Hard tissue cutting device for primary cell culture of schizothoracins

A hard tissue cutting device for primary cell culture of schizothoracins comprises a bottom plate, and a vertical first groove is formed in the top face of the left side of the bottom plate. Fourth grooves are formed in the two sides of the first groove correspondingly, and a second electric telescopic rod, a first electric telescopic rod, a first power device, a second power device, a third powerdevice and a transverse cutting device are connected with a power source and a controller. According to the hard tissue cutting device, metal cutting lines are adopted for vertically and longitudinally cutting the hard tissue of the schizothoracins, the rotation directions of the cutting lines are different, and therefore the cutting lines are effectively prevented from adhering to the hard tissue of the schizothoracins; automatic control is adopted, fine operation is carried out, and deviations generated during manual cutting can be effectively avoided; the manner that a cutting barrel cooperates with a convex plate
