A garment, such as the tetherless knob described above.

The garment may particularly comprise shoes, clothing, gloves, helmets, etc.

Specifically, the assembly process of the tether-free knob is as follows: the elastic element 50 is plugged into the groove from the large opening of the convex groove 121 of the chassis 10 and then pushed to the side with the small opening; then the button 40 is inserted into the large opening of the embossed groove 121 of the chassis 10 to be in contact with the elastic member 50; then the rope body 60 is penetrated into the chassis 10 from the through hole 11 of the chassis 10, passes through the rope penetrating hole 31 of the receiving column 30, is wound on the receiving column 30 and is knotted and fixed; finally, the screw cap 20 is pressed from top to bottom, so that the snap strip 22 on the screw cap 20 and the snap ring 14 of the chassis 10 are mutually buckled, and the movement of the screw cap 20 in the vertical direction is limited, i.e. the installation is completed.

Further, the use process of the tether-free knob is as follows: as shown in FIG. 7, when the button 40 is not pushed, the helical teeth 421 of the button 40 limit the cap 20 to rotate only to one side, the direction of rotation is determined according to the orientation of the external teeth 21 of the cap 20, as shown in FIG. 6, the external teeth 21 incline counterclockwise, when the cap 20 rotates counterclockwise, i.e., rotates in the direction of inclination of the external teeth 21, the angular teeth 421 of the button 40 are locked at the root of the external teeth 21 of the cap 20, at this time, the angular teeth 421 of the button 40 limit the cap 20 to rotate counterclockwise, i.e., limit the cap 20 to rotate in the direction of inclination of the external teeth 21. When the screw cap 20 is rotated clockwise, i.e., rotated against the inclination direction of the external teeth 21, the contact point between the external teeth 21 and the helical teeth 421 is not forced, and the inclined surface of the external teeth 21 of the screw cap 20 pushes the helical teeth 421 of the button 40 to move downward, so that the helical teeth 421 of the button 40 and the external teeth 21 of the screw cap 20 are separated from each other. The rotary cap 20 is rotated to drive the receiving column 30 to rotate and wind the rope body 60, thereby tightening the rope body 60.

When the button 40 is pushed downward, as shown in fig. 8, that is, when the button 40 is pushed toward the elastic member 50, the button 40 moves toward the small opening of the embossed groove 121, so that the inclined teeth 421 of the button 40 are separated from the outer teeth 21 of the cap 20, the cap 20 is released, and the cap 20 rotates by pulling the string bodies 60 at both ends to rotate the storage column 30 counterclockwise, thereby releasing the string bodies 60.

It is noted that, in this specification, relational terms such as first and second, and the like are used solely to distinguish one entity from another entity without necessarily requiring or implying any actual such relationship or order between such entities.

The principles and embodiments of the present application are explained herein using specific examples, which are provided only to help understand the method and the core idea of the present application. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present application without departing from the principle of the present application, and such improvements and modifications also fall within the scope of the claims of the present application.
