[0030] The above mechanism allows for the convenient support and rotation of the blade 2 via the connecting shaft 3. The movement of the control plate 5 facilitates the movement of the rack 8, which in turn drives the gear 4 to rotate. The rotation of the gear 4 drives the connecting shaft 3 to rotate, which in turn drives the blade 2 to rotate.

[0032] The pressure plate 9 is slidably connected to the front side of the control plate 5, and the unlocking rod 12 is rotatably connected to the front side of the pressure plate 9. The rear side of the unlocking rod 12 is rotatably connected to the front side of the insertion rod 13. When the pressure plate 9 moves, it will push the unlocking rod 12. When the unlocking rod 12 moves, it will push the insertion rod 13 to the right and disengage from the slot, thereby unlocking the control plate 5.

[0033] As a preferred embodiment of this utility model, a sliding sleeve 6 is fixedly connected to the left side of the control plate 5. The inner wall of the sliding sleeve 6 is slidably connected to the outer wall of the slide frame 7. The slide frame 7 can conveniently limit the sliding sleeve 6, so that the sliding sleeve 6, the control plate 5 and the rack 8 can move stably and vertically.

[0037] The working principle of this utility model is as follows: In actual use, when it is necessary to adjust the rotation angle of the blades 2 of the central air conditioning outlet 1, the pressure plate 9 is pushed first. At this time, the pressure plate 9 moves down and compresses the spring 11. At the same time, the movement of the pressure plate 9 pushes the unlocking rod 12. The movement of the unlocking rod 12 pushes the insertion rod 13 to the right and disengages it from the slot, thereby unlocking the control plate 5. Then, the control plate 5 is pushed up and down, which drives the two racks 8 to move up and down. The movement of the racks 8 drives the meshing gear 4 to rotate. The rotation of the gear 4 drives the connecting shaft 3 to rotate from... The blade 2 rotates, and during use, the gear 4 and rack 8 can be selected according to the usage requirements to control the rotation angle of the blade 2 each time. When the blade 2 rotates to the appropriate position, the pressure plate 9 is released. At this time, the spring 11 loses its restriction and pushes the pressure plate 9 to move upward and reset. At the same time, the reset of the pressure plate 9 will pull the unlocking rod 12 to move, causing the insertion rod 13 to move. At this time, the insertion rod 13 moves laterally and engages with the slot to fix the control plate 5, thereby fixing the blade 2 at the current angle, achieving the effect of adjusting the rotation angle of the blade 2 at the air outlet 1 according to the usage requirements.
