[0080] As shown in FIGS. 2, 10, and 12, in one embodiment of the present disclosure, optionally, the reel 130 comprises a reel 133 and a disk body 134 disposed at both ends of the reel 133, wherein the disk body 134 has a diameter greater than the diameter of the reel 133. The reel 133 is respectively provided with a first threading hole 1331 and a second threading hole 1332 along the direction perpendicular to the axis of reel 133. The fixing member 120 is provided with a first avoidance hole 125 and a second avoidance hole 126, wherein the first avoidance hole 125 is provided correspondingly to the first threading hole 1331, and the second avoidance hole 126 is provided correspondingly to the second threading hole 1332.

[0081] In this embodiment, one end of the cord can be sequentially passed through the first avoidance hole 125 and the first threading hole 1331 to be knotted and fixed within the reel 130, and the other end of the cord can be sequentially passed through the second avoidance hole 126 and the second threading hole 1332 to be knotted and fixed within the reel 130.

[0082] In summary, the present disclosure proposes a winding device 100, wherein the winding device 100 comprises a housing 110, a fixing member 120, a reel 130 for winding the cord, a knob 140, a connecting member 150, a limiting component 160 and a fastener 170, wherein the limiting component 160 comprises a guide member 161 and an elastic member, and the fixing member 120 is connected to the housing 110 and is provided with a through cavity 121 with openings at both ends. An elastic arm 122 is provided at one end of the fixing member 120 away from the housing 110, and a check portion 1221 is provided at the circumferential edge of the elastic arm 122. The reel 130 is rotatable in the axial direction and disposed in the through cavity 121, and a toggle portion 131 is provided at one end of the reel 130 away from the housing 110. The side of the knob 140 facing the fixing member 120 is provided with a first clamping member 142 and a linkage portion 141 that cooperates with the check portion 1221. The connecting member 150 is connected to the end of the reel 130 away from the housing 110, wherein the outer periphery of the connecting member 150 is provided with a second clamping member 151 matching with the first clamping member 142, and a stepped hole 152 is provided in the inner periphery of the connecting member 150. An end of the guide member 161 close to the housing 110 is provided with a cooperation portion 1611 that matches with the toggle portion 131, and multiple guide grooves 1521 are circumferentially defined and formed along the inner wall of the hole with the largest aperture of the stepped hole 152. A guide clamping structure 1522 is formed between two adjacent guide grooves 1521. The elastic member abuts between the fixing member 120 and the knob 140. The guide member 161 is movably passed through the stepped hole 152, clamping slider 1612 is provided along the circumferential direction of the guide member 161, and the fastener 170 is passed through the guide member 161 to connect to the knob 140.

[0083] In the process of use, for example, when tightening the cord, it is only necessary to press the knob 140 once to squeeze and drive the guide member 161 to move synchronously to make the clamping slider 1612 slide out of the guide groove 1521, and to make the cooperation portion 1611 abut against the toggle portion 131, so as to rotate the guide member 161 in the stepped hole 152 under the action of the toggle portion 131, thereby making the clamping slider 1612 snapped with the guide clamping structure 1522. The first clamping member 142 is snapped with the second clamping member 151. At this time, the elastic member is compressed, and the linkage portion 141 is snapped with the check portion 1221, such that the knob 140 can only rotate in one of the clockwise direction or the counterclockwise direction, for example, the knob 140 can only rotate in the clockwise direction. In this way, the knob 140 can drive the reel 130 to rotate to tighten the cord. If it is necessary to release the cord, on the basis of the first pressing of the knob 140, the knob 140 is pressed again, and the cooperation portion 1611 abuts against the toggle portion 131, so as to rotate the guide member 161 in the stepped hole 152 under the action of the toggle portion 131. At the same time, using the reset elasticity generated by the elastic member being compressed, the clamping slider 1612 is slid from the clamping structure into the guide groove 1521, and the first clamping member 142 is separated from the second clamping member 151. At this time, the elastic member is reset, the linkage portion 141 is engaged with the check portion 1221, the reel 130 can rotate freely in the clockwise or counterclockwise direction, and the cord can be loosened from the reel 130. The cord can be tightened or loosened by sequentially cyclically operating and pressing the knob 140, that is, by pressing the knob 140, the cord can be rotated and tightened. The operation is simple and convenient, and avoids the technical difficulty in operation caused by pulling up the knob in the prior art.
