When the camera needs to be used, the driving piece drives the cylindrical cam 21 of the cam mechanism to rotate, and the cam pushes the driven rod 22 to axially move along the direction extending to the outer side of the shell 11, so that the camera fixedly arranged on the camera support 32 is pushed to extend to the outer side of the shell 11 through the shell through hole 12; when the camera is not used, the driving piece drives the cylindrical cam 21 of the cam mechanism to rotate, so that the driven rod 22 axially moves along the retracting direction towards the inner side of the shell 11, and the camera fixedly arranged on the camera support 32 is driven to retract towards the inner side of the shell 11 until the camera retracts into a cavity surrounded by the shell 11; the camera telescopic adjusting mechanism can adjust the camera to extend out of the shell 11 or retract back to the inner side of the shell 11 according to needs, and solves the problem that the camera is exposed on the outer side of the head-mounted equipment and is easy to damage.
In the present embodiment, the side surface stopper groove 25 includes an elevating groove portion 251 provided in an arc shape on the circumferential side surface of the columnar cam 21, a first flat groove portion 252 connected to an end portion of the elevating groove portion 251 on the side close to the camera and extending in the circumferential direction of the columnar cam 21; the corresponding end face limiting groove 26 is arranged on the end face of the cylindrical cam 21 close to the camera, and the end face limiting groove 26 comprises a first arc-shaped groove 261 corresponding to the lifting groove part 251 and a straight groove part 262 corresponding to the first flat groove part 252; a rotating shaft 31 is rotatably installed in the cavity defined by the housing 11, the camera support 32 can axially slide relative to the rotating shaft 31 and cannot circumferentially rotate, and a rotating shift lever 33 which is arranged at an interval with the rotating shaft 31 and is inserted into the end face limiting groove 26 is fixedly connected to the rotating shaft 31.
