The first part is located at the other end of the insert 3, and its end is connected to a conical top block 701. A first spring 8 is wound around the slide rod 7, with its two ends connected to the top block 701 and the top of the insert 3 respectively. A guide rod 5 is provided on the inner wall of the bottom of the insert 3. A wedge-shaped locking block 4 is slidably provided on the guide rod 5. The wedge-shaped locking block 4 can slide along the guide rod 5 and pass through one side of the insert 3. A tension spring 6 is wound around the guide rod 5. One end of the tension spring 6 is connected to the inner wall of the insert 3, and the other end is connected to the rear side of the wedge-shaped locking block 4. The fan 2 can be inserted into the mounting bracket 1 through the insert 3 and connected to the wedge-shaped locking block 4. The limit switch is attached to the mounting bracket 1. The contact surface between the wedge-shaped locking block 4 and the mounting bracket 1 is provided with an anti-slip pad 17. A rotating rod 9 is rotatably mounted at the upper center of the fan 2. Two centrally symmetrical spiral grooves are formed on the rotating rod 9. A sliding plate 10 is slidably mounted on the rotating rod 9.
