That would be more convenient, but I am worried that the damping coefficient will change after a long time. The self-locking key is for more accurate data ~
Why not mark the length of the entire tape measure shell, and directly add the tape measure to measure the length is the result? Why do you want to open a window and make a red line at the bottom......?
Please ask, can a ruler bend when pulled out for about 1 meter? I don't know English very well (laughing and crying)
The tape measure itself has its own damping, and it is more convenient to design the self-locking key directly into one key for recycling.
