As shown in the figure, 'USB transmission line 12 is the point of the construction of the connector 10, the signal connector η and the line of view of the line, /, the USB connector 10 and the USB with the USB interface, such as the computer host 'Connected, and the signal connector = number of consecutive ages depends on the material, the camera or t «line retracting device 12 is connected to the USB connector 10 and the signal connection 6 200926549 between the 11 'mainly contains the shell The body 121, the reel 122, the balls 123, the scroll spring 124, and the cable 125. The housing 121 is formed by combining the first housing 1211 and the second housing 1212, and a sleeve 1213 is protruded from the inner surface of the first housing 1211 for pivoting the reel 122. In addition, • the shaft column The 1213 is provided with a slot 1214' for engaging with the partial scroll spring 124, so that the scroll coil spring 124 is fixed between the first outer casing 1211 and the reel 122. In addition, the inner surface of the second housing 1212 has a limiting slot ^1215 for the ball 123 to be movably received therein. The reel 122 is used for the cable 125 to be wound thereon, and the surface of the reel 122 has a groove 1221, an oblique guide groove 1222 and a curved notch 1223, wherein the oblique guide groove 1222 is adjacent to the groove 1221. The arcuate notch 1223 is adjacent to the oblique guide groove 1222 and adjacent to the end of the groove 1221 for restricting the sliding position of the ball 123 on the reel 122. .
