Symmetrical appearance device of machinery

The utility model belongs to the technical field of measuring equipment, concretely relates to symmetrical appearance device of machinery, the major structure includes the base, first through -hole, the second through -hole, the altitude axis, a screw, the reader, the dead lever, a display screen, the third through -hole, no. Two screws, the antiskid line, the fourth through -hole, a bearing, a button, the rotation axis, the setting chi is restrainted to the needle, the extension is detained, five -way hole and no. Three screws, restraint the needle that can carry out 360 rotary motion among the prior art on the setting chi is connected to the reader, and simultaneously, about can going on on the altitude axis, the reader slides with fixed, the rotation angle who restraints the setting chithrough the height and the needle of regulation reader comes the height of rapid survey car fatlute model surface physique characteristic and the rotation angle parameter that the setting chi was restrainted to the needle, i
