Torque wrenches are widely used in mechanical assembly or repair applications, for screw-on components on machinery or parts, such as nuts, for locking or dismounting operations, however, in some high-precision machines (eg : aeronautical mechanism components), each screw lock component has a certain procedure and proper tension operation requirements. However, if the manual output torque is inadvertently operated, the screw lock component or the screw hole may be damaged or the operation of the machine itself may be damaged. Function and precision, but the known torque wrench does not have the REAL TIME detection and display torque function when the force is applied. Therefore, the user cannot understand the actual torque value, but the user must Experience with the conventional torque wrench may result in improper torque output for human operation.

The separation technique of the hand tool sensing and the data display, that is, the hand tool and the receiving device are separated from each other, so that the receiving device can wirelessly receive the data sensed by the sensor when the hand tool is actuated, and borrow the data data. Wireless transmission to another display or processing device simultaneously receives and displays data data and analyzes the data content.

Still another object of the present invention is to provide an alternative torque detecting device and a torque detecting module system thereof that can be widely attached and detached to various hand tools. Specifically, the torque detecting device of the present invention is provided with a joint portion, which is adapted to be connected to the driving heads of various tool components, such as to improve the sharing and measuring the convenience of the applicator.

Furthermore, the wireless transmission function of the present invention has the effect of the torque value detected by the torque wrench, and provides an accurate display of the torque value and an alarm operation, and further, through the torque processing circuit and the control receiver. The wireless two-way transmission function, and the torque value of at least one set of torque wrenches is equal to the supply line transmission function, in other words, the torque values of the torque wrench bodies can be wirelessly transmitted through the torque processing circuits in the plurality of torque wrench bodies. Go to a control receiver, and then connect the control receiver to at least one remote electronic device such as a personal computer (PC), a personal data assistant (σDA), a notebook computer, etc. for application and Management, and can achieve the true and precise management of the torque wrench output torque output operation, and further enhance its industrial use value and economic benefits.
