X-Spanner / tools

X-Spanner
X-Spanner

We always encounter nuts with different sizes in our daily life, and we usually need different types of spanners.
X-spanner offers a creative way to solve this problem.It can change the size according to the different sizes of nuts.
There are six rotatable parts on this tool, which are connected to the outer ring through gear meshing.
When you turn the outer ring and change gear, these parts will rotate, and then the size of hexagon will change.
So this spanner can be effectively used in different situations.
