• a main body, defining an axial direction;
• a driving portion, disposed on an end of the main body, when the driving portion receives a torque which is greater than a torque setting value, the driving portion is idling;
• a positioning member, fixedly disposed in the main body;
• a torque adjusting assembly, including an abutting member and a mandrel, the abutting member being movable along the axial direction to adjust the torque setting value, the mandrel being disposed in the main body, rotatable about the axial direction and screwed to the abutting member, the mandrel being disposed through the positioning member and rotatable about the axial direction;
• a tripping assembly, including an elastic abutting member and a plurality of notches arranged circumferentially, the elastic abutting member being disposed on the mandrel, the plurality of notches being disposed on the positioning member, the elastic abutting member being abutted against one of the plurality of notches normally, when the mandrel rotates relative to the positioning member, the elastic abutting member trips among the plurality of notches;
• wherein the mandrel includes a threaded section and a cylindrical shaft section, the elastic abutting member is disposed on the cylindrical shaft section, the mandrel has a flange between the cylindrical shaft section and the threaded section, and the flange is axially blocked between the positioning member and the abutting member.
