The coincident position is the fixed position of the auxiliary plate, and the calibration of the angle of the auxiliary plate and the object to be calibrated is completed; if the object to be calibrated is collided and the angle is offset, the object to be calibrated is adjusted until the line of sight of the telescope through the crosshairs coincides with the crosshairs of the objective lens target, and the light beam of the laser transmitter coincides with the cursor hole, thereby resetting the object to be calibrated. By setting the combination of the telescope and the laser transmitter, the accuracy of angle calibration and resetting is improved.
