A shaft hole 331 is disposed at the center of the shaft core 31, and the shaft hole 331 is disposed at the center of the shaft core 31. A bearing 34 is disposed in the shaft hole 331 to be assembled with the upper end of the shaft core 31, and the bearing plate 33 is disposed on the side of the shaft hole 331 with an arcuate guide groove 332 for the guide rod 32 to pass through. In the arcuate guide groove 332, an elastic member 35 is further disposed on the carrier plate 33. The elastic member 35 can be a coil spring, and a blade assembly vertical plate 36 is disposed above the elastic member 35, and the blade assembly plate is assembled. 36 is provided with a locking fastener 361 for locking with the shaft core 31, and a plurality of locking members 361 are further disposed at the side of the center of the blade assembly vertical plate 36 to make the blade assembly plate 36 and the carrier plate 33 The interlocking member is further configured to set the elastic member 35-end to the blade assembly vertical plate 36, and further fix the elastic member 35 at the other end and a set of elastic members connected to the set hole 21 of the turntable 2. 37 is provided with the group, and then set on the side of the carrier plate 33 connected with opposite first link and the second link 38 fixed to the tip fixed to the tip 39;

The synchronizing link 4 is provided with a synchronizing link 4 in each group between the adjacent grouping units 3, so that the synchronizing link 4 is formed with a class 41 at an intermediate position so that the synchronizing link 4 has two ends. The first and second pivot holes 42 are disposed at one end of the synchronous link 4, and the first pivot of one end of the synchronous link 4 is formed. The hole 42 is assembled with the first link fixing leg 38 on the carrier plate 33 of the adjacent set of the standing unit 3 thereof, and the second pivot hole 43 at the other end of the synchronous link 4 is adjacently established.

Accordingly, when used, please refer to FIG. 4 and FIG. 5 to activate the rotary power source 12 of the spread fan body 1 to rotate the turntable 2 assembled with the rotary power source 12, at this time, via The blade 5, which is assembled with the unit 3 and pivotally connected to the turntable 2, will rotate with the centrifugal force generated by the rotation of the turntable 2, causing the blade 5 to be rotated outward, and when the blade 5 is thrown outwardly with the centrifugal force of the turntable 2, When opened, the blade assembly vertical plate 36 that is assembled will be driven to rotate together. When the blade assembly vertical plate 36 rotates, the coil spring-shaped elastic member 35 assembled at the blade assembly vertical plate 36 will be subjected to the blade assembly vertical plate. 36 is pulled into an open state, and at the same time, the carrier 33 locked with the blade assembly vertical plate 36 is also rotated along with the blade assembly vertical plate 36. At this time, the assembly is set in the adjacent assembly unit. The synchronization link 4 between the decks 33 of the three sets is arranged, so that when the carrier plates 33 of the set of the vertical units 3 are rotated, the carrier plates 33 of the adjacent other set of the vertical units 3 are synchronously driven to rotate, thereby utilizing the synchronization The traction of the connecting rod 4 can ensure that the blades 5 assembled on the blade group vertical plate 36 of each group of the vertical units 3 are synchronously deployed. Therefore, in order to maintain the stability of the fan movement, avoid the uneven speed of the blade 5, resulting in uneven wind and wind, and prevent the blade 5 from being unfolded at different speeds, causing the center of gravity to yaw and rotate.

The support plate 33, which is locked with the blade assembly vertical plate 36, is also rotated and reset with the reset of the blade assembly vertical plate 36, and is disposed between the support plates 33 of the adjacent assembly unit 3 at this time. The traction action of the synchronous link 4 can ensure that the blades 5 assembled on each group of the vertical units 3 are synchronously folded to avoid the center of gravity yaw caused by the different folding speed of the blades 5, resulting in the rotary power source 12, etc. Defects such as rapid damage to components and loud noises.

It is also worth mentioning that when the assembly unit 3 of the present invention rotates the carrier plate 33, the arcuate guide groove 332 is disposed on the carrier plate 33 and disposed on the curved guide groove 332, and the turntable 2 The mutual guiding between the assembled guide rods 32 can further improve the stability and stability of the tensioning action of the carrier plate 33 and the blade 5 assembled thereon, and when the carrier plate 33 rotates, the carrier plate 33, the assembly between the bearing 34 and the shaft core 31 of the central shaft hole 331 can be utilized, and the bearing 34 has high rolling and low friction characteristics to further increase the engagement between the carrier plate 33 and the blade 5 disposed thereon. The rapid and fluent time is achieved, and the initial wind power is increased, the power loss caused by friction is reduced, and the substantial frictional damage between the carrier plate 33 and the shaft core 31 is prevented, and the actual benefits such as rapid wear and tear are prevented.

The above is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Equivalent changes and modifications made by those skilled in the art without departing from the spirit and scope of the invention shall fall within the scope of the invention.
