1. A detachable backplate phone case, characterized in that: The device includes a shell body and a back panel. The back panel is detachably connected to the shell body. The shell body is a soft rubber shell. One side of the shell body has a recessed fixing groove for mounting a mobile phone. The side of the shell body opposite to the fixing groove has a mounting groove for mounting the back panel. The back panel covers the mounting groove. The back panel has a clearance hole for avoiding the mobile phone camera position. The bottom wall of the mounting groove is provided with a protective part for protecting the mobile phone camera position. The protective part is a closed ring structure that surrounds and fits the camera position. The protective part includes a fitting part that fits the camera position and an airbag part. The airbag part is located at the end of the fitting part away from the mounting groove and partially protrudes from the outer periphery of the fitting part. The back plate is integrally connected with multiple protrusions that protrude from the wall of the clearance hole. The part of the airbag part that protrudes from the outer periphery of the fitting part leaves a gap with the bottom wall of the mounting groove to form a slot for engaging the protrusions. A connecting strip is connected between adjacent protrusions. The width and thickness of the connecting strip are smaller than the width and thickness of the protrusions. The connecting strip is also engaged in the slot.
2. The detachable backplate phone case of claim 1, wherein: The multiple protrusions are evenly distributed circumferentially along the inner wall of the clearance hole.
3. The detachable backplate phone case of claim 2, wherein: The protrusion is located on one side of the patterned layer of the back plate and is an inclined guide surface.
4. The detachable backplate phone case of claim 2, wherein: The back plate has a protrusion at at least one apex corner, and the inner peripheral wall of the mounting groove has a slot corresponding to the protrusion. The thickness of the protrusion is less than the thickness of the back plate.
5. The detachable backplate phone case of claim 4, wherein: The protrusion is in the shape of an isosceles trapezoid, and the length of the side of the protrusion connected to the back plate is greater than the length of the side of the protrusion away from the back plate.
6. The detachable backplate phone case of claim 5, wherein: Two protrusions are provided, and the two protrusions are respectively located at the two top corners of the back plate near the avoidance hole.
