The screwless eyeglasses frame further includes two first connecting portions respectively disposed at two ends of the rim, and two second connecting portions individually disposed at one end of each of the temples. Each of the first connecting portions includes a first body, an accommodating slot, a pivotal rotation channel, a sliding channel, and a positioning groove. Each of the second connecting portions includes a second body, a protruding block, a pivotal rotation axis and a sliding block. The pivotal rotation axis is able to sequentially enter the sliding channel, the pivotal rotation channel and the positioning groove. When the pivotal rotation axis is abutted against a lower end of the positioning groove, the second connecting portion is able to pivotally rotate correspondingly to the first connecting portion.
1. A screwless eyeglasses frame, comprising a lens, a rim around an outer edge of the lens, and two temples respectively connected to two ends of the rim, two sides of the lens being defined as a front side and a back side, wherein the screwless eyeglasses frame further comprises:
