[0034] The reel 300e may have a disk structure and include a first opening 321e, a second opening (not shown), an inclined surface 316e, and a bottom hole 315e, where the first opening 321e and the second opening communicate with the bottom hole 315e. The first and second ends of the linear object T1 can be coupled to the reel 300e through the first and second openings, respectively, and the linear object T1 is wound around the central pillar of the reel 300e. In detail, the first end of the linear object T1 can penetrate from the first opening 321e toward the inclined surface 316e and then be exposed to the lower opening 240e through the bottom hole 315e, and the second end can penetrate through the second opening toward the inclined surface 316e and then be exposed to the lower opening 240e through the bottom hole 315e, and the user can tie it, thus preventing the linear object T1 from detaching from the first opening 321e and the second opening, and then the base 270e can be assembled to the housing 260e.

[0035] The knob 500e may include a rotating cover 530e and an internal disk 510e, and the internal disk 510e is coupled to the rotating cover 530e. The brake unit 400e is coupled to the knob 500e and the reel 300e, the ratchet ring 800e is provided in the housing 260e, and the spring 700e is located on the ratchet ring 800e and seated on the internal disk 510e.

[0036] More specifically, the ratchet ring 800e includes a plurality of lower diagonal teeth 810e, a plurality of upper diagonal teeth 820e, and a plurality of ratchet ring teeth 830e, the lower diagonal teeth 810e and the upper diagonal teeth 820e are both located on the outer surface of the ratchet ring 800e, the lower diagonal teeth 810e are located below the upper diagonal teeth 820e to correspond to the internal teeth 230e, and the ratchet ring teeth 830e are located on the inner surface of the ratchet ring 800e.

[0037] The brake unit 400e is located within the ratchet ring 800e and includes a brake ring 410e, an inner ring 450e, a plurality of engagement teeth 460e, and three ratchet arms 470e. The inner ring 450e is located within the brake ring 410e, is axially displaceable relative to the brake ring 410e, and includes a threaded hole 451e. The engagement teeth 460e are located on the inner ring 450e and can be detachably engaged with the engagement teeth 330e, and the three ratchet arms 470e are provided on the brake ring 410e and correspond to the ratchet ring teeth 830e.

[0038] The knob 500e may further include a guide inclined block 520e located on the inner wall of the rotating cover 530e and corresponding to the upper inclined tooth 820e, and the inner disk 510e may further include a stud bolt 511e and an engagement arm 512e, where the stud bolt 511e is screwed into the corresponding screw hole 451e, and the engagement arm 512e is selectively coupled to the engagement protrusion 411e of the brake ring 410e.

[0039] With this structural arrangement, when the rotating cover 530e rotates in the tightening direction, the ratchet arm 470e and the ratchet ring teeth 830e repeatedly separate, allowing the reel 300e to tighten the linear object T1. Conversely, when the rotating cover 530e rotates in the loosening direction without being pressed, the inner ring 450e is driven by the stud bolt 511e to rise relative to the brake ring 410e. In this case, the inner ring 450e separates from the engaging teeth 330e, allowing the reel 300e to rotate freely without being constrained and loosen the linear object T1. When the rotating cover 530e rotates in the loosening direction and is pressed, the upper diagonal teeth 820e are guided by the guide inclined block 520e, causing the ratchet ring 800e to move upward, separating the lower diagonal teeth 810e from the internal teeth 230e, and further gradually loosening the linear object T1.

[0040] The knob 500e may also include a fitting portion 540e corresponding to the engagement portion 250e of the housing 200e, the details of which are the same as the fitting portion 540c and engagement portion 250c of the first embodiment shown in Figures 1 to 5, and therefore a duplicated description will be omitted here.

[0041] <Fourth Example> See Fig. 10 which is an exploded view showing a fastening device 100f according to a fourth embodiment of the present invention, Fig. 11 which is another exploded view showing the fastening device 100f of the fourth embodiment of Fig. 10, and Fig. 12 which is a side cross-sectional view showing the fastening device 100f of the fourth embodiment of Fig. 10.

[0042] When the knob 500f is rotated in the tightening direction relative to the housing 200f, the ratchet ring 800f repeatedly moves up and separates from the internal teeth 230f, allowing the reel 300f to rotate in the tightening direction and tighten the linear object. When the knob 500f is pressed and rotated in the loosening direction relative to the housing 200f, the reel 300f can rotate in the loosening direction to gradually loosen the linear object. This shows that the ratchet ring 800f can block or loosen the reel 300f as a braking unit in the fourth embodiment.

[0043] <Fifth Example> Please refer to Fig. 13 which is an exploded view showing a fastening device 100g according to a fifth embodiment of the present invention, Fig. 14 which is another exploded view showing the fastening device 100g of the fifth embodiment of Fig. 13, and Fig. 15 which is a side cross-sectional view showing the fastening device 100g of the fifth embodiment of Fig. 13.

The ratchet ring 800g includes three first arms 810g, three second arms 820g, and a plurality of ratchet ring teeth 830g. The first arms correspond to the internal teeth 230g of the housing 260g, and the second arms 820g simultaneously correspond to the internal teeth 230g and the top teeth 520g. The ratchet arms 470g of the brake unit 400g are selectively engaged with the ratchet ring teeth 830g.

[0045] When the knob 500g is biased in the tightening direction, the second arm 820g and the top tooth 520g separate to allow the knob 500g to rotate in the tightening direction, and thus the brake ring 410g is driven by the knob 500g to separate the ratchet arm 470g and the ratchet ring tooth 830g.

[0046] When the knob 500g is biased in the loosening direction, the inner ring 450g rises under the influence of the structure of the stud bolt 510g and the screw hole 451g and separates from the reel 300g.
