In some examples, both support bars 410 are inverted L-shaped.

In particular, reference is made to fig. 1 and 2. The two support bars 410 on the first casing 310 have an inverted L shape, that is, one portion of the support bars 410 extends in the Z-axis direction and the other portion extends in the X-axis direction. It is understood that the left and right support rods 410 having the inverted L shape are symmetrically disposed, and the portions of the two support rods 410 extending in the X-axis direction are disposed opposite to each other. Thus, when the first sliding assembly 710 is provided, the upper end of the screw 711 may be rotatably coupled to any one of the portions of the inverted-L support bar 410 extending in the X-axis direction; when the second sliding assembly 720 is provided, the upper end of the vertical rod 721 may be fixedly connected to any one of the portions of the inverted-L support rod 410 extending in the X-axis direction.

In a specific example, the display device further includes a pulley block 90, where the pulley block 90 includes at least four pulleys 910, and each pulley 910 is symmetrically disposed at the bottom of the first case 310.

Specifically, the display device is first placed in a designated position when in use. Therefore, by providing the pulley block 90, and the pulley block includes at least four pulleys 910, each pulley 910 is symmetrically disposed at the bottom of the first housing 310, so that only a pushing force needs to be applied to the display device, and each pulley 910 can roll correspondingly to facilitate the movement operation of the display device. Illustratively, the pulley assembly 90 includes four pulleys 910, the pulleys 910 being universal wheels with a locking mechanism. The stability and the flexibility of the display device in the moving process are guaranteed, and the display device can be fixed through the locking mechanism after moving to the designated position, so that the subsequent use and display are convenient.
