摘要

The box has a fork (7, 8) with an indexing system having two balls (16, 17) diametrically opposed around an axle (6). Forces applied by the balls to the axle are in opposite directions such that resultant movement of the forces on the axle is null. The axle has three contact areas (21, 22, 23) at its surface to immobilize the fork (7, 8) when the balls engages in their respective contact areas.
