Publication number: 20180133872Abstract: An electric power tool includes a wireless module, a controller, a stage-selection module, a trigger switch, a driver and a driving motor. The method for operating the electric power tool includes steps of receiving a wireless signal from the outside via the wireless module, wherein the wireless signal includes a plurality of control parameters; storing the control parameters into the memory; upon receiving a stage-selection signal, extracting a control parameter in accordance with the stage-selection signal from the memory; upon receiving a triggering signal, outputting a control signal to the driver so as to drive the driving motor, wherein the control signal is output based on a torque value of at least one control parameter which is corresponding to the stage-selection signal. It allows a user to change the settings of the electric power tool via wireless communication, thereby increasing the flexibility of using the electric power tool.Type: ApplicationFiled: November 3, 2017Publication date: May 17, 2018Applicant: MOBILETRON ELECTRONICS CO., LTD.Inventor: KIM Y.C.

Publication number: 20110203819Abstract: A power tool includes a detecting member mounted in an output end of a housing, and a to-be-detected member mounted in a driver. When the driver is assembled with the output end of the housing, the detecting member will detect the to-be-detected member and transmit a signal to a torque adjustment unit disposed in the housing so as to enable the torque adjustment unit to automatically adjust the torque applied to the driver to reach a predetermined value, thereby preventing damage to the driver.Type: ApplicationFiled: April 22, 2010Publication date: August 25, 2011Applicant: MOBILETRON ELECTRONICS CO., LTD.Inventors: Kim Y.C. Tsai, Cheng-I Teng, Chia-Chang Yeh
