The output end of the actuator 8 drives the shaft 11 to rotate, and the shaft 11 rotates to drive the output shaft tie rod 9 to move. The output shaft tie rod 9 and the transmission frame 10 have multiple shaft hole matching points. The transmission frame 10 rotates and translates around the shaft 11, and drives the main blade 6 to rotate and translate around the shaft 11.
