On the basis of the structure, when the swing direction of the fan blade 130 needs to be adjusted, the first transmission tooth part 532 and the second transmission tooth part 541 are fixed by the limiting structure 56, at this time, the rotating motor drives the second transmission gear 55 to rotate, and the power of the second transmission gear 55 is transmitted to the transmission shaft 40 through the second transmission tooth part 541 of the adjusting rod 54, the first transmission tooth part 532 of the first transmission gear 53, the umbrella tooth part 531 of the first transmission gear 53 and the bevel gear 52 in sequence, so that the transmission shaft 40 is driven to rotate; when the second transmission gear 55 and the adjustment lever 54 are unlocked, the adjustment lever 54 does not rotate with the second transmission gear 55, that is, the orientation of the fan blade 130 is not adjusted, so that the direction of the fan blade 130 can be selectively adjusted.
It should be mentioned that the bevel gear 52, the first transmission gear 53, the adjusting rod 54, the second transmission gear 55 and the limiting structure 56 are all disposed in the box 51, so that the space inside the box 51 can be reasonably utilized by matching different components, thereby further reducing the overall volume.

The limit structure 56 may be a fixing bolt, and the fixing bolt passes through the adjusting rod 54 and the second transmission gear 55, but the fixing bolt is easily lost after the fixing bolt is pulled out; therefore, the following embodiments are preferred for the limiting structure 56 in this embodiment: as shown in fig. 4-5, the adjusting rod 54 is also axially movable relative to the second transmission gear 55; the limiting structure 56 comprises a pressing spring 561, a limiting block 562 and a limiting groove 563 which is formed by the inner wall of the second transmission gear 55 sinking towards the direction far away from the central axis; the limiting block 562 is mounted on the adjusting rod 54 through the pressing spring 561; when the adjusting rod 54 moves along the axial direction, the adjusting rod can be linked with the limiting block 562 to be inserted into or separated from the limiting groove 563; when the limiting block 562 is inserted into the limiting groove 563, the pressing spring 561 is compressed to provide an elastic stress for urging the limiting block 562 to abut against the bottom of the limiting groove 563, and at this time, the second transmission gear 55 can drive the adjusting rod 54 to rotate when rotating; when the limit block 562 is separated from the limit groove 563, the limit block 562 can be linked to the upper side of the second transmission gear 55, and at this time, the pressing spring 561 is restored, so that the distance between the limit block 562 and the central axis of the second transmission gear 55 is greater than the inner radius of the second transmission gear 55, and the adjusting rod 54 can be prevented from moving downward.
It should be noted that, when the adjusting lever 54 is moved, the inner wall of the second transmission gear 55 abuts against the limiting block 562 under the action of the external force, so that the abutting spring 561 is deformed, and the adjusting lever 54 can be moved smoothly.
In order to further improve the relative stability of the second transmission gear 55 and the adjusting rod 54, preferably, two limiting grooves 563 are formed in the inner wall of the second transmission gear 55; two ends of the pressing spring 561 are respectively fixed with two limit blocks 562; the two limit blocks 562 are used for corresponding to the two limit grooves 563 one to one.

Further, the rotating shaft 70 is installed on the U-shaped frame body 21 through the limiting rod 90, the diameter of the limiting rod 90 is larger than that of the through hole 80, and at this time, after the rotating shaft 70 passes through the installation through hole 80, the limiting rod 90 can abut against the inner wall of the U-shaped frame body 21 to prevent the rotating shaft 70 on one side from excessively extending out of the through hole 80, so that the rotating shaft 70 on the other side is separated from the corresponding through hole 80.
Specifically, the inner side surface of the U-shaped frame body 21 is formed into a first limiting surface around the circumferential portion of the through hole 80, the surface of the limiting rod 90 facing the through hole 80 is formed into a second limiting surface, and the second limiting surface can be abutted against the first limiting surface; the shaft 70 is mounted on the second limiting surface.
More specifically, the rotating shaft 70 and the stopper rod 90 are coaxially disposed.
Further, the support 10 extends upward to form a cylindrical insertion column 100, and an insertion column 110 is arranged in the cylindrical insertion column 100; the support rod 22 is provided with a jack 160; the supporting rod 22 is inserted into the cylindrical inserting column 100 in a matching manner, namely, a gap between the outer wall of the supporting rod 22 and the inner wall of the cylindrical inserting column 100 is very small, so that the cylindrical inserting column 100 can limit the supporting rod 22 to swing in the rotating process of the supporting rod 22; the insertion hole 160 is sleeved outside the insertion column 110 in a matching manner, that is, a gap between a hole wall of the insertion hole 160 of the support rod 22 and an outer wall of the insertion column 110 is very small, so that the insertion column 110 can limit the support rod 22 from shaking during the rotation of the support rod 22; thus, the double limitation of the strut 22 is realized, and the stability of the rotation of the strut 22 is improved.
Specifically, the second rotating bracket 30 includes a cylindrical bracket body, and a first screw mounting hole 31 is formed at the bottom of the cylindrical bracket body; the wall of the cylindrical frame body extends outwards to form a mounting wall 32, and the mounting wall 32 is provided with a second screw mounting hole 33; in this way, the fan blade 130 and the case 51 can be coupled to the cylindrical frame body through the first screw mounting holes 31 and the second screw mounting holes 33, respectively.

Specifically, the shaped double torsion spring 120 starts to release force during the upward rotation of the second rotating bracket 30, and the shaped double torsion spring 120 gradually accumulates energy during the downward rotation of the second rotating bracket 30.
