After the threaded rod 7 rotates, it drives the moving block 8 to move. After the moving block 8 moves, it drives the distance sensor 14 clamped on the positioning plate 13 to move, so that by measuring the output value of the distance sensor at different positions, it is convenient for the staff to complete the calibration work of the distance sensor, and the speed of the equipment to calibrate the sensor is improved. The threaded rod 7 drives the rotating shaft 15 to rotate while rotating. After the rotating shaft 15 rotates, it can drive the position sensor 27 clamped between the two clamping blocks 26 to rotate, so that it can drive the position sensor 27 to rotate to different positions, and complete the calibration work of the position sensor 27 according to the output values ​​of the position sensor 27 at different positions.
