Electric copper pipe cutting knife

Abstract

The invention discloses an electric copper pipe cutting knife which comprises a cutting knife shell. A device containing cavity is arranged on the left side of the cutting knife shell. A rotating inner shell is arranged in the device containing cavity. A copper pipe containing cavity with the front portion and the rear portion communicating with the outside is arranged in the rotating inner shell.Two knife moving cavities with openings being inward are arranged in the copper pipe containing cavity. A transmission cavity is arranged in the middle of the cutting knife shell. A fan cavity is arranged on the lower side of the transmission cavity. A trigger moving cavity is arranged on the lower side of the fan cavity. A power cavity is arranged on the right side of the cutting knife shell. Alifting mechanism and a cutting mechanism are arranged in the device containing cavity. A trigger mechanism is arranged in the trigger moving cavity. A transmission mechanism is arranged in the transmission cavity. The device is simple in structure and convenient to operate, the device can automatically fix and cut copper pipes, the device is suitable for copper pipes of different calibers and different thicknesses, and then work efficiency is improved; and meanwhile a baffle can protect users, and the life safety of users is protected.

Description

technical field [0001] The invention relates to the field of electric tool design, in particular to an electric copper pipe cutter. Background technique [0002] The copper pipe cutter is a tool used to cut copper, brass, aluminum and other metal pipes. At present, most of the copper pipe cutters are manual. When working, first fix the pipe to be cut, and then place the pipe cutter on the The position to be cut, and tighten the handle, the roller, cutter, and rotate around the outer wall of the pipe. As the cutting thickness increases, the force at the beginning of each rotation becomes larger and larger, which is time-consuming and laborious. When cutting with an electric saw , the cut surface is uneven, there are many burrs, and the efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric copper pipe cutter with a reasonable structure, which can automatically fix and cut copper pipes, has...
