[0002] Steel is a material of a certain shape, size and performance made from ingots, billets or steel through pressure processing. Most steel processing is done through pressure processing, which causes the processed steel (billets, ingots, etc.) to undergo plastic deformation. According to the different steel processing temperatures, it can be divided into cold processing and hot processing. Channel steel is a long strip of steel with a grooved cross-section. It is a carbon structural steel for construction and machinery. It is a complex cross-section steel with a grooved cross-section. Channel steel is mainly used in building structures, curtain wall projects, machinery and equipment, and vehicle manufacturing.

[0003] When cutting the channel steel, the operator is usually required to draw lines on the inner cavity of the channel steel to facilitate the subsequent cutting operation. However, when drawing lines, the operator is usually required to press the positioning block on one side of the inner cavity of the channel steel with one hand, and then use the other hand to hold the movable arm on one side of the positioning block. A drawing pen is connected to one end of the movable arm. The drawing pen is used to draw lines on the inner cavity of the channel steel. If the positioning block is not pressed or loosened during the drawing process, it is easy to cause deviation in the drawing, affecting the subsequent cutting operation. In order to facilitate the drawing operation on the inner cavity of the channel steel, a drawing mechanism for steel processing and cutting is provided. Utility Model Content
