The overall structure diagram of lacing device after assembly is as shown in figure 11.Motion mode by controlling lid 27 can be with At least two gears are provided.Such as: it pushes lid 27 and rotor 21 is driven to move down, the retaining ring of rotor accommodating cavity bottom is made to be resisted against angle Prominent lower edge, the i.e. position of the first gear, internal tooth are connected with outer pawl, and the lid may only be along the direction of tightening tape Rotation；Pull-up lid 27 drives rotor 21 to move up, and is resisted against the retaining ring of rotor accommodating cavity bottom in limiting slot, i.e. the second gear Position, the internal tooth separates connection with outer pawl, the lid can respectively along loosen frenulum and tighten the direction of tape from By rotating, attached drawing is not shown.

Embodiment 3

The lacing device according to described in Examples 1 and 2 can be used not only for tying the shoelace, and can be also used for being clothes, cap Son, suitcase and other items, and packing frenulum that can be also used for object etc..

The utility model discloses a kind of lacing devices, are intended merely to description conveniently, the rotor described in utility model is The definition of article for rotation, stator is the definition of stationary object, but stator and rotor are the definition to relative motion object, anti-mistake It is also to set up to define, does not refer to that some object is certain static or rotates.It in certain embodiments can opposite fortune between object It is dynamic, it is also applied for the definition of rotor and stator.

The above is only the preferred embodiment of the utility model only, is to combine specific preferred embodiment to this reality With novel made further description, and it cannot be said that the specific implementation of the utility model is only limited to these instructions.It is all It is practical new to should be included in this for made any modifications, equivalent replacements, and improvements etc. within the spirit and principles of the utility model Within the protection scope of type.
