Polypropylene random copolymer/ poly ethylene (PPR/PE) pipeline repair tool

The invention relates to a polypropylene random copolymer/ poly ethylene (PPR/PE) pipeline repair tool which is mainly formed by a hot melting device and a hot melting rod. The hot melting device mainly comprises a main body, a female die and a male die. The main body is a heating plate; an installation hole is formed in the main body; the female die is detachably connected onto the main body, canconduct heat, and is formed by a cylinder and an incomplete cylinder; axes of the cylinder and the incomplete cylinder coincide; a part, directly contacting the main body, of the female die is the incomplete cylinder; the cylindrical surface of the incomplete cylinder is sectioned by a plane parallel to the axis of the incomplete cylinder; a stepped through hole is formed in the sectioned plane;a hole with a small hole diameter is intersected with the sectioned surface; and the stepped through hole and an unthreaded hole of the concave die are connected to two sides of the main body throughbolts. The length of the cy
