[0023] Specifically, both the first housing 101 and the second housing 102 are provided with placement slots that match the electrode 104. Buttons 200 are provided on both sides of the first housing 101. The buttons 200 are slidably connected within the first housing 101. A first spring 201 is provided between the button 200 and the first housing 101, with both ends of the first spring 201 fixedly connected to the button 200 and the first housing 101, respectively. A connecting rod 202 is rotatably connected to the button 200, and a fourth rotating shaft 204 is rotatably connected to the end of the connecting rod 202 away from the button 200. A fifth rotating shaft 204 is provided inside the first housing 101. A fifth rotating shaft 205 is rotatably connected to a first limiting rod 203. A fourth rotating shaft 204 is fixedly connected to the first limiting rod 203. A slider 209 is slidably connected inside the second housing 102. A rubber pad 207 is fixedly connected to the upper end face of the slider 209. A second spring 208 is provided between the slider 209 and the second housing 102. The two ends of the second spring 208 are fixedly connected to the second housing 102 and the slider 209, respectively. A second limiting rod 206 is fixedly connected to the lower end face of the slider 209. The second limiting rod 206 matches the first limiting rod 203.

[0024] Specifically, the radius of the rubber pad 207 is larger than the radius of the pore 105, the radius of the slider 209 is smaller than the radius of the pore 105, and the pore 105 matches the rubber pad 207.

[0025] Specifically, it also includes a mobile phone 109, which can be installed on a first housing 101 and a second housing 102. A limiting block 302 is slidably connected to one end of the second housing 102 away from the second rotating shaft 107. A third spring 301 is provided between the limiting block 302 and the second housing 102. The two ends of the third spring 301 are respectively fixedly connected to the limiting block 302 and the second housing 102. The limiting block 302 matches the mobile phone 109.

[0026] Working principle:

[0027] When the device is in use, the second housings 102 on both sides of the first housing 101 are folded upwards. At this time, the torsion springs fixed on the second rotating shaft 107 and the third rotating shaft 108 accumulate elastic potential energy. When the second housing 102 is fully folded, the second housing 102 is in contact with the upper surface of the first housing 101. At this time, the rubber pad 207 is pressed, causing the slider 209 to push the second limiting rod 206 downwards. As the second limiting rod 206 moves downwards, it presses the upper surface of the first limiting rod 203, causing the first limiting rod 203 to rotate along the fifth rotating shaft 205. When the second limiting rod 206 continues to move downwards, the first limiting rod 203 automatically resets under the push of the connecting rod 202. The first limiting rod 203 and the second limiting rod 206 limit each other, that is, the second housing 102 is fixed. At this time, the device can be used as a charging head.

[0028] After the device is used, the buttons 200 on both sides of the first housing 101 can be pressed. At this time, the buttons 200 drive the connecting rod 202 to move towards one end of the first limiting rod 203. At this time, the first limiting rod 203 rotates along the fifth rotating shaft 205. As the first limiting rod 203 rotates, the second limiting rod 206 loses its limiting function with the first limiting rod 203. At this time, the second limiting rod 206 moves upward and resets under the action of the second spring 208. At this time, the second housing 102 unfolds to both ends under the action of the torsion springs on the second rotating shaft 107 and the third rotating shaft 108. At this time, the electrode 104 is pressed, causing the electrode 104 to rotate along the first rotating shaft 103 to the matching placement groove, and pressing the hole 105 on the electrode 104 into the rubber pad layer 207. At this time, the rubber pad layer 207 limits the electrode 104. At this time, the device is in a flat shape and can be placed in a pocket or wallet for easy carrying.

[0029] When it is necessary to fix the device to the back of the phone, pull the limiting blocks 302 on both sides of the second housing 102 and insert the phone along the slot of the limiting block 302. At this time, the device is fixed to the back of the phone. The user can pry out the electrode 104 to act as a phone stand as needed.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
