Reversible cable tie

Abstract

A reversible cable tie includes a belt, a guide portion and a constraint base. The belt includes a first end, a second end and a plurality of constraint structures. The guide portion and the constraint base are disposed on the first end and the second of the belt. The constraint base includes a hollow portion, an opening structure, a hook and a handle. The belt passes through the hollow portion. The opening structure is disposed on an external surface of the hollow portion. The hook is movably disposed inside the hollow portion and exposed via the opening structure. A first end of the hook is resiliently connected to a first wall of the opening structure. A second end of the hook buckles the constraint structure, so as to constrain a movement of the belt relative to the constraint base. The handle is disposed on the second end of the hook.

1 . A reversible cable tie comprising:
 a belt, the belt comprising a first end, a second end and a plurality of constraint structures, the constraint structures being disposed between the first end and the second end;   a guide portion disposed on the first end of the belt; and   a constraint base disposed on the second end of the belt, the constraint base comprising:
 a hollow portion, the belt passing through the hollow portion; 
 an opening structure disposed on an external surface of the hollow portion; 
 a hook movably disposed inside the hollow portion and exposed via the opening structure, a first end of the hook being resiliently connected to a first wall of the opening structure, a second end of the hook buckling one of the plurality of constraint structures so as to constrain a movement of the belt relative to the constraint base, wherein a wedged protrusion is disposed on the hook, the wedged protrusion comprises a contact surface and a support surface, the contact surface is connected to the second end of the hook, the support surface is connected between the contact surface and the first end of the hook; and 
 a handle disposed on the second end of the hook, a gap being formed between the handle and a second wall of the opening structure opposite to the first wall. 
   
     
     
         2 . The reversible cable tie of  claim 1 , wherein the hook does not protrude from the external surface of the hollow portion when an external force is not applied to the hook. 
     
     
         3 . (canceled) 
     
     
         4 . The reversible cable tie of  claim 1 , wherein the opening structure further comprises a third wall and a fourth wall different from the first wall and the second wall, intervals are formed between the third wall and a lateral side of the hook, and the fourth wall and the other lateral side of the hook. 
     
     
         5 . The reversible cable tie of  claim 1 , wherein each constraint structure comprises a supporting surface and a blocking surface, the support surface and the contact surface of the wedged protrusion respectively contact against the supporting surface and the blocking surface when an external force is not applied to the hook. 
     
     
         6 . The reversible cable tie of  claim 5 , wherein a normal vector of the contact surface of the wedged protrusion is substantially parallel to a moving direction of the belt relative to the constraint base when an external force is not applied to the hook. 
     
     
         7 . The reversible cable tie of  claim 6 , wherein a normal vector of the blocking surface of the constraint structure is substantially parallel to the normal vector of the contact surface of the wedged protrusion. 
     
     
         8 . The reversible cable tie of  claim 5 , wherein resilient deformation of the second end of the hook is substantially greater than a height of the blocking surface.
