Head-mounted display device and binding band adjusting device thereof

Abstract

A binding band adjusting device and a head-mounted display device having the binding band adjusting device are provided. The binding band adjusting device includes a support assembly provided with a through hole, a rotating assembly matching the through hole, two side binding bands connected to the rotating assembly, a trigger assembly disposed on the support assembly and used for being triggered by the rotating assembly, and a front-back binding band that can fix with respect to the trigger assembly; when the rotating assembly rotates in different directions with respect to the through hole, the two side binding bands expand and contract with respect to the support assembly; when the rotating assembly moves in the axial direction of the through hole and triggers the trigger assembly, the trigger assembly loosens or clamps the front-back binding band.
