Device for removing oxide skin on electro-fusion welding surface of PE pipe and using method

The invention provides a device for removing oxide skin on an electric fusion welding face of a PE pipe and a using method, the device comprises a movable sleeve, a mounting shell and a cutting assembly, the PE pipe is arranged in the movable sleeve in a penetrating mode, and the movable sleeve can rotate around the axis of the PE pipe; the mounting shell is arranged on the outer wall of the movable sleeve and is communicated with the movable sleeve; and the cutting assembly is arranged in the mounting shell, and one end of the cutting assembly extends into the movable sleeve to scrape oxide skin on the outer wall of the PE pipe. According to the device, through the cooperation of the cutting assembly, the movable sleeve and the mounting shell, the cutting assembly scrapes oxide skin in the circumferential direction of the PE pipe, operation is easy, and efficiency is high; besides, under the limiting effect of the mounting shell, the cutting assembly cannot do linear motion in the radial direction of the PE
