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.
Claims17
A torque tool comprising:
- multiple bits each of which comprises a colored area;
- a handle for connection to a selected one of the bits, wherein 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;
- a label supported on the handle, wherein the label comprises multiple colored areas corresponding to the colored areas of the bits and multiple numbers located in the colored areas of the label corresponding to the maximum values of torque;
- a pointer formed on the handle;
- and
- a scale ring rotated around the handle as the handle is operated to set the maximum values of torque, thereby aligning the pointer with a value on the scale ring according to one of the numbers in a corresponding one of the colored areas of the label corresponding to the colored area of a selected one of the bits.
