A system for scheduling packets to be transmitted is provided. The system includes a soft delay bound calculator module and a frame determination module. The soft delay bound calculator module calculates a soft delay bound for a non-real-time packet based on a packet size of the non-real-time packet and a minimum reserved traffic rate of a channel. The frame determination module determines whether a real-time packet must be transmitted at a current frame according to a delay bound, a transmission time, and a possible retransmission time thereof, and whether a non-real-time packet must be transmitted at a current frame according to a soft delay bound, a transmission time, and a possible retransmission time thereof. Thus, it is possible to improve the performance of the system while keeping the QoS thereof in a mixed service environment.

A hand tool includes a first part including a head and a shank. Three first holes are defined in the shank and each receive a first stop and a first spring therein. A second hole is defined in shank and located at an axis different from an axis of the first holes, a second stop and a second spring are received in the second hole. A second part is movably mounted to the shank and includes a positioning hole with which one of the first stop is removably engaged. The second stop is slidably engaged with a groove in the second part. A third part is mounted to the second part and includes button which is pushed to remove the first stop from the position hole so that the second part and the third part can be moved relative to the shank.
