What's the difference between a ratchet screwdriver and an ordinary screwdriver? Is it really that good to use?
Each has his merits! The ratchet screwdriver has a corner, not a straight handle screw in narrow space. But the ratchet screw handle is a lever, and the force acting on the end of the screwdriver is much larger than that of the straight shank screwdriver, which means that it saves a lot of effort.
First of all, I must tell you, it really works.The ratchet effect, the screwdriver can only rotate in one direction, makes you screw, forward (some ratchet can adjust the forward and reverse rotation), can tighten the screws, when the direction of rotation, the screw does not rotate along with the handle, just to reverse rotation, so it is very convenient for operation, but also save effort.This process is not easy to describe. You can find a screwdriver with a ratchet wheel, especially for high strength repeated screw action.
