[0048] Working principle: Before using this device, first rotate the bidirectional threaded rod 3. Due to the effect of threaded connection, the moving block 4 starts to move, and the moving block 4 will drive the rotating plate 5 to rotate, which makes the position of the spoiler column 7 on the fixed block 6 adjusted. During this process, the position of the flexible plate 8 will also be driven to change due to the linkage of related components. In addition, the movement of the eddy current column 9 inside the spoiler column 7 can improve the fluidity of the fluid, which brings better conditions for the entire fluid flow process;

[0049] When the spoiler column 7 moves, the connecting rod 205 connected thereto will move accordingly.

At this time, the rotating rod 202 on the guide piece 203 will rotate along the reserved groove 201. Through such a series of linkages, during the movement of the spoiler column 7, the guide piece 203 can effectively adjust the flow direction of the fluid, so as to better control the flow state of the fluid.
