At the same time, in order to reduce the drop of the mobile phone and increase the anti-slip ability of the mobile phone case, anti-slip structures 2 are provided on the lower part of both sides of the case 1. Then, speaker holes 13 are opened on both sides of the top of the case 1. The speaker holes 13 are not only a channel for the mobile phone speaker to play, but also a channel for the mobile phone infrared to use externally. Then, in the middle of the bottom end of the case 1, a speaker hole 13 is opened. The speaker hole 13 is not only a channel for the mobile phone speaker to play, but also a channel for the mobile phone infrared to use externally. A charging port 14 is opened, and a second speaker hole 15 is opened on one side of the bottom end of the shell 1. Then, in order to prevent the phone from falling, silicone pads 19 are fixedly connected to the four top corners of the inner wall of the shell 1. When the phone falls together with the phone case, the four silicone pads 19 can well protect the four corners of the phone. Then, a rotating block 3 is rotatably connected to the middle of the top end of the shell 1, and the rear end of the bottom end of the rotating block 3 is fixedly connected to the back cover 4. Here, in order to fix the back cover 4 on the shell 1 well, a fixing groove 9 is first opened on the side of the bottom end of the shell 1 away from the second speaker hole 15, and then a fixing block 10 is fixedly connected to the middle of the top wall of the fixing groove 9. At the same time, a fixing plate 11 is fixedly connected to the bottom of the front end of the back cover 4 with the fixing groove 9. It should be noted that the fixing plate 11 has a certain elasticity, and a positioning hole 12 is opened in the middle of the top of the fixing plate 11. After the mobile phone is placed in the mobile phone case, it is only necessary to rotate the back cover 4 to a position parallel to the shell 1, and then put the fixing plate 11 into the fixing groove 9. Finally, the fixing block 10 is connected to the positioning hole 12 to complete the fixing of the back cover 4 on the shell 1. Then, a lens hole 5 is opened on one side of the upper front end of the back cover 4 near the speaker hole 2 15. At the same time, a lens hole 5 is fixedly connected to the rear end of the back cover 4. A lens frame 18 is used in conjunction with the lens hole 5 to protect the lens of the mobile phone. A number of heat dissipation holes 6 are opened on the side of the upper front end of the back cover 4 away from the lens hole 5. In addition, a fixing hole 7 is opened at the lower part of the front end of the back cover 4, and a replaceable back plate structure 8 is provided in the fixing hole 7. At the same time, in order to better transfer the heat of the mobile phone, a heat spreader 17 is fixedly connected to the front end of the back cover 4. It should be noted here that the heat spreader 17 is fixed to the back cover 4 by glue. The user can easily remove it and replace it with a new back plate structure 8, and the heat spreader 17 will not block the lens hole 5.
