[0002] With the development of society, industrial construction is becoming more and more massive, and the quality requirements for construction projects are getting higher and higher. As one of the basic raw materials for construction projects, the quality of steel must be guaranteed to meet strict standards. Therefore, before the construction project steel is put into use, it is often necessary to conduct tensile and compressive tests on it. Before the test, it is usually necessary to use marking equipment to mark the steel for tensile test samples. For example, as shown in the existing patent technology: after searching, the China Patent Network discloses a steel bar marking machine for construction steel engineering inspection (public announcement number CN212735755U). When this type of device is used, the adjusting gear is driven to rotate by turning the handle. Since the adjusting gear and the transmission gear are meshed with each other, it can drive the transmission plate to move axially, that is, the adjusting plate and the marking rod are axially slid along the slide rail. When the marking head of the marking rod contacts the steel bar body, the handle is continued to be turned to apply external force to achieve the marking action on the steel bar body.

[0003] However, there are still some shortcomings in the above-mentioned public patents and the construction engineering steel marking machines adopted in the existing market: the existing method of manually pressing down to move multiple groups of marking rods downward to mark steel, which can usually only mark single spacing when marking, and the marking performance for steel bars is relatively single and not flexible enough. To this end, those skilled in the art provide a steel bar marking device for construction engineering steel inspection to solve the problems raised in the above background technology.
