Abstract
An electro-mechanical torque wrench has a main body. A trip mechanism is provided in the main body. The trip mechanism includes a long rod and a short rod arranged side-by-side. A release member is connected between the long rod and the short rod. When in operation, the long rod and the short rod are subject to torque to cause flex. When the torque reaches a preset torque value, the release member is released to generate a mechanical sound and vibration to prompt a user to stop operation. The long rod is provided with at least one strain sensor, and the strain sensor is connected with a display module for sensing the amount of deformation of the long rod and transmitting sensing information to the display module, so that the display module outputs a corresponding torque value in a digital display manner.

An electro-mechanical torque wrench, comprising:
- a main body, having a hollow tubular body, one end of the tubular body being provided with a working head, another end of the tubular body being provided with a grip, wherein the tubular body has a chamber therein, an outside of the tubular body is formed with a fixing hole and at least one shaft hole that are in communication with the chamber;
- a trip mechanism, including a long rod and a short rod arranged side-by-side in the chamber, wherein one end of the long rod is connected to the working head, another end of the long rod is provided with a screw hole corresponding to the shaft hole, one end of the short rod is connected to the working head, another end of the short rod is provided with a bearing portion, a rotatable releasing member is pivotally connected to a middle section of the long rod, one side of the releasing member, close to the short rod, is provided with a pressing portion corresponding to the bearing portion, another side of the releasing member, away from the short rod, is provided with an extension portion, an elastic member is connected between the extension portion and the long rod so that the releasing member is biased by elastic force of the elastic member for enabling the pressing portion to press against the bearing portion, the trip mechanism further includes an abutment member disposed in the fixing hole, the abutment member includes an abutment rod extending toward the extension portion;
- a torque adjustment mechanism, having a screw rod passing through the shaft hole and the screw hole, one end of the screw rod extending out of the shaft hole and being provided with a rotatable knob, the knob being configured to drive rotation of the screw rod to enable the position of the long rod to be adjustable;
- and
- a digital display unit, having a display module disposed at the main body, at least one strain sensor being electrically connected to the display module and arranged on a peripheral side of the long rod for sensing the amount of deformation of the long rod and transmitting sensing information to the display module so that the display module outputs a corresponding torque value in a digital display manner.
