The output shaft of the electric push rod 6 vertically passes through the top of the right-angle frame 2, and a motor box 7 is fixed to the bottom end of the output shaft of the electric push rod 6. That is, when the electric push rod 6 is running, it can drive the motor box 7 to move up and down, thereby controlling the lifting and lowering of the shearing head 3 to realize the feeding function of moving down into the material barrel 4 and moving up and out of the material barrel 4;

[0022] The rotating assembly includes a servo motor 8, the bottom of the servo motor 8 is fixed to the bottom of the inner wall of the motor box 7, the bottom end of the output shaft of the servo motor 8 vertically penetrates the bottom of the motor box 7, and a connecting plate 9 is horizontally fixed to the bottom end of the output shaft of the servo motor 8. Specifically, when the servo motor 8 is running, it can drive the connecting plate 9 to rotate forward and reverse, thereby driving the shearing head 3 to rotate forward and reverse in the barrel 4;

[0023] The lifting assembly includes a vertically arranged electric push rod 10, the bottom end of which is fixed to the top of the connecting plate 9 away from the servo motor 8, the bottom end of the output shaft of the electric push rod 10 vertically penetrates the connecting plate 9, and a motor box 11 is fixed to the bottom end of the output shaft of the electric push rod 10. Specifically, when the electric push rod 10 is running, the motor box 11 can be driven to move up and down, thereby driving the shear head 3 to move up and down in the barrel 4;

[0024] The driving assembly includes a motor 12, which is preferably configured as a variable frequency motor. The bottom of the motor 12 is fixed to the bottom of the inner wall of the motor box 11, and the bottom end of the output shaft of the motor 12 vertically penetrates the bottom of the motor box 11. A coupling 13 is vertically fixed to the bottom end of the output shaft of the motor 12, and the top of the shearing head 3 is fixed to the bottom end of the coupling 13.
