Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing.

[0024] figure 1 A pliers 10 according to the invention is shown. The pliers 10 includes a pliers head 2 and a pliers handle 3 . The pliers 2 includes a first pliers part 21 and a second pliers part 22 . The pliers handle 3 includes a first pliers handle 31 connected to the first pliers head 21 , and a second pliers handle 32 connected to the second pliers head 22 . Wherein, the first and second pliers handles 31, 32 can be connected through a ratchet or hinge structure. When the first pliers handle part 31 and the second pliers handle part 32 move apart, the first pliers head part 21 and the second pliers head part 22 can be separated from each other. When the first pliers handle part 31 and the second pliers handle part 32 make a combined movement, the first pliers head part 21 and the second pliers head part 22 can merge with each other.

Abstract

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.

Description

technical field [0001] The invention relates to a pair of pliers, in particular to a pair of pliers for clamping flat metal terminals. Background technique [0002] The metal terminal is essentially a metal tube. When the wire is inserted into one end of the metal terminal, the end of the metal terminal can be clamped flat with flat nose pliers or needle-nose pliers, so that the wire can be firmly fixed on the metal terminal Inside. [0003] The jaws of the existing intact and undamaged flat-nose pliers and needle-nose pliers are all in a straight shape, but after frequent use, the jaws will become V-shaped due to wear and tear. When the operator uses a V-shaped flat-nose pliers or When the needle-nose pliers clamp flat metal terminals, due to the insufficient clamping force of the pliers, the deformation of the metal terminals is insufficient, and it is difficult to firmly fix the wires, making the wires easy to come out, resulting in an open circuit phenomenon.
