[0011] The present invention is further configured such that: anti-slip stripes are provided on the side of the sliding piece away from the lens groove.

[0012] By adopting the above technical solution, friction is increased, which facilitates the sliding of the anti-slip stripes inside the outer groove.

[0013] The present invention is further configured such that a button slot is provided on one side of the exterior of the phone case body.

[0014] Using the above technical solution, the power switch and volume buttons on the side of the phone can be inserted into the button slot.

[0015] The present invention is further configured such that a charging slot and a speaker hole are respectively opened on the side of the phone case body away from the lens slot.

[0016] The above technical solution facilitates the connection of the charger to the phone's charging port and the output of sound from the phone through the charging slot and speaker hole.

[0017] In summary, the present invention has the following beneficial effects:

[0018] 1. When a phone call comes in, the RF antenna inside the phone case receives the call signal, and the MCU chip activates an LED light to alert the user. This provides call notification, allowing the phone to detect incoming calls promptly.

[0019] 2. By sliding the sliding piece inside the outer groove, the sliding piece covers the phone lens inside the lens slot and is magnetically secured by a magnetic strip, thus protecting the phone lens.
