I was looking for a small air duster nozzle with a rubber nozzle. Although it was not possible for the tip to come off, fine adjustment is difficult. (I am surprised when air is blown.) I removed the switch pin that pulls out the air and used a rubber cushion to bite. I was able to adjust it.
It is small and useful for cleaning a little during inspection. Although there is an air hose but there is no gun, however, it is a drawback that the long rubber sometimes escapes and flies. I want another idea.
