Amazing Screwdriver / Screwdriver

There are quite a few types of screws and screwdrivers nowadays. In practical applications, it is often required to find a suitable screwdriver which matches a specific screw head or size. Now we've created an integrated screwdriver, which hydraulically pushes an array of carbon fiber tubes to mate any screw head. For screws or bolts within a certain size range, they can now be driven by a single screwdriver. The mechanism of extending or retracting each tube is just like that of moving small syringes back and forth.
