Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] The present invention provides a simple rotary two-way unlocking and self-locking structure, which includes an unlocking button 1, a first return spring 2, a transmission lever 3, a steel wire 4, a second return spring 5, a stop tooth disc 6, a tooth disc fixing shaft 7, and a fixing knob 8. The first return spring 2 is installed and connected in the exact middle of the lower end of the unlocking button 1. The transmission lever 3 is located below the unlocking button 1. The steel wire 4 is connected to one side of the transmission lever 3. The second return spring 5 is installed at the lower end of the steel wire 4. A locking tongue 9 is connected to the lower end of the second return spring 5. The lower end of the locking tongue 9 is connected to the stop tooth disc 6. The tooth disc fixing shaft 7 is installed and connected at the center of the stop tooth disc 6. The fixing knob 8 is installed and connected at the top of the tooth disc fixing shaft 7.

[0019] The transmission lever 3 includes a resistance lever 310, a fulcrum post 311, and a power lever 312. The resistance lever 310 and the power lever 312 are connected on both sides of the fulcrum post 311. The resistance lever 310 is located at the lower end of the unlocking button 1. One side of the power lever 312 is connected to the steel wire 4.

[0021] As Figure 1 , in this embodiment, a simple rotary two-way unlocking and self-locking structure is applied in a household fan and is installed at both ends inside the fan housing 10.

[0022] Working principle: As Figures 1-4 , when the unlocking button 1 is not pressed, the locking tongue 9 is inserted into the spines 610 of the stop tooth disc 6 and is in a locked state. When the unlocking button 1 is pressed, since the unlocking button 1 moves downward and presses the resistance lever 310 in the transmission lever 3 to move downward, driving the power lever 312 to move upward, thereby driving the steel wire 4 to move in the same direction, and at the same time driving the locking tongue 9 to leave the stop tooth disc 6, completing the unlocking function. At this time, the fan is rotated to the required position through the fixing knob 8. When the unlocking button 1 is pressed again and released, due to the simultaneous action of the first return spring 2 and the second return spring 5, the locking tongue 9 automatically resets to complete the positioning.
