[0034] Working principle: the embodiment provides a telescopic glasses leg glasses, which is used when:

[0035] When the length of the glasses leg needs to be adjusted, the user applies an external force to the mirror leg main body 201 and the anti -drop rubber tail hook 202. Because the guide keys 211 on both sides in the anti -drop rubber tail hook 202 are matched with the guide grooves 212 on both sides of the outer edge surface of the mirror leg main body 201, this provides a stable guiding effect for the telescopic process, enabling the anti -drop rubber tail hook 202 to smoothly slide along the mirror leg main body 201. During the sliding process, the wave bead screw 209 will move between the positioning grooves 210 on the mirror leg main body 201 as the position changes. When the wave bead screw 209 is clamped into the appropriate positioning groove 210, a certain resistance is generated, thereby fixing the mirror leg main body 201 and the anti -drop rubber tail hook 202 at the current position, realizing accurate adjustment of the length of the glasses leg to adapt to the needs of different user head sizes and face shapes.

[0036] Anti -drop principle of downward inclination: during the wearing of glasses, when the user bends down, the head posture changes, and the glasses are prone to slide down due to gravity. At this time, the downward inclination limiting hook 204 on the rubber sleeve A 203 at one end of the anti -drop rubber tail hook 202 plays a role. The unique shape of the rubber downward inclination limiting hook 204 is matched with the shape of the root of the user's ear. When the glasses have a tendency to slide down, the rubber downward inclination limiting hook 204 will closely fit the root of the ear, effectively preventing the glasses from continuing to slide down by utilizing the friction force and close fitting fixation between the two, ensuring that the glasses can still be stably worn when bending down.

[0037] The anti-upward-sliding principle: when the user looks up, the glasses may slide upward due to the head movement. At this time, the anti-upward-sliding component works. The rubber anti-upward-sliding limiting hook 206 at the bottom end of the rubber sleeve B 205 on one end of the anti-removal rubber tail hook 202 is matched with the shape of the upper ear root. When the glasses have a tendency to slide upward, the rubber anti-upward-sliding limiting hook 206 tightly abuts against the upper ear root, and the fixed effect is generated by the friction and adhesion between the two, so as to prevent the glasses from moving upward and ensure that the glasses can be stably worn when the head is raised.
