Abstract
A head-mounted device includes a first housing, two second housings, a lacing assembly and a tightness adjustment mechanism. The lacing assembly comprises a first head band and a second head band, and one end of the first head band and one end of the second head band are overlapped and connected to form an overlapping portion. A ratchet pawl mechanism of the tightness adjustment mechanism has a ratchet pawl mechanism, and the tightness adjustment mechanism is matched with the overlapping portion through the ratchet pawl mechanism to adjust a length of the overlapping portion. The present disclosure provides a tightness adjustment mechanism, which can adjust the tightness of the first head band and the second head band by adjusting the length of the overlapping portion of the ratchet pawl mechanism.
