As shown in Figs. 3 to 9, in general, each of the spline output shaft 11, which is connected to the power transmission device 10 for driving the external device of the manager and finally outputs the rotational driving force generated in the engine, respectively rotates. Drivenly connected, the spline groove is formed in the inner axial direction at the center of the axis of the main body 20 to enable spline coupling in the axial direction to the spline output shaft 11, the hammer type on the outer peripheral surface of the main body 20 Each of the cutters 30 is rotatably provided by the hinge 21 as a basic feature of the technical configuration.

Here, the main body 20 is formed as a shaft having a circular cross section of a predetermined diameter, the female spline is formed in the inner axial direction so that a few splines of the output shaft is intermittently inserted in the axial direction and interlocked at the center of the shaft. A female screw hole is formed in which the female spline groove and the outer circumferential surface communicate with each other, and a fixing bolt 22 serving as a key is fastened to the female screw hole.

In addition, hinges 21 are provided on the outer circumferential surface of the main body 20 at predetermined intervals along the axial direction and at intervals of a predetermined angle along the rotational direction.
