90 Screwdriver / Screwdriver

When assembling easy furniture or hang the frame, people use a screwdriver and screw. but, it is difficult to drive a screw into the wall or furniture exactly 90 degrees. You sometimes find crooked screws later although you thought that you drove screws properly. In this case, you pull out the screw and again drive a screw. It is very annoying. The screw-driving guide is usually fixated to the bottom of the driver handle. When you need to drive a screw 90 degrees, you can separate the guide from the handle and lower it downward and hold it vertically to the surface to be screwed. If you do so, you can drive a screw neatly 90 degrees.
