At the same time, the positioning block 224 will insert into the inside of the positioning slot 223 to position the positioning cross beam 213. Then cover the top plate 222 and fix the top plate 222 through the buckle 221 to prevent the top plate 222 from falling off from the inside of the positioning slot 223. Then pick up the liquid crystal display and place both ends of the liquid crystal display inside the sliding groove 2110 and separate multiple liquid crystal displays through the movable block 215. Then move the movable block 215 so that the movable block 215 closely adheres to the outside of the display. Then rotate the adjusting screw 212 to drive the movable plate 219 to move forward so that the movable plate 219 adheres to the front side of the movable block 215 to fix the position of the movable block 215. Then rotate to drive the pressing plate 2111 to press down and adhere to the top surface of the movable block 215 to fix the movable block 215, preventing the liquid crystal display screen from shaking during transportation and causing damage.
