Abstract: A rotary cutting head adapted to allow a flexible strand of cutting wire to be inserted therein has a coupler for coupling the cutting head to a driveshaft of the motor, a support, and a clamping mechanism supported by the support in the rotary cutting head. The clamping mechanism is adapted to clamp the strand within the exterior housing. The clamping mechanism includes squeezing cams mounted so as to pivot in parallel planes therebetween and relative to the rotation axis of the cutting head. The support is axially translatable in the exterior housing. An application of actual movement in a direction opposite to the housing and the support causes a raising of the squeezing cams or a lowering of the squeezing cams.
