When in use, place the test object B on the upper translation stage A3. The two adjustment parts A 5 are screwed in or out to push the upper and lower translation stages A3 and A4 to linearly translate in the fixed seat A2 to form an arbitrary point adjustment and positioning of the biaxial second degree space, so that the object B can be measured. Fine adjustment to the best position. The upper and lower translation stages A3 and A4 need to be moved in the fixed base A2, while the upper and lower translation stages A 3, A 4 and the fixed base A 2 are fixed by other mechanisms, as shown in the second figure, using screws A6 fixes the upper and lower translation stages A3, A4 and the fixed base A 2, but in order to ensure that the translation stage can move smoothly in the fixed base, and to avoid the excessive locking pressure of the screws, the translation stage cannot move smoothly, resulting in a stuck phenomenon. Or, due to insufficient locking pressure, the translation stage is loose and cannot reach the required position accurately, so the screw locking needs to be adjusted more precisely to maintain
