Tips: Working principle and use method of screwdriver

1. Working Principle of screwdriver

Screwdriver works based on the lever principle. Its power comes from the handle grip. With the handle rotation, drive the screwdriver shaft to drive the screw rotation. The bigger the handle, the less effort. This is the obvious lever mechanism.

2. Common usage of screwdriver

• The use of short screwdriver
  The short screwdriver is used to tighten the small screws on the wiring pile of the electrical equipment. The thumb and middle finger can be used to hold the handle, and the forefinger is used to hold the end of the handle to rotate.
• The use of long screwdriver
  Long screwdriver is used to tighten the larger screws. When the screwdriver is used, in addition to gripping the handle with the thumb, index finger and middle finger, the palm holds against the end of the handle, so as to prevent the slip during the rotation.
• The use of a longer screwdriver
  You can use the right hand to press and turn the handle, and the left hand to hold the center of the screwdriver, which should not be placed around the screwdriver, in case the head slip will scratch the hand.
