The conventional fixing method of objects is to use a rope or a belt to pass through the objects, and fasten the rope or the belt to fix the objects after the objects are attached to the objects. However, the object is dropped due to the loosening of the rope or the belt, and the object cannot be fastened for a long time. Therefore, manufacturers have developed a belt-fastening device, which utilizes the teeth lattice on the belt to be fastened into the fastening portion to adjust the length of the belt so as to conform to the size of the target object and further fix the object. However, since the belt device is a disposable article and the tooth lattice cannot be separated from the engaging portion after the length of the belt device is fixed, the belt device must be cut, which is inconvenient in use.

In addition, if the target object is a frame of a bicycle, the belt device with limited engaging force cannot be firmly fastened to the frame because the bicycle is prone to shaking during riding, and the problem that objects fall off accidentally or shake and loosen easily exists.

Another fixing device has been developed by the manufacturers, which comprises a C-shaped ring body and a screw locking device, wherein the screw locking device is connected to two ends of the C-shaped ring, and the C-shaped ring body can be tightly pressed against the target object by the screw locking device to achieve the effect of fastening the object.

However, the C-ring body and the screw locking device of the fixing device have limited dimensions to be fixed, and cannot be applied to various objects having different dimensions, and the C-ring body is only applied to a tubular object.

Referring to fig. 4A and 4B, fig. 4A is a schematic cross-sectional view illustrating an operation of the fixing device 100 of fig. 1 applied to the object 110, and fig. 4B is a schematic cross-sectional view illustrating another operation of the fixing device 100 of fig. 1 applied to the object 110. When the knob 460 is moved along the axis I, the moving portion 470 is driven to move between the first position and the second position, as shown in fig. 4A, when the knob 460 is pulled up along the axis I, the moving portion 470 is driven to move up to make the engaging portion 471 engage and fix with the through hole 412 (see fig. 2B) and the through hole 421 (see fig. 2B), and the sun gear 441 is driven to move along the axis I to separate from the planetary gear 442, and at this time, the moving portion 470 is located at the first position. The ratchet arm 453 disengages from the second inner tooth 462 so that the ratchet arm 453 is not interfered with by the knob 460, that is, the ratchet arm 453 is free to rotate so that the rotation of the spool 430 is not restricted.

Therefore, when the fixing device 100 is to be fixed to the object 110, the first end 310 can be disengaged from the lip 280, and the length of the tension member 300 can be adjusted according to the size of the object 110 since the rotation of the bobbin 430 is not limited. Thus, pulling directly on the first end 310 of the tension member 300 rotates the spool 430 and releases the tension member 300, lengthening the length of the tension member 300 to an appropriate length, and then wrapping the tension member 300 around the object 110.

As shown in fig. 4B, after the tension member 300 surrounds the object 110, the first end portion 310 is hooked back to the lip 280 to connect the first end portion 310 with the main body 200, and the knob 460 is pressed down along the axis I to drive the moving portion 470 to move downward, so that the engaging portion 471 is engaged with and fixed to the through hole 270 (see fig. 2B), and the moving portion 470 is located at the second position.

When the moving part 470 is located at the second position, the ratchet arm 453 engages with the second internal teeth 462 (see fig. 2B), and the sun gear 441 engages with the planetary gear 442. As described above, the ratchet arm 453 is continuously disengaged from the second inner teeth 462 in the tightening direction a1 (see fig. 2B), so that the knob 460 and the ratchet arm 453 rotate relative to each other, when the knob 460 rotates in the tightening direction a1, the knob 460 drives the sun gear 441 to rotate, and since the detent plate 451 is fixed to the plane 260 of the main body 200, the detent plate 451 corresponds to a fixed planetary arm, the planetary gear 442 is forced to rotate the spool 430 relative to the detent plate 451, so as to retract the second end portion 320 into the spool 430 to adjust the size of the locking space 250, and the fixing member 210, the surrounding portion 330 and the arc member 220 are forced to press the object 110.

Since the ratchet arm 453 abuts against the second inner tooth 462 in the loosening direction a2 (see fig. 2B) to prevent the knob 460 and the ratchet arm 453 from rotating relative to each other, after the fixing member 210, the surrounding portion 330 and the arc member 220 are fastened to the object 110, the ratchet arm 453 prevents the tension member 300 from loosening in the loosening direction a2, so as to achieve the purpose of preventing the fastening object 110 from loosening when the fixing device 100 is fastened.

Through the structural configuration of the main body and the bundling unit, the fixing device can be tightly pressed against the target object, and the axis of the adjusting piece passes through the main body and does not pass through the target object, so that the stress of the adjusting piece for adjusting and controlling the tension piece to be retracted is more balanced, and the service life of the fixing device is prolonged.

When the adjusting piece comprises the bobbin and the knob, the length of the tension piece can be adjusted more conveniently and rapidly through the coupling and limiting effects of the bobbin and the knob, and when the main body further comprises the convex lip, the first end of the tension piece is also convenient to detach and connect with the main body.

And thirdly, the structure which allows the second end part to penetrate through the channel can enable the first end part, the main body and the surrounding part to surround to form a locking space and can be matched with the size of the target object to be tightly pressed. If a hole is arranged on the main body for the second end to penetrate through, the second end of the tension piece can be prevented from protruding outwards to influence the operation or being accidentally hooked on other objects. And through the arrangement of the tension member, the fixing device can be suitable for targets with various shapes, thereby achieving the application diversity.

And fourthly, different objects can be connected through the arrangement of the connecting unit, the weight is reduced, and the convenience of use can be increased through the connecting unit.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
