ABSTRACT:
A blade mounting device is operable for mounting a blade on a drive shaft of a cutting tool which is moved in a predetermined motion for a cutting operation. The blade mounting device includes an operation knob mounted on a body of the cutting tool and adapted to be rotated by an operator. An actuation rod is mounted on the drive shaft and is movable with the drive shaft and rotatable relative to the drive shaft. A holder device is mounted on the drive shaft for holding and releasing the blade in response to the rotation of the actuation rod relative to the drive shaft. A connection member is rotatable with the operation knob and is disposed on the same axis as the actuation rod. A connecting mechanism is provided for connecting the connection member and the actuation rod to each other, so that the connection member and the actuation rod are axially movable relative to each other and are rotatable together with each other. The connecting mechanism includes a shaft provided on one of the connection member and the actuation rod and includes an axial hole provided on the other for receiving the shaft.
