Abstract

The current marking gauges, mortise gauges and circle marking gauges on the market require use of a ruler to measure distances prior to marking, which is inconvenient and time consuming. Moreover, the accuracy of the marked dimension is inexact due to the low accuracy of using a ruler. Furthermore, parallax error created by transferring the measured distance between the rule and the gauges also needs to be accounted for, which reduces accuracy even further. This present invention helps to improve the accuracy of the measurement and marking of the gauges, increases efficiency, convenience, saves time and is easy to use. The new product is a digital multifunctional marking gauge, that includes a Digital Unit, Main Slider, Beam, Display, Fixed Pin, Adjustable Pin, Adjustment Slider, Fence, Calibration Frame, Calibration bar, Setting Block, Scriber, Set function button of the Digital Unit, Locking Screw, Fixing Screws and related components.
