[0040] A second electromagnet 19 is embedded in one side of the limiting plate 11, and the slider 13 is made of metal material that can be attracted by magnetism.

[0041] The positioning assembly 8 includes N third electromagnets 20 embedded in the inner wall of the shell 10 along the circumferential direction and a tube body 21 arranged on one side of the frame 1, a bolt 22 is passed through one side of the tube body 21 through a bearing, a conductive magnetic part 23 is fixed to the outer side of the bolt 22, and N conductive metal parts 24 are fixed to the inner wall of the tube body 21 through a spring hinge, and N is a positive integer.

[0042] The N conductive metal members 24 are electrically connected to the positive electrodes of the N third electromagnets 20 , respectively.

[0043] The trigger assembly 6 includes a cylinder 25, a push switch 26 and an elastic telescopic rod 27. The cylinder 25 is connected to the outer wall of the frame 1, and one end of the inner side of the cylinder 25 is connected to the elastic telescopic rod 27 through the push switch 26. The other end of the elastic telescopic rod 27 is connected to a squeezing plate 28. The open end of the cylinder 25 is an inclined structure arranged toward the inner side of the cylinder 25.

[0044] A controller 29 is connected to the outer side of the frame 1 , the negative poles of the N third electromagnets 20 are electrically connected to the controller 29 , and the conductive magnetic member 23 , the first electromagnet 16 , and the second electromagnet 19 are all electrically connected to the controller 29 .

[0045] The working principle and use process of the present invention:

[0046] In the first embodiment, in the initial state, the controller 29 controls the second electromagnet 19 to open, attract the slider 13, fix the slider 13, and firmly fix the closing of the rotating plate 2 through the rotating shaft 3, and the spring is in a compressed state at this time;

[0047] When the fan is opened and passes through the frame 1, the cylinder 25 is arranged on the inner upper side wall of the cylinder 25. The gas passing through the frame 1 can squeeze the squeezing plate 28 through the cylinder 25, so that the elastic telescopic rod 27 is deformed and the squeezing switch is triggered at the same time. As the airflow continues to flow, the press switch 26 is always pressed, so that the press switch 26 is opened. The pressing of the press switch 26 triggers the generation of an electrical signal which is transmitted to the controller 29. The controller 29 opens the first electromagnet 16 and closes the second electromagnet 19. The second electromagnet 19 no longer attracts the slider 13, and the first electromagnet 16 generates a magnetic The field generates a repulsive force on the permanent magnet 18, so that the permanent magnet 18 slides outside the sliding column 17. In specific implementation, the sliding column 17 can be set to be multiple, so that the electromagnet can be stably lifted and slid, and the traction rope 15 is pulled downward by the permanent magnet 18, and then the slider 13 is pulled to rotate, and then the rotating plate 2 is driven to rotate to a horizontal position through the rotating shaft 3, and the gravity of the pendulum 4 is overcome at the same time, and the slider 13 and the first electromagnet 16 are offset. Due to the open state of the first electromagnet 16, the slider 13 is fixed on the first electromagnet 16, so that the rotating plate 2 is stably rotated, opened and fixed, and the shaking of the rotating plate 2 is avoided;

[0048] After the fan is turned off and the wind stops, the wind stops squeezing the elastic telescopic rod 27, and then stops squeezing the press switch 26. The generated electrical signal is transmitted to the controller 29. The controller 29 controls the closing of the first electromagnet 16 and the opening of the second electromagnet 19, so that the first electromagnet 16 and the second electromagnet 19 return to their initial states. The first electromagnet 16 no longer attracts the slider 13 and no longer produces a repulsive force on the permanent magnet 18. The slider 13 is rotated by the gravity of the pendulum 4 and the attraction of the second electromagnet 19, and is attracted and fixed by the second electromagnet 19. In this process, the elastic force of the spring is overcome by the permanent magnet 18, and the slider 13 is reset by the traction rope 15 to cache and reduce the noise and vibration generated when the slider 13 is reset.

[0049] Embodiment 2, when in use, when it is necessary to additionally adjust the final rotation angle of the rotating plate 2, the bolt 22 is rotated, the two ends of the tube body 21 are blocked, a scale can be set at one end of the tube body 21, a pointer is set on the bolt 22, the pointer can point to the scale, and the bolt 22 is rotated to drive the conductive magnetic part 23 and one of the conductive metal parts 24 to collide and attract each other. When not rotating, the conductive magnetic part 23 and the conductive metal part 24 are not attracted. When the conductive magnetic part 23 and any one of the conductive metal parts 24 are attracted, the representative pointer points to a scale on the scale, which is convenient for identifying which conductive metal part 24 the conductive magnetic part 23 is attracted to. Through the action of the spring hinge, the conductive magnetic part 23 can rotate through different conductive metal parts 24. Since the N conductive metal parts 24 are respectively electrically connected to the positive poles of the N third electromagnets 20, and the negative poles of the N third electromagnets 20 are electrically connected to the controller 29, the controller 29 and the conductive metal parts 24 are electrically connected to each other. The electromagnetic part 23 is electrically connected. When the controller 29 energizes the conductive magnetic part 23, when the conductive magnetic part 23 and any one of the conductive metal parts 24 are attracted, any one of the third electromagnets 20 is energized to open. Then, after the conductive magnetic part 23 and any one of the conductive metal parts 24 are attracted, when the fan is turned on, the first electromagnet 16 opens and closes the second electromagnet 19, and the conductive magnetic part 23 is energized at the same time to open the corresponding third electromagnet 20. By opening the first electromagnet 16, the traction rope 15 will attract the opened third electromagnet 20 during the process of pulling the slider 13, so that the slider 13 is fixed on the corresponding third electromagnet 20, and the rotating plate 2 is fixed at a fixed angle through the rotating shaft 3, so as to facilitate the adjustment of the size of the wind passing through the frame 1. When the fan stops, when the push switch 26 is not pressed, the power supply to the third electromagnet 20 is automatically canceled through the controller 29, so that the rotating plate 2 restores the closed frame 1.
