Abstract:
A rotary coupling head for use with a portable cutting device has a blade-supporting housing, an axial motor drive shaft connected to the blade-supporting housing so as to be rotatable with the blade-supporting housing, an interchangeable cutting blade mounted on the blade-supporting housing so as to rotate with the rotation of the blade-supporting housing. The cutting blade is engaged around the drive shaft such that the cutting blade and the housing are axially displaceable along the drive shaft. A coupler on the housing is automatically actuated upon the axial displacement of the cutting blade and the housing on the drive shaft.
