20110180288	Torque system of power tool - A torque system of a power tool includes a combination of a first body and a second body, in which a toothed ring is assembled; and a mode selecting assembly, a torque adjusting module and control pins disposed on the second body. The torque system further includes restricting mechanisms formed on the second body, and the control pins are respectively disposed in the restricting mechanisms. One side of the control pin has a stopper block, and the restricting mechanism includes a first stopper, a second stopper and a through hole. When the control pin is driven to rotate and the stopper block faces the first stopper or the through hole, the object of switching each operation mode is achieved.	07-28-2011

20080303533	Cable testing device and testing method thereof - A cable testing device of the present invention can test sheltering performance of a cable which has a central wire, a shelter wrapped around the central wire and an exterior cover wrapped around the shelter. One end of the central wire and two ends of the shelter are earthed. The cable testing device includes a network testing device and a metal tube. The network testing device has an input which is connected to the other end of the cable and an output. The metal tube incloses the cable to be tested, one end of the metal tube is connected to the output of the network testing device, the other end is earthed. As a result, an electromagnetic field is formed in the interior of metal tube, thereby, the sheltering performance of the shelter of the cable can be tested directly before the whole cable product being assembled.	12-11-2008
