Utensil is examined to slide caliper rule

The utility model relates to an utensil is examined to slide caliper rule, including the first utensil of examining, the first base member of examining the utensil including two separation, every base member includes first base, the piece is surveyed on first plane, first slider and first retaining member, first plane surveys that the piece is movably locates first base, first slider is connected in first retaining member, first retaining member can remove in order to promote the survey block move of first plane through first slider by base first relatively, and can survey the position of piece in order to inject first plane in base first relatively location, thereby two base members symmetry sets up and makes two first planes survey the piece relative and establish. Adopting this utensil is examined to slide caliper rule's the first utensil of examining, because two base members separate, consequently can surveying on two first planes as required and place the gage block that quantity is different with the s
