Description

Multifunctional caliper

Technical Field

The utility model relates to a measuring tool especially relates to a multifunctional caliper rule.

Background

The current widely used caliper generally consists of a main caliper, an auxiliary caliper, a depth gauge, an inner caliper group and an outer caliper group. The auxiliary ruler is shorter than the main ruler, the auxiliary ruler is in the shape matched with the main ruler, the auxiliary ruler is clamped and tightly attached to the outer wall of the main ruler, the auxiliary ruler is provided with a fastening position, and the auxiliary ruler can be fixed on the main ruler when the auxiliary ruler moves in place on the main ruler. The depth gauge is arranged on the inner wall of the auxiliary gauge and is parallel to the main gauge, a groove corresponding to the position, shape and size of the depth gauge is arranged on the outer wall of the main gauge, and when the auxiliary gauge moves on the main gauge, the depth gauge is kept in the groove and moves along with the auxiliary gauge. The comparison documents were as follows:

reference 1(CN2831040Y) discloses a caliper which can have both measuring and writing functions and is more convenient to carry. The caliper is a hollow cylinder with a plane scale surface, the auxiliary ruler is in a shape matched with the main ruler, the auxiliary ruler is clamped and tightly attached to the outer wall of the main ruler, the depth ruler is installed on the inner wall of the auxiliary ruler and is parallel to the main ruler, the outer wall of the main ruler is not provided with a groove corresponding to the position and the shape and the size of the depth ruler, when the auxiliary ruler moves on the main ruler, the depth ruler is kept in the groove and moves along with the auxiliary ruler, a pen is arranged in the cavity of the main ruler, and the pen point extends out of the cavity of the main ruler. The depth gauge can be folded to shorten the length, the outer measuring claws of the main gauge and the auxiliary gauge can be folded towards the inner measuring claw, and a hook is arranged on the outer wall of the back of the auxiliary gauge.
