Description
Technical field
Survey tool technical field is the utility model is related to, more particularly to a kind of vernier caliper.
Background technology
Vernier caliper, is a kind of measurement length, internal-and external diameter, the measurer of depth.Vernier caliper mainly by main scale and is attached to master
On ruler and can slide vernier two parts composition.Usually when measurement, in the measurements, survey crew passes through vernier calliper
The scale that clamp nut on ruler comes out vernier caliper measurement is fixed, and to prevent there is deviation when scale is read, leads
There is deviation in the size for causing finally to measure, so that follow-up certain operations are influenced, in the prior art, the vernier calliper occurred
The clamp nut of ruler is all disposed within the top of vernier caliper, if in the internal diameter of one parts of vernier caliper measurement, Ren Mentong
Touching for often can not be successfully adjusts clamp nut to fix scale, causes the time-consuming of measurement, while also inaccurate there is measurement
The problem of true, and the clamp nut of the prior art adjust it is fixed after, due to the frictional force of clamp nut and main scale not
Foot, however it remains situation about slide, cause the deviation of measurement；It is multiple due to needing to measure in measurement process, then will
The value repeatedly measured is averaged, using average as last measured value, due to when measuring a parts, due to
The deviation of its diverse location is all smaller, and in existing vernier caliper, after measuring a sub-value, after clamp nut tune pine,
The fine setting of size is carried out again to meet measurement request, and in trim process, clamp nut can still have the main scale of vernier caliper
One frictional force, since clamp nut material is hard, when adjusting scale, is very easy to cause to master due to sliding clamp nut
The scuffing of ruler, reduces the service life of vernier caliper；When measurement, vernier caliper often slides, and leads to not normal
Measurement, there is measure it is inaccurate the problem of, while also add people measurement man-hour.
