[0044] Preferably, the button 51 is installed on the front outer side of the upper strip portion 2, and the connecting rod 52 is suspended above the guide rail 41, and the limit block 56 and the fixed block 57 are both located at the rear side of the sliding cavity 21, and only the protrusion 571 at the bottom end of the fixed block 57 extends downward to engage with the sliding limit groove 34, so that it will not be exposed, and thus will not interfere with the two display screens 3 flipping forward and stacking together, and the limit block 56 is fixed on the rear side wall of the sliding cavity 21, and the U-shaped guide groove 561 is slidably sleeved on the slider 53, which can play a role in horizontally limiting the slider 53 in the length direction of the strip portion 2, and prevent the protrusion 571 at the bottom of the fixed block 57 from being misaligned with the limit groove 34;

[0045] Specifically, when the two display screens 3 that are flipped into a plane need to be pushed horizontally, the button 51 is pressed to push the slider 53 toward the limit block 56 through the connecting rod 52. At this time, the spring member 54 in the guide slot hole 531 will be compressed, and the guide rod 55 can play a guiding and supporting role for the sliding slider 53. Then, the sliding of the slider 53 will drive the protrusion 571 at the bottom end of the fixed block 57 to disengage from the limit slot 34 provided on the back side of the frame of the display screen 3, and the guide rod 58 can play a role in sliding the fixed block 57 in the width direction of the cavity 21. The horizontal guiding effect of the display screen 3 can be realized by the operator, so that the operator can push the unfolded display screen 3, and then the slide block 42 can slide on the guide rail 41 through the driving of the connecting block 43, so that the unfolded display screen 3 can slide to the left, center or right position on the back panel 1 at will, thereby improving the convenience and comfort of the operator in viewing the display screen 3. When the display screen 3 slides to a suitable position, the operator releases the button 51, so that the elastic restoring force of the spring member 54 drives the slider 53 and the connecting rod 52 to slide in the direction away from the limit block 56, and then the display screen 3 is unfolded. The fixed block 57 will drive the raised portion 571 at the bottom to slide and snap into the limit groove 34, so as to lock and fix the display screen 3 after the sliding adjustment, so that the display screen 3 will not slide freely due to accidental contact. In the present invention, the connecting rod 52 is suspended above the guide rail 41, so that it will not interfere with the normal sliding of the slide rail block 42, and at the same time, it can push the slider 53 and the fixed block 57 to slide and move. The fixed block 57 and the limit block 56 are both located on the outer side of the connecting block 43, so that it will not interfere with the normal sliding of the unfolded display screen 3 driven by the connecting block 43, and The limit block 56 can also guide and limit the fixed block 57.

[0050] In the embodiment of the present invention, the disengagement clamping assembly 6 includes a connecting strip 61, a push rod 62, a U-shaped strip 63 and a sliding frame 64. The top end of the sleeve 31 and the rotating shaft 32 located at the top extend upward into the sliding cavity 21, and are located at the other side of the connecting block 43. The sliding cavity 21 is provided with a connecting strip 61, and the connecting strip 61 is located below the slide rail block 42. The inner side surface of the end of the connecting strip 61 is fixed with a push rod 62. The rod 62 is aligned with the through hole 35 opened on the sliding sleeve 31, and the outer side surface of the connecting strip 61 is connected to the cavity wall of the sliding cavity 21 through the cooperation of the guide rod 55 and the spring member 54. The upper surface of the connecting strip 61 is connected to the lower horizontal strip of the U-shaped strip 63, and the U-shaped mouth of the U-shaped strip 63 corresponds to the slide rail block 42. The upper horizontal strip end of the U-shaped strip 63 is fixedly provided with a sliding frame 64, and the sliding frame 64 is sleeved on the connecting rod 52;

[0051] Specifically, when it is necessary to rotate the stacked display screens 3 to unfold, the button 51 is pressed first to push the sliding frame 64 in contact with the side to slide in the direction of the limit block 56, and then the sliding frame 64 will drive the connecting strip 61 connected at the bottom to slide in the direction away from the cavity wall of the sliding cavity 21 through the U-shaped strip 63, and then the connecting strip 61 will push the push rod 62 to insert into the through hole 35, so as to push the engaging ball 65 into the radial hole 33, thereby facilitating the opening of the stacked display screens 3. When the button 51 is released, the restoring force of the spring member 54 connected to the connecting strip 61 will drive the connecting strip 61 toward the sliding cavity 21. 1, and the push rod 62 will be disengaged from the through hole 35, and the U-shaped bar 63 will drive the sliding frame 64 to slide to the initial position, so as to facilitate the push rod 62 to be pushed and inserted again; and when the button 51 is pressed, so that the slider 53 and the protrusion 571 at the bottom of the fixed block 57 are disengaged from the limiting groove 34 through the connecting rod 52, the sliding frame 64 of the sliding sleeve will not interfere with the normal sliding of the connecting rod 52, and will not interfere with the normal sliding engagement or disengagement of the protrusion 571 and the limiting groove 34, and the U-shaped mouth of the U-shaped bar 63 corresponds to the slide rail block 42, so that it will not interfere with the sliding slide rail block 42.
