A fixing block 11 is fixedly connected to one side of the first outer shell 1 at equal intervals, and a connecting seat 10 is fixedly connected to one side of the fixing block 11. The connecting seat 10 has a locking groove 23 inside that cooperates with the locking block 17. In use, the movement of the locking block 17 is limited by the storage slots 22, and the locking block 17 can lock the position of the connecting seat 10 by moving into the locking groove 23. This facilitates the fixation between the first outer shell 1 and the second outer shell 6 when the display screen is unfolded, enhancing the stability of the display screen when unfolded.

[0029] Furthermore, a sliding rod 21 is slidably connected inside the fixing plate 9, and a locking block 17 is fixedly connected to the sliding rod 21. A sliding block 19 is fixedly connected to one side of the sliding rod 21, and the sliding block 19 is slidably connected to the fixing plate 9. The sliding rod 21 is moved by the sliding block 19, and the sliding rod 21 moves the locking block 17, which facilitates the fixing between the first outer shell 1 and the second outer shell 6 when the display screen is unfolded.

[0030] Furthermore, a fixing seat 20 is fixedly connected at equal intervals on one side of the fixing plate 9, and a lead screw 18 is rotatably connected between the two fixing seats 20. The sliding block 19 is threadedly connected to the lead screw 18.
