Abstract
An electric tool and a method for fastening a threaded member by using it, the electric tool has a torque output system and a control system configured to, according to a fastening level selected by a user, invoke a corresponding data to drive the motor to enable it to output with designated single-time impact quantity and impact times.
Claims20
An electric tool, comprising:
- an output shaft for driving a threaded member;
- an impact transmission assembly for driving the output shaft intermittently;
- a motor for driving the impact transmission assembly;
- and
- a control system which drives the motor according to a total impact quantity data which corresponds to a fastening level selected by a user;
- wherein the total impact quantity data comprises a single-time impact quantity data and an impact times data and wherein the control system comprises a data storage module for storing the total impact quantity data, the single-time impact quantity data and the impact times data.
A method for fastening a threaded member by using an electric tool comprising an output shaft for driving a threaded member, an impact transmission assembly for driving the output shaft intermittently, a motor for driving the impact transmission assembly, and a control system which drives the motor according to a total impact quantity data which corresponds to a fastening level selected by a user, wherein the total impact quantity data comprises a single-time impact quantity data and an impact times data and wherein the control system comprises a data storage module for storing the total impact quantity data, the single-time impact quantity data and the impact times data, the method comprising:
- causing the control system to invoke a total impact quantity data according to a fastening level selected by the user;
- and
- causing the control system to invoke a combination of a set of single-time impact quantity data and impact times data according to the total impact quantity data to drive the motor and enable the motor to generate an output with a designated single-time impact quantity and impact times.
