The invention discloses a low-torsion multifunctional electromechanical wrench device, and relates to the technical field of wrenches. The low-torsion multifunctional electromechanical wrench device comprises a handle, a torque device and a shaping and buckling device. The torque device comprises a V-shaped connection frame, a master control gear and a motor. The middle of the connection frame is connected with the front end of the handle. Arc-shaped positioning shells are connected to the left side and the right side of the front portion of the connection frame. The side edges of the positioning shells are inwards concave and are matched with the edges of the master control gear. Inserting connection holes are uniformly formed in a guide groove. A control lock matched with the inserting connection holes are slidably connected into a through hole. The shaping and buckling device comprises a shell fixedly connected with the inner wall of an installation hole, and vibration motors. An annular elastic bag is fixed into the shell in a sleeved mode and filled with shear thickening liquid. The outer side of the elastic bag is fixedly connected with the interior of the shell. The multiple vibration motors are annularly and uniformly distributed inside the elastic bag. The low-torsion multifunctional electromechanical wrench device has the beneficial effects that the specification adjusting speed is high, adaptability is high, operation is easy, and time and effort are saved.
