Description

Technical Field

[0001] This utility model relates to the field of measuring rulers, and in particular to a novel rack and pinion micro-motion mechanism for single-column height rulers. Background Technology

[0002] Existing technology: Currently, the frame of single-column height gauges on the market needs to slide on the body, mainly by pulling the frame up and down by hand or by using gear and rack transmission.

[0003] The disadvantages of existing technology: The disadvantage of manually pulling the ruler frame is that the position is not accurate. Whether it is marking or measuring, it is very difficult to grasp the distance when pulling the ruler frame to the designated position, and the calculation is difficult.

[0004] Rack and pinion drives offer accurate positioning, but require prolonged cranking for long distances, which is time-consuming and labor-intensive.
