Manual press, counting with a base and a hollow column, able to house said column a piston rod operable by rack and pinion, the rack being carved on the rod itself and permanently coupled to the pinion, which is rotated by angularly actuating a lever of which said pinion is part, all of which proves the understanding of a spring that tries to keep the stem in its highest position with respect to the column through which it slides, essentially characterized because in opposition to the rack the shank presents in the direction of its generator a keyway in which a key is placed in the shape of a t, with its vertical section and coupled in a hole made radially in the wall of the alternative sliding column. Of the shank, being arranged to receive the threading of a nut that immobilizes it, and consequently to the key in question, in said hole to prevent the movement of the repeated shank around its own axis.
