The bottom of base 21 may be reinforced with a network of ribs 22 and may also include feet (not shown) for resting on the ground. The base 21 may include an axially extending, approximately annular flange 23 defining a space 24 . The opening 25 of the nearly annular flange 23 has opposing edges 26 and 27 .

A turntable 28 is mounted to the base 21 for rotation about the axis 15 , the turntable 28 rests on the base 21 and is received in the space 24 so as to be positioned by the nearly annular flange 23 . A bore 38 extends axially through the turntable 28 . The turntable 28 has a handle 29 by means of which it can be rotated manually, which protrudes radially beyond the peripheral edge 30 . This handle 29 protrudes through the opening 25 , opposite edges 26 and 27 of said flange 23 providing a stop against the handle 29 to limit the rotation of the turntable 28 about the axis 15 .

Three equiangularly spaced ramp structures 31 may be provided on the upper side of the turntable 28 , each ramp structure 31 having a respective circumferentially inclined surface 32 . Each inclined surface 32 may extend circumferentially between a respective first and second contact surfaces 33, 34, which are generally parallel and axially spaced.
