Electric-tool-torque control system and force-multiplier structure

A force-multiplier structure assembled with a torque tester and an electric tool, wherein the torque tester is configured to measure a torque of the force-multiplier structure, the force-multiplier structure comprising:

• a gear set arranged inside the force-multiplier structure;
• a force-output end exposed at one end of the force-multiplier structure and geared and assembled with the gear set;
• a force-input end exposed at the other end of the force-multiplier structure and geared and assembled with the gear set;
• a signal transmission unit arranged inside the force-multiplier structure;
• and
• a storage unit arranged inside the force-multiplier structure and electrically connected to the signal transmission unit,
• wherein the signal transmission unit receives a test data which is detected and transmitted by the torque tester;
• the storage unit stores the test data,
• wherein the torque tester comprises a torque testing circuit, a detection shaft, and a communication module;
• the detection shaft receives the torque from the force-multiplier structure, and the torque testing circuit detects the torque transmitted through the detection shaft and calculates the test data;
• the torque testing circuit is electrically connected to the detection shaft and the communication module;
• the one end of the force-multiplier structure is assembled onto the detection shaft, so that the signal transmission unit is connected with the communication module;
• wherein the electric tool at least comprises a force-output terminal, a control circuit, and a signal transmission module;
• the signal transmission module is electrically connected to the control circuit;
• the force-output terminal of the electric tool is assembled with the force-input end of the force-multiplier structure, so that the signal transmission unit is electrically connected to the signal transmission module.
