Kind Code:
A3
Abstract:
This is an invention that permits the construction of tools that are especially efficient, convenient, and economical. The tools in this invention are adjustable wrenches, a ring wrench, an open end wrench and a pipe wrench, intended for loosening and tightening bolts having heads of various sizes, while they accurately grip the head of the bolt. The wrench is adjusted to the bolt immediately in a continuous movement. We refer to closed and open ended wrenches for suitable bolts, in metric or inch sizes, or a combination of these, as well as a pipe wrench. The current invention offers a wrench that requires only one hand to be used for loosening and tightening any bolt, smoothly and precisely, and without damaging the bolt itself. Adjustment to the size of the head of the bolt is done in a smooth and continuous movement, at the end of which the wrench is locked precisely on the size of the bolt.
