  • Torque wrench
    Patent number: 8607675
    Abstract: A torque wrench includes a driving head, a hollow handle, compression unit, an adjustment unit, an index unit and a display unit. The driving head and the handle are pivotably connected to each other. The compression unit has a resilient member and an end piece which contacts the driving head. The adjustment unit adjusts the length of the resilient member to set the torque of the wrench. The index unit has a first index and a second index, both of which are moved with the movement of the adjustment unit. The movement of the first index is detected by the display unit and transferred into digits to display the value of the torque. The second index is cooperated with the marks of the scale member to display the value of the torque.
