3 application skills
1) when using a removable wrench to pull the big nut, a relatively large torque must be used, and the hand is best held close to the end of the handle.

(2) it doesn't need too much torque when using the movable spanner to pull the smaller nut, but since the nut is too small and prone to skid, it is better to hold the hand close to the head of the movable spanner, so that it is more convenient to adjust the worm wheel, and at the same time, you can tighten the movable lever lip to avoid slipping.

(3) the movable wrench must not be used in the opposite direction, because it will damage the movable wrench lip. Meanwhile, the long handle with steel tube can not be used to exert large pulling torque.

(4) the movable wrench has its own function. Do not use it to make pry bar and hammer.
