[0008] As a further step, the elastic extension arm is L-shaped.

[0009] The beneficial effects of this utility model are as follows: (1) The elastic hinge can form a snap-fit ​​between the frame and the temple during the installation process, so as to make a stable connection and ensure stability during use. It can avoid the trouble of screw installation during installation. (2) The limiting block on the left end of the elastic base plate is embedded in the groove at the rear end of the frame to prevent the frame from falling off. The structure is simple, ingeniously designed and has low manufacturing cost. (3) The end of the elastic extension arm is provided with a shaft connection part, the shaft connection part is provided with an open concave shaft position, the open concave shaft position of the shaft connection part is embedded in the open rotating shaft at the front end of the frame, and the frame and the elastic extension arm are movably connected, which solves the problem of avoiding the trouble of screw installation during installation.
