Furthermore, in terms of the design details of the device, a ball 12 is set at the bottom of the turntable 21. This ingenious design plays an important role in the rotation of the turntable 21. The ball 12 can effectively assist the rotation of the turntable 21, reduce the friction between the turntable 21 and the bottom support surface, and make the rotation of the turntable 21 smoother and more stable. This smooth rotation not only improves the overall display stability of the device and avoids possible shaking or jamming during rotation, but also further improves the smoothness of adjusting the rotation, bringing users a more comfortable and convenient user experience, and fully demonstrating the scientific and human-centered design of the device.

[0031] By setting the adjustment mechanism 2, during use, when the second motor 29 is started, its power will drive the lead screw 24 inside the rail frame 23 to start rotating. Since the slider 25 and the lead screw 24 are connected by a thread, as the second motor 29 drives the lead screw 24 to rotate continuously, the lead screw 24 will drive the slider 25 to slide up and down inside the rail frame 23 according to the transmission principle of the thread. This up and down sliding action has an important adjustment function. The movement of the slider 25 can assist in pushing the hinge 26, thereby driving the linkage rod 27 to rotate. The hinge seat 28 on the linkage rod 27 is linked to the digital display screen 5 by a hinge, so that by precisely adjusting the up and down sliding position of the slider 25, the angle of the digital display screen 5 can be cleverly adjusted. This precise adjustment of the angle of the digital display screen 5 can... This device allows for flexible adjustment of the display angle of the digital display screen 5 according to the viewing needs of different audiences and the requirements of actual scenarios. This ensures that the audience can view the content from the best angle, greatly improving the viewing experience and information reception. Furthermore, this angle adjustment function works in conjunction with the rotation function of the turntable 21 to form a comprehensive, multi-angle display adjustment system. When the turntable 21 rotates the digital display screen 5, combined with the flexible changes in the angle of the digital display screen 5 itself, the form and effect of the display can be further enriched, and information can be displayed from all angles. This further improves the overall display effect of the device, highlighting its advanced and innovative design in display functions, making it stand out among many display devices and meeting the needs of various complex display scenarios.
