Embodiment：
For the technical characterstic for illustrating this programme can be understood, below by embodiment, and its accompanying drawing is combined, to this reality
It is described in detail with new.
As Figure 1-5, a kind of electric vibrator knife, including vibrations knife rest 1, installation cavity 2 is provided with vibrations knife rest 1,
The fixed motor 3 in one end of knife rest 1 is shaken, the output shaft 4 of motor 3 is stretched into installation cavity 2, one is fixedly mounted with output shaft 4 eccentric
Axle 5, clutch shaft bearing 6 is provided with the eccentric position of eccentric shaft 5, and the inner of clutch shaft bearing 6 and connecting rod is connected, and the outer end of connecting rod is with turning
The inner of spindle 8 is connected, and the outer end of Coupling Shaft 8 is connected with the inner of cutter shaft 9, the outer end of cutter shaft 9 and the inner phase of slitter shaft 10
Even, the outer end of slitter shaft 10 passes through the blade 12 of 11 clamp of cutter holder one.
The connecting rod is made up of con-rod only 7 and semicircle snap ring 13, and con-rod only 7 coordinates clamp with semicircle snap ring 13
On clutch shaft bearing 6, con-rod only 7 and semicircle snap ring 13 are connected by screw rod, and the outer end of connecting rod is provided with connection through hole 14, institute
