The horizontal groove 3 opened on the surface of processing table 1 provides a track for the movement of sliding block 6. First servo motor 4 is fixed outside processing table 1. When first servo motor 4 is started, the rotating power generated by its output end is transmitted to first lead screw 5 through coupling, causing first lead screw 5 to rotate within horizontal groove 3. Since first lead screw 5 is threadedly connected with sliding block 6, according to the screw transmission principle, the rotation of the lead screw is converted into the linear movement of sliding block 6 within horizontal groove 3. The processing plate 7 fixedly connected to the top of sliding block 6 moves together with sliding block 6, thereby precisely adjusting the horizontal position of the sample placed on processing plate 7, meeting the requirements of different tests for sample position. Second servo motor 8 is installed on the top outer wall of L-shaped plate 2. After starting, the rotating movement of its output end is transmitted to second lead screw 9 through coupling, causing second lead screw 9 to rotate within the through hole on the top of L-shaped plate 2. Second lead screw 9 is threadedly connected with sliding seat 10. With the rotation of second lead screw 9, sliding seat 10 moves vertically along second lead screw 9 under the action of threads.
