber sleeve 14, and the inner side of the rubber sleeve 14 is fixedly connected to the surface of the shaft 13. The rubber sleeve 14 increases friction, allowing the annular support frame 5 to be stably fixed in the desired position.

[0029] Reference Figures 5-6 The elastic positioning component includes a movable groove 16, which is located on the top of the limiting block 15. The inner wall of the movable groove 16 is elastically connected to a positioning ball 12 via a spring 17.
