Abstract
A hand tool includes a fixture having an adjustable working end and an opposing handle. The handle is rotated to the fixture. A transmission couples the handle to the adjustable working end, whereby rotation of the handle urges corresponding adjustment of the adjustable working end. The working end includes an end section, and a wrench insert rotated to the end section, or co-acting movable jaws mounted to the end section.
Claims18
A hand tool, comprising:
- a fixture having an adjustable working end and an opposing handle rotated to the fixture;
- and
- a transmission coupling the handle to the adjustable working end, whereby rotation of the handle urges corresponding adjustment of the adjustable working end.
A hand tool, comprising:
- a handle rotated to a fixture having an end section;
- a wrench insert rotated to the end section;
- a driven member rotated to the end section;
- the driven member is coupled the wrench insert, whereby rotation of the driven member urges corresponding rotation of the wrench insert;
- and
- the handle is coupled to the driven member, whereby rotation of the handle urges corresponding rotation of the driven member.
The hand tool according to claim 38, further comprising a shaft coupling the handle to the driven member, whereby rotation of the handle urges corresponding rotation of the shaft, which, in turn, urges the corresponding rotation of the driven member.
A hand tool, comprising:
- a handle rotated to a fixture having an end section;
- co-acting movable jaws mounted to the end section;
- a driven member rotated to the end section;
- the driven member is coupled the co-acting movable jaws, whereby rotation of the driven member urges corresponding movement of the co-acting movable jaws;
