         5 . The head-mount device according to  claim 1 , wherein:
 under an abutment by the abutment member, the connecting member is configured to be stationary with respect to the pressure assembly when no external force is applied to the glasses body.   
     
     
         6 . The head-mount device according to  claim 1 , wherein the connecting member includes:
 a mounting portion configured to be securely attached to the glasses body; and   a connecting portion attached to the mounting portion, arranged at the mounting shaft and between the abutment member and the stationary seat, being abutted by the abutment member, and being configured to rotate relative to the pressure assembly.   
     
     
         7 . The head-mount device according to  claim 6 , wherein the connecting portion includes a flange plate. 
     
     
         8 . The head-mount device according to  claim 6 , wherein:
 a contact surface of the connecting portion for contacting the abutment member includes a plane; and   the pressure assembly is configured to apply an elastic force to the contact surface of the connecting portion, to cause the connecting member to be fixed with respect to the pressure assembly when the connecting member is not being operated.   
     
     
         9 . The head-mount device according to  claim 6 , wherein:
 a contact surface of the connecting portion for contacting the abutment member includes an inclined surface; and   the abutment member is configured to interact with the inclined surface when the connecting member rotates relative to the pressure assembly, to change a damping force applied by the abutment member to the connecting portion.   
     
     
         10 . The head-mount device according to  claim 9 , wherein:
 the inclined surface of the contact surface is configured to rotate, when the glasses body rotates relative to the headband body from the use position to the one of the at least one open position, to decrease the damping force applied by the abutment member to the connecting portion.   
     
     
         11 . The head-mount device according to  claim 10 , wherein:
 the abutment member includes a positioning boss;   the contact surface includes a positioning groove; and   the positioning boss is configured to match the positioning groove, when the glasses body rotates relative to the headband body to the one of the at least one open position, to cause the glasses body to be fixed at the one of the at least one open position.   
     
     
         12 . The head-mount device according to  claim 1 , wherein:
