Rimless glasses press-to-change lens structure

A rimless glasses press-to-change lens structure, comprising a lens, a temple, and a coupling device, wherein

• the lens has a coupling portion formed on an outer side thereof, wherein the coupling portion has a positioning hole arranged thereof, and a guide groove provided in the positioning hole and connected with the outside of the coupling part,
• wherein the temple has a pivot section arranged at a front end thereof,
• wherein the coupling device is arranged between the lens and the temple, wherein the coupling device has a receiving groove formed concavely on an inner side thereof, wherein the receiving groove includes a pivot unit provided therein that corresponding and matching with the pivot section of the temple, and an inserting slot connected to the outside of the coupling device at a front end of the receiving groove for the coupling portion of the lens to be plugged and coupled, wherein the coupling device has a pressing member arranged in the receiving groove, wherein the pressing member has a pivot portion arranged at a rear end thereof corresponding to the pivot unit, so that the pivot portion and the pivot section of the temple are pivotally combined with the pivot unit, and an outer edge of the pivot portion is supported against an inner end surface of the receiving groove, so that a pressing activity space is formed between the pressing member and the inner end surface of the receiving groove through the abutment support of the outer edge of the pivot portion, wherein the pressing member has a convex extension section protruding from an inner end face thereof corresponding to the guide groove of the lens, a latch part formed at an outer end of the convex extension section.
