The specific embodiment

The structure and the preparation method that describe the embodiment of the invention with reference to the accompanying drawings in detail are as follows:

Fig. 2 is the oblique view of the key chain of developing according to the present invention.At first this key chain 10 possesses the grade strip of being formed with random length and width 11, and the two ends of extending its grade strip 11 are until generating identical a pair of possess first and second suspension member key element 12, the processed element 21 of 12a; Reverse grade strip 11 more in the other direction, until generating overlapping a pair of first and second suspension

member key element

12,12a.

Extend first and second suspension member key element 12 of the two ends generation of key chain 10

grade strips

11,12a according to the windup-degree that tightens position 13 (about 90 degree), keeps the equitant state of first and second suspension member key element.That is, when the windup-degree of grade strip 11 is spent greater than 90, according to the windup-degree that tightens position 13, the one side of equitant first and second suspension member key element will be kept the state that closely pastes mutually.So the key that is suspended on the key chain 10 can not pulled out easily.The manufacture craft of the key chain 10 of this structure is as follows:
