Technical Field
The invention relates to the technical field of measuring equipment, in particular to a small object outer diameter measuring instrument.
Background
The vernier caliper is a precision instrument for measuring length, inner diameter and outer diameter, and is widely applied. However, since the contact surface between the measuring claw and the object is narrow, it is difficult to fix the object to be measured when measuring the diameter of a sphere or an ellipsoid or the major and minor diameters of a small irregular object having a nearly spherical shape, and it is difficult to accurately determine the measurement point. Therefore, the operation is inconvenient, time-consuming and labor-consuming, and the error is large. When measuring such objects, the advantage of high precision of the vernier caliper is not exerted, but rather becomes a drawback. Therefore, a measuring tool capable of fixing a measured object well is needed to realize a measuring instrument for accurately and rapidly measuring the length and the outer diameter of a small object.
