A pressure mechanism for application to clamps and clamping jacks, essentially characterized in that at the end of the movable arm of the tool a t-head is drilled and axially threaded so that it has a thread for receiving a screw that inferiorly receives a driving handle, the said spindle being extended in another of smaller diameter projecting into the cylindrical interior of a cavity of the t-head itself and in which cavity a cane head is received that threads in the opposite direction to the previous mechanism on the prolongation of the spindle of smaller diameter, with the particularity that this rod presents externally and longitudinally a slot in which the head of a key is lodged that prevents the rotation of the reeds (Machine-translation by Google Translate, not legally binding)
