[0002] Steel structures refer to buildings or engineering structures that use steel as the main structural material. They are usually composed of steel columns, steel beams, steel plates, steel pipes, etc., and are assembled by welding, bolt connection or other methods. Steel structure processing involves cutting, welding, forming and assembling steel to manufacture various steel structure components and parts for industrial and construction purposes.

[0003] When steel structures are assembled by bolt connection, holes need to be drilled at specific positions on the steel structures. The drilling head of the drilling equipment acts on the steel structures. However, since the required hole diameters of different types of bolts are different, different types of drilling heads need to be replaced during punching. Generally, the drilling heads are fixed in the drilling equipment, and it is time-consuming and laborious to disassemble and replace them. Repeatedly replacing the drilling heads will increase the labor intensity of people's operations and also have a certain impact on the processing efficiency of steel structure parts.

[0004] In view of the above-related technologies, the inventor believes that there is a defect that it is not convenient to replace the drilling head when the drilling equipment punches steel structure parts.
