[0014] The beneficial effect of adopting the above further scheme is that the two plastic U-shaped blocks can cover the upper and lower sides of the spectacle frame.

[0015] Furthermore, torsion springs are fixed to the left and right ends of the two rotating rods.

[0016] The beneficial effect of adopting the above further scheme is that the torsion springs can reset the two flipping plates.

[0017] Furthermore, the left and right torsion springs are respectively fixed at the rotational connection between the left and right rotating rods and the placement groove.

[0018] The beneficial effect of adopting the above further scheme is to reset the two flipping plates.

[0019] Furthermore, two receiving grooves located on the hanging rack are formed in the front wall of the inner cavity of the placement groove.
