Abstract
A tubular wrench for screws, characterized essentially by the fact that it consists of a tube whose cavity is identical to the planes of the heads of the screws to be handled, this tube being closed at its rear end and carrying a coil spring therein, limited between its bottom and an end piston, also comprising in the anterior part of the cavity and near the embouchure, two balls arranged in opposite planes, and slightly protruding from them, held elastically for the retention of the head of the screws, which they are arranged inside the pipe wrench, along the entire length of the cavity, and always pushed by the piston, so that the bolt of the last screw is always protruding to the outside, with the head retained by the balls, with which the tool is always ready for the supply of one screw, or to receive another, pushed the one that is protruding.
