The display module comprises a first display part 105 and a second display part 106, the first display part 105 is installed on the first sliding plate 2 and moves with the first sliding plate 2, and the second display part 106 is installed on the second sliding plate 3 and moves with the second sliding plate 3. Therefore, the distance between the first display part 105 and the second display part 106 can be adjusted by the eye relief adjustment device 100. Moreover, the limiting spring piece 5 is installed on the inner side wall of the shell 102, the surface of the limiting spring piece 5 protrudes to form a limiting block 54 towards the first sliding plate 2, the surface of the first sliding plate 2 is recessed to form a plurality of limiting grooves 234 facing the limiting spring piece 5, a plurality of the limiting grooves 234 correspond to the limiting block 54, and the limiting block 54 is arranged to be clamped in one of the limiting grooves 234, thereby limiting the movement of the first sliding plate 2 and the second sliding plate 3, and improving the stability when wearing the head-mounted display 10.

[0030] Please refer to Figure 2 , Figure 3 and Figure 5The top surface of the shell 102 is provided with an adjusting slot 1021, and the top of the first sliding plate 2 is provided with an adjusting lever 23 which extends through the adjusting slot 1021 and is exposed on the top surface of the shell 102 so that the user can displace the first sliding plate 2 relative to the second sliding plate 3 by pulling the adjusting lever 23. The adjusting lever 23 comprises an extension plate 231 and a pulling portion 232. The top of the first sliding plate 2 extends towards the adjusting slot 1021 to form the extension plate 231, and the top end of the extension plate 231 extends outwardly to form the pulling portion 232. The width of the pulling portion 232 is greater than the width of the adjusting slot 1021 and is arranged outside the adjusting slot 1021 so as to be pulled by the user.

[0031] Please refer to Figures 4 to 7, in order to avoid the displacement of the first sliding plate 2 and the second sliding plate 3 which are in the adjusted position, the adjusting lever 23 is provided with a limiting part 233 and a plurality of limiting grooves 234, the limiting part 233 is shaped by the surface of the extension plate 231 and faces the limiting elastic sheet 5, the surface of the limiting part 233 is recessed inward to form a plurality of limiting grooves 234 which are side by side. The inner side wall of the shell 102 extends inward to form a pair of fixed parts 1022, the fixed parts 1022 are shaped as columnar structures and are combined with the two sides of the limiting elastic sheet 5, so that the limiting elastic sheet 5 is aligned with the limiting part 233. In a preferred embodiment of the drawings, the shell 102 is provided with a convex rib 1023, the convex rib 1023 is shaped by the inner side wall of the shell 102 and extends inward, the fixed parts 1022 are arranged on the two sides of the convex rib 1023 and are shaped by the surface of the convex rib 1023. The limiting elastic sheet 5 comprises an elastic cantilever 51, a pair of fixed feet 52, a pair of fixed holes 53 and the limiting block 54, the left and right ends of the elastic cantilever 51 are bent vertically and then extend outward to form the fixed feet 52, the fixed holes 53 pass through the fixed feet 52, the fixed parts 1022 pass through the fixed holes 53, and the fixed feet 52 are combined with the fixed parts 1022 by means of hot melting, so that the elastic cantilever 51 is suspended relative to the shell 102. The outer surface of the elastic cantilever 51 is protruded outward at the center to form the limiting block 54, the limiting block 54 is arranged to be clamped in one of the limiting grooves 234. During the displacement of the first sliding plate 2 by the adjusting lever 23, the limiting part 233 pushes the limiting block 54 laterally, at this time the elastic cantilever 51 is elastically deformed towards the inner side wall of the shell 102, so that the limiting part 233 passes through the limiting block 54 without being affected by the sliding interference. After the user stops applying force to the adjusting lever 23, the limiting block 54 rebounds and resets towards the limiting part 233 and is clamped in one of the limiting grooves 234, thereby realizing the positioning and holding of the first sliding plate 2 and the second sliding plate 3.

[0032] Please refer to Figure 3 and Figure 8The first sliding plate 2 comprises a first adjusting strip 21, which is formed by extending the inner side wall of the first sliding plate 2 towards the second sliding plate 3, and the first rack 22 is formed by protruding from the single side edge of the first adjusting strip 21. The second sliding plate 3 comprises a second adjusting strip 31, which is formed by extending the inner side wall of the second sliding plate 3 towards the first sliding plate 2, and the second rack 32 is formed by protruding from the single side edge of the second adjusting strip 31.

[0033] Please refer to Figures 2 to 4 When the user pushes the knob 232, the displacement of the first rack 22 causes the adjusting gear 4 to rotate, and the relative displacement of the second rack 32 is caused at the same time, so as to adjust the distance between the first display part 105 and the second display part 106 arranged on the first sliding plate 2 and the second sliding plate 3. Further, when the user pushes the knob 232 towards the outside, the first sliding plate 2 slides outwardly, and the first rack 22 is displaced towards the second sliding plate 3, and the adjusting gear 4 is rotated counterclockwise at the same time, and the second rack 32 is displaced towards the first sliding plate 2 with the rotation of the adjusting gear 4, so as to increase the distance between the first display part 105 and the second display part 106. Conversely, when the user pushes the knob 232 towards the inside, the first sliding plate 2 slides inwardly, and the first rack 22 is displaced towards the second sliding plate 3, and the adjusting gear 4 is rotated clockwise at the same time, and the second rack 32 is displaced towards the first sliding plate 2 with the rotation of the adjusting gear 4, so as to shorten the distance between the first display part 105 and the second display part 106. After the distance between the first sliding plate 2 and the second sliding plate 3 is adjusted, the displacement of the first sliding plate 2 and the second sliding plate 3 can be effectively avoided by limiting the position of the limiting block 54 and the limiting slot 234.
