تعريف adjustable pliers في الإنجليزية الإنجليزية القاموس.
Tongue-and-groove pliers, also known as water pump pliers, adjustable pliers, groove-joint pliers,Multi-Grips, and Channellocks, are a type of slip-joint pliers. They have serrated jaws generally set 45– to 60-degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles for increased leverage
