An annular set of connecting members 43 is disposed in the set of connecting spaces 42. The inner peripheral ring of the connecting member 43 is provided with a plurality of axially disposed plurality of teeth 431; a sleeve 50 is formed in a hollow cylindrical shape. And an open end 51 having an opening, the inner end of the open end 51 is continuously arranged with an axially disposed plurality of teeth 511, and the open end 51 is engaged with the assembled space 42 and the mandrel 41 is A sleeve 50 is provided; a driving assembly 60 includes two elastic members 61 and first and second ratchet rings 62 and 63. The two elastic members 61 are each a scroll spring, and the two elastic members 61 are respectively The first ratchet ring 62 and the second ratchet ring 63 are arranged in a continuous arrangement on the outer circumference of the hub body 40, and the first ratchet ring 62 and the second ratchet ring 63 are arranged in the outer circumference of the outer ring to be provided with the fitting teeth 621, 631. One end of the first ratchet ring 62 is radially continuously provided with a predetermined inclination of the engaging tooth portion 622, and one of the second ratchet rings 63 is terminated to face the engaging tooth 622 is oppositely provided with a meshing tooth portion 632. The first ratchet ring 62 is disposed in the assembly space 42 of the hub body 40, and the peripheral tooth fitting portion 621 and the plurality of teeth of the socket member 43 The second ratchet ring 63 is disposed inside the open end 51 of the sleeve 50, and the outer peripheral fitting teeth 631 are engaged with the plurality of teeth 511 to limit the first ratchet ring 62. And the second ratchet ring 63 is pressed against the corresponding elastic member 61. The first and second ratchet rings 62, 63 are pushed outward by the elastic member 61, and are engaged with each other through the engaging tooth portion 622 and the meshing tooth portion 632 to form a flower hub driving device.

With the above structure, when the flywheel drives the sleeve 50 to rotate in one direction, please refer to FIG. 8 at the same time, the sleeve 50 can tilt the meshing tooth portion 632 of the second ratchet ring 63 and the first ratchet ring. The card engaging portion 622 of the 62 is engaged, and the hub body 40 can be rotated; when the flywheel drives the sleeve 50 to rotate in the opposite direction, please refer to the first and second ratchet rings as shown in FIG. The engaging teeth portion 622 and the engaging tooth portion 632 of the 62 and 63 are mutually repelled and retracted, and simultaneously compress the elastic members 35 on the same side to separate the second ratchet ring 63 from the first ratchet ring 62. The sleeve 20 is then brought to an idling state.

It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reasons are as follows: (1) The conventional structure is provided with an elastic member 61 in the hub body 40 and the sleeve 50, and The two elastic members 61 are respectively elastically pushed against the first and second ratchet rings 62 and 63 to achieve the clutching state of the first and second ratchet rings 62 and 63, which not only causes complicated and inconvenient structural assembly, but also increases the manufacturing cost of the structure. On the one hand, since the two elastic members 61 are squeezed and contracted by the first and second ratchet gears 62 and 63, the first and second ratchet gears 62 and 63 are not in a reliable state, and the utility model is lacking in practicality.

(2) The two elastic members 61 are all a scroll spring, and the scroll spring forms a height difference at the end due to the formation of a spiral shape, so that the two elastic members 61 cannot be evenly abutted against the first and second ratchet rings 62, 63. On the surface, there is a concern that the elastic force is unevenly applied. When the two elastic members 61 are pushed against the first and second ratchet rings 62 and 63, the first and second ratchet rings 62 and 63 are easily unevenly applied. However, the occurrence of the skew displacement causes an inaccurate meshing state between the first and second ratchet rings 62, 63, resulting in slippage and detachment between the teeth, and an unstable resistance such as a card angle is formed. It accelerates the wear of the tooth and reduces the service life of the meshing linkage, which is a lack of structural use.
