Subsequently, the support base 42 continues to move upward, bringing the LCD screen to the outside of the conveyor frame 32. The flip motor 62 drives the connecting base 48 to rotate through the support tube 49. The connecting base 48 realizes the synchronous flipping of the retractable base 54 through the spacing adjuster 70. The position of the adsorption component 46 is fine-tuned by the spacing adjuster 70 so that the LCD screen is located directly above the casing.
