Section 726 and the first spiral part 722 rotate in proper order.The first spiral part is reached when pin 600 rotates in the counterclockwise direction
When 722, pin 600 along the first spiral part 722 radius reduce direction move, be then moved to stop track 740 rather than
Then second spiral part 724 stops at and stops on track 740.Herein, when pin 600 is moved along annular section 726, pin 600
Tend to continuously follow circular path, so that the connection track reduced to radius will not be redirected back into from circular segments 726
730.It therefore, there is no need to the stepped portion for preventing from entering connection track 730 from outside track 720.
When pin 600, which stops at, to be stopped on track 740, if slight pulling and cable release 200, pin 600 is along counterclockwise
Direction rotates, and into inner orbit 710, then continuous rotation along clockwise direction, line 200 is wound around reel 300.
Meanwhile when pin 600 stop at stop on track 740 when, if as discussed above, continuous pulls wire 200, then pin 600
It is rotated on stopping track 740 in the counterclockwise direction, into inner orbit 710, then in the counterclockwise direction via connection track 730
The continuous rotation on outside track 720 unlocks line 200 from reel 300.
