Easy Screwdriver / Tool

Easy Screwdriver
Easy Screwdriver

At first glance, you may find that this is a ordinary screwdriver. But check it out carefully, this one can save users’ strength when using it, because they turn the screws through push which is strength-saving than friction. So, it is obvious this screw driver could be more easy-to use than the ordinaries which consume the friction between users’ hands and the screwdrivers.
