CN205505885U - Smooth internal limit gage of nanocrystal - Google Patents

Abstract

The utility model relates to a smooth internal limit gage of nanocrystal, measure piece and middle part air level including metal hand shank, crystal, metal hand shank's both ends install a crystal respectively and measure the piece, the middle part air level set up the middle part at metal hand shank, metal hand shank's tip is provided with the tip air level. The utility model has the advantages that: the setting of piece is measured to the crystal, prevents the collision of work piece and feeler gauge, has prolonged life, the setting of middle part air level and tip air level simultaneously, observational level degree that can be better.

Description

The smooth internal limit gage of nanocrystal

Technical field

This utility model relates to a kind of feeler gauge, particularly a kind of smooth internal limit gage of nanocrystal.

Background technology

When using feeler gauge that workpiece to be measured is measured, need feeler gauge directly to contact with workpiece, will fill in When rule are filled in parts, easily producing collision with feeler gauge, cause and create abrasion, service life is short so that measurement data is inaccurate Really；Can not accurately show simultaneously for levelness.

Summary of the invention

For overcoming the defect of prior art, this utility model provides a kind of smooth internal limit gage of nanocrystal.This practicality is new The technical scheme of type is: the smooth internal limit gage of nanocrystal, including metal handle, crystal measurement block and middle part air level, described The two ends of metal handle be separately installed with a crystal measurement block, described middle part air level is arranged on the middle part of metal handle； The end of described metal handle is provided with end air level.

The utility model has the advantages that: the setting of crystal measurement block, prevent the collision of workpiece and feeler gauge, extend the use longevity Life；Air level and the setting of end air level in the middle part of Tong Shi, can more preferable eye-level degree.
