The invention relates to a cutter shaft of a crusher. The cutter shaft comprises a main shaft, wherein a front end face baffle plate and a rear end face baffle plate are arranged on the main shaft and are correspondingly arranged at two ends of the main shaft. A first front tool rest, a first rear tool rest, a second front tool rest and a second rear tool rest are sequentially arranged between the front end face baffle plate and the rear end face baffle plate on the main shaft. The first rear knife rest and the second front knife rest are arranged in the middle of the main shaft in an overlapped mode, and the first front knife rest and the second front knife rest are sequentially provided with a special-shaped knife A, a special-shaped knife B, a special-shaped knife A and a special-shaped knife B in the circumferential direction. According to the scheme, through the arrangement method of axial overlapping and tangential dislocation of the knife rest set, namely the arrangement mode of the first front knife rest, the first rear knife rest, the second front knife rest and the second rear knife rest, the special-shaped knife A and the special-shaped knife B which are arranged on the first front knife rest and the second front knife rest are partially crossed and overlapped with the special-shaped knife A and the special-shaped knife B which are arranged on the first rear knife rest and the second rear knife rest, so that axial clearances between cutters in the same group can be avoided, and the cutting efficiency is improved. The cutting effect is good, the instant impact in the cutting process is lower, the vibration is smaller, the service life of equipment can be effectively prolonged, the noise is lower, and the noise pollution of the equipment is reduced.
