Rotating shaft structure for virtual reality or augmented reality glasses, and glasses

A rotating shaft structure for virtual reality (VR) or augmented reality (AR) glasses, configured to be connected to a glass frame and a glass foot of the glasses, the rotating shaft structure comprising:

• a first housing, having a guide groove, wherein the guide groove comprises two retaining walls and a recess located between the retaining walls;
• a second housing, relatively rotatably fitted with the first housing, wherein at least part of the second housing is located within the first housing;
• an annular frame, rotatably arranged in the first housing and engaged with the second housing, wherein the annular frame has a positioning post extending toward the guide groove, the positioning post is arranged corresponding to the guide groove, and the positioning post is configured to abut against the guide groove and move relative to the guide groove;
• an elastic body, arranged in the first housing and the second housing, wherein two ends of the elastic body are respectively connected to the first housing and the annular frame;
• and
• a rotating shaft, extending through the first housing, the elastic body, and the annular frame, wherein
• when the first housing rotates relative to the second housing through the rotating shaft, the first housing further rotates relative to the annular frame, so that the positioning post moves relative to the guide groove and the positioning post selectively stops at the retaining walls or the recess.
