<p>The invention concerns a spool (4) comprising a support (10) and a reel (11) of suspending thread reserve (5), said reel (11) comprising a pin (27) projecting radially outwards, serving to lock the reel (11) in rotation. The invention is characterised in that the reel (11) is mounted on the support (10) so that its axis is substantially vertical when the spool (4) is suspended; the pin (27) is located in the lower part of said reel (11) when the spool (4) is suspended, and the pin (27) is dimensioned so that the suspending thread (5) passes over it when the spool (4) is suspended and said thread is linked to an object such as a cultivated plant (6) which is suspended thereby.</p> |
