Abstract
This device comprises a driving shaft, which is rotary on itself around a central axis and which is secured to a head for driving the tool into rotation around the axis, the tool being added onto the driving head in a removable way. The driving head includes a driving hub which is adapted so as to be engaged with a driven hub of the tool in order to transmit a rotary movement between them. The driving head is provided with locking centrifugal weights for the tool on the driving head, said centrifugal weights being moveable, under the effect of a centrifugal force resulting from the setting into rotation of the driving head by the driving shaft, between a rest position, in which the centrifugal weights do not interfere with the driven hub, and a position of use, in which a portion of each of the centrifugal weights is brought closer to the central axis and mechanically cooperates with the driven hub in order to maintain it engaged with the driving hub.
