Patent number: 9004247Abstract: A mobile power pack includes a cover over a guide track which includes first, second, third, and fourth turning points. A sliding block defines a sliding groove to receive a ball, and the slotted ball interacts with the guide track. An elastic element is connected to the sliding block. When a cable is pulled out, the sliding block slides from the first turning point to the second turning point. When the pull on the cable is released, the elastic element restores to cause the sliding block to move until the ball reaches the third turning point, to lock the cable in position. When the cable is pulled and released, the sliding block slides until the ball reaches the fourth turning point, allowing the cable to be retracted into the body of the power pack.Type: GrantFiled: April 16, 2013Date of Patent: April 14, 2015Assignee: Zhongshan Innocloud Intellectual Property Services Co., Ltd.Inventor: Man-Zhong Wang
