After the host 51 and the binding band adjusting device are pulled, the head-mounted display product can be worn on the head of a user after the host 51 slides in the deviating direction with the left support arm 12a and the right support arm 12b; because the head-mounted display product of the invention is tightness-adjusted by the left elastic compression piece 41a and the right elastic compression piece 41b and the left connecting rope 45a and the right connecting rope 45b, the left connecting rope 45a and the right connecting rope 45b do not influence the arrangement of the left support arm 12a and the right support arm 12b, and the arrangement direction can be conveniently adjusted according to the requirement, thereby solving the problem that the support arm of the prior product can only be made into a straight direction.
Specifically, the two mounting plates 52 are respectively inserted into the corresponding left and right support arms 12a and 12b to realize sliding connection, so that the left and right connection ropes 45a and 45b are not leaked, damage to the left and right connection ropes 45a and 45b can be prevented, and the device is more attractive.
Since the main body portion of the strap adjustment device is disposed at the rear of the user's head when wearing the head-mounted display product, connected with the main body 51 for fixing the main body 51 to the user's face, the entire strap adjustment device is also called rear head-mounted.
The foregoing description of the embodiments of the invention is not intended to limit the invention to the particular embodiments disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.
