Equipment for efficiently and quickly cutting sectional material round hole

The invention discloses equipment for efficiently and quickly cutting a sectional material round hole, and relates to the cutting field. The equipment comprises a main body, wherein the top end of themain body is provided with a through hole. Through an arranged fixing column, ejector pin and spring, before the equipment is used, a cutting head in the equipment needs to be connected with externalgas cutting equipment. When the equipment is used, a worker needs to measure a hole opening position on a sectional material and make a mark, then, the sectional material is put on the bottom of theequipment, the position of the equipment can be regulated through roll wheels, the endpoint of the ejector pin corresponds to a mark point on the sectional material, and meanwhile, an empty cavity positioned in the spring enables the ejector pin to be retracted so as to be used for meeting the requirements of the sectional materials of different thicknesses, applicability is high, and finally, external cutting equipment is
