[0005] Preferably, the adjusting screw comprises a long screw that passes through the two mounting holes from bottom to top, an adjusting knob that is threadedly connected to the top of the long screw, and a locking screw that passes through the adjusting knob on the side surface to fix the adjusting knob and the long screw, the adjusting knob is located above the mounting block, and rotating the adjusting knob drives the long screw to rotate synchronously.

[0006] Preferably, the threaded hole of the adjusting block is an eccentric hole, one side of the adjusting block with a thick wall is close to the inner side surface of the mounting block and an installation groove is formed at this position, and the front end of the mirror foot is inserted into the installation groove to prevent the adjusting block from rotating.

[0007] Preferably, the mirror foot comprises a metal mirror foot insert on the inner side and a plastic mirror foot wrapped outside the mirror foot insert.

[0008] The utility model discloses simple structure novel, can adjust the body leg inclination angle of trial mirror frame through the rotation of adjusting screw, in order to be convenient for the face shape of different people, can avoid the bad effect of spectacles due to the deviation of body leg inclination angle, is favorable to the unification of optometry effect and spectacles effect.
