  • Patent number: 11958172
    Abstract: A torque tool includes multiple bits, a handle, a pointer and a scale ring. Each of the bits includes a colored area. In use, the handle is connected to a selected one of the bits. The handle is operable to set multiple maximum values of torque transferable to the bit from the handle corresponding to the colored areas of the bits. The pointer is formed on the handle. The scale ring includes multiple colored areas corresponding to the colored areas of the bits. The scale ring is rotated around the handle as the handle is operated to set the maximum values of torque, thereby aligning the pointer with one of the colored areas of the scale ring corresponding to the colored area of a selected one of the bits.

  • Publication number: 20240100662
    Abstract: A torque wrench includes a wrench body, a deformable rod, a torque adjustment mechanism, a switch and an alarm. The wrench body includes a working section and a gripping section. Two ends of the deformable rod are fixed to the working section and the gripping section respectively, and a middle section is formed in-between. The torque adjustment mechanism is installed in the gripping section and includes a knob and an abutting member. The knob adjusts the abutting member to be proximate to or away from the middle section. The switch is disposed between the middle section and the torque adjustment mechanism. The alarm is electrically connected to the switch, and the middle section is in a bending deformation toward the abutting member, when load of the working section is greater than a set torque, to touch the switch and trigger the alarm to generate a warning signal.
