By turning the handle, one side can be pretensioned to the stop. A few millimeters are sufficient for loosening and tightening. In idle speed, the screw is adjusted by the rotation of the handle.

The fine-toothed gear (52 teeth) can also be used as a normal ratchet. Unlocking of the insert tools is done at the push of a button, with the ability to switch from right to left rotation. The handy handle is made of two-component material with screwdriver ergonomics and a square holder.
