What are the requirements for using an adjustable spanner?

(1) When turning the large nut, a large torque is often used, and the hand should be held near the end of the handle.

(3) The adjustable wrench cannot be turned over to avoid damaging the lip, and the steel tube cannot be used to extend the handle to increase the torque.
