The third connecting block is rotatably connected to the circumferential outer wall of the rotating shaft. A second connecting block is fixedly connected to one side of the third connecting block. The bottoms of the second connecting block and the third connecting block are fixedly connected to the same fourth connecting block. One side of the fourth connecting block is fixedly connected to one side of the transparent waterproof cover. An inner sleeve is fixedly connected to the circumferential interior of the second connecting block. A first connecting block is slidably connected to the circumferential outer wall of the inner sleeve. A handle is rotatably connected to one side of the first connecting block. The handle is sleeved on the circumferential outer wall of the inner sleeve. A receiving groove is formed in the circumferential inner wall of the second connecting block near the first connecting block. A same tension spring is fixedly connected between one inner wall of the receiving groove and one side of the first connecting block. A same torsion spring is fixedly connected between the circumferential inner wall of the first connecting block and the circumferential inner wall of the handle. Limiting sliding grooves three and L-shaped limiting sliding grooves are respectively formed in the circumferential inner wall of the handle.

[0008] In a possible design, two symmetric limiting sliding blocks one are fixedly connected to the circumferential outer wall of the inner sleeve.
