The preset adjustable angle is the adjustable angle of the first included angle between the head-mounted shell 110 and the first support arm 210. In this way, the maximum value of the angle of the first included angle between the head-mounted shell 110 and the first support arm 210 can be limited, so as to prevent the adjustment range of the first included angle from being too large, which causes excessive pulling of the cable 400 and unstable signal transmission.

[0069] Specifically, the wire locking piece 300 can be provided with a plurality of wire bundling holes, and the cable 400 passes through the wire bundling holes and is fixed by the wire locking piece 300, so as to prevent the cable 400 from bearing tension or pressure during the height and pitch angle adjustment of the VR display device, thereby ensuring the stability of data transmission.

[0070] The first wire slot 230 can be formed with a third wire slot 235, and the cable 400 passing through the first wire slot enters the third wire slot 235 and is locked by the wire locking piece 300, and then is connected to the head-mounted display housing 110.

During the change of the second included angle between the head-mounted display housing 110 and the third support arm, the first support arm 210 drives the second rotating shaft assembly 240 to rotate. The third connector 243 and the fourth connector 244 slide along the cylindrical curved surfaces of the two third through holes 2112, respectively, realizing the relative rotation of the first support arm 210 and the second support arm 220. The third fixing member 241, the fourth fixing member 242, the third connector 243, and the fourth connector 244 provide locking force for the connection between the head-mounted display housing 110 and the third support arm, and realize the damping effect of the second rotating shaft, thus realizing the hovering of the VR optical engine display device 10.
