Impact screwdriver

The screwdriver to hit is a tool that allows to unlock the screws before dispelling them. It consists of a handle on which you can adapt different flat or cruciform tips (following the screw model). l works by hitting it with a hammer. An internal mechanism transforms the force of the impact into two combined actions: a rotational motion (sliding) and the stitching on the screw (avoid that the ripe tip) once the screw is "dislocked" its dipped with a normal screwdriver is much easier.
