The chuck device comprises clamp elements (4,5,6) having, at one end, an underlying tooth (8) and a conical surface (7) conjugated with the surface of the cell (2); the clamp elements (4,5,6) are uniformly distributed on the circumference of a plate (3), comprising a surface (3a) for the resting of the bottom (2a) of the cell (2), to which they are pivoted so as to be rotatable in radial planes, means (14) being present for locking the clamp element (4,5,6) in the closure position. |
