The invention relates to a multipurpose pipe bender which comprises an operation platform, an actuator coupling, an electrical actuator, a buffer pipe bending mechanism, a line pipe bending mechanism, a clockwise switch and a reversing switch, wherein the buffer pipe bending mechanism comprises a buffer die, a pipe passing guide rail for providing a supporting force for a buffer and a buffer fixing bracket; the line pipe bending mechanism comprises a line pipe bending die and a line pipe clamping device for providing a supporting force for a line pipe. The multipurpose pipe bender has the beneficial effects that an effect of bending out the round 540-degree buffer in a cold bending manner can be implemented by the buffer pipe bending mechanism; cold bending of pipes with various diameters, such as a galvanized pipe, an iron pipe and a steel pipe, at a random angle can be implemented by the line pipe bending mechanism; the buffer die and the line pipe bending die also can rotate forwards or reversely; the multipurpose pipe bender is easy and simple to operate and enables the pipe to be difficult to thin and deform; the conducting effect and rust prevention capacity of the pipe are improved.
