Mechanism of aim for mortars, that is characterized because the tube of the mortar wears a sliding collar only joined to the assembly by a shank-pivot that crosses a beam by a longitudinal draft, supporting the tube, through the collar, in a chamfer that presents the beam, which also has a shaft attached to the tripod, on which it can rotate freely allowing the collar to take all the slopes, and by the longitudinal movement of the rod-pivot along the broth of the joist, the collar and the same tube acquires the appropriate inclination in relation to the beam axis with the tripod made by the telescopic parallel arms controlled by the height steering wheel, which in its movement keep the parallelism between the beam and the horizontal axis of the tripod.
