Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, the present invention includes a mobile phone fixed case (1), a retractable cover (2), a Fresnel lens (3) and a frame (4).

[0015] The working principle of the present invention is as follows:

[0016] The retractable cover is composed of 12 trapezoidal covers that are closely connected to each other through the teeth. It can be freely extended (shrinkable) when subjected to a large pulling (compression) force. The mobile phone fixed case is tightly connected to one of the trapezoidal covers through the locking teeth. It can also be stretched (contracted) when subjected to a large tension (compression), and the Fresnel lens is closely connected with the retractable cover through the frame. The Fresnel lens is made of PVC plastic, and the retractable cover and the phone holder are mad...
