[0021] A gauge adjustment mechanism for a railway track inspection instrument calibration table includes a calibration table 1. The calibration table 1 has a through-hole mounting groove 11. A lead screw 2 is rotatably mounted within the mounting groove 11. A lead screw slide 3 is fitted onto the outer surface of the lead screw 2. A table rail is fixedly mounted on the upper surface of the lead screw slide 3 and the right side of the upper surface of the calibration table 1. The lead screw slide 3 is T-shaped and slidably mounted within the mounting groove 11. U-shaped shells 5 are fixedly mounted on both the left and right surfaces of the lead screw slide 3. The U-shaped shells 5 are threadedly connected to the lead screw 2, and a solution cavity is formed between the U-shaped shells 5 and the outer surface of the lead screw slide 3.
