The two clamping plates 17 are arranged in a mirror image. Through the arrangement of the clamping assembly, the LCD display placed on the detection table 1 can be clamped and fixed, and through the arrangement of the two rubber pads 18, the friction between the two sides of the LCD display and the two clamping plates 17 is increased, thereby improving the stability of the LCD display itself during the detection process.
