The glasses body is configured to be position limited at one of the at least one open position. ## Claims ### Claim 1 A head-mount device comprising: a headband body; a glasses body configured to rotate relative to the headband body among a plurality of positions including a use position and at least one open position, the glasses body being configured to be position limited at one of the at least one open position, and the glasses body including a mask configured to be fit to a user's face and a main portion configured to match the mask, the main portion being configured to rotate relative to the headband body while the mask remains stationary with respect to the headband body; and a rotating shaft mechanism rotatably coupling the glasses body to the headband body. ### Claim 2 (depends on 1) The head-mount device according to claim 1, wherein: the rotating shaft mechanism is coupled to the headband body and the glass body, and includes: a pressure assembly; and a connecting member including a connecting portion configured to rotate relative to the pressure assembly; and a damping force generated by a rotation of the connecting portion relative to the pressure assembly is greater than a gravity of the glasses body. ### Claim 3 (depends on 2) The head-mount device according to claim 2, wherein: the pressure assembly is mounted to the headband body; and the connecting member is mounted to the glasses body. ### Claim 4 (depends on 3) The head-mount device according to claim 3, wherein: the pressure assembly includes: a stationary seat mounted to the headband body and including a mounting shaft; an abutment member and a lock member arranged at the mounting shaft; and an elastic component arranged between the abutment member and the lock member, and the connecting member is fixed with respect to the pressure assembly under an abutment by the abutment member. ### Claim 5 (depends on 4) The head-mount device according to claim 4, wherein: the connecting member includes a mounting portion securely attached to the glasses body, the connecting portion being attached to the mounting portion; and the connecting portion is arranged at the mounting shaft and between the abutment member and the stationary seat, and is abutted by the abutment member. ### Claim 6 (depends on 5) The head-mount device according to claim 5, 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. ### Claim 7 (depends on 5) The head-mount device according to claim 5, 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. ### Claim 8 (depends on 7) The head-mount device according to claim 7, wherein: the inclined surface of the contact surface is configured to increase 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. ### Claim 9 (depends on 8) The head-mount device according to claim 8, 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. ### Claim 10 (depends on 2) The head-mount device according to claim 2, wherein: the rotating shaft mechanism includes a positioning pin in the headband body and an elastic member abutting against the positioning pin; and the connecting portion includes a positioning slot that matches the positioning pin. ### Claim 11 (depends on 10) The head-mount device according to claim 10, wherein: the connecting portion includes a cam plate; the positioning slot is arranged at a low point of the cam plate; when the glasses body is at the use position with respect to the headband body, the positioning pin is at a high or highest point of the cam plate; and when the glasses body is at the one of the at least one open position with respect to the headband body, the positioning pin matches the positioning slot. ### Claim 12 (depends on 1) The head-mount device according to claim 1, wherein: the rotating shaft mechanism is coupled to the headband body and the glasses body, and includes: a pressure assembly; and a connecting member including a connecting portion, the connecting portion including a flange plate and being configured to rotate relative to the pressure assembly; and a damping force generated by a rotation of the connecting portion relative to the pressure assembly is greater than a gravity of the glasses body. ### Claim 13 (depends on 12) The head-mount device according to claim 12, wherein: the pressure assembly is mounted to the headband body; and the connecting member is mounted to the glasses body. ### Claim 14 (depends on 13) The head-mount device according to claim 13, wherein: the pressure assembly includes: a stationary seat mounted to the headband body and including a mounting shaft; an abutment member and a lock member arranged at the mounting shaft; and an elastic member arranged between the abutment member and the lock member; and the connecting member is fixed with respect to the pressure assembly by an abutment of the abutment member. ### Claim 15 (depends on 14) The head-mount device according to claim 14, wherein: the connecting member includes a mounting portion securely attached to the glasses body, the connecting portion being attached to the mounting portion; and the connecting portion is arranged at the mounting shaft and between the abutment member and the stationary seat, and is abutted by the abutment member. ### Claim 16 (depends on 15) The head-mount device according to claim 15, wherein: a contact surface of the connecting portion and 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.
