Variable-Screwdriver

When using the traditional screwdriver, we usually can’t choose the appropriate length we need. That caused many problems. The Variable-Screwdriver can solve the problem easily. Just rotate the top knob then fold the iron rod from the long side to the short side and lock it. So you can choose the length of you like to use it.
