The invention discloses tube drawing pliers, and relates to tube drawing pliers for a tube drawing mechanism of a water-cooled metal centrifuge. Because the traditional tube drawing pliers are difficult in assembly and disassembly and have long assembly and disassembly time, the production efficiency is affected. In order to solve the technical problems, the invention provides the tube drawing pliers convenient for assembly and disassembly. The tube drawing pliers comprise a tube drawing pliers head, a connector and a cylinder. The tube drawing pliers are characterized in that: the tube drawing pliers head and the connector are clamped, and the connector is movably connected with the cylinder. The time of replacing the tube drawing pliers can be saved, and the labor intensity is reduced.
