Efficient Wrench / wrench

Efficient Wrench
Efficient Wrench

When using the wrench, we are limited by the narrow width. Thus we have to re-locate the screw, which wastes time and mechanical work. This concept is to design an efficient wrench. Once a screw is located, it is unnecessary to relocate until it is tighted up.
