[0029] The utility model discloses an instrument for cutting materials based on ultrasonic technology, such as Figures 1 to 3 shown, which includes an ultrasonic transmitter 1. A base 10 is provided at the bottom of the ultrasonic transmitter 1. The ultrasonic transmitter 1 can be installed on the base 10 at multiple angles, enabling it to change angles to adapt to cutting operations in different directions. The base 10 is a prior art. The ultrasonic transmitter 1 includes an ultrasonic transducer 2, a horn 3, and a drive power supply 4. The drive power supply 4 is electrically connected to the ultrasonic transducer 2 to provide the electrical energy required for operation. An adjustable button 9 is provided on the drive power supply 4, enabling the operator to adjust the frequency parameters. Specifically, by rotating the adjustment button, the output frequency of the ultrasonic transducer 2 can be adjusted. For example, when cutting thinner materials, the frequency can be reduced to increase the cutting speed; when cutting thicker materials, the frequency can be appropriately increased to provide greater cutting force. This flexible frequency adjustment mechanism enables the operator to quickly adjust according to specific requirements, thereby improving the cutting quality and efficiency. The ultrasonic transducer 2 is respectively connected to the horn 3 and the drive power supply 4, converting electrical energy into ultrasonic mechanical vibration. A blade 5 is provided at one end of the horn 3 away from the ultrasonic transducer 2. The blade 5 includes two aspects: the selection of material and the shape design. Cemented carbide is the preferred material for the blade 5 because of its extremely high hardness and wear resistance, which can maintain good cutting performance for a long time. In addition, the surface of the blade 5 can be coated to further enhance wear resistance and corrosion resistance, thereby increasing the working life of the blade 5. The cutting edge 7 of the blade 5 is straight. This design not only has a fast cutting speed but also a straight cutting line and is not prone to deviation. The cutting edge 7 performs high-frequency vibration under the action of ultrasonic waves, further improving the cutting efficiency and quality. Two hook grooves 8 for disassembly are provided at the end of the blade 5. The position and shape of the hook grooves 8 are designed according to needs. The hook grooves 8 not only facilitate disassembly using tools but also reduce damage to other components during the disassembly process.

[0030] A fixing structure 6 is provided on the horn 3, and the blade 5 is fixed on the horn 3 through the fixing structure 6, achieving the effects of improving the cutting quality and facilitating the replacement of the blade 5. A groove 61 is opened at one end of the horn 3 close to the blade 5, and a clamping groove 62 adapted to the shape of the blade 5 is opened on the inner wall of the groove 61. The end of the blade 5 is clamped in the clamping groove 62. The blade 5 is positioned through the cooperation of the groove 61 and the clamping groove 62, and is locked on the horn 3 by using a screw 63 and a nut 64 to form a stable structure, thereby ensuring the accuracy and high efficiency of the cutting process. The fixing structure 6 includes a screw 63 arranged in the groove 61. The two ends of the screw 63 are respectively detachably connected to the inner wall of the groove 61. Two nuts 64 are arranged on the screw 63. A through hole 65 is arranged on the blade 5. The screw 63 passes through the through hole 65, and the blade 5 is fixed by tightening the nut 64. A wear-resistant material is coated at the joint where the surface of the blade 5 fits with the nut 64. Commonly used wear-resistant materials include polytetrafluoroethylene, tungsten carbide, etc., to prevent the nut 64 from wearing the blade 5.

[0031] Working principle: An instrument for cutting materials based on ultrasonic technology designed by the utility model enables the energy of ultrasonic waves to be efficiently transmitted to the blade 5 by designing a stable and reliable connection relationship among the ultrasonic transducer 2, the horn 3, and the drive power supply 4, thereby improving the cutting accuracy and efficiency of the materials. In addition, by optimizing the fixing structure 6 between the horn 3 and the blade 5, the installation of the blade 5 is made more convenient and fast, greatly reducing the operation difficulty and ensuring the stable position of the blade 5 during the cutting process.
