摘要：
A cable reel mechanism includes a main body, a cable reel, a cable, a volute spring and a switching element. The main body has a receiving room defined therein and a limiting groove. The cable reel is turnably disposed in the receiving room of the main body and has a track groove in which a ball bearing is disposed. One portion of the ball bearing engages with the limiting groove of the main body. The cable is reeled on the cable reel. The switching element is disposed on the main body and has a pressing portion which detachably presses the ball bearing. The cable reel mechanism can be switched to different operation modes via the switching element, so that users can pull then retract the cable rapidly and directly to adjust the length of the cable, therefore the operation is easier and more convenient.
