A plurality of fixing holes 10 are equidistantly provided on the side wall of the annular ring 6, and a plurality of contact heads 9 are pressed in the fixing holes 10.

[0029] In this embodiment, when it is necessary to adjust the angle of multiple guide plates 2, first, the follower ring 5 is rotated. Since one end of the follower spring 4 is rotatably connected to the follower ring 5, and the other end of the follower spring 4 is fixedly connected to the rotating shaft 3, when the follower ring 5 rotates, the follower spring 4 can compensate for the elongation and drive the rotation of the rotating shaft 3. Therefore, the multiple guide plates 2 rotate with the angle. The effect of diversion and noise reduction can be controlled through different angles, and with the assistance of multiple through holes 20 and guide rods 21, the diversion effect can be adjusted according to the corresponding situation.

[0030] More specifically, when the follower ring 5 rotates, since the multiple contact heads 9 are pressed against the fixing hole 10, the rotated follower ring 5 can be positioned, thereby completing the positioning process. When it is necessary to change the fixing force of the contact head 9, it is only necessary to continue to press the insertion rod 101 inward so that the push spring 8 is in a compressed state. Due to the unidirectional movement of the multiple one-way sheets 11, the convenience of insertion adjustment can be guaranteed. When it is necessary to release, it is only necessary to rotate the round head 12 along the spiral groove 13 to release the connection between the two, thereby completing the entire process.

[0031] In summary, when the overall device is in use or running: when it is necessary to adjust the angle of multiple guide plates 2, first rotate the follower coil 5. Since one end of the follower spring 4 is rotatably connected to the follower coil 5, and the other end of the follower spring 4 is fixedly connected to the rotating shaft 3, when the follower coil 5 rotates, the follower spring 4 can compensate for the elongation and drive the rotation of the rotating shaft 3. Therefore, the multiple guide plates 2 rotate accordingly. The effect of diversion and noise reduction can be controlled through different angles, and with the assistance of multiple through holes 20 and guide rods 21, the diversion effect can be adjusted according to the corresponding situation.

[0032] When the follower ring 5 rotates, since the multiple contact heads 9 are pressed against the fixing hole 10, the rotated follower ring 5 can be positioned, thereby completing the positioning process. When it is necessary to change the fixing force of the contact head 9, it is only necessary to continue to press the insertion rod 101 inward to make the push spring 8 in a compressed state. Due to the unidirectional movement of the multiple one-way sheets 11, the convenience of insertion adjustment can be guaranteed. When it is necessary to release, it is only necessary to rotate the round head 12 along the spiral groove 13 to release the connection between the two, thereby completing the entire process.
