The invention discloses a hydraulic oil pipe inner cutting knife which comprises a cutting knife body, wherein an upper connecting end is arranged at one end of the cutting knife body; a lower connecting end is arranged at the other end of the cutting knife body; a water inlet passage, a pressurizing passage and a pressure adjustment screw mounting cavity are arranged in the cutting knife body; a pressure adjustment screw mutually matched with the pressure adjustment screw mounting cavity is in threaded connection with the pressure adjustment screw mounting cavity; a pressure adjustment passage is arranged in the pressure adjustment screw; a pressure adjustment screw fastening groove communicated with the pressure adjustment passage is formed in the lower end of the pressure adjustment screw; a plurality of cutting knife mounting cavities and guide sleeve mounting cavities communicated with the water inlet passage are arranged in the cutting knife body; guide sleeves mutually matched with the guide sleeve mounting cavities are in threaded connection with the guide sleeve mounting cavities; mounting cavities and limiting convex edges are arranged in the guide sleeves; guide sleeve fastening grooves are formed in the outer sides of the guide sleeves; cutting knives and compression springs are arranged in the cutting knife mounting cavities.

The invention provides an ultrasonic cutting mechanism for ear hooks and nose wires for a full-servo mask, which belongs to the field of mask processing and includes an ultrasonic cutting mechanism. The bottom of the ultrasonic cutting mechanism is fixedly supported by a cutter supporting mechanism. The transportation mechanism is fixedly installed at each corner, and the traction mechanism is fixedly installed in the middle of the bottom end of the ultrasonic cutting mechanism. The present invention uses the ultrasonic cutting mechanism, body, ultrasonic generator and ultrasonic horn to facilitate High-intensity ultrasonic cutting energy is generated at the place, and the energy is converted into high-frequency ultrasonic vibration by the transducer, so as to be transmitted to the ultrasonic horn, and then transmitted to the ultrasonic cutter by the ultrasonic horn. The high-frequency vibration generated by the ultrasonic cutter can achieve the purpose of ultrasonic cutting when the ear hooks and nose wires to be cut touch.
