Abstract
A device is essentially formed by a wrench to be inserted on the bolt head, a series of demultiplier means housed between them, a lever operable alternately in one or the other direction, the angular exertion of the lever being limited by a limiting element so that the lever can function as a ram, as well as a support on the ground to prevent rotation of the device around the bolt. The limitation element of the operating lever of the device is essentially formed from a plate equipped with two projections arranged on the far ends of said plate, which is connected outside of the body of the device to one of the demultiplier means provided in the body. The demultiplier means are formed from a series of gears fitted one in the other, the last of the series of gears being connected to the wrench situated outside of the body or a system or several planetary systems in series and parallel or by using an endless screw with a toothed crown. <IMAGE>
