Title: Fixing Structure for Rope

Description:
FIELD OF THE INVENTION 
     The present invent relates to a fixing structure which is applied to adjust and position a rope for fixing an object. 
     BACKGROUND OF THE INVENTION 
     A conventional fixing structure for a rope is used to adjust and position the rope for fixing an object. 
     The rope has two ends, and each or two ends are tied to form one or two tied portions, but each tied portion lessens easily, so the rope cannot be fixed securely. To solve such a problem, an improved fixing structure has been developed. For example, the fixing structure contains a seat, a resilient element, and a pressing member. The seat has a receiving groove defined therein and a through hole passing through the receiving groove. The resilient element is mounted in the receiving groove by ways of the pressing member, and the pressing member has a retaining fringe defined on a bottom end thereof, such that the pressing member is fixed in the receiving groove so that the retaining fringe retains with the through hole. The pressing member also has a chamber so that when it is pushed by the resilient element to move outwardly, the retaining fringe is fixed, and when the pressing member is forced, the chamber of the pressing member aligns with the through hole, and when the pressing member is unforced, it is pushed outwardly. It is to be noted that after pressing the pressing member, the chamber aligns with the through hole so as to insert the rope into the fixing structure via the chamber, thus moving the fixing structure to any desired portion on the rope. After the pressing member is unforced, a shear force produces between the pressing member and the seat, hence the rope is fixed between the through hole and the chamber. However, the rope cannot be fixed securely. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary object of the present invention is to provide a fixing structure which is applied to adjust and position a rope for fixing an object. 
     To obtain the above objectives, a fixing structure contains: a body including a connecting unit and a guiding unit coupled with one end of the connecting unit. 
     The connecting unit has a through hole defined therein so as to insert one of two inserting ends of the rope. 
     The guiding unit has an extension member and at least one support arm for matching with the extension member, wherein a defining space is open and is defined between the extension member and the at least one support arm so as to position a tied portion on the other of the two inserting ends of the rope, such that one of the two inserting ends is fixed in the connecting unit, and the tied portion is fitted and engaged with the limiting end of the defining space, thus positioning the rope.
