Detailed Description

The embodiment of the inward bending mechanism for the connecting portion of the temple according to the present invention will be described in further detail with reference to fig. 1 to 3.

A connecting part inward bending mechanism for a glasses leg comprises a base 1, a supporting seat 2 arranged on a first rail 10 of the base 1, and a first driver for pushing the supporting seat 2 to be close to or far away from the glasses leg along the first rail 10;

the supporting seat 2 is provided with a bending seat 3 with a bending rack 5, a bending motor 4 and a large gear 6 meshed with the bending rack 5, and an output shaft of the bending motor 4 is provided with a small gear 7 meshed with the large gear 6;

the bending seat 3 is provided with an inward bending wheel 8 and a second driver 9 for driving the inward bending wheel 8 to be close to or far away from the earpiece;
