Description

Technical Field

[0001] The utility model relates to the technical field of marking rulers, in particular to a folding angle steel marking ruler. Background Art

[0002] Currently, when manufacturing workpieces with angle steel, especially in batch production, the number of marking and measuring movements increases significantly. When using a square or ruler to mark angle steel, each time a 45-degree angle or a "Z" angle is encountered, the ruler or square ruler must be measured, marked, and then adjusted according to the markings to mark the angle. Furthermore, because the square ruler's shape is designed to create a 90-degree right angle, while it is possible to mark a right angle, it requires repeated adjustment of the square ruler and the angle steel to achieve the right angle. Furthermore, the square ruler is prone to shaking and instability during the marking process. All of these factors add to the inconvenience of the marking operation, making the process cumbersome, time-consuming, and labor-intensive. Utility Model Content
