Non-polished surface rapid measuring angle device

Technical Field

The utility model relates to the technical field of angle measuring instruments, in particular to a device for rapidly measuring an angle of a non-polished surface.

Background

The dial indicator is a length measuring instrument which converts a general linear displacement (linear motion) into a rotary motion of a pointer through a gear or a lever and then reads on a dial.
