Pliers

The invention relates to a pair of pliers, which comprises a pliers head and a pliers handle, wherein the pliers head is provided with a first pliers element and a second pliers element, a first pliers jaw element and a second pliers jaw element are respectively arranged on the first pliers head element and the second pliers head element, the first pliers jaw element is provided with a first clamping surface, the second pliers jaw element is provided with a second clamping surface, a convex strip is arranged on the first clamping surface, and a groove is formed in the second clamping surface, wherein when the first pliers head element is combined with the second pliers head element, the convex strip can enter the groove, and when the first pliers head element is separated from the second pliers head element, the convex strip can be moved out from the groove. The pliers provided by the invention have the advantages that a metal wiring terminal is flatted through clamping by the convex strip and the groove, and the flattening clamping mode can ensure that the metal wiring terminal can still be effectively flattened through clamping after the pliers are frequently used, so that a conducting wire can be firmly fixed in the metal wiring terminal, and the occurrence of an open circuit phenomenon is prevented.
