[0002] Since ordinary data cables are generally long and inconvenient to carry, if they are placed directly on a table or in a bag, they are easy to get entangled with themselves and other items, causing inconvenience to the user. For this reason, people have invented various retractable data cables, which are equipped with a spring (spiral spring) in the main part to cooperate with a wheel core to reel in the data cable, so as to achieve the effects of being more compact and anti-entanglement. At present, such retractable data cables on the market are usually directly pulled out by hand for charging, and are generally released quickly by pulling again, so that the data cable retracts into the shell under the elastic force of the spring, thereby achieving the effect of telescopic use.
