Generally the wrenches used in family are solid wrenches and active wrenches. The wrench has two kinds, single and double head wrench. The opening is adapted to the size of screw head and nut and is made according to the standard size. An active wrench is a tool that tightens or loosens a corner screw or nut. There are three types of active wrenches commonly used by electricians, 200mm, 250mm and 300mm wrench. The wrench should be selected according to the size of the nut. When used, handle the handle on the right hand. When the wrench is used to move the small nut, the hand should be held near the pull lip, and the worm should be adjusted to adapt to the size of the nut, because of the need to constantly turn the worm wheel and adjust the size of the drawer. When the wrench of the active wrench clamps the nut, it is on the upper lip and the upper lip is under it. The active wrench cannot be used in turn.

 

The plier commonly used in family is vise. The vise is also called the wire pliers. There are teeth and toothless vice, the teeth vice is used to increase the friction. It can more firmly grip things, but it may cause damage when griping soft items. Do not use the pliers as a hammer during use.
