Description

technical field [0001] The invention belongs to the technical field of scribing tools, in particular to a self-centering multi-purpose scribing ruler for round holes that is positioned at the center of the hole to draw a circumferential line and equally divided. Background technique [0002] Marking is often required in the process of machining. When positioning and dividing the circumference of holes with different diameters, different measuring tools are needed, which is inconvenient to operate and difficult to guarantee the marking accuracy. There is no comparison Ideal product to meet machining needs. Contents of the invention [0003] In view of the deficiencies in the prior art above, the object of the present invention is to provide a round hole self-centering multi-purpose marking ruler with convenient operation, high marking precision, and accurate equalization. [0004] For realizing above-mentioned technical purpose, the technical scheme that the present invent...
