Connecting lines for line segments. In particular, the conductive circuit of the present invention is in a flat shape, which makes it more convenient and tidy to retract and return to the retracting device.

The rolling device of the present utility model includes two rolling mechanisms with the same structure, which are the first rolling mechanism and the second rolling mechanism. The first rolling mechanism is used to connect and stretch the first line segment; The mechanism is used to connect and stretch the second line segment.
