A high-speed fastening system includes a conventional yoke coupled to a likewise conventional shaft provided with specific fastening elements, via a vertically movable outer casing and a central body into which the shaft is inserted so as to secure the yoke to the aforementioned shaft. The auxiliary components, in addition to those already mentioned, include a catch fitted in the arch of the yoke, an intermediate sleeve inserted into the inner part of the central body, an inner spring situated inside the sleeve, and an outer spring whose ends rest in the arched part of the yoke and in the lower part of the outer casing. The shaft is fitted or dismantled from the interior of the yoke body by conventional ball bearings in combination with an annular zone situated in the insertion zone of the aforementioned shaft. The system, by slight pressure of the shaft downwards towards the yoke body, enables the bearings to be interlocked by insertion with the insertion zone, whereas the shaft can be freed from the insertion zone by an opposite movement, by the downward pressure of the outer casing. |
