Smart Torque wrench with an adjustable wrench head or a swappable socket style head

A Smart Torque Wrench with an Adjustable Wrench Head is disclosed. The invention integrates a motorized electronically adjustable wrench head with a jaw opening range of 8–46 mm, sub-millimetre jaw position encoding, contactless fastener size detection, and a jaw locking mechanism providing fixed-socket-equivalent rigidity during torque application; a multi-axis torque and angle sensing system comprising full Wheatstone bridge strain gauge transducers with ±1% accuracy over 0–1,000 Nm and a MEMS 6-DOF IMU; an AI-assisted fastening guidance and anomaly detection engine for tightening strategy optimization, real-time torque-angle curve analysis, cross-threading and thread-stripping detection, and joint stiffness classification; a multimodal feedback system including a colour TFT display, haptic actuator, audible alert, RGB LED array, and voice output; a wireless communication module supporting BLE 5.0 and Wi-Fi for per-joint tightening traceability record transmission to a cloud quality management platform; and a power management system with LiPo battery, USB-C fast charging, piezoelectric energy harvesting, and Qi wireless charging. The invention eliminates the need for separate socket inventories, provides full per-joint tightening traceability, and enables AI-driven fastening quality assurance in a single universal handheld precision tool platform.
