Product name: Multi-functional line ruler Size: 173.17*75*100mm/6.82*2.95*3.94 inches Thickness: 1.2mm Product model: D01 Material: stainless steel 45 degree accuracy 100mm 0.05mm 67.5/77. 47/60/54 degree accuracy 100mm 0.55mm 90 degree accuracy 75mm 0.03mm Product features: Two rows of hexagonal holes are used for marking the hole ruler; 90-degree line: a vertical line or two vertical lines crossed; 135 degree crossing: can be used for 45 degree or 135 degree crossing or two faces crossing the line; 67.5 degree lines: can be used for octagon lines; 77. 47 degrees 1:4.5 marking: can be used for dovetail marking; 60-degree lines: can be used for hexagonal lines; 54 degree lines: Can be used for pentagon lines Advantages: 1. Welding structure optimization: the innovative use of back-up and seam welding structure, optimize the grooving process, increase the perpendicularity guarantee, improve the overall structure strength and service life; 2. Thickness optimization: the ruler seedling is changed to about 1.2mm thickness, which is more suitable for manual pencil, pen and other marking operation, improving convenience and accuracy; 3. Backrest width optimization: the backrest width is changed to 18mm width, which increases the stability and operability of the backrest, and the single-side backrest is more stable and convenient when leaning on the wood side; 4. Add stamp positioning marking holes: add 2 rows of stamp holes to slot, different from the previous hole ruler, also different from the round hole marking ruler, this stamp hole has an automatic center function, and can make the pencil pen tilt way according to the ergonomic characteristics of marking, avoiding the shortcomings of the traditional vertical hole pencil is easy to break, a good solution to the problem of inaccurate and inconvenient marking; 5. Increase the Angle of no line on the market: Increase the new line Angle of 67.5°/77.47°/60°/54°/135°/90° and other stainless steel wire ruler on the market, which can easily solve the line work of common woodworking furniture.
