Distinguishing method of left and right rotation of spring:
The left-right rotation of the spring is the same as the left-hand and right-hand screws. If it is a compression spring, the left-hand and right-hand rotation are the same, but the right-hand spring is still the main one; However, if it is a torsion spring, the left-hand rotation and the right-hand rotation are different, because the torsion of the two is exactly opposite.
1. The upper end of the left hand grip spring is in the same direction as the index finger tip of the left hand, which is left-handed.
2. The right hand holds the spring, and the upper end is in the same direction as the index finger tip of the right hand, which is right-handed.
3. And the thread identification method should be the same. The left is left-handed, the right is right-handed!
4. See which side is high after leveling.
5. Cut along the axial center line, facing the view, the high one on the left is left-handed, and the high one on the right is right-handed.
