Patent number: 8434983Abstract: An exemplary locking assembly includes a locking member and a sleeve. The locking member includes a locking portion, a neck portion, and a head portion. One end of the neck portion is connected to the head portion, and another end of the neck portion is connected to the locking portion. An outer diameter of the locking portion is larger than that of the neck portion. An outer diameter of the locking portion is larger than that of the neck portion. The sleeve defines a through hole therein for holding and guiding the locking member. The through hole includes a first part. The sleeve further includes a restricting portion extending out from an inner surface of the through hole adjoining the first part of the through hole. After locking portion of the locking member passes through the restricting portion of the sleeve, the restricting portion blocks the locking portion from sliding out of the sleeve.Type: GrantFiled: March 10, 2011Date of Patent: May 7, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Hsuan-Chen Chen
