This video features an innovative adjustable wrench invention. The prototype as shown is a ready-to-market model. Its unique technology and design can be easily transferred to any size as you might design.

Unique features include:
1) one-thumb pressing stepless and instant adjusting mechanism; 
2) efficient anti-slip system provides no damage to the workpiece;
3) the more stress made on the handle/jaws, the more force is aroused onto the surface of the workpiece;
