[0018] like Figure 1~Figure 3 As shown, a positioning fixture includes a transverse plate 1, a pair of guide transverse holes 10 are opened at both ends of the transverse plate 1, connecting rods are passed through the guide transverse holes 10, a movable outer plate 24 is provided at one end of the connecting rod at the same end, and a side plate 2 is provided at the other end of the connecting rod at the same end.

[0019] The other end of the side plate 2 is provided with a front baffle 20, on which an inner top screw 21 is screwed, and an inner top plate 22 is rotatably provided on the inner side end of the inner top screw 21. A rotating shaft 3 is provided at each end of the transverse plate 1, on which an eccentric disk 30 is eccentrically provided, and the outer periphery of the eccentric disk 30 is tangent to the outer wall of the movable outer plate 24. A V-shaped spring piece 25 is in contact with the other side of the movable outer plate 24, and the other end of the V-shaped spring piece 25 is mounted on the transverse plate 1 through a mounting plate 26. A swing arm 31 is provided on the outer periphery of the eccentric disk 30, and a swing long hole 32 is opened on the swing arm 31, and a moving pull rod 33 is inserted into the swing long hole 32, and a concave pull plate 34 is provided on the outer side end of the moving pull rod 33. A positioning screw 35 is screwed on the transverse section of the concave pull plate 34, and the upper end of the positioning screw 35 is rotatably provided on the transverse plate 1.

[0020] A rotating tube 4 is rotatably provided on the transverse plate 1, a suction cup 43 is provided at the inner end of the rotating tube 4, a piston is movably provided in the rotating tube 4, an end plate 40 is provided at the outer end of the rotating tube 4, a pull rod 41 is passed through the end plate 40, a pull cap 42 is provided on the pull rod 41, and a piston is provided at the inner end of the pull rod 41. A swing plate 5 is installed on the rotating tube 4, an adjustment long hole 50 is provided on the swing plate 5, a moving rod is passed through the adjustment long hole 50, a moving seat 51 is provided at the outer end of the moving rod, and a pair of limit screws 55 are provided at the outer end of the moving seat 51. A concave plate 53 is installed on the transverse plate 1, a pair of vertical guide holes 54 are provided on the vertical section of the concave plate 53, and the limit screws 55 pass through the vertical guide holes 54. A vertical screw rod 52 is rotatably provided on the concave plate 53, and the vertical screw rod 52 is screwed on the moving seat 51.

[0021] When operating this embodiment, the operator first presses the suction cup 43 against the back side of the LCD screen, and then pulls the pull rod 41 outward through the pull cap 42. When the pull rod 41 is pulled, the suction cup 43 fixes the LCD screen.

[0022] The operator then moves the LCD screen to the main installation location of the billboard.

[0023] Then, the positioning screw 35 is rotated to make the concave pull plate 34 move downward. When the concave pull plate 34 moves downward, the swing arm 31 will be pulled downward by the movable pull rod 33, and the eccentric disk 30 will rotate with the rotation of the swing arm 31. When the eccentric disk 30 rotates, it will act on the movable outer panel 24, and the movable outer panel 24 will drive the side panel 2 to move inward and make it close to the side wall of the billboard.

[0024] Then the operator adjusts the position of the inner top plate 22 through the inner top screw rod 21 so that the inner top plate 22 acts on the front wall of the billboard. After the fixation is completed, the installation and fixation operation of the LCD screen is carried out.

[0025] Before installation, the position of the movable seat 51 is adjusted inwardly through the vertical screw rod 52. When the movable seat 51 moves, the movable rod thereon acts on the adjustment long hole 50, thereby causing the rotating tube 4 and the LCD screen to rotate, and finally achieving the purpose of adjusting the deflection angle of the LCD screen and performing the installation operation of the LCD screen.
