2. when the reaction cup is manually replaced, the whole reaction cup needs to be taken out of the circular positioning groove and then inserted into another reaction cup, the distance between the taking-out and the insertion is long, and the reaction cup is inconvenient to replace;

3. the vertical direction of the reaction cup is positioned by the contact of the lower plane of the flange and the fixed disk, and the problem is more prominent as the flatness of the lower plane of the flange is difficult to ensure and the reaction cup is longer. Therefore, the vertical orientation of the reaction cup is not ideal;

4. the radial direction and the tangential direction of the circumference of the reaction cup are positioned by the matching degree between the shape of the reaction cup and the arc-shaped groove of the fixed disk, the positioning is inaccurate, the center of the light beam is easy to deviate from the center of the optical surface of the reaction cup, and the measurement error is generated.
