[0084] An interlocking bolt 1004 is rotatably connected to the top of the pushing shaft 1003, is screwed with the base 3, and is used to drive the pushing shaft 1003 to move.

[0085] Specifically, during the process of tightening the interlocking bolt 1004, the pushing shaft 1003 is driven to move downward, the traction cable 1002 is pressed into the buffer groove one 14 through the pushing shaft 1003, and then the linkage disc 1008 is driven to slide upward through the traction cable 1002, so as to drive the linkage disc 1008 to expand through the interlocking bolt 1004.

[0086] Please refer to Figure 5 、 Figure 6 、 Figure 11 and Figure 12 , a buffer groove two 15 is arranged inside the base 3 and below the adjusting groove 12, a shaft groove 16 is arranged in the middle of the bottom of the buffer groove two 15, and the linkage mechanism 10 further comprises a reset rod 1005 fixed to the outer ring of the traction cable 1002 near the bottom and in the middle, which is used to press the traction cable 1002 into the buffer groove two 15;

After losing the support of friction force, the sector gear 904 no longer limits the rotation of the main support 5, at this time, the main support 5 can rotate independently to adjust the position of the clamping roller 806, so as to clamp irregular smart display screens, such as wave-shaped ribbon screens, and improve the adaptability of the support assembly.

[0090] Working principle

[0091] When clamping and fixing the intelligent display screen, first loosen the second plum blossom bolt 805, slide the clamping roller 806 along the radial direction of the roller sleeve 803, adjust the position of the clamping roller 806, so that the clamping roller 806 can adapt to intelligent display screens of different thicknesses, then tighten the second plum blossom bolt 805 to fix the clamping roller 806, then pull the sub-bracket 801 to make it slide in the sliding groove 6, adjust the overall length of the bracket body according to the height of the intelligent display screen, and then adjust the position of the clamping roller 806, so that the clamping surface of the clamping roller 806 is perpendicular to the outer wall of the intelligent display screen, the anti-slip sleeve 807 increases the contact friction force, and the stability of the intelligent display screen clamped and fixed by the bracket assembly is improved. When the pre-clamping spring 802 is contracted and tightened, the anti-slip sleeve 807 outside the clamping roller 806 tightly abuts against the outer wall of the intelligent display screen, the intelligent display screen is clamped, and then the first plum blossom bolt 7 is tightened to compress the sub-bracket 801, thereby improving the stability after clamping and fixing;

[0092] When the angles of the four main brackets 5 need to be adjusted synchronously, the interlocking bolt 1004 is first tightened. During the tightening of the interlocking bolt 1004, the push shaft 1003 is driven to move downward, the traction steel cord 1002 is pressed into the buffer groove 14 through the push shaft 1003, the linkage disc 1008 is then driven to slide upward through the traction steel cord 1002, the connecting rod 1009 is then driven to rotate, the friction locking block 1010 is lifted by the connecting rod 1009, a plurality of friction locking blocks 1010 are simultaneously expanded outward, the wear-resistant anti-slip pattern 905 is compressed and tightened by the friction locking block 1010 to increase the friction, the locking sector gear 904 is locked, and the main bracket 5 is locked. At this time, rotating the trapezoidal screw 901 drives the trapezoidal nut 902 to slide inside the adjusting groove 12. Since the sector gear 904 is meshed and connected with the tooth groove 903, when the trapezoidal nut 902 moves, the sector gear 904 is driven to rotate, and then the main bracket 5 connected with the sector gear 904 is synchronously rotated, thereby facilitating synchronous adjustment of the angle of the main bracket 5.

[0093] When the clamped intelligent display screen is a flat display screen, the main bracket 5 is perpendicular to the base 3, and the roller sleeve 803 and the sub-bracket 801 are on the same straight line. When the clamped intelligent display screen is a curved display screen, the main bracket 5 is adjusted according to the bending degree of the curved display screen, and then the angle of the sub-bracket 801 is adjusted, the clamping roller 806 is driven to approach the outer wall of the curved display screen, the roller sleeve 803 is then rotated to adjust the angle of the clamping roller 806, so that the clamping surface of the clamping roller 806 is perpendicular to the outer wall of the curved display screen. After adjustment, the cam lock catch 804 is pulled to lock the roller sleeve 803, and then the sub-bracket 801 is pulled to adjust the overall length of the bracket body, so that the anti-slip sleeve 807 outside the clamping roller 806 abuts against the outer wall of the curved display screen, and then the curved display screen is clamped.

[0094] When clamping an irregular smart display screen, such as a wave-shaped ribbon screen, the positions of the four clamping rollers 806 need to be adjusted independently, at this time, the interlocking bolt 1004 is loosened, in the process of loosening the interlocking bolt 1004, the reset spring 1007 drives the push reset rod 1005 to move, the traction steel wire 1002 is pressed into the buffer groove two 15, and then the traction steel wire 1002 drives the linkage disc 1008 to slide downward, cooperates with the connecting rod 1009 to drive the friction locking block 1010 to fold, so that the friction locking block 1010 is separated from the wear-resistant anti-skid pattern 905, after losing the support of friction, the sector gear 904 no longer limits the rotation of the main support 5, at this time, the main support 5 can rotate independently, by rotating each main support 5 independently, the position of each clamping roller 806 is adjusted independently to clamp and fix the outer wall of the ribbon screen, after adjustment, the interlocking bolt 1004 is tightened to lock the main support 5, avoiding the rotation of the main support 5, and facilitating independent adjustment of the clamping roller 806 according to the demand to clamp and fix the irregular smart display screen.
