The main telescopic frame is hinged to one side of the base, and the other end is connected to one end of the hinge member. The tension member is disposed on the main telescopic frame and is used to drive the main telescopic frame to extend and retract between a first position and a second position. The first position is the position when the main telescopic frame is retracted to its limit safe travel, and the second position is the position when the main telescopic frame is extended to its limit safe travel.

6. The universal mounting bracket for hanging large liquid crystal display screens according to claim 5, characterized in that Two main telescopic frames are symmetrically arranged, and each main telescopic frame includes a main rod and a secondary rod. One end of the main rod is hinged to the base, and the other end is hinged to the secondary rod. The other end of the secondary rod is hinged to the hinge member. The tension member is arranged on the two main rods and connected to the secondary rod.

7. The large LCD screen wall-mounted universal adjustment bracket as described in claim 6, characterized in that, The tensioning component includes a driving gear, a driven gear, a threaded rod, and a tensioner. The driving gear is rotatably connected to the main rod, and the driven gear is disposed at one end of the threaded rod, with the driving gear engaging with the driven gear. Two tensioners are provided, each disposed on one of the two driven rods. Each tensioner has a threaded hole, and the threaded rod passes through both threaded holes, allowing the two tensioners to move on the threaded rods by rotation.

8. The universal mounting bracket for hanging large liquid crystal display screens according to claim 1, characterized in that, The connecting assembly includes a limiting member, an adapter, a display screen connector, an adapter post, and two steering arms. One end of each steering arm is detachably mounted on both ends of the adapter post, and the other end is connected to both ends of the adapter post.
