Correspondingly, the pawl ring of the sleeve includes the annular pedestal, one or more pawl arms are attached to the inner periphery of the annular pedestal and having one or more internal pawls formed thereon, and the internal pawls and the external tooth on the upper cover can engage or disengage. The end faces of the gear tooth and the winding slot are provided with the corresponding second meshing tooth.

(57) When the lacing device is in use, after threading the lace, upper cover 26 is forcibly pressed down, and a click sound is heard, second meshing tooth 264 on upper cover 26 and first meshing tooth 233 on winding slot 23 engage (after engagement, the upper cover can only rotate in the tightening direction and cannot rotate in the loosening direction). When upper cover 26 is rotated in the tightening direction, a crisp click sound can be heard. At this moment, external pawl 253 and internal teeth 2531 engage, and second meshing tooth 264 and first meshing tooth 233 engage. Upper cover 26 drives winding slot 23 to rotate in the tightening direction, and the lace is wound around winding slot 23. The object to be tightened is slowly tightened by the lace until the tightness is proper. If the lace is tied too tight, upper cover 26 can be pulled up so that second meshing tooth 264 of the upper cover is out of contact with first meshing tooth 233 of the winding slot. At this time, the tight lace will drive the winding slot to reverse and loosen the object. Upper cover 26 is pressed down again and the previous tightening action is repeated to adjust the object to be tightened to a proper tightness.

(84) First, the lace extends from lacing device 15 to the first side and passes through the first guide member, and secondly, the lace extends to the first side and passes through the second guide member, again, the lace extends to the second side and passes through the third guide member, then, the lace extends to the second side and passes through the fourth guide, then, the lace extends to the first side and passes through the fifth guide member, then, the lace extends to the first side and passes through the sixth guide member, again, the lace extends to the second side and passes through the seventh guide member, then, the lace extends to the second side and passes through the eighth guide member, and finally, the lace returns to lacing device 15.

(85) In addition, as shown in FIG. 23, lacing device 15 is fixed to the first side of the tightening edge, and the number of guide member 16 is one in total, guide member 16 is fixed to the second side of the tightening edge. First, lace 10 extends from lacing device 15 to the second side and passes through the first guide member, and finally returns to lacing device 15 on the first side.

(86) In order to further improve the stability of the lacing device, adhesive straps can be additionally arranged on both sides of the tightening edge, and the adhesive straps can have one side fixed or can have both sides movable.

(87) Additionally, the number of the guide members of this embodiment is not limited to one, and one or more guide members can implement the present invention.

(88) The above is merely preferred embodiments of the present invention and a further detailed description of the present invention combined with the specific preferred embodiment, and cannot be considered that the specific embodiments of the present invention is merely limited to these descriptions. Any modifications equivalents and improvements without departing from the spirit and principle of the present invention shall be considered as falling within the scope of the present invention.
