Extension of Allen key
The extended Allen key of the Allen key is also called Allen key. Common English names include "Allen key (or Allen wrench)" and "Hex key" (or Hex wrench). It exerts the force on the screw through torque, greatly reducing the strength of the user, and is an indispensable tool in the industrial manufacturing industry. Sometimes, we always look at the Allen wrench in our hand, but we have no way to start the screw. So in order to solve this problem, we need to take measures, generally lengthening the hexagonal wrench. The hexagon socket wrench is lengthened, so we can easily reach the places that are difficult to reach, align the screw, and directly tighten it a few times to solve the problem, which is very convenient. In addition to making it easy for us to reach places that are difficult to reach, there is another reason for lengthening the hexagonal wrench, that is, lengthening the lever arm to facilitate the removal of some relatively tight screws. By lengthening the arm of force, we can turn tighter screws with less force. Although it is not as exaggerated as using a fulcrum to pry the earth, it does provide us with great convenience. This is why the Allen wrench should be lengthened. Are you right. A simple change brings us infinite convenience, especially for the hexagonal wrench, a long rod can be applied to more occasions.
