The concrete principle of the invention is as follows
(1) According to the invention, the fan head body 2 is rotationally connected to the support 4 along the horizontal axis through the connecting piece 6, in addition, the limiting piece 8 which is cooperated with the fan head body 2 to rotate is arranged, and when the fan head body 2 rotates along the horizontal axis under the action of external force, the limiting piece 8 can move in the adjacent slot 12; when the fan head body 2 is stationary, the limiting member 8 is limited in one of the slots 12, so as to limit the rotation of the fan head body 2 around the horizontal axis under the action of gravity, thereby playing a role in fixing the fan head body 2 after rotation. The limiting member 8 is located in the sliding slot of the rotating shaft 14, the free end of the limiting member 8 abuts against the contour surface of the slot 12 under the action of the spring, and the condition that the free end of the limiting member 8 slides on the contour surface of the slot 12 is that the torque transmitted to the limiting member 8 by the fan head body 2 can overcome the compression force of the spring to jack up the limiting member 8 upwards so as to ensure the height matched with the contour surface on the one hand, and on the other hand, the friction force between the free end and the contour surface needs to be overcome so as to ensure the relative sliding. Obviously, when no external force acts, the motion condition of the limiting member 8 cannot be satisfied only by gravity, and thus, at this time, the fan head body 2 can be locked by the limiting member 8; when the fan head body 2 needs to be rotated, the above-mentioned motion conditions can be achieved by manpower, and at this time, the torque acting on the limiting member 8 can push the limiting member 8 to move from one slot 12 to another adjacent slot 12 against the elastic force of the spring and the friction force of the contour surface of the slot 12. The auxiliary connecting shaft 20 is arranged, so that the fan head body 2 can be connected to the support 4 in a more stable rotating mode. The purpose of the rotating handle 22 is to facilitate the rotation of the fan head body 2 by human power.
(2) In the fan, the upright post 24 can rotate and lift, so that the height of the air outlet can be adjusted, and the air outlet can be swung.
