The invention discloses a line-stripping and line-bending dual-purpose portable tool which comprises a lower shearing plate and an upper shearing plate. The tool is characterized in that the lower shearing plate and the upper shearing plate are arranged symmetrically and hinged and fixed through a rotating shaft, the outer walls of a connecting end where the lower shearing plate contacts with the upper shearing plate form a right angle when the lower shearing plate is perpendicular to the upper shearing plate, line stripping grooves which are mutually symmetric are formed in inner side walls, which are opposite, of the lower shearing plate and the upper shearing plate, section of each line stripping groove is semicircular, and an arc-shaped knife head is fixedly arranged at the outer end of each line stripping groove. The line-stripping and line-bending dual-purpose portable tool is simple in structure, low in cost and convenient to carry, quick line stripping can be realized when secondary line connecting and line stripping work is performed on site, uniformity in line stripping length and line bending angle of each guide line is guaranteed, labor intensity of line stripping work is lowered, and line connecting efficiency is improved.
