description	The utility model relates to a pipe bender, which is characterized by mainly consisting of a framework, an oil cylinder, a rotary crank, an arc fixed pulley, a roller and a fixed support. The fixed support is fixed on the top of a worktable of the framework, the arc fixed pulley is in pin joint with the fixed support, the front of the rotary crank is in pin joint with the arc fixed pulley coaxially, the roller is in pin joint with the rotary crank and on the same axis with the arc fixed pulley, the rear end of the rotary crank is in pin joint with a piston rod of the oil cylinder, the oil cylinder is fixedly connected with the worktable of the framework, and a stopper is arranged on the top of the worktable of the framework parallel to the axis of the piston rod of the oil cylinder. The pipe bender has the advantages that the pipe bender can bend pipes in an arc cold manner along a fixed arc clamping fixture by utilizing the oil cylinder as propelling force and can be placed on a construction site or a rivet
