The plurality of planetary gears 253a are located in the storage space and correspond to the plurality of inner ring teeth 231a. The coupling member 240a is located in the storage space and can be selectively rotationally restrained with the gear 230a. The knob 210a covers the housing 300a and is operably coupled to the plurality of planetary gears 253a. The rotating member 400a is located in the storage space and is operably coupled to the rotary drive mechanism 200a. When the knob 210a rotates in the tightening direction R1 and the aforementioned multiple planetary gears 253a and the gear member 230a rotate in the tightening direction R1, the rotating member 400a rotates in the tightening direction R1 at a first speed; when the knob 210a rotates in the tightening direction R1 and the aforementioned multiple planetary gears 253a rotate relative to the gear member 230a, the rotating member 400a rotates in the tightening direction R1 at a second speed, and the second speed is different from the first speed.

The coupling portion 241a has a resilient arm structure and is disposed on the outer circumference of the coupling ring 242a and may extend along the circumference of the coupling ring 242a.

[0138] The gear member 230a may further include a plurality of protruding teeth 232a, and the coupling portion 241a may selectively couple to at least one of the protruding teeth 232a. Therefore, when the coupling portion 241a is coupled to at least one of the protruding teeth 232a, rotating the knob 210a in the tightening direction R1 drives the coupling portion 240a, thereby causing the gear member 230a to rotate in conjunction. In other words, when the coupling portion 241a engages with the protruding teeth 232a in the tightening direction R1, the coupling portion 241a drives the gear member 230a to rotate, causing the planetary gear 253a to rotate along with the gear member 230a. Conversely, when the coupling portion 240a is disengaged from the gear member 230a, the coupling portion 241a rotates without driving the gear member 230a, allowing the planetary gear 253a to rotate relative to the gear member 230a.

[0139] As shown in Figure 3, the gear member 230a may include a cylindrical wall 233a, with an inner ring tooth 231a disposed within the cylindrical wall 233a. The protruding teeth 232a are disposed within the cylindrical wall 233a and are located above the inner ring teeth 231a. The radial distance between two opposing protruding teeth 232a is smaller than the radial distance between two opposing inner ring teeth 231a. Thus, when the coupling member 240a is positioned within the cylindrical wall 233a of the gear member 230a, it may correspond to the protruding teeth 232a, while the planetary gears 253a may be located below the coupling member 240a and correspond to the inner ring teeth 231a. It should be noted that in this embodiment, although the detent member 220a and the gear member 230a are referred to separately, when the two are connected as a single unit, they can be considered to be a single unit comprising the ratchet arm 222a, the protruding teeth 232a, and the inner ring teeth 231a. In other embodiments, the detent member and the gear member may be separate components, without limitation.

[0140] The rotary drive mechanism 200a may further include a transmission assembly 250a, which may be driven by the knob 210a and include four planetary gears 253a. The four planetary gears 253a may be pivotally mounted on the rotating member 400a, so that rotating the knob 210a in the tightening direction R1 may drive the rotating member 400a.

[0141] The transmission assembly 250a may further include a transmission gear 255a and a sun gear 252a. The transmission gear 255a is connected to the knob 210a and rotates in conjunction with the coupling 240a. The sun gear 252a is meshed with the transmission gear 255a and the planetary gears 253a.

[0142] As shown in FIG3 , the transmission gear 255a can be integrally connected to the inner boss (not shown) of the knob 210a. The transmission gear 255a includes a plurality of internal teeth (not shown) and a plurality of external teeth (not shown). The sun gear 252a extends into the transmission gear 255a to engage with the internal teeth. The transmission gear 255a can be inserted into the coupling hole of the coupling member 240a, so that the external teeth engage with the coupling member 240a. This allows the knob 210a to rotate in conjunction with the transmission gear 255a and the coupling member 240a. The transmission assembly 250a can further include a support plate 251a and a stop ring 254a. The support plate 251a can be disposed between the planetary gears 253a and the coupling member 240a, and the stop ring 254a can be mounted on the lower end of the sun gear 252a.

[0143] Rotating member 400a is located below gear member 230a and may have a wire reel structure. Rotating member 400a may include a hollow body 430a, an upper ring portion 410a, and a lower ring portion 420a. Hollow body 430a includes an inner circumferential wall (not shown) surrounding a through-space (not shown). Upper ring portion 410a is disposed at one end of hollow body 430a, while lower ring portion 420a is disposed at the other end of hollow body 430a. This forms a winding track 440a between upper ring portion 410a and lower ring portion 420a, upon which a wire is wound. Upper ring portion 410a may include four pivots (not shown) and recesses (not shown). The four planetary gears 253a may be pivoted on the four pivots, respectively, and a stop ring 254a may be placed in the recess. This prevents sun gear 252a from directly interlocking with rotating member 400a.

[0144] The rotating member 400a may further include a flexible latching portion 450a, which protrudes from the inner peripheral wall toward the through-space. In the first embodiment, the number of the flexible latching portions 450a may be two and symmetrically arranged. The flexible latching portions 450a can be radially deformed by an external force and can be reset after the external force is removed.

[0145] Please refer to Figures 4, 5, 6, and 7, together with Figures 2 and 3, wherein Figure 4 is a side cross-sectional schematic diagram of the tie-wire fastening device 100a of the first embodiment of Figure 1, Figure 5 is another side cross-sectional schematic diagram of the tie-wire fastening device 100a of the first embodiment of Figure 1, Figure 6 is a top cross-sectional schematic diagram of the tie-wire fastening device 100a of the first embodiment of Figure 4 along the cut plane line 6-6, and Figure 7 is a top cross-sectional schematic diagram of the tie-wire fastening device 100a of the first embodiment of Figure 4 along the cut plane line 7-7. The tie-wire fastening device 100a may further include a connecting unit (not shown) that connects the knob 210a and the rotating member 400a.

[0146] Specifically, the connecting unit may include a positioning shaft 510a coupled to the flexible clamping portion 450a. When the knob 210a is pulled up along the axis X1 of the tie line fastening device 100a, the positioning shaft 510a can be moved from one side of the flexible clamping portion 450a to the other side to allow the rotating member 400a to rotate freely to release the tie line.

[0147] The connection unit may further include a screw (not shown). The positioning shaft 510a can be inserted from bottom to top into the through-space of the rotating member 400a to couple with the flexible latch 450a. The positioning shaft 510a can also pass through the sun gear 252a and enter the inner boss of the knob 210a. The screw then passes from top to bottom through the knob 210a and locks into the positioning shaft 510a. In this way, the knob 210a and the rotating member 400a are connected.

[0148] As shown in Figures 4, 6, and 7, the knob 210a is not yet pulled up and is in the first position. The ratchet arm 222a of the detent member 220a engages with the engaging teeth 312a, and the coupling portion 241a engages with the protruding teeth 232a. When the user grips the knob 210a and rotates it in the tightening direction R1, the sun gear 252a, driven by the transmission gear 255a, rotates in the tightening direction R1. Simultaneously, due to the friction between the coupling portion 241a and the protruding teeth 232a, the transmission gear 255a drives the coupling member 240a to rotate, thereby driving the gear member 230a. This prevents the planetary gear 253a from pivoting relative to the gear member 230a. Instead, the planetary gear 253a can rotate simultaneously with the sun gear 252a and the gear member 230a about the axis X1, thereby driving the rotating member 400a in the tightening direction R1. At this time, the knob 210a rotates 360 degrees in the tightening direction R1, and the rotating member 400a rotates at the first speed, so that the rotating member 400a can rotate 360 ​​degrees in the tightening direction R1 and tighten the tie line.

[0149] The tension in the tether line acts on the gear member 230a, attempting to rotate the gear member 230a in the release direction R2. The greater the tether line tension, the greater the load on the coupling member 240a. Therefore, when the tether line tension is excessive, causing the load on the coupling member 240a to be greater than or equal to a threshold, continued rotation of the knob 210a in the tightening direction R1 will cause the coupling portion 241a to disengage from the protruding teeth 232a, preventing the gear member 230a from rotating. Consequently, the gear member 230a becomes fixed. Because the gear member 230a is fixed, when the sun gear 252a rotates the planetary gears 253a, each planetary gear 253a can pivot relative to the gear member 230a and simultaneously rotate about the axis X1, driving the rotating member 400a. At this time, the knob 210a rotates 360 degrees in the tightening direction R1, and the rotating member 400a rotates at the second speed, so that the rotating member 400a can rotate 144 degrees in the tightening direction R1 and tighten the tie line.

[0150] In other words, when the line tension is low, the load on the coupling 240a is also low. Therefore, the gear 230a can be driven by the coupling 240a to rotate in the tightening direction R1. Therefore, turning the knob 210a can quickly tighten the line. Conversely, when the line tension increases, the load on the coupling 240a also increases. Therefore, the gear 230a cannot be driven by the coupling 240a to rotate in the tightening direction R1. Therefore, turning the knob 210a can slowly tighten the line. This achieves the effect of automatically adjusting the speed of the rotating element 400a.

[0151] When the knob 210a stops rotating in the tightening direction R1 and the cinch cord is tightened, the cinch cord tension causes the rotatable member 400a to be pulled in the release direction R2. Consequently, the sun gear 252a attempts to rotate the transmission gear 255a and the planetary gears 253a in the release direction R2. Due to the structural relationship between the coupling portion 241a and the protruding teeth 232a, the coupling member 240a engages with the gear member 230a in the release direction R2, and the gear member 230a is also pulled in the release direction R2 by the coupling member 240a. However, at this time, the distal end of the ratchet arm 222a engages with the engaging teeth 312a of the housing 310a, thereby preventing the rotatable member 400a from rotating in the release direction R2 and securing the cinch cord.

[0152] As shown in FIG5 , the knob 210a can be pulled up to the second position along the axis X1. At this time, the transmission gear 255a is linked to rise and separate from the sun gear 252a. The rotating member 400a is not restricted and can rotate in the release direction R2 to release the line.

[0153] Please refer to Figures 8, 9, and 10, wherein Figure 8 is a perspective view of a tie-line fastening device 100b according to a second embodiment of the present invention, Figure 9 is an exploded view of the tie-line fastening device 100b of the second embodiment of Figure 8, and Figure 10 is another exploded view of the tie-line fastening device 100b of the second embodiment of Figure 8. The structure of the tie-line fastening device 100b is similar to that of the tie-line fastening device 100a of the first embodiment and includes a rotation drive mechanism 200b (shown in Figure 11) and a rotating member 400b.

[0154] The rotation drive mechanism 200b is used to drive the rotating member 400b to rotate and includes a gear member 230b, a plurality of planetary gears 253b, a coupling portion 241b, and a knob 210b. The planetary gears 253b are located within the gear member 230b and mesh with each other. The coupling portion 241b can selectively engage with the gear member 230b. The knob 210b is operatively coupled to the plurality of planetary gears 253b. When the knob 210b is rotated in the tightening direction R1 and the coupling portion 241b engages and drives the gear 230b, the plurality of planetary gears 253b rotate together with the gear 230b in the tightening direction R1, causing the rotating member 400b to rotate in the tightening direction R1 at a first speed. When the knob 210b is rotated in the tightening direction R1 and the coupling portion 241b disengages from the gear 230b, the plurality of planetary gears 253b rotate relative to the gear 230b, causing the rotating member 400b to rotate in the tightening direction R1 at a second speed that is different from the first speed. Pulling the knob 210b releases the tie line.

[0155] Please refer to Figures 11 and 12, together with Figures 9 and 10, wherein Figure 11 is a side cross-sectional schematic diagram of the second embodiment of the tether securing device 100b of Figure 8, and Figure 12 is another side cross-sectional schematic diagram of the second embodiment of the tether securing device 100b of Figure 8. The tether securing device 100b may further include a housing 300b, the knob 210b of the rotary drive mechanism 200b may be covered by the housing 300b, and the other components and the rotating member 400b may be accommodated within the housing 300b.

[0156] As shown in Figures 9 to 11 , the second embodiment differs from the first embodiment in that the detent member 220b and the gear member 230b of the rotation drive mechanism 200b are two separate components. The detent member 220b may include a plurality of grooves 223b at its lower end, and the gear member 230b may include a plurality of upper latching protrusions 234b , each of which engages with a corresponding groove 223b to limit the rotation of the detent member 220b and the gear member 230b. Other similar details are not further described.

[0157] As shown in Figures 11 and 12, when the knob 210b is in the first position, it can rotate in conjunction with the coupling 240b. When the knob 210b is raised to the second position, it can still rotate in conjunction with the coupling 240b. The knob 210b does not restrict the rotation of the rotating member 400b, so the rotating member 400b can rotate freely. In this way, the tether line can be released by pulling it up.

[0158] Please refer to Figures 13, 14, and 15. Figure 13 is a perspective view of a driving device 100c according to a third embodiment of the present invention. Figure 14 is an exploded view of the driving device 100c of the third embodiment of Figure 13. Figure 15 is another exploded view of the driving device 100c of the third embodiment of Figure 13. The driving device 100c includes a rotation driving mechanism 200c (shown in Figure 16) and a rotating member 400c.

[0159] The rotation drive mechanism 200c is similar to the rotation drive mechanism 200a of the first embodiment. It is used to drive the rotation member 400c and includes a gear member 230c, a plurality of planetary gears 253c, a coupling portion 241c, and a knob 210c. The gear member 230c includes a plurality of protruding teeth 232c and a plurality of inner ring teeth 231c. The inner ring teeth 231c are located to one side of the protruding teeth 232c along the axis X1. The planetary gears 253c are located within the gear member 230c and correspond to the inner ring teeth 231c. The coupling portion 241c is located within the gear member 230c and corresponds to the protruding teeth 232c. The knob 210c is operably coupled to the plurality of planetary gears 253c. When the knob 210c rotates in the tightening direction R1 and the coupling portion 241c engages with the protruding tooth 232c and drives the gear member 230c, the aforementioned multiple planetary gears 253c and the gear member 230c rotate in the tightening direction R1, causing the rotating member 400c to rotate in the tightening direction R1 at a first speed; when the coupling portion 241c is affected by the rotating member 400c and disengages from the gear member 230c in the tightening direction R1, the knob 210c rotates in the tightening direction R1, causing the aforementioned multiple planetary gears 253c to rotate relative to the gear member 230c, and the rotating member 400c rotates in the tightening direction R1 at a second speed, and the second speed is different from the first speed.

[0160] Please refer to Figure 16, together with Figures 14 and 15, wherein Figure 16 illustrates a side cross-sectional schematic diagram of the driving device 100c of the third embodiment shown in Figure 13. The rotating member 400c may include an annular disc 460c, a protruding shaft 470c, and a driving hole 480c. The annular disc 460c is pivotally mounted on the four planetary gears 253c, the protruding shaft 470c extends downward from the annular disc 460c, and the driving hole 480c is located at the distal end of the protruding shaft 470c.

[0161] The driving device 100c further includes a housing 300c, which includes a shell 310c and a base 320c. The structure of the shell 310c is similar to that of the shell 310a in the first embodiment, and the base 320c may include a center hole 324c. When the rotating member 400c is disposed within the housing 300c, the protruding shaft 470c may protrude from the center hole 324c. The driving hole 480c may be coupled to a workpiece, such as a nut or screw. Turning the knob 210c drives the rotating member 400c to rotate the workpiece. Thus, the driving device 100c can be used as a screwdriver.

[0162] Please refer to Figures 17, 18, and 19, wherein Figure 17 is a perspective view of a cord-fastening device 100d according to a fourth embodiment of the present invention, Figure 18 is an exploded view of the cord-fastening device 100d of the fourth embodiment of Figure 17, and Figure 19 is another exploded view of the cord-fastening device 100d of the fourth embodiment of Figure 17. The cord-fastening device 100d includes a housing 300d, a rotation drive mechanism (not shown in the fourth embodiment), and a rotating member 400d.

[0163] The rotary drive mechanism may include a ratchet arm 222d, a knob 210d, and a plurality of stepless drive teeth 272d. The stepless drive teeth 272d correspond to the ratchet arm 222d. Rotating the knob 210d in the tightening direction R1 does not drive the stepless drive teeth 272d, but rotating the knob 210d in the release direction R2 does drive the stepless drive teeth 272d. Therefore, when the knob 210d is rotated in the release direction R2, the stepless drive teeth 272d deflect the ratchet arm 222d, disengaging the ratchet arm 222d from the engaging teeth 312d, thereby allowing the tie line to be partially released.

[0164] Specifically, the rotation drive mechanism may further include a tightening drive arm 261d and a releasing drive arm 271d, the knob 210d includes a plurality of first knob teeth 211d and a plurality of second knob teeth 212d, the tightening drive arm 261d selectively engages with the aforementioned plurality of first knob teeth 211d, the releasing drive arm 271d selectively engages with the aforementioned plurality of second knob teeth 212d, and the aforementioned plurality of stepless drive teeth 272d are rotationally linked with the releasing drive arm 271d and correspond to the ratchet arm 222d. When the knob 210d is rotated in the tightening direction R1, the aforementioned multiple first knob teeth 211d drive the tightening drive arm 261d to drive the transmission gear 255d to rotate in the tightening direction R1; when the knob 210d is rotated in the release direction R2, the aforementioned multiple second knob teeth 212d drive the release drive arm 271d, so that the aforementioned multiple stepless drive teeth 272d rotate in the release direction R2 and deflect the ratchet arm 222d, so that the ratchet arm 222d disengages from the engaging tooth 312d, thereby allowing the line to be released steplessly.

[0165] The rotational drive mechanism may further include a tightening drive member 260d, which includes a tightening drive disc body 262d, three tightening drive arms 261d, and a rotating shaft 263d. The tightening drive arms 261d protrude from the tightening drive disc body 262d and extend along the circumference of the tightening drive disc body 262d. The rotating shaft 263d protrudes downward from the tightening drive disc body 262d. The rotating shaft 263d can engage with the transmission gear 255d to rotate in linkage.

[0166] The rotary drive mechanism may further include a release drive member 270d, which includes a release drive disc body 273d, three release drive arms 271d, a through hole 274d and a stepless drive tooth 272d. The through hole 274d passes through the release drive disc body 273d, the three release drive arms 271d are located on the upper surface of the release drive disc body 273d and surround the through hole 274d, and the stepless drive tooth 272d is located on the lower surface of the release drive disc body 273d.

[0167] The first knob tooth 211d and the second knob tooth 212d are located on the inner circumference of the knob 210d, with the first knob tooth 211d located above the second knob tooth 212d along axis X1. The tightening actuator 260d and the release actuator 270d can be accommodated within the knob 210d, with the release actuator 270d covering the detent 220d. The tightening actuator 260d is sandwiched between the release actuator 270d and the top surface of the knob 210d. Thus, the tightening actuator arm 261d corresponds to the first knob tooth 211d, the release actuator arm 271d corresponds to the second knob tooth 212d, the ratchet arm 222d corresponds to the stepless actuator tooth 272d, and the rotation axis 263d protrudes downward through the through hole 274d.

[0168] Please refer to Figures 20, 21, 22, 23, 24 and 25, wherein Figure 20 is a side view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 17, Figure 21 is another side view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 17, Figure 22 is a top view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 20 along the cutting line 22-22, Figure 23 is a top view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 20 along the cutting line 23-23, Figure 24 is a top view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 20 along the cutting line 24-24, and Figure 25 is a top view schematic cross-sectional diagram of the tie wire fastening device 100d of the fourth embodiment of Figure 20 along the cutting line 25-25. As shown in Figures 20, 22, and 25, when the knob 210d is not yet pulled up and is in the first position and rotated in the tightening direction R1, the first knob tooth 211d engages the tightening drive arm 261d, thereby driving the tightening drive member 260d to rotate in the tightening direction R1. At this time, the second knob tooth 212d is disengaged from the release drive arm 271d, and the release drive member 270d is not driven. Therefore, the tightening drive member 260d can drive the transmission gear 255d to drive the rotating member 400d to tighten the tie line. During the initial tightening process, since the tie line tension is low, the coupling portion 241d can engage and drive the gear member 230d, causing the rotating member 400d to tighten the tie line at the first speed.

[0169] When the tension of the tie line is too high, the coupling portion 241d disengages the gear member 230d, causing the tie line to be tightened at a speed lower than the first speed to the second speed, thereby slowly tightening the tie line. Furthermore, when the knob 210d is not operated, the distal end of the ratchet arm 222d engages with the engaging tooth 312d, thereby preventing the rotating member 400d from releasing the tie line in the release direction R2.

[0170] When the knob 210d is rotated in the release direction R2, the second knob tooth 212d engages the release drive arm 271d, causing the release drive member 270d to rotate in the release direction R2. At this point, the first knob tooth 211d disengages from the tightening drive arm 261d, and the tightening drive member 260d is not driven. As shown in FIG24 , the ratchet arm 222d is pushed by the stepless drive tooth 272d to deflect, enabling stepless release of the tie line. It should be noted that stepless release of the tie line means that the stepless drive tooth 272d pushes the ratchet arm 222d, temporarily disengaging the engaging tooth 312d before returning to its original position. Therefore, the tie line is only released a short distance, unlike full release. As shown in FIG21 , the tie line can be fully released by pulling up on the knob 210d.

[0171] Please refer to Figures 26 and 27. Figure 26 illustrates an exploded view of a tether fastening device 100e according to a fifth embodiment of the present invention, and Figure 27 illustrates another exploded view of the tether fastening device 100e of the fifth embodiment of Figure 26. The tether fastening device 100e includes a rotation drive mechanism (not shown in the fifth embodiment) and a rotating member 400e.

[0172] The rotation drive mechanism includes a knob 210e, a sun gear 252e, a plurality of planetary gears 253e, a gear element 230e, and a coupling portion 241e. The sun gear 252e is driven by the knob 210e, the plurality of planetary gears 253e engage with the sun gear 252e, the gear element 230e corresponds to the planetary gears 253e, and the coupling portion 241e is located within the gear element 230e and corresponds to the protruding teeth 232e.

[0173] The knob 210e may include a plurality of pivots 213e protruding downward from its top surface. Each planetary gear 253e may be pivotally mounted on each pivot 213e. The sun gear 252e is positioned between and meshed with the four planetary gears 253e. The rotation drive mechanism may further include a transmission gear 255e positioned below and meshed with the sun gear 252e. The transmission gear 255e may also be positioned above the rotating member 400e and rotated in conjunction with the rotating member 400e.

[0174] The gear member 230e may include a plurality of inner ring teeth 231e and a plurality of protruding teeth 232e, with the inner ring teeth 231e positioned above the protruding teeth 232e. The coupling member 240e may be first placed within the gear member 230e such that the coupling portion 241e corresponds to the protruding teeth 232e. The planetary gear 253e may then be positioned above the coupling member 240e and aligned with the inner ring teeth 231e.

[0175] The rotation driving mechanism may further include a detent 220e. The detent 220e may be located below the gear 230e and rotated in conjunction with the gear 230e.

[0176] The tether fastening device 100e may further include a housing (not shown in the fifth embodiment), the housing including a shell 310e and a base 320e. The shell 310e includes engaging teeth 312e adjacent to the base 320e. When the rotary drive mechanism is coupled to the housing, the ratchet arm 222e of the detent member 220e may correspond to the engaging teeth 312e.

[0177] When the knob 210e is rotated in the tightening direction R1 and the load on the coupling member 240e does not exceed the tolerance threshold, the knob 210e drives the gear member 230e and the planetary gear 253e to rotate the rotating member 400e at a first speed to tighten and take up the line. Conversely, when the load on the coupling member 240e is greater than or equal to the tolerance threshold, the knob 210e drives the planetary gear 253e to rotate relative to the gear member 230e, causing the rotating member 400e to tighten and take up the line at a second speed. In the fifth embodiment, the second speed can be faster than the first speed. Therefore, it can be seen that the present invention can adjust the rotation speed by first rotating the rotating member at a faster speed and then at a slower speed, or first rotating the rotating member at a slower speed and then at a faster speed.

[0178] Please refer to Figures 28 and 29 , wherein Figure 28 illustrates an exploded schematic diagram of a tie-line fastening device 100f according to a sixth embodiment of the present invention, and Figure 29 illustrates another exploded schematic diagram of the tie-line fastening device 100f of the sixth embodiment of Figure 28 . The tie-line fastening device 100f has a similar structure to the tie-line fastening device 100a of the first embodiment and includes a rotational drive mechanism (not shown in the sixth embodiment) and a rotating member 400f. The rotational drive mechanism includes a coupling member 240f, a plurality of planetary gears 253f, a gear member 230f, and a knob 210f.

[0179] The difference lies in that the coupling portion 241f of the coupling member 240f includes tension teeth 2411f located at the distal end of the coupling portion 241f. Furthermore, each of the protruding teeth 232f of the gear member 230f may include a tooth groove 2321f. When the coupling portion 241f engages with the protruding teeth 232f, the tension teeth 2411f engage with the tooth groove 2321f. The tension teeth 2411f help generate a greater pulling force, so that when the coupling portion 241f rotates relative to the protruding teeth 232f, the coupling portion 241f must overcome the greater pulling force before it can jump from one protruding tooth 232f to the adjacent protruding tooth 232f. Other structural similarities with the first embodiment of the tie-down fastening device 100a are not further described.

[0180] Please refer to Figures 30 and 31 , along with Figures 28 and 29 . Figure 30 illustrates a side cross-sectional schematic diagram of the tie-line fastening device 100f according to the sixth embodiment of Figure 28 , and Figure 31 illustrates another side cross-sectional schematic diagram of the tie-line fastening device 100f according to the sixth embodiment of Figure 28 . As shown in Figures 28 to 30 , the knob 210f is not yet pulled up and is in the first position. The coupling portion 241f engages the protruding teeth 232f, and the planetary gear 253f rotates with the gear member 230f, driving the rotating member 400f to rotate at a first speed in the tightening direction R1. If the tension of the tie-line increases, the coupling portion 241f disengages from the protruding teeth 232f, allowing the planetary gear 253f to rotate relative to the gear member 230f simultaneously about the axis X1 and the pivot, causing the rotating member 400f to rotate at a second speed.

[0181] As shown in FIG. 31 , when the knob 210 f is pulled up along the axis X1 to the second position, the rotating member 400 f is not restricted and can rotate in the releasing direction R2 to release the tie line.

[0182] Please refer to Figures 32 and 33 , wherein Figure 32 illustrates an exploded view of a tether fastening device 100g according to a seventh embodiment of the present invention, and Figure 33 illustrates another exploded view of the tether fastening device 100g of the seventh embodiment of Figure 32 . The tether fastening device 100g includes a housing (not shown in the seventh embodiment), a rotation drive mechanism (not shown in the seventh embodiment), and a rotating member 400g.

[0183] The rotary drive mechanism includes a gear 230g, a plurality of planetary gears 253g, a coupling 240g, a rotary transmission member 260g, and a knob 210g. The planetary gears 253g are located within the gear 230g, while the coupling 240g is located within the gear 230g and above the planetary gears 253g. The rotary transmission member 260g is located above the gear 230g, and the knob 210g is coupled to the rotary transmission member 260g. When the knob 210g is rotated in the tightening direction R1, the rotary transmission member 260g drives the coupling 240g, which in turn rotates the gear 230g and the planetary gears 253g in the tightening direction R1, causing the rotary member 400g to rotate at a first speed. When the line tension increases, the coupling 240g loses its ability to drive the gear 230g, causing the planetary gears 253g to rotate relative to the gear 230g, causing the rotary member 400g to rotate at a second speed. When the knob 210g is rotated in the release direction R2, the rotation transmission member 260g rises along the axis X1, allowing the rotation member 400g to rotate in the release direction R2.

[0184] The structures of the gear member 230g and the coupling member 240g are similar to those of the gear member 230a and the coupling member 240a in the first embodiment, and are not described again.

[0185] The knob 210g may include three guide rails 214g and three driving protrusions 215g. Each guide rail 214g is recessed on the inner circumference of the knob 210g, and each driving protrusion 215g is convexly disposed on the inner circumference and located below the top dead center of the guide rail 214g.

[0186] The rotary transmission member 260g can be located within the knob 210g and can include a rotary disc 263g, three guides 264g, three rotary transmission arms 261g, and a transmission boss 265g. The guides 264g radially protrude from the rotary disc 263g. The rotary transmission arms 261g extend circumferentially from one side of the guides 264g. The transmission boss 265g protrudes downward from the rotary disc 263g and can be rotationally restrained with the transmission gear 255g. The rotary transmission arms 261g can engage with the driving boss 215g in the tightening direction R1. Each guide 264g is located within a respective guide rail 214g and can initially be located at the bottom dead center of each guide rail 214g.

[0187] Please refer to Figures 34 and 35 together with Figures 32 and 33. Figure 34 is a side cross-sectional schematic diagram of the tie-line fastening device 100g according to the seventh embodiment of Figure 32, and Figure 35 is another side cross-sectional schematic diagram of the tie-line fastening device 100g according to the seventh embodiment of Figure 32. As shown in Figures 32 to 34, the rotary transmission member 260g is not raised but is in the lowered position. Rotating the knob 210g in the tightening direction R1 drives the rotary transmission member 260g to rotate, and the coupling member 240g drives the gear member 230g. Therefore, the coupling member 240g, the transmission gear 255g, the gear member 230g, and the planetary gear 253g move simultaneously, thereby driving the rotary member 400g to rotate at the first speed. When the line tension increases, the coupling member 240g disengages from the gear member 230g in the tightening direction R1, so that the gear member 230g is not driven to rotate. The planetary gear 253g rotates relative to the gear member 230g around the axis X1, thereby driving the rotating member 400g to rotate at the second speed.

[0188] As shown in FIG35 , to fully release the tie line, the knob 210g is rotated in the release direction R2. This causes the rotary transmission member 260g to be unable to rotate accordingly, so the rotary transmission arm 261g disengages from the driving protrusion 215g. The knob 210g is then rotated relative to the rotary transmission member 260g, causing the guide portion 264g to move to the top dead center position within each guide rail 214g, and the rotary transmission member 260g to rise to the raised position. This disengages the transmission gear 255g from the sun gear 252g, allowing the rotary member 400g to rotate in the release direction R2.

[0189] Please refer to Figures 36 and 37 , wherein Figure 36 illustrates an exploded schematic diagram of a tether securing device 100h according to an eighth embodiment of the present invention, and Figure 37 illustrates another exploded schematic diagram of the tether securing device 100h of the eighth embodiment of Figure 36 . The tether securing device 100h may include a housing (not shown in the eighth embodiment), a rotational drive mechanism (not shown in the eighth embodiment), and a rotating member 400h. The rotational drive mechanism includes a gear member 230h, a coupling member 240h, a transmission gear 255h, a plurality of planetary gears 253h, a sun gear 252h, and a knob 210h.

[0190] The housing may include a shell 310h, which may include a shell annular wall 311h, an upper plate 314h, and a top flange 317h. The upper plate 314h is connected to the upper open end of the shell annular wall 311h and includes a plate hole (not shown) and a plurality of plate teeth 3141h surrounding the plate hole. The top flange 317h radially protrudes from the upper open end of the shell annular wall 311h. It should be noted that in the eighth embodiment, the outer diameter of the upper plate 314h is larger than the outer diameter of the shell annular wall 311h, so that the outer edge of the upper plate 314h forms the top flange 317h, but this is not limiting.

[0191] Gear component 230h is disposed within housing 310h and below upper plate 314h. Gear component 230h may include a cylinder wall 233h, an upper ring plate 234h, an inner convex ring, a plurality of inner ring teeth 231h, a plurality of convex teeth 232h, a plurality of coupling teeth 235h, and three ratchet arms 236h. The cylinder wall 233h includes an upper cylinder wall portion (not shown) and a lower cylinder wall portion (not shown) that are interconnected. The upper ring plate 234h is connected to the upper end of the upper cylinder wall portion and includes an inner hole. The inner convex ring is protruded from the wall of the inner hole. The inner ring teeth 231h are disposed on the inner side of the lower cylinder wall portion, the convex teeth 232h are disposed on the inner side of the upper cylinder wall portion and are located above the inner ring teeth 231h, and the coupling teeth 235h may protrude downward from the upper ring plate 234h. The ratchet arm 236h may protrude from the upper tube wall and extend along the circumferential direction. The ratchet arm 236h corresponds to the engaging teeth (not shown in the eighth embodiment).

[0192] The coupling member 240h may include a latching claw 247h coupled to the gear member 230h. When the coupling member 240h moves from an engaged position to a disengaged position along the axis X1, the latching claw 247h moves relative to the gear member 230h along the axis X1. When the coupling member 240h is in the disengaged position, rotation of the knob 210h in the tightening direction R1 drives the rotating member 400h to rotate at a second speed. Furthermore, when the coupling member 240h is in the disengaged position, it contacts a stop surface of the transmission gear 255h. Operating the knob 210h causes the transmission gear 255h to rise, causing the stop surface to push the coupling member 240h back to the engaged position along the axis X1.

[0193] Specifically, the coupling member 240h is disposed within the gear member 230h and may further include a coupling ring body 242h, three limiting portions 249h, three coupling portions 241h, three engaging claws 247h, and three limiting blocks 248h. Each limiting portion 249h radially protrudes from the coupling ring body 242h and extends upward from a lower edge. Each limiting portion 249h includes an upward-facing limiting tooth corresponding to the engaging tooth 235h. Each coupling portion 241h extends from one side of each limiting portion 249h along the circumference of the coupling ring body 242h. The three engaging claws 247h are located on the outer circumference of the coupling ring body 242h and engage with the inner protruding ring of the gear member 230h. The three limiting blocks 248h radially protrude from the inner circumference of the coupling ring body 242h.

[0194] The transmission gear 255h may include a gear body (not labeled), three external latching portions 2552h, and three sliding grooves 2551h. The three external latching portions 2552h are located on the outside of the gear body and extend upward from the bottom edge. Each external latching portion 2552h may include two latching tooth segments (not labeled) extending along axis X1 and a stop surface. Each latching tooth segment includes latching teeth, and the stop surface is located between the two latching tooth segments. Each sliding groove 2551h is located between the two latching tooth segments of each external latching portion 2552h, and the stop surface corresponds to the sliding groove 2551h. The gear body (not labeled) may include an upper half and a lower half. The upper half includes a hexagonal internal latching hole, and the lower half engages with the sun gear 252h. The transmission gear 255h can be inserted into the coupling ring body 242h.

[0195] The rotary drive mechanism may further include a rotary transmission member 260h, which can be rotatably linked to the transmission gear 255h. The rotary transmission member 260h can be located within the knob 210h and can include a rotary disk 263h, three guide portions 264h, three rotary transmission arms 261h, and a transmission boss 265h. The transmission boss 265h is located below the rotary disk 263h and protrudes into the upper half of the gear body, capable of engaging with the hexagonal socket of the gear body.

[0196] The knob 210h may include three guide rails 214h and three driving protrusions 215h, which can drive the rotating transmission member 260h in the tightening direction R1 and raise the rotating transmission member 260h in the releasing direction R2. The knob 210h may also include a knob locking portion 216h. When the knob 210h is covered with the housing 310h, the knob locking portion 216h can be located below the top flange 317h to form a fixed connection with the housing 310h.

[0197] The line fastening device 100h may further include a connecting unit (not marked), which may include a screw 520h passing through the lower half of the gear body toward the upper half and locking into the transmission boss 265h, thereby limiting the position of the gear part 230h, the coupling part 240h, the transmission gear 255h, the rotating transmission part 260h and the housing 310h.

[0198] Please refer to Figures 38, 39, and 40, together with Figures 36 and 37. Figure 38 is a side cross-sectional schematic diagram of the tie-line fastening device 100h of the eighth embodiment shown in Figure 36. Figure 39 is another side cross-sectional schematic diagram of the tie-line fastening device 100h of the eighth embodiment shown in Figure 36. Figure 40 is yet another side cross-sectional schematic diagram of the tie-line fastening device 100h of the eighth embodiment shown in Figure 36. As shown in Figures 36 to 38, the rotary transmission member 260h is not raised but is in the lowered position, the transmission gear 255h is locked with the rotary transmission member 260h, and at this time, the outer engaging portion 2552h is not engaged with the top plate teeth 3141h. The coupling member 240h is in the engaged position, with the limiting teeth of the limiting portion 249h engaging the engaging teeth 235h of the gear member 230h. The coupling portion 241h corresponds to the protruding teeth 232h of the gear member 230h, and the engaging claw 247h is located above the inner protruding ring of the gear member 230h. At this point, rotating the knob 210h in the tightening direction R1 drives the rotating transmission member 260h, which in turn drives the transmission gear 255h and the coupling member 240h, driving the gear member 230h and the planetary gear 253h simultaneously, thereby driving the rotating member 400h to rotate at the first speed. As shown in Figure 39, when the tension on the tie line increases, the load on coupling member 240h exceeds the tolerance threshold, causing coupling member 240h to move from the engaged position to the disengaged position along axis X1. Specifically, since coupling portion 241h is unable to drive gear member 230h, the limiting tooth is pushed downward along the inclined surface of coupling tooth 235h, causing coupling member 240h to move downward to the disengaged position. Limit block 248h moves downward within groove 2551h to contact the stop surface, disengaging the limiting tooth from coupling tooth 235h. The engaging claw 247h is positioned below the inner convex ring of gear member 230h. If knob 210h is continuously rotated in tightening direction R1, since coupling member 240h is unable to drive gear member 230h, planetary gear 253h rotates relative to gear member 230h about axis X1, thereby driving rotating member 400h at the second speed.

[0199] As shown in FIG40 , when the line is to be fully released, the knob 210h can be rotated in the release direction R2. The knob 210h rotates relative to the rotating transmission member 260h. The rotating transmission member 260h rises to the rising position, driving the transmission gear 255h to rise, so that its stop surface also drives the coupling member 240h back to the engagement position, and allows the outer clamping portion 2552h of the transmission gear 255h to engage with the top plate tooth 3141h.

[0200] Please refer to Figures 41 and 42, wherein Figure 41 illustrates an exploded view of a tether fastening device 100i according to a ninth embodiment of the present invention, and Figure 42 illustrates another exploded view of the tether fastening device 100i of the ninth embodiment of Figure 41. The tether fastening device 100i includes a housing (not shown in the ninth embodiment), a rotation drive mechanism (not shown in the ninth embodiment), and a rotating member 400i.

[0201] The rotary drive mechanism includes a gear 230i, a plurality of planetary gears 253i, a coupling 240i, and a knob 210i. The planetary gears 253i are located within the gear 230i. The coupling 240i is located within the gear 230i and above the planetary gears 253i. The knob 210i is operably coupled to the aforementioned planetary gears 253i. The coupling 240i moves along the axis X1 between an engaged position and a disengaged position. When the coupling 240i is in the engaged position, the coupling 240i and the gear 230i are engaged and rotated in conjunction. Rotation of the knob 210i in the tightening direction R1 drives the coupling 240i, the gear 230i, and the planetary gears 253i, thereby driving the rotary member 400i, causing the rotary member 400i to rotate at a first speed. When the line tension increases, the coupling member 240i moves to the separation position, the coupling member 240i disengages from the gear member 230i, and the knob 210i rotates in the tightening direction R1 to drive the planetary gear 253i to rotate relative to the gear member 230i to link the rotating member 400i, so that the rotating member 400i rotates at the second speed.

[0202] Please refer to Figures 43, 44, and 45, together with Figures 41 and 42. Figure 43 illustrates a side cross-sectional schematic diagram of the tie-line fastening device 100i of the ninth embodiment of Figure 41. Figure 44 illustrates another side cross-sectional schematic diagram of the tie-line fastening device 100i of the ninth embodiment of Figure 41. Figure 45 illustrates yet another side cross-sectional schematic diagram of the tie-line fastening device 100i of the ninth embodiment of Figure 41. The gear member 230i may include a cylindrical wall 233i, an upper ring plate 234i, a plurality of inner ring teeth 231i, a plurality of protruding teeth 232i, a plurality of stop ratchet teeth 237i, and three ratchet arms 236i. The upper ring plate 234i protrudes within the cylindrical wall 233i. The inner ring teeth 231i are disposed within the cylindrical wall 233i and are located below the upper ring plate 234i. The protruding teeth 232i may protrude downward from the upper ring plate 234i and be located above the inner ring teeth 231i. The stopping ratchet teeth 237i are annularly disposed inside the cylindrical wall 233i and located above the upper ring plate 234i. Each ratchet arm 236i protrudes from the cylindrical wall 233i.

[0203] The coupling member 240i may include a barrel portion 245i, a disk portion 246i, a plurality of coupling portions 241i, three engaging claws 247i, and three stop blocks 248i. The disk portion 246i is connected to the lower end of the barrel portion 245i. The diameter of the barrel portion 245i is smaller than that of the disk portion 246i, and the barrel portion 245i is configured to engage with the transmission gear 255i. The coupling portion 241i has a tooth structure and protrudes from the disk portion 246i, corresponding to the protruding teeth 232i. The three engaging claws 247i are protruded from the outer wall (not shown) of the barrel portion 245i and can be coupled to the upper ring plate 234i of the gear member 230i. The three stop blocks 248i protrude radially from the inner wall (not shown) of the barrel portion 245i and are adjacent to the upper end of the barrel portion 245i.

[0204] The transmission gear 255i can be engaged with the coupling member 240i. In addition to its shape corresponding to the outer wall of the cylindrical portion 245i, the transmission gear 255i also includes three sliding grooves 2551i corresponding to the three stop blocks 248i. When the coupling member 240i moves between the engaged and disengaged positions, each stop block 248i can move within the sliding grooves 2551i. The transmission gear 255i can also include a stop surface (not shown) located at the lower end of each sliding groove 2551i. When the coupling member 240i is in the disengaged position, it can contact the stop surface.

[0205] The rotary drive mechanism may further include a rotary transmission member 260i, which is located above the gear member 230i and can be selectively coupled to the gear member 230i, and the rotary transmission member 260i is rotated in conjunction with the coupling member 240i; when the tension of the line is relatively small, the coupling member 240i is located in the engaged position, and the knob 210i is rotated in the tightening direction R1 to drive the rotary transmission member 260i to rotate the gear member 230i, thereby driving the rotating member 400i to rotate at a first speed; conversely, when the tension of the line increases, the tension attempts to drive the gear member 230i to rotate in the release direction R2, and continuously rotating the knob 210i in the tightening direction R1 can cause the coupling member 240i to descend to move to the separation position, and cause the rotary transmission member 260i to rotate relative to the gear member 230i to drive the rotating member 400i to rotate at a second speed.

[0206] Specifically, the knob 210i may include three guide rails 214i and three driving protrusions 215i. Each guide rail 214i is recessed on the inner circumference of the knob 210i, and each driving protrusion 215i is convexly disposed on the inner circumference and located below the upper dead point of the guide rail 214i.

[0207] The rotary transmission member 260i can be located within the knob 210i and may include a rotary disc 263i, three guide portions 264i, three rotary transmission arms 261i, three rotary linkage arms 262i, three forced-in teeth 267i, and a rotary hole 266i. The guide portions 264i radially protrude from the rotary disc 263i. The rotary transmission arms 261i extend circumferentially from one side of the guide portions 264i. The rotary linkage arms 262i are located below the rotary transmission arms 261i and extend circumferentially. The rotary linkage arms 262i are circumferentially longer but radially inwardly contracted relative to the rotary transmission arms 261i. Each forced-in teeth 267i is located on each rotary linkage arm 262i and is no taller than one-half of the height of each rotary linkage arm 262i. The rotary hole 266i can be rotationally limited by the transmission gear 255i.

[0208] The rotating transmission arm 261i can be engaged with the driving protrusion 215i in the tightening direction R1. Each guide portion 264i is located within each guide rail 214i and can be initially located at the bottom dead center of each guide rail 214i. The rotating linkage arm 262i can correspond to the stop ratchet 237i.

[0209] The rotary drive mechanism may further include a gear wheel 270i, which may be located above the gear member 230i and include a plurality of external teeth 271i and a plurality of internal teeth 272i. The external teeth 271i may be engaged with a plurality of engaging teeth 312i of the outer shell (not shown), and the external teeth 271i are located below the internal teeth 272i along the axis X1.

[0210] As shown in Figures 41 to 43, the rotary transmission member 260i is not raised but in the lowered position. The rotary linkage arm 262i corresponds to the stop ratchet tooth 237i and does not correspond to the inner convex tooth 272i. The forced tooth portion 267i does not correspond to the stop ratchet tooth 237i or the inner convex tooth 272i. The coupling member 240i is in the engaged position, and the engaging claw 247i is located above the upper ring plate 234i of the gear member 230i. Rotating the knob 210i in the tightening direction R1 drives the rotary transmission member 260i. The coupling portion 241i engages with the convex tooth 232i, driving the gear member 230i. As a result, the coupling member 240i, the transmission gear 255i, the gear member 230i, and the planetary gear 253i all move simultaneously, driving the rotary member 400i to rotate at the first speed. As shown in Figure 44, when the line tension increases, the gear part 230i and the planetary gear 253i are subjected to increased force and rotate in the release direction R2, causing the coupling part 240i to be pushed by the inclined surface of the convex tooth 232i relative to the transmission gear 255i to move downward along the axis X1 to a separation position, and the engaging claw 247i is moved to the bottom of the upper ring plate 234i of the gear part 230i, and the limit block 248i moves downward in the sliding groove 2551i to contact the stop surface. At this time, the gear part 230i is not driven to rotate, and the planetary gear 253i rotates around the axis X1 relative to the gear part 230i, and can drive the rotating part 400i to rotate at the second speed.

[0211] As shown in FIG45 , to fully release the tie line, the knob 210 i is rotated in the release direction R2. At this point, the engagement between the rotation link arm 262 i and the stop ratchet 237 i prevents the rotation of the rotary transmission member 260 i from following the rotation. Consequently, the rotation link arm 261 i disengages from the driving protrusion 215 i. The knob 210 i rotates relative to the rotary transmission member 260 i, causing the guide portion 264 i to move to the top dead center position within each guide rail 214 i. The rotary transmission member 260 i rises to the raised position, and the stop surface of the transmission gear 255 i also drives the coupling member 240 i upward and back to the engaged position. At this point, the rotation link arm 262 i and the forced engagement tooth portion 267 i align with the inner protruding tooth 272 i.

[0212] The user can then rotate the knob 210i in the tightening direction R1. This prevents the rotary linkage arm 262i from rotating in the tightening direction R1 due to the engagement of the internally protruding teeth 272i. This causes the knob 210i to rotate relative to the rotary transmission member 260i, gradually lowering the rotary transmission member 260i to the lowered position. The forced engagement teeth 267i allow the rotary linkage arm 262i to remain engaged with the internally protruding teeth 272i even when the rotary linkage arm 260i loses its elasticity, thereby assisting in lowering the rotary transmission member 260i.

[0213] Please refer to Figures 46 and 47, wherein Figure 46 illustrates an exploded view of a cord fastening device 100j according to a tenth embodiment of the present invention, and Figure 47 illustrates another exploded view of the cord fastening device 100j of the tenth embodiment shown in Figure 46. The cord fastening device 100j includes a rotation drive mechanism (not shown in the tenth embodiment) and a rotating member 400j.

[0214] The rotation drive mechanism may include a knob 210j, a rotation transmission member 260j, a transmission gear 255j, a coupling portion 241j, a gear member 230j, and a plurality of planetary gears 253j. The rotation transmission member 260j is coupled to the knob 210j, the transmission gear 255j is rotationally limited to the rotation transmission member 260j, the coupling portion 241j is rotationally limited to the transmission gear 255j, and the gear member 230j is selectively coupled to the coupling portion 241j. When the knob 210j is rotated in the tightening direction R1, the rotation transmission member 260j drives the coupling portion 241j, the gear member 230j, and the planetary gears 253j to rotate together, and the rotation member 400j rotates at a first speed. When the knob 210j continues to rotate in the tightening direction R1, driving the rotation transmission member 260j, the coupling portion 241j, and the planetary gears 253j to rotate relative to the gear member 230j, the rotation member 400j rotates at a second speed.

[0215] The tether securing device 100j may include a coupling member 240j. The coupling member 240j may include a coupling portion 241j and a plurality of limiting teeth (not shown). The gear member 230j may include a plurality of engaging teeth 235j. When the limiting teeth engage with the engaging teeth 235j, the coupling member 240j limits the gear member 230j. When a load applied to the coupling member 240j exceeds or equals a load threshold, the coupling member 240j moves along the axis X1 from an engaged position to a disengaged position, disengaging the limiting teeth from the engaging teeth 235j. The coupling member 240j no longer limits the gear member 230j.

[0216] Specifically, the coupling member 240i may include a coupling ring body 242j, three limiting portions 249j, three coupling portions 241j, and three limiting blocks 248j. Each limiting portion 249j radially protrudes from the coupling ring body 242j and extends upward from the lower edge. Each limiting portion 249j includes upward-facing limiting teeth. Each coupling portion 241j extends from one side of each limiting portion 249j along the circumference of the coupling ring body 242j.

[0217] The gear component 230j may include a cylinder wall 233j, an upper ring plate (not marked in the 10th embodiment), a plurality of inner ring teeth 231j, a plurality of convex teeth 232j, the aforementioned plurality of combining teeth 235j and three ratchet arms 236j. The cylinder wall 233j includes an upper cylinder wall portion (not marked) and a lower cylinder wall portion (not marked) that are connected to each other. The upper ring plate is connected to the upper end of the upper cylinder wall portion. The inner ring teeth 231j are arranged in a ring inside the lower cylinder wall portion. The convex teeth 232j are arranged in a ring inside the upper cylinder wall portion and are located above the inner ring teeth 231j. The combining teeth 235j can protrude downward from the upper ring plate and correspond to the limiting teeth. The ratchet arms 236j can protrude from the upper cylinder wall portion and extend circumferentially. The ratchet arms 236j correspond to the engaging teeth 312j.

[0218] The transmission gear 255j may include a gear body (not shown), three external engaging portions 2552j, three sliding grooves 2551j, and a transmission pawl 2553j. The three external engaging portions 2552j are located on the outside of the gear body and extend upward from the bottom edge. Each external engaging portion 2552j may include two tooth segments (not shown) extending along axis X1 and a stop surface. Each tooth segment includes a tooth, and the stop surface is located between the two tooth segments. Each sliding groove 2551j is located between the two tooth segments of each external engaging portion 2552j, and the stop surface corresponds to the sliding groove 2551j. The gear body (not shown) includes an upper section and a lower section. The upper section is shaped to engage with the transmission boss 265j, while the lower section engages with the sun gear 252j. The transmission pawl 2553j protrudes upward from the inner surface of the gear body. The transmission gear 255j can be inserted into the coupling ring body 242j, and each limit block 248i protrudes into each sliding groove 2551j.

[0219] The rotary transmission member 260j can be rotatably linked with the coupling member 240j. The rotary transmission member 260j can be located within the knob 210j and can include a rotary disk 263j, three guide portions 264j, three rotary transmission arms 261j, and a transmission boss 265j. The transmission boss 265j is located below the rotary disk 263j and engages with the transmission gear 255j.

[0220] The rotary drive mechanism may further include a toothed disc 270j. The toothed disc 270j may be located above the gear member 230j and include a plurality of externally protruding teeth 271j and a plurality of internally protruding teeth 272j. The externally protruding teeth 271j may engage with a plurality of engaging teeth 312j on the housing (not shown). The internally protruding teeth 272j extend downwardly and correspond to the engaging teeth on the engaging tooth section of the transmission gear 255j. It should be noted that the toothed disc 270j may be similar to the upper plate 314h of the eighth embodiment, except that the upper plate 314h is integrally connected to the housing 310h, while the toothed disc 270j is a separate component.

[0221] The knob 210j of the rotary drive mechanism of the tenth embodiment is the same as the knob 210i of the rotary drive mechanism of the ninth embodiment, and can drive the rotary transmission member 260j to rotate the tightening line in the tightening direction R1, and drive the rotary transmission member 260j to rise in the releasing direction R2. The details are not repeated here.

[0222] Please refer to Figures 48, 49, and 50, together with Figures 46 and 47, wherein Figure 48 is a side cross-sectional schematic diagram of the tie-line fastening device 100j of the tenth embodiment shown in Figure 46, Figure 49 is another side cross-sectional schematic diagram of the tie-line fastening device 100j of the tenth embodiment shown in Figure 46, and Figure 50 is yet another side cross-sectional schematic diagram of the tie-line fastening device 100j of the tenth embodiment shown in Figure 46. As shown in Figures 46 to 48, the rotary transmission member 260j is not raised but is in the lowered position, and the transmission gear 255j is coupled to the rotary transmission member 260j by inserting its transmission claw 2553j therein, and the transmission claw 2553j can rest on the upper portion of the toothed disc 270j. The coupling member 240j is in the engaged position, with the limiting teeth of the limiting portion 249j engaged with the engaging teeth 235j. The coupling portion 241j corresponds to the protruding teeth 232j, and the engaging claw (not numbered in the tenth embodiment) is located above the inner protruding ring of the gear member 230j. At this point, rotating the knob 210j in the tightening direction R1 drives the rotating transmission member 260j, which in turn drives the transmission gear 255j and the coupling member 240j, driving the gear member 230j and the planetary gear 253j simultaneously, thereby driving the rotating member 400j to rotate at the first speed. As shown in Figure 49, when the tension on the tie line increases, the load on coupling member 240j exceeds the tolerance threshold, and coupling portion 241j is unable to drive gear member 230j. The limiting tooth is pushed downward along the inclined surface of coupling tooth 235j, causing coupling member 240j to move downward to the disengaged position. Limit block 248j moves downward within groove 2551j to contact the stop surface, and the limiting tooth disengages from coupling tooth 235j. At this point, if knob 210j is continuously rotated in tightening direction R1, since coupling member 240j is unable to drive gear member 230j, planetary gear 253j rotates relative to gear member 230j about axis X1, thereby driving rotating member 400j to rotate at the second speed.

[0223] As shown in Figure 50, when the line is to be fully released, the knob 210j can be rotated in the release direction R2. The knob 210j rotates relative to the rotating transmission member 260j, and the rotating transmission member 260j rises to the rising position, driving the transmission gear 255j to rise, so that its stop surface drives the coupling member 240j back to the engagement position, and allows the outer clamping portion 2552j of the transmission gear 255j to engage with the inner convex tooth 272j.

[0224] Furthermore, the user may rotate the knob 210j in the tightening direction R1. At this time, the knob 210j may rotate relative to the rotating transmission member 260j, causing the rotating transmission member 260j to gradually descend to the descending position.

[0225] Please refer to Figures 51 and 52, wherein Figure 51 illustrates an exploded view of a cinch fastening device 100k according to an eleventh embodiment of the present invention, and Figure 52 illustrates another exploded view of the cinch fastening device 100k of the eleventh embodiment of Figure 51. The cinch fastening device 100k includes a knob 210k, a rotation transmission member 260k, a transmission gear 255k, a coupling member 240k, a gear member 230k, and a plurality of planetary gears 253k.

[0226] The knob 210 k may include two driving protrusions 215 k and a knob stud 219 k . Each driving protrusion 215 k is protruded from the inner circumference, and the knob stud 219 k is protruded from the top surface.

[0227] The rotary transmission member 260k is located within the knob 210k and includes a rotary disc 263k, three rotary transmission arms 261k, and a rotary hole 266k. The rotary transmission arms 261k protrude from the rotary disc 263k and extend circumferentially. The rotary hole 266k penetrates the rotary disc 263k and engages with the transmission gear 255k.

[0228] The transmission gear 255k includes a gear body (not shown), three outer clamping parts 2552k and a transmission screw hole 2554k. The transmission screw hole 2554k is located at the upper half of the gear body and is screwed into the knob stud 219k.

[0229] Please refer to Figures 53, 54, and 55, along with Figures 51 and 52. Figure 53 illustrates a side cross-sectional schematic diagram of the tie-line fastening device 100k of the eleventh embodiment shown in Figure 51. Figure 54 illustrates another side cross-sectional schematic diagram of the tie-line fastening device 100k of the eleventh embodiment shown in Figure 51. Figure 55 illustrates yet another side cross-sectional schematic diagram of the tie-line fastening device 100k of the eleventh embodiment shown in Figure 51. As shown in Figures 51 to 53, the transmission gear 255k is not raised but is in the driving position. Rotating the knob 210k in the tightening direction R1 drives the rotating transmission member 260k to rotate, coupling the transmission gear 255k with the rotating transmission member 260k. The coupling member 240k is in the engaged position and interlocks with the gear member 230k. At this time, rotating the knob 210k in the tightening direction R1 drives the rotating transmission member 260k, which in turn drives the transmission gear 255k and the coupling member 240k, driving the gear member 230k and the planetary gear 253k simultaneously, thereby driving the rotating member 400k to rotate at the first speed. As shown in Figure 54, when the line tension increases, the coupling member 240k is unable to drive the gear member 230k and is pushed downward to the disengaged position. At this time, if the knob 210k is continuously rotated in the tightening direction R1, because the coupling member 240k is unable to drive the gear member 230k, the planetary gear 253k rotates relative to the gear member 230k about the axis X1, thereby driving the rotating member 400k to rotate at the second speed.

[0230] As shown in FIG55 , when the tie line is to be fully released, the knob 210k can be rotated in the release direction R2. At this time, due to the structural relationship between the transmission screw hole 2554k and the knob stud 219k, the transmission gear 255k rises to the disengaged position, and the rotating member 400k can rotate freely without restriction.

[0231] Furthermore, the user may rotate the knob 210 k in the tightening direction R1 , and the knob 210 k may rotate relative to the rotation transmission member 260 k , causing the rotation transmission member 260 k to gradually descend to the driving position.

[0232] Please refer to Figures 56, 57, and 58, wherein Figure 56 illustrates an exploded view of a tether securing device 100m according to a twelfth embodiment of the present invention, Figure 57 illustrates another exploded view of the tether securing device 100m of the twelfth embodiment shown in Figure 56, and Figure 58 illustrates a side cross-sectional view of the twelfth embodiment shown in Figure 56. The tether securing device 100m includes a rotation drive mechanism (not shown in the twelfth embodiment) and a rotating member 400m.

[0233] The rotary drive mechanism includes a gear member 230m, a plurality of planetary gears 253m, and a knob 210m. The planetary gears 253m are housed within the gear member 230m. The knob 210m is operably coupled to the planetary gears 253m and includes an outer cover 216m and an inner cover 217m. The inner cover 217m is operably coupled to the rotating member 400m. When the tension applied to the rotating member 400m is greater than or equal to a tension threshold, rotating the outer cover 216m in the tightening direction R1 fails to drive the inner cover 217m to rotate the rotating member 400m.

[0234] Please refer to Figure 59 in conjunction with Figures 56 to 58. Figure 59 illustrates a schematic top cross-sectional view of the cord fastening device 100m of the twelfth embodiment of Figure 58 taken along section line 59-59. The outer cover 216m may include a torque projection 2161m, which projects downwardly from the outer cover top surface of the outer cover 216m. The inner cover 217m is housed within the outer cover 216m and includes an inner cover top surface corresponding to the outer cover top surface. The inner cover 217m also includes a torque ring 2171m, which projects from the inner cover top surface toward the outer cover top surface. The remaining structure of the inner cover 217m is identical to that of the knob 210i of the ninth embodiment, and details are not repeated here. As shown in Figure 59, when the inner cover 217m and outer cover 216m are assembled, the torque projection 2161m projects into the torque ring 2171m.

[0235] The torsion convex portion 2161m may include multiple convex arcs, and the torsion ring 2171m may include multiple concave arcs corresponding to the aforementioned multiple convex arcs. The number of convex arcs and concave arcs can be six, but is not limited to this. The torsion ring 2171m may also include multiple convex segments, with the convex segments connecting between the two concave arcs.

[0236] When the pulling force applied to the rotating part 400m is relatively small, rotating the outer cover 216m allows the convex arc of the torsion protrusion 2161m to push the concave arc of the torsion ring 2171m, thereby driving the inner cover 217m to rotate; conversely, when the pulling force applied to the rotating part 400m is greater than or equal to the pulling force threshold, rotating the outer cover 216m allows the torsion protrusion 2161m to push the convex section to deform, and from the original concave arc to another adjacent concave arc, and the inner cover 217m cannot be linked to, thereby avoiding damage or injury caused by continuing to tighten the tie line when the tie line tension is too large.

[0237] Please refer to Figures 60 and 61 together with Figures 56 to 59, wherein Figure 60 illustrates another side cross-sectional schematic diagram of the tie-line fastening device 100m of the twelfth embodiment of Figure 56, and Figure 61 illustrates yet another side cross-sectional schematic diagram of the tie-line fastening device 100m of the twelfth embodiment of Figure 56. As shown in Figure 58, the rotary transmission member 260m is not raised but is in the lowered position, the transmission gear 255m is coupled to the rotary transmission member 260m, the coupling member 240m is in the engaged position, the limiting teeth of the limiting portion 249m are engaged with the coupling teeth 235m, the coupling portion 241m corresponds to the convex teeth 232m, and the engaging claw 247m is located above the inner convex ring of the gear member 230m. At this time, rotating the outer cover 216m in the tightening direction R1 allows the torque protrusion 2161m to push the torque ring 2171m, thereby driving the inner cover 217m to rotate, thereby driving the rotating transmission member 260m to rotate, linking the transmission gear 255m and the coupling member 240m, driving the gear member 230m and the planetary gear 253m to move simultaneously, and driving the rotating member 400m to rotate at the first speed.

[0238] As shown in Figure 60, when the tether tension increases, the load on coupling member 240m exceeds the tolerance threshold, and coupling portion 241m is unable to drive gear member 230m, causing coupling member 240m to move downward to the disengaged position, and the stopper teeth disengage from engagement teeth 235m. At this point, if knob 210m is continuously rotated in tightening direction R1, because coupling member 240m is unable to drive gear member 230m, planetary gear 253m rotates relative to gear member 230m about axis X1, thereby driving rotatable member 400m to rotate at the second speed.

[0239] As shown in FIG61, when the line is to be fully released, the knob 210m can be rotated in the release direction R2 to rotate the knob 210m relative to the rotating transmission member 260m, so that the rotating transmission member 260m rises to the rising position, and the stop surface of the transmission gear 255m also drives the coupling member 240m back to the engaged position.

[0240] Furthermore, the user may rotate the knob 210m in the tightening direction R1. At this time, the knob 210m may rotate relative to the rotating transmission member 260m, causing the rotating transmission member 260m to gradually descend to the descending position.

[0241] Please refer to Figures 62, 63, and 64, wherein Figure 62 illustrates an exploded view of a tether fastening device 100n according to a thirteenth embodiment of the present invention, Figure 63 illustrates another exploded view of the tether fastening device 100n of the thirteenth embodiment of Figure 62, and Figure 64 illustrates a side cross-sectional view of the tether fastening device 100n of the thirteenth embodiment of Figure 62. The tether fastening device 100n includes a housing (not shown in the thirteenth embodiment), a rotation drive mechanism (not shown in the thirteenth embodiment), and a rotating member 400n.

[0242] The housing includes a plurality of engaging teeth 312n. The rotation drive mechanism includes a ratchet arm 222n, a plurality of protruding teeth 232n, a plurality of inner ring teeth 231n, a plurality of planetary gears 253n, a coupling portion 241n, and a knob 210n. The ratchet arm 222n selectively engages with the engaging teeth 312n. The protruding teeth 232n and the inner ring teeth 231n rotate in conjunction with the ratchet arm 222n. The planetary gears 253n correspond to the inner ring teeth 231n, and the coupling portion 241n corresponds to the protruding teeth 232n. The knob 210n is operably coupled to the planetary gears 253n and includes a deflection protrusion 2162n corresponding to the ratchet arm 222n. When the knob 210n is rotated in the tightening direction R1 and the coupling portion 241n is engaged with the convex tooth 232n, the planetary gear 253n and the inner ring tooth 231n do not rotate relative to each other but rotate together around the axis X1, driving the rotating member 400n to rotate at a first speed; when the knob 210n is rotated in the tightening direction R1 and the coupling portion 241n is continuously separated from the convex tooth 232n, the planetary gear 253n and the inner ring tooth 231n rotate relative to each other, and only the planetary gear 253n rotates around the axis X1, driving the rotating member 400n to rotate at a second speed; when the knob 210n is rotated in the release direction R2, the deflection protrusion 2162n deflects the ratchet arm 222n, the ratchet arm 222n disengages from the engaging tooth 312n, and a small section of the tie line is released.

[0243] The rotation drive mechanism includes a gear element 230n, a plurality of planetary gears 253n, a transmission gear 255n, and a knob 210n. The planetary gears 253n are housed within the gear element 230n, and the transmission gear 255n is selectively coupled to the planetary gears 253n. The knob 210n selectively drives the transmission gear 255n. When the tension applied to the rotating member 400n is greater than or equal to a tension threshold, rotating the knob 210n in the tightening direction R1 will not activate the transmission gear 255n, which in turn activates the planetary gears 253n to drive the rotating member 400n.

[0244] Please refer to FIG. 65 , along with FIG. 62 to FIG. 64 , wherein FIG. 65 illustrates a top cross-sectional view of the tether fastening device 100n according to the thirteenth embodiment of FIG. 64 , taken along the cut plane line 65-65. The knob 210n is operably coupled to the planetary gear 253n and includes an outer cover 216n and an inner cover 217n. The outer cover 216n may include three deflection protrusions 2162n projecting downwardly from the top surface of the outer cover 216n. The inner cover 217n may include three through-holes 2172n extending through the top surface of the inner cover and corresponding to the three deflection protrusions 2162n. Therefore, when the inner cover 217n is assembled with the outer cover 216n, each deflection protrusion 2162n may pass through a respective through-hole 2172n and protrude into the inner cover 217n.

[0245] The inner cover 217n may further include a transmission protrusion 2173n protruding downward from the top surface of the inner cover. Three through-holes 2172n surround the transmission protrusion 2173n. The transmission protrusion 2173n can be inserted into the torque hole 2555n of the transmission gear 255n. The transmission protrusion 2173n and the torque hole 2555n can both be shaped like a plum blossom, where the transmission protrusion 2173n includes multiple convex arcs, while the torque hole 2555n includes multiple concave arcs and convex segments. When the pulling force applied to the rotating part 400n is relatively small, the rotating outer cover 216n can drive the inner cover 217n to link the transmission protrusion 2173n, so that its convex arc pushes the concave arc of the torque hole 2555n, thereby driving the transmission gear 255n to rotate; on the contrary, when the pulling force applied to the rotating part 400n is greater than or equal to the pulling force threshold, the transmission protrusion 2173n will push the convex section of the torque hole 2555n to deform, and enter another adjacent concave arc from the original concave arc, and will be unable to drive the transmission gear 255n, thereby avoiding damage or injury caused by continuing to tighten the line when the line tension is too large.

[0246] The rotational drive mechanism may include a gear member 230n and a detent member 220n. The gear member 230n may include a cylindrical wall 233n, an upper ring plate (not shown), and a plurality of engaging teeth 235n. The upper ring plate is connected to the upper end of the cylindrical wall 233n. Inner ring teeth 231n are disposed within the cylindrical wall 233n. Raised teeth 232n are disposed within the cylindrical wall 233n and above the inner ring teeth 231n. The engaging teeth 235n may protrude downward from the upper ring plate. The detent member 220n is located above the gear member 230n and may include a detent ring 221n and three ratchet arms 222n. The detent ring 221n is protruding from the upper ring plate. Each ratchet arm 222n protrudes from the outer annular surface of the detent ring 221n and extends along the circumference of the detent ring 221n. When the knob 210n is covered on the detent member 220n, each deflection protrusion 2162n can protrude into the gap between each ratchet arm 222n and the plurality of engaging teeth 312n.

[0247] The coupling member 240n may include a coupling ring body 242n, multiple coupling portions 241n, three engaging claws 247n, three limiting blocks 248n, and three limiting portions 249n. Each limiting portion 249n radially protrudes from the coupling ring body 242n and extends upward from the lower edge of the coupling ring body 242n. Each limiting portion 249n includes multiple limiting teeth (not shown). Each coupling portion 241n extends from one side of each limiting portion 249n along the circumference of the coupling ring body 242n. Three engaging claws 247n protrude from the upper end of the coupling ring body 242n. Each limiting block 248n protrudes from the inner annular surface of the coupling ring body 242n and is located below each engaging claw 247n.

[0248] The cord fastening device 100n may further include a connecting unit 500n connecting the knob 210n and the rotating member 400n. The connecting unit 500n may include a positioning shaft 510n and a screw 520n. The positioning shaft 510n passes through the rotating member 400n from bottom to top and includes a shoulder that abuts against the transmission gear 255n. The screw 520n is interlocked downwardly with the positioning shaft 510n through the outer cover 216n.

[0249] Please refer to Figures 66 and 67 together with Figures 62 to 65, wherein Figure 66 illustrates another side cross-sectional view of the cinch cord fastening device 100n of the thirteenth embodiment shown in Figure 62, and Figure 67 illustrates yet another side cross-sectional view of the cinch cord fastening device 100n of the thirteenth embodiment shown in Figure 62. As shown in Figure 64, the coupling member 240n is in the engaged position, with the limiting teeth of the limiting portion 249n engaged with the engaging teeth 235n, the coupling portion 241n corresponding to the protruding teeth 232n, and the engaging claw 247n located above the inner protruding ring of the detent member 220n. At this time, rotating the outer cover 216n in the tightening direction R1 can drive the inner cover 217n to link the transmission protrusion 2173n, so that its convex arc pushes the concave arc of the torque hole 2555n, thereby driving the inner cover 217n to rotate. The transmission protrusion 2173n then links the transmission gear 255n and the coupling member 240n, thereby driving the gear member 230n and the planetary gear 253n to move simultaneously, so that the rotating member 400n is driven to rotate at the first speed.

[0250] If the user wants to fine-tune the line tension, he can turn the knob 210n in the release direction R2, as shown in Figure 65. Since each deflection protrusion 2162n is located in the gap between each ratchet arm 222n and the shell, and the cross-section of the deflection protrusion 2162n is roughly triangular, the deflection protrusion 2162n can push the ratchet arm 222n toward the braking ring 221n when it moves in the release direction R2, thereby separating the ratchet arm 222n from the engaging tooth 312n, thereby releasing a small section of the line.

[0251] As shown in Figure 66, when the line tension increases, the load on coupling member 240n exceeds the tolerance threshold, and coupling portion 241n is unable to drive gear member 230n, causing coupling member 240n to move downward to the disengaged position. Engaging claw 247n is positioned below the inner convex ring of detent member 220n, and the limiting teeth disengage from engaging teeth 235n. At this point, if knob 210n is continuously rotated in the tightening direction R1, since coupling member 240n is unable to drive gear member 230n, planetary gear 253n rotates relative to gear member 230n about axis X1, thereby driving rotatable member 400n at the second speed.

[0252] As shown in Figure 67, when the line is to be fully released, the knob 210n can be pulled up along the axis X1 to move the knob 210n from the first position to the second position. The transmission gear 255n is pushed up by the shoulder of the positioning shaft 510n and moves up in conjunction. The limit block 248n is pushed up by the stop surface of the transmission gear 255n, and the coupling member 240n is driven back to the engaged position.

[0253] Furthermore, the user may press down the knob 210n again, and the knob 210n may return to the first position.

[0254] Please refer to Figures 68, 69, and 70. Figure 68 is a perspective view of a tether fastening device 100p according to a fourteenth embodiment of the present invention. Figure 69 is an exploded view of the tether fastening device 100p of the fourteenth embodiment shown in Figure 68. Figure 70 is another exploded view of the tether fastening device 100p of the fourteenth embodiment shown in Figure 68. The tether fastening device 100p includes a housing 300p, a rotation drive mechanism, and a rotating member 400p.

[0255] The rotation drive mechanism includes a gear 230p, a plurality of planetary gears 253p, a coupling 240p, and a knob 210p. The gear 230p is located within the housing 300p and includes a plurality of inner ring teeth 231p. The plurality of planetary gears 253p are located within the gear 230p and correspond to the plurality of inner ring teeth 231p. The coupling 240p is located within the housing 300p and switches between an engaged position and a disengaged position. The knob 210p covers the housing 300p and is operably coupled to the plurality of planetary gears 253p. The rotating member 400p is located within the housing 300p and is operably coupled to the rotation drive mechanism. Among them, when the knob 210p rotates in the tightening direction R1 and the coupling member 240p is located in the engagement position limiting the housing 300p and the gear member 230p, the aforementioned multiple planetary gears 253p rotate relative to the gear member 230p in the tightening direction R1, so that the rotating member 400p rotates in the tightening direction R1 at a first speed; when the knob 210p rotates in the tightening direction R1 and the coupling member 240p switches to the separation position without restricting the gear member 230p, the aforementioned multiple planetary gears 253p rotate together with the gear member 230p around the axis X1, so that the rotating member 400p rotates in the tightening direction R1 at a second speed.

[0256] Specifically, the housing 300p may include a shell 310p and a base 320p, with the base 320p being detachably connected to the shell 310p. The shell 310p may include a shell annular wall 311p, a plurality of engaging teeth 312p, a partition wall 315p, and a plurality of stop teeth 314p. The engaging teeth 312p are disposed around the shell annular wall 311p and protrude radially inward. The partition wall 315p is located above the engaging teeth 312p and protrudes radially inward to subdivide the upper chamber into a first zone and a second zone. The stop teeth 314p protrude downward from the partition wall 315p.

[0257] The gear element 230p is accommodated in the first area and includes an upper ring body 237p, a lower ring body 238p, and two protrusions 239p. The upper ring body 237p and the lower ring body 238p are connected to each other, the inner ring gear 231p is disposed within the upper ring body 237p, and the lower ring body 238p includes an axial hole, and the two protrusions 239p are symmetrically disposed within the axial hole.

[0258] The coupling member 240p, housed in the second region, may include a barrel 245p, a disk 246p, multiple coupling portions 241p, two engaging claws 247p, and multiple coupling teeth 249p. The disk 246p is connected to the lower end of the barrel 245p. The diameter of the barrel 245p is smaller than that of the disk 246p, and the barrel 245p is configured to engage with the axial hole of the lower ring 238p. The coupling portion 241p has a tooth structure and protrudes from the disk 246p, corresponding to the stop teeth 314p. The two engaging claws 247p protrude from the outer wall (not shown) of the barrel 245p and can be coupled to the two protrusions 239p. The coupling teeth 249p protrude from the bottom of the disk 246p.

[0259] The rotary drive mechanism may further include a detent member 220p located below the coupling member 240p and above the rotating member 400p. The detent member 220p includes a detent ring 221p, three ratchet arms 222p, and a plurality of recessed portions 223p. Each ratchet arm 222p protrudes from the detent ring 221p and extends circumferentially around the detent ring 221p. The recessed portions 223p are located on the detent ring 221p and correspond to the coupling teeth 249p.

[0260] The rotation drive mechanism may further include a sun gear 252p, which is disposed through the detent member 220p, the coupling member 240p, and the gear member 230p and includes a plurality of upper sun teeth 2521p and a plurality of lower sun teeth 2522p. The upper sun teeth 2521p engage with the planetary gears 253p, while the lower sun teeth 2522p engage with the detent member 220p and the rotating member 400p.

[0261] Please refer to Figures 71, 72, and 73 together with Figures 69 to 70, wherein Figure 71 is a side cross-sectional schematic diagram of the cinch fastening device 100p of the fourteenth embodiment shown in Figure 68, Figure 72 is another side cross-sectional schematic diagram of the cinch fastening device 100p of the fourteenth embodiment shown in Figure 68, and Figure 73 is yet another side cross-sectional schematic diagram of the cinch fastening device 100p of the fourteenth embodiment shown in Figure 68. As shown in Figures 69 to 71, when the knob 210p is not pulled up and is in the first position, the coupling member 240p is in the engaged position and engages with the stop tooth 314p, the coupling tooth 249p does not protrude into the recessed portion 223p, and the two engaging claws 247p are respectively located above the two protrusions 239p of the gear member 230p, the gear member 230p cannot rotate relative to the housing 310p. Therefore, when the knob 210p is rotated in the tightening direction R1, the planetary gears 253p rotate relative to the inner ring gear 231p about the axis X1. Because the planetary gears 253p have smaller diameters, their rotation speed is faster than that of the knob 210p, driving the sun gear 252p to rotate faster in the tightening direction R1. At this time, the ratchet arm 222p continuously disengages the engaging tooth 312p, allowing the rotating member 400p to tighten the tie line at the first speed.

[0262] As shown in Figure 72, when the tension in the tether increases, the planetary gears 253p attempt to rotate the gear member 230p in the tightening direction R1. When the tension exceeds a threshold, the coupling member 240p is pushed downward along the axis X1, causing the coupling member 240p to move to the disengaged position and disengage from the stop tooth 314p. The coupling tooth 249p protrudes into the recess 223p, and the two engaging claws 247p are respectively located below the two protrusions 239p of the gear member 230p. At this time, if the knob 210p is continuously rotated in the tightening direction R1, each planetary gear 253p will drive the gear member 230p to rotate about the axis X1. Therefore, each rotation of the knob 210p will drive the rotating member 400p to rotate one rotation, allowing the rotating member 400p to tighten the tether at the second speed.

[0263] As shown in Figure 73, when the knob 210p is pulled up to the second position along the axis X1, it can drive the sun gear 252p to move upward, so that the lower sun gear 2522p disengages from the rotating member 400p, so that the rotating member 400p can be allowed to rotate freely to release the line, and at this time the coupling member 240p can also be linked back to the engaged position.

[0264] Please refer to Figures 74, 75, and 76, wherein Figure 74 illustrates an exploded view of a cord-fastening device 100q according to a fifteenth embodiment of the present invention, Figure 75 illustrates another exploded view of the cord-fastening device 100q of the fifteenth embodiment of Figure 74, and Figure 76 illustrates a side cross-sectional view of the cord-fastening device 100q of the fifteenth embodiment of Figure 74. The cord-fastening device 100q includes a housing 300q, a rotation drive mechanism (not shown in the fifteenth embodiment), and a rotating member 400q.

[0265] The housing 300q may further include a stopper tooth 314q. The rotation drive mechanism may include a plurality of inner ring teeth 231q, a coupling portion 241q, planetary gears 253q, and a knob 210q. The inner ring teeth 231q are located within the housing 300q. The coupling portion 241q rotates in conjunction with the inner ring teeth 231q and can selectively engage with the stopper tooth 314q. The planetary gears 253q correspond to the inner ring teeth 231q. When the knob 210q rotates in the tightening direction R1 and the coupling portion 241q engages with the stop tooth 314q to limit the inner ring tooth 231q, the aforementioned multiple planetary gears 253q rotate relative to the gear part 230q in the tightening direction R1, so that the rotating part 400q rotates in the tightening direction R1 at a first speed; when the knob 210q rotates in the tightening direction R1 and the coupling portion 241q separates from the stop tooth 314q without limiting the inner ring tooth 231q, the aforementioned multiple planetary gears 253q rotate together with the gear part 230q around the axis X1, so that the rotating part 400q rotates in the tightening direction R1 at a second speed.

[0266] The housing 300q may include a housing 310q and a base 320q. The housing 310q may include a housing annular wall 311q, a partition wall 315q, a plurality of limiting protrusions 316q, a plurality of engaging teeth 312q, a top flange 317q, an annular flange 318q, and stop teeth 314q. The limiting protrusions 316q are projecting from the inner side of the housing annular wall 311q and above the partition wall 315q. The engaging teeth 312q are circumferentially disposed on the housing annular wall 311q, projecting radially inward and positioned below the partition wall 315q. The stop teeth 314q project downward from the partition wall 315q. The top flange 317q radially protrudes from the upper open end of the housing annular wall 311q, the annular flange 318q radially protrudes from the outside of the housing annular wall 311q and is located below the top flange 317q, and the radial thickness of the annular flange 318q is smaller than the radial thickness of the top flange 317q.

[0267] The rotary drive mechanism may further include a gear member 230q, which includes an inner ring gear 231q, an upper ring body 237q, two protrusions 239q, an axial hole (not labeled), and an annular groove (not labeled). The inner ring gear 231q is annularly disposed within the upper ring body 237q, the two protrusions 239q are symmetrically disposed within the axial hole, and the annular groove is radially recessed outside the upper ring body 237q. When the gear member 230q is placed within the housing 310q, the limiting protrusion 316q can protrude into the annular groove.

[0268] The knob 210q may include a knob latch 2174q. When the knob 210q is covered on the housing 310q, the knob latch 2174q may be located below the annular flange 318q.

[0269] Specifically, knob 210q may further include an outer cover 216q and an inner cover 217q. The outer cover 216q may include a torque projection 2161q, while the inner cover 217q further includes a torque ring 2171q. When the inner cover 217q and outer cover 216q are assembled, the torque projection 2161q protrudes into the torque ring 2171q. The inner cover 217q may further include a knob latch 2174q and an inner cover sidewall. The knob latch 2174q protrudes from the lower edge of the inner cover sidewall.

[0270] The rotation drive mechanism may further include a detent 220q and a coupling 240q, wherein the coupling 240q includes a coupling portion 241q. The structures of the detent 220q and the coupling 240q are similar to those of the fourteenth embodiment, and details are omitted for brevity.

[0271] Please refer to Figures 77 and 78 together with Figures 74 to 76, wherein Figure 77 illustrates another side cross-sectional view of the cinch fastening device 100q of the fifteenth embodiment shown in Figure 74, and Figure 78 illustrates yet another side cross-sectional view of the cinch fastening device 100q of the fifteenth embodiment shown in Figure 74. As shown in Figures 74 to 76, when the knob 210q is not pulled up and is in the first position, the coupling member 240q is in the engaged position and engages with the stop tooth 314q, and the gear member 230q cannot rotate relative to the housing 310q. Therefore, when the knob 210q is rotated in the tightening direction R1, the torque protrusion 2161q can push the torque ring 2171q, thereby driving the inner cover 217q to rotate. Each planetary gear 253q can rotate around the axis X1 relative to the inner ring gear 231q, thereby driving the sun gear 252q to rotate in the tightening direction R1 at a faster speed, so that the rotating part 400q can tighten the line at the first speed.

[0272] As shown in Figure 77, when the tension of the tie line increases, the planetary gear 253q will try to rotate the gear part 230q in the tightening direction R1, and when the tension exceeds the threshold, the coupling part 240q will be pushed down along the axis X1, so the coupling part 240q will move to the separation position and separate from the stop tooth 314q. If the knob 210q is continuously rotated in the tightening direction R1, each planetary gear 253q will drive the gear part 230q to rotate around the axis X1, so that the rotating part 400q can tighten the tie line at the second speed.

[0273] As shown in Figure 78, when the knob 210q is pulled up to the second position along the axis X1, the knob clamping portion 2174q is moved to the bottom of the top flange 317q through the annular flange 318q and contacts the top flange 317q, and the sun gear 252q moves upward, so that the lower sun gear (not marked in the 15th embodiment) disengages from the rotating member 400q, so that the rotating member 400q can be allowed to rotate freely to release the line, and at this time the coupling member 240q can also be linked back to the engaged position.

[0274] Please refer to Figures 79, 80, and 81. Figure 79 illustrates an exploded view of a tether securing device 100r according to a sixteenth embodiment of the present invention. Figure 80 illustrates another exploded view of the tether securing device 100r of the sixteenth embodiment of Figure 79. Figure 81 illustrates a side cross-sectional view of the tether securing device 100r of the sixteenth embodiment of Figure 79. The tether securing device 100r includes a housing (not shown in the sixteenth embodiment), a rotation drive mechanism (not shown in the sixteenth embodiment), and a rotating member 400r. The rotation drive mechanism includes a knob 210r, a rotation transmission member 260r, a lifting cylinder 270r, a gear member 230r, a coupling member 240r, a detent member 220r, and a plurality of planetary gears 253r.

[0275] The knob 210r may include two driving protrusions 215r and a knob stud 219r. Each driving protrusion 215r is protruded from the inner circumference, and the knob stud 219r is protruded from the top surface.

[0276] The rotation transmission member 260r is coupled to the knob 210r and includes a rotating disc 263r, a rotation transmission arm 261r, multiple pivots 262r, a transmission boss 265r, and multiple rotating teeth 264r. The rotation transmission arm 261r protrudes from the rotating disc 263r and extends along the circumference of the rotating disc 263r. The pivot 262r and the transmission boss 265r protrude downward from the rotating disc 263r, and the pivot 262r surrounds the transmission boss 265r. The rotating teeth 264r are located distally from the transmission boss 265r.

[0277] The lifting cylinder 270r is inserted into the center hole of the connecting cylinder 281r and includes a screw hole 271r that is screwed into the knob stud 219r.

[0278] The actuator 220r comprises a locking ring 221r, a locking cylinder 225r, multiple ratchet arms 222r, multiple recesses 223r, and multiple connecting teeth 226r. The locking ring 221r ​​is connected to the lower end of the locking cylinder 225r. The ratchet arms 222r protrude from the locking ring 221r ​​and extend circumferentially around the locking ring 221r. The recesses 223r are located in the gap between the locking cylinder 225r and the locking ring 221r. The connecting teeth 226r are located at the upper end of the locking cylinder 225r.

[0279] A plurality of planetary gears 253r are located within the gear member 230r and correspond to the inner ring gears 231r. The actuator cylinder 225r extends through the coupling member 240r and protrudes into the gear member 230r to engage with the gear member 230r. The structure of the gear member 230r and the coupling member 240r is similar to that of the gear member 230q and the coupling member 240q in the fifteenth embodiment, and the details are not repeated here.

[0280] The rotary drive mechanism may further include a connecting member 280r, which is disposed through the detent member 220r and includes a connecting cylindrical portion 281r, a plurality of abutting portions 282r, a plurality of upper teeth 283r, and a plurality of lower teeth 284r. The connecting cylindrical portion 281r is inserted into the detent member 220r and is rotationally fixed to the detent hole of the detent member 220r. The abutting portions 282r protrude from the outer side of the connecting cylindrical portion 281r and extend upward from the lower edge. The upper teeth 283r are disposed at the upper end of the connecting cylindrical portion 281r, and the lower teeth 284r are disposed at the lower end of the connecting cylindrical portion 281r and engage with the rotating member 400r.

[0281] The tie-line fastening device 100r may further include a connecting unit 500r, which includes a positioning shaft 510r, a screw 530r and a screw (not shown). The positioning shaft 510r passes through the rotating member 400r and the connecting member 280r. The screw 530r is limited to the lifting cylinder 270r and inserted into the positioning shaft 510r. The screw can lock the positioning shaft 510r and the screw 530r.

[0282] Please refer to Figures 82 and 83, along with Figures 79 to 81. Figure 82 illustrates another side cross-sectional view of the tie line fastening device 100r according to the sixteenth embodiment of Figure 79, and Figure 83 illustrates yet another side cross-sectional view of the tie line fastening device 100r according to the sixteenth embodiment of Figure 79. As shown in Figures 79 to 81, the coupling member 240r is in the engaged position and engages with the stop teeth 314r of the housing 310r, preventing the gear member 230r from rotating relative to the housing 310r. At this time, rotating the knob 210r in the tightening direction R1 drives the protrusion 215r to push the rotating transmission arm 261r, which in turn links the lifting cylinder 270r and the connecting member 280r, driving the detent member 220r to rotate in the tightening direction R1, causing the ratchet arm 222r to deflect without affecting rotation. Simultaneously, the connecting member 280r drives the rotating member 400r, via the lower teeth 284r, to tighten the tie line at a first speed.

[0283] As shown in Figure 82, when the tension in the tether increases, the planetary gears 253r attempt to rotate the gear element 230r in the release direction R2. When the tension exceeds a threshold, the coupling element 240r is pushed downward along the axis X1, causing the coupling element 240r to move to the disengaged position and disengage from the stop tooth 314r. This causes the coupling tooth 249r of the coupling element 240r to protrude into the recess 223r, while still being linked to the detent element 220r but not constraining the gear element 230r. If the knob 210r is continuously rotated in the tightening direction R1, the planetary gears 253r drive the gear element 230r to rotate about the axis X1, causing the rotating element 400r to tighten the tether at a second speed.

[0284] When the user releases the knob 210r, the ratchet arm 222r engages with the engaging tooth 312r of the housing 310r in the release direction R2. The connecting member 280r is also limited by being engaged with the detent 220r, preventing the rotating member 400r from rotating in the release direction R2, thereby tightening the tie line.

[0285] As shown in Figure 83, if the user wants to release the line, he can rotate the knob 210r in the release direction R2. At this time, due to the engagement relationship between the ratchet arm 222r and the engaging tooth 312r, the connecting member 280r, the lifting cylinder 270r and the rotating transmission member 260r cannot rotate in the release direction R2, so the driving protrusion 215r can be separated from the rotating member 400r, and the lifting cylinder 270r rises due to the structural relationship between the screw hole 271r and the knob stud 219r. The linked connection unit 500r drives the link member 280r to rise, and the lower tooth 284r is separated from the rotating member 400r, and the rotating member 400r can rotate freely. At the same time, the connecting member 280r rises relative to the detent member 220r, causing the upper tooth 283r to engage with the rotating tooth 264r of the rotating transmission member 260r, and the pushing portion 282r rises from the pushing hole of the detent member 220r to push the coupling tooth 249r that is not aligned with the recessed portion 223r, thereby pushing the coupling member 240r back to the engaged position.

[0286] When the user wants to tighten the tie line again, he can rotate the knob 210r in the tightening direction R1. Since the upper teeth 283r are engaged with the rotating transmission member 260r, the connecting member 280r is limited by the rotating transmission member 260r. The knob 210r rotates in the tightening direction R1 relative to the rotating transmission member 260r, causing the lifting cylinder 270r, the connecting member 280r and the connecting unit 500r to descend together.

[0287] Please refer to Figures 84 and 85 , wherein Figure 84 illustrates a side cross-sectional schematic diagram of a cinch fastening device 100s according to a seventeenth embodiment of the present invention, and Figure 85 illustrates another side cross-sectional schematic diagram of the cinch fastening device 100s of the seventeenth embodiment of Figure 84 . The structure of the cinch fastening device 100s is similar to that of the cinch fastening device 100q of the fifteenth embodiment, except that when the knob 210s is pulled up along the axis X1 from the first position to the second position, the knob engaging portion 2174s is relocated below the top flange 317s via the annular flange 318s, but is still separated from the top flange 317s by a gap.

[0288] Please refer to Figures 86 and 87 , wherein Figure 86 illustrates an exploded schematic diagram of a tether securing device 100t according to an eighteenth embodiment of the present invention, and Figure 87 illustrates another exploded schematic diagram of the tether securing device 100t of Figure 86 , the eighteenth embodiment. The tether securing device 100t includes a housing 300t, a rotating member 400t, a detent 600t, and a knob 200t. The housing 300t includes a shell 310t and a base 320t.

The detent 600t is disposed within the housing 300t and is operably coupled to the rotating member 400t. The knob 200t is mounted on the housing 310t and operably coupled to the rotating member 400t. The knob 200t includes a knob latch 220t that couples to the top flange 317t to assemble the knob 200t and the housing 310t. The knob 200t can be moved along the axis X1 between a first position and a second position. When the knob 200t is in the first position, a first gap is defined between the top flange 317t and the knob latch 220t. Rotating the knob 200t in the tightening direction R1 causes the rotating member 400t to tighten the tie line. When the knob 200t is pulled to the second position, a second gap is defined between the top flange 317t and the knob latch 220t, allowing the rotating member 400t to freely release the tie line. This second gap is smaller than the first gap and is non-zero.

The knob 200t can further include three knob clamping arms 210t, which protrude downward from the top surface of the knob 200t and engage the detent 600t.

[0294] The tie-line fastening device 100t may further include a connecting unit 500t, which includes a screw 520t, a blocking ring 530t and a sleeve 540t. The blocking ring 530t is located in the through space of the rotating member 400t, the sleeve 540t is inserted downward and limited to the detent member 600t, and the screw 520t passes through the blocking ring 530t from bottom to top to lock into the sleeve 540t.

[0295] During assembly, the knob 200t and the actuator 600t are first assembled together using the knob clamping arm 210t. The housing 310t and the knob 200t are then assembled together. The rotating member 400t is then placed into the housing 310t with the lower open end facing upward. The components other than the base 320t are then assembled together using the connecting unit 500t. Finally, the base 320t is joined to the housing 310t.

[0296] As shown in Figure 88 , the knob 200t is not yet pulled up. The detent arm 630t of the detent member 600t is positioned below the stopper protrusion 490t of the rotating member 400t. The detent teeth engage with the rotating drive teeth. Rotating the knob 200t in the tightening direction R1 rotates the rotating member 400t to tighten the tie line. When the knob 200t is not rotated, the ratchet arm 620t engages with the engaging teeth 312t in the release direction R2, preventing the tie line from being released. As shown in Figure 89 , when the knob 200t is pulled up to the second position, the knob arm 210t drives the detent member 600t upward along the axis X1. The detent arm 630t of the detent member 600t is repositioned above the stopper protrusion 490t of the rotating member 400t, and the detent teeth disengage from the rotating drive teeth. This allows the rotating member 400t to release the tie line in the release direction R2 without restriction.
