[0034] Furthermore, the rotating disk 5 includes a plurality of extension portions 13 extending outward, and each extension portion 13 is provided with the rotating lock 7 and the eccentric rotating member 9 respectively.

[0035] As can be seen from the above description, there are multiple eccentric rotating parts 9, so that the display screen can be slightly displaced in multiple directions in the vertical plane, thereby improving the fine-tuning accuracy, thereby better eliminating the seam between two adjacent display screens, and further improving the display effect of the display device. In order to reduce the volume, preferably, the extension part has an inclined angle, and the extension parts are all inclined in the same direction.

[0036] Furthermore, the eccentric rotating member 9 includes a cylinder 14 , and an adjustment column 15 is eccentrically provided on one end surface of the cylinder 14 , and the adjustment column 15 is exposed on the turntable 5 .

[0037] It can be seen from the above description that the eccentric rotating member 9 has a simple structure, is easy to process, and has a low manufacturing cost, which is beneficial to controlling the production cost of the connecting lock 3.
