The shaft seat 200 is disposed inside the other end of the outer tube 100, and the shaft seat 200 is disposed along the central axis of the outer tube 100.

Referring to FIG. 3 to FIG. 8 , the blades 300 are arranged radially around the shaft base 200 . The two ends of each blade 300 are an inner end 301 and an outer end 302 opposite to the inner end 301 , and the two ends of the blade 300 . A rotating shaft 311 / 312 is respectively protruded from the upper portion, and the two rotating shafts 311 / 312 respectively pivotally connect the shaft seat 200 and the pipe body, thereby enabling the blade 300 to rotate between the shaft seat 200 and the pipe body, and the blades 300 When closed, each of the blades 300 overlaps another adjacent blade 300. In this embodiment, each of the blades 300 is respectively provided with a shaft 310. The two ends of the shaft 310 protrude from the two ends of the blade 300 to form the rotating shafts 311/312, but the present invention is not limited thereto. An edge of the outer end 302 of each blade 300 projects from a top pin 320, and the top pin 320 is spaced from the axis of rotation 312 on the outer end 302.

Each of the top pins 320 penetrates into the corresponding groove 110 and abuts the spring 410 in the groove 110 to interlock with the spring 410.

In the present example, the variable angle vortex generating device of the present invention is disposed in an intake passage of an engine, and the outer tube 100 is bored in the intake passage and is fixed to the inner wall of the intake passage. Referring to FIGS. 3 through 5, when the airflow passes through the variable angle vortex generating device of the present invention, the airflow flows through the blade 300 to form a vortex, and the airflow pushes the blade 300 to rotate the blade 300 open, thereby enabling the blade 300 to correspond differently. The airflow rate changes its angle of attack with respect to the airflow. When the airflow velocity is high, the angle of attack of the blade 300 with respect to the airflow is small, thereby reducing the resistance of the flow field; referring to FIG. 6 to FIG. 8, when the airflow velocity is low, the spring 410 pushes the top pin 320 to rotate the blade 300, and the blade is increased. The angle of attack of 300 relative to the airflow thus increases the flow path of the airflow within the flow passage to increase engine torque.
