103 are located above datum level, and under both of these case, calculation is identical, provides a kind of calculation herein, utilizes formulaObtain the distance D that corresponding first screw rod 10 in 102 position of the first adjustment hole need to move1, utilize formulaObtain the distance D that corresponding second screw rod 11 in 103 position of the first access need to move2, i.e. the first screw rod
10 need mobile distance identical with the second screw rod, and that only moves is contrary, similarly, here if the length of obliquity sensor
Degree is not equal to the center of the first adjustment hole 102 and the first access 103 away from then can be carried out by the principle of similar triangles
Equal proportion amplification obtains the distance that corresponding first screw rod 10 or the second screw rod 11 need to move.
