Patent ID: 8393231

Claim:
A multifunctional torque tool detection device, comprising: at least one connection body, which has two opposite ends each forming a coupling end and an outer circumference surface forming at least one retention section; at least one tool joint bar, which has an end coupled to one of the coupling ends of the connection body and an opposite end adapted to couple to at least one tool bit that performs rotation operation to a threaded fastener; at least one signal ring assembly, which is coupled between the connection body and the tool joint bar and comprises a plurality of insulation rings and a plurality of conductor rings that alternate each other so as to allow the insulation rings to insulate and isolate the conductor rings from each other; at least one toque detection device, which is attached to the retention section of the connection body to detect a torque value induced by the rotation operation performed by the tool bit at an end of the tool joint bar and converts the torque value into a torque detection signal, the toque detection device being electrically coupled to at least one of the conductor rings of the signal ring assembly to supply the torque detection signal through the conductor ring; at least one angle sensor, which is attached to the retention section of the connection body to detect an angle value at which the tool bit at the end of the tool joint bar is set and converts the angle value into an angle detection signal, the angle sensor being electrically coupled to at least one of the conductor rings of the signal ring assembly to supply the angle detection signal through the conductor ring; a plurality of signal pick-up elements, which is respectively set in contact with the conductor rings of the signal ring assembly to pick up the torque detection signal and the angle detection signal; and at least one displaying and processing unit, which comprises a circuit for digitally displaying the torque value and the angle value and displaying of operation functions, the displaying and processing unit being electrically connected to the signal pick-up elements to receive the torque detection signal supplied from the toque detection device and the angle detection signal supplied from the angle sensor so as to display the torque value and the angle value that are induced by the rotation operation of the tool bit at an end of the tool joint bar.
