[0002] Currently, a Chinese patent with publication number CN 216490659 U discloses a device for detecting defects in the appearance of a mobile phone, comprising a base, a hydraulic cylinder provided on the surface of the base, a box provided at one end of the hydraulic cylinder, and a box door provided on the top of the box. The interior of the box is illuminated by a lighting lamp, and by providing multiple lighting lamps, the lighting inside the box can be more sufficient. The situation inside the box is photographed by a camera and projected onto a display screen for easy observation by inspectors. By providing multiple cameras, the mobile phone can be photographed from multiple angles to prevent missing details that affect the inspection effect. The fixed plate is moved by an electric push rod, and the two ends of the mobile phone are fixed to the surface of the placement plate. The box is raised and lowered to a suitable height by the hydraulic cylinder and the hydraulic rod, thereby raising and lowering the display screen to a suitable height, so that the height of the display screen can be raised and lowered according to the height of the inspector, making it easier for the inspector to observe.
