the first limiting plate is provided with a first guide rail parallel to the first slide rail, and one end of the first rotating shaft penetrates through the first slide rail to be in sliding fit with the first guide rail;

the first limiting hole is used for being clamped with the first rotating shaft when the first rotating shaft slides to the tail end of the first sliding rail so as to limit the relative rotation of the first rotating shaft and the first shell.

4. The display assembly of claim 3, wherein the first spacing mechanism further comprises a spacing block fixedly connected to the first spacing plate, the first spacing hole being disposed on the spacing block; the limiting block is provided with an opening connected with the first guide rail, the end face of the opening is a slope, and the opening is inclined from one side close to the first guide rail to the center of the first limiting hole.

5. The display assembly of claim 4, wherein the first shaft includes a first shaft body rotatably coupled to the first hinge mechanism and a second shaft body disposed at one end of the first shaft body, the first shaft body having a circular cross-sectional shape;

the section of the second shaft body is hexagonal, and the second shaft body comprises two sliding surfaces which are arranged in parallel and are used for being in sliding fit with the first guide rail; the second shaft body is also used for being clamped with the first limiting hole, and the cross section shape of the first limiting hole is matched with the cross section shape of the second shaft body.

6. The display assembly of claim 5, wherein the first slide rail comprises a first rail and a second rail disposed on opposite sides of the hinge sleeve, the first rail and the second rail being slidably engaged with the first shaft, respectively;

the first sliding mechanism further comprises two stop blocks sleeved on the first shaft body, the stop blocks are respectively in sliding fit with the first rail and the second rail, the stop blocks comprise stop surfaces which are in contact with the upper surface of the first sliding rail, and the stop surfaces are used for limiting the second housing to move in the direction perpendicular to the first sliding rail.

7. The display assembly of claim 1, further comprising:

the electric connection mechanism comprises a first connection end arranged on the first shell and a second connection end arranged on the second shell, and is used for enabling the first connection end to be in contact with the second connection end to realize electric connection of the second display panel when the first rotating shaft slides to the tail end of the first sliding rail;

the second sliding mechanism comprises a second sliding rail arranged on the first shell and a sliding block arranged on the second connecting end, and the second sliding rail is in sliding fit with the sliding block so as to realize sliding fit between the second connecting end and the first shell.

8. The display assembly of claim 7, further comprising:

the second hinge mechanism is arranged on the second shell and comprises a second connecting block fixedly connected with the second shell and a second rotating shaft rotatably connected with the second connecting end;

the second limiting mechanism is arranged on the first shell and comprises a second limiting plate and a second limiting hole arranged on the second limiting plate, wherein,

the second limiting plate is provided with a second guide rail parallel to the second slide rail, and one end of the second rotating shaft penetrates through the second slide rail to be in sliding fit with the second guide rail;

the second limiting hole is used for being clamped with the second rotating shaft when the second rotating shaft slides to the tail end of the second sliding rail, so that the second rotating shaft is limited to rotate relative to the second shell.

9. The display assembly of claim 7, wherein an outer clamping portion is provided on the first connection end, an inner clamping portion is provided on the outer clamping portion, and a first connection terminal is provided on the inner clamping portion; an outer clamping part matched with the outer clamping part is arranged on the second connecting end, an inner clamping part matched with the inner clamping part is arranged on the outer clamping part, and a second connecting terminal is arranged on the inner clamping part;

the second wiring terminal is electrically connected with the second display panel through a flexible flat cable.

10. A display device comprising a display assembly as claimed in any one of claims 1 to 9.
